The present invention relates to novel 4′4′-dioxaspiro-spirocyclically substituted tetramates, to a plurality of processes for their preparation and to their use as pesticides and/or herbicides. The invention also provides selectively herbicidal compositions comprising, firstly, the 4′4′-dioxaspiro-spirocyclically substituted tetramates and, secondly, a crop plant compatibility-improving compound.
The present invention also relates to novel water-soluble concentrates (SL formulations) of 4′4′-dioxaspiro-spirocyclically substituted tetramates and their enols, to processes for preparing these formulations and to their use as pesticides and/or herbicides.
The present invention furthermore relates to the boosting of the action of crop protection compositions comprising, in particular, 4′4′-dioxaspiro-spirocyclically substituted tetramates, through the addition of ammonium salts or phosphonium salts and optionally penetrants, to the corresponding compositions, to processes for producing them and to their application in crop protection as insecticides and/or acaricides and/or for preventing unwanted plant growth.
For 3-acylpyrrolidine-2,4-diones pharmaceutical properties have been previously described (S. Suzuki et al. Chem. Pharm. Bull. 15 1120 (1967)). Furthermore, N-phenylpyrrolidine-2,4-diones have been synthesized by R. Schmierer and H. Mildenberger (Liebigs Ann. Chem. 1985, 1095). Biological activity of these compounds has not been described.
EP-A-0 262 399 and GB-A-2 266 888 disclose similarly structured compounds (3-arylpyrrolidine-2,4-diones) for which, however, no herbicidal, insecticidal or acaricidal action has been disclosed. Known compounds with herbidical, insecticidal or acaricidal action are unsubstituted bicyclic 3-arylpyrrolidine-2,4-dione derivatives (EP-A-355 599, EP-A-415 211 and JP-A-12-053 670) and also substituted monocyclic 3-arylpyrrolidine-2,4-dione derivatives (EP-A-377 893 and EP-A-442 077).
Additionally known are polycyclic 3-arylpyrrolidine-2,4-dione derivatives (EP-A-442 073) and 1H-arylpyrrolidinedione derivatives (EP-A-456 063, EP-A-521 334, EP-A-596 298, EP-A-613 884, EP-A-613 885, WO 95/01 997, WO 95/26 954, WO 95/20 572, EP-A-0 668 267, WO 96/25 395, WO 96/35 664, WO 97/01 535, WO 97/02 243, WO 97/36 868, WO 97/43275, WO 98/05638, WO 98/06721, WO 98/25928, WO 99/24437, WO 99/43649, WO 99/48869 and WO 99/55673, WO 01/17972, WO 01/23354, WO 01/74770, WO 03/013249, WO 03/062244, WO 2004/007448, WO 2004/024 688, WO 04/065366, WO 04/080962, WO 04/111042, WO 05/044791, WO 05/044796, WO 05/048710, WO 05/049569, WO 05/066125, WO 05/092897, WO 06/000355, WO 06/029799, WO 06/056281, WO 06/056282, WO 06/089633, WO 07/048545, DE-A-102005059892, WO 07/073856, WO 07/096058, WO 07/121868, WO 07/140881, WO 08/067873, WO 08/067910, WO 08/067911, WO 08/138551, PCT/EP2008/005973 and EP 07117104). Furthermore known are ketal-substituted 1-H-arylpyrrolidine-2,4-diones from WO 99/16748 and (spiro)-ketal-substituted N-alkoxyalkoxy-substituted arylpyrrolidinediones from JP-A-14 205 984 and Ito M. et. al., Bioscience, Biotechnology and Biochemistry 67, 1230-1238, (2003). The addition of safeners to ketoenols is also known in principle from WO 03/013249. Moreover, WO 06/024411 and PCT/EP2008/005185 disclose herbicidal compositions comprising ketoenols.
However, the herbicidal and/or acaricidal and/or insecticidal activity and/or activity spectrum and/or the plant compatibility of the known compounds, in particular with respect to crop plants, is/are not always satisfactory.
The present invention now provides novel compounds of the formula (I)
in which
Depending inter alia on the nature of the substituents, the compounds of the formula (I) may be present as geometrical and/or optical isomers or isomer mixtures of varying composition which, if appropriate, may be separated in a customary manner. The present invention provides the pure isomers and the tautomer and isomer mixtures, their preparation and use and materials comprising them. However, for the sake of simplicity, hereinbelow only compounds of the formula (I) are referred to, although what is meant are both the pure compounds and, if appropriate, mixtures having various proportions of isomeric and tautomeric compounds.
Furthermore, it has been found that the novel compounds of the formula (I) are obtained by one of the processes described below:
Furthermore, it has been found that the novel compounds of the formula (I) are very effective as pesticides, preferably as insecticides, acaricides and/or herbicides.
Surprisingly, it has now also been found that 4′4′-dioxaspiro-spirocyclically substituted tetramates, when used together with the crop plant compatibility-improving compounds (safeners/antidotes) described below, efficiently prevent damage to the crop plants and can be used in a particularly advantageous manner as broad-spectrum combination preparations for the selective control of unwanted plants in crops of useful plants, such as, for example, in cereals, but also in maize, soya beans and rice.
The invention also provides selective herbicidal materials comprising an effective amount of an active compound combination comprising, as components,
or of the general formula (IIb)
or of the formula (IIc)
where
or of the general formula (IIe)
where
Furthermore, it has been found that compositions comprising a phase comprising at least one dissolved active compound of the formula (I) or (I′)
in which
A, B, G, m, n, W, X, Y and Z have the meaning given above
on application following dilution at pH values of ≧5 to suitable concentrations have a more rapid onset of action and/or better compatibility with crop plants and/or higher activity than, for example, corresponding SC formulations.
This is particularly surprising since, owing to the relatively high solubility in water of the active compounds of the formula (I′) at pH values of ≧5, starting from any formulation type following dilution with water concentrations are reached which are significantly lower than the expected solubility of the active compound in water—the activity thus being independent of the original formulation type. Of course, the solubility kinetics are also a relevant parameter in the preparation of the spray liquor. However, the person skilled in the art would expect a formulation which, in addition to the active compound, also comprises higher concentrations of surfactants, to have higher solubility kinetics. Surprisingly, this has not been found.
In the formulations according to the invention, the active compounds of the formula (I) are in dissolved form even in the concentrated compositions.
Accordingly, the present invention provides compositions comprising at least one solvent and at least one compound of the formula (I) or (I′) in dissolved form.
The present invention also provides processes for preparing water-soluble concentrates comprising at least one compound of the formula (I) or (I′).
Moreover, the present invention provides the use of compositions comprising a phase comprising at least one compound of the formula (I) or (I′) in dissolved form for controlling unwanted plant growth and/or animal pests.

In addition to the compounds mentioned in the Preparation Examples, the following compounds of the formula (I) may be specifically mentioned:
Preferred meanings of the groups listed above in connection with the crop plant compatibility-improving compounds (“herbicide safeners”) of the formulae (IIa), (IIb), (IIc), (IId) and (IIe) are defined below.
Examples of the compounds of the formula (IIa) which are very particularly preferred as herbicide safeners according to the invention are listed in the table below.
Examples of the compounds of the formula (IIb) which are very particularly preferred as herbicide safeners according to the invention are listed in the table below.

Examples of the compounds of the formula (ad) which are very particularly preferred as herbicide safeners according to the invention are listed in the table below.
Examples of the compounds of the formula (IIe) which are very particularly preferred as herbicide safeners according to the invention are listed in the table below.
Most preferred as crop plant compatibility-improving compound [component (b′)] are cloquintocet-mexyl, fenchlorazole-ethyl, isoxadifen-ethyl, mefenpyr-diethyl, furilazole, fenclorim, cumyluron, dymron, dimepiperate and the compounds IIe-5 and IIe-11, and particular emphasis is given to cloquintocet-mexyl and mefenpyr-diethyl.
The compounds of the general formula (IIa) to be used as safeners according to the invention are known and/or can be prepared by processes known per se (cf. WO-A-91/07874, WO-A-95/07897).
The compounds of the general formula (IIb) to be used as safeners according to the invention are known and/or can be prepared by processes known per se (cf. EP-A-191736).
The compounds of the general formula (IIc) to be used as safeners according to the invention are known and/or can be prepared by processes known per se (cf. DE-A-2218097, DE-A-2350547).
The compounds of the general formula (IId) to be used as safeners according to the invention are known and/or can be prepared by processes known per se (cf. DE-A-19621522/U.S. Pat. No. 6,235,680).
The compounds of the general formula (IIe) to be used as safeners according to the invention are known and can be prepared by processes known per se (cf. WO-A-99/66795/U.S. Pat. No. 6,251,827).
Examples of the selectively herbicidal combinations according to the invention comprising in each case one active compound of the formula (I) and in each case one of the safeners defined above are listed in the table below.
Surprisingly, it has now been found that the active compound combinations defined above of 4′4′-dioxaspiro-spirocyclically substituted tetramates of the general formula (I) and safeners (antidotes) from the group (b′) set out above combine very good useful plant tolerance with a particularly high herbicidal activity and can be used in various crops, in particular in cereals (especially wheat), but also in soya, potatoes, maize and rice, for the selective control of weeds.
In this context it is to be considered surprising that, from a multiplicity of known safeners or antidotes capable of antagonizing the damaging effect of a herbicide on the crop plants, it is specifically the compounds of group (b′) set out above which are suitable for compensating—almost completely—the damaging effect of 4′4′-dioxaspiro-spirocyclically substituted tetramates on the crop plants, without at the same time having any critical adverse effect on the herbicidal activity against the weeds.
Emphasis may be given here to the particularly advantageous effect of the particularly preferred and most preferred combination partners from group (b′), in particular with regard to the gentle treatment of cereal plants, such as wheat, barley and rye, for example, but also maize and rice, as crop plants.
All the active compounds of the formula (I) present in the materials according to the invention can be prepared by processes described in the prior art (see references mentioned above). Their activity is good; however, in particular at low application rates and concentrations, it is not always satisfactory. Furthermore, the compatibility of these compounds with plants is not always sufficient. Accordingly, there is a need for a boost of action and/or an improved compatibility with plants with respect to crop plants of the crop protection compositions comprising the compounds.
In the literature it has already been described how the action of various active compounds can be boosted by addition of ammonium salts. The salts in question, however, are detersive salts (for example WO 95/017817) or salts which have relatively long alkyl substituents and/or aryl substituents and which have a permeabilizing action or which increase the active compound's solubility (for example EP-A 0 453 086, EP-A 0 664 081, FR-A 2 600 494, U.S. Pat. No. 4,844,734, U.S. Pat. No. 5,462,912, U.S. Pat. No. 5,538,937, US-A 03/0224939, US-A 05/0009880, US-A 05/0096386). Moreover, the prior art describes the action only for particular active compounds and/or particular applications of the corresponding compositions. A boost to action by ammonium sulphate, for example, is described by way of example for the herbicides glyphosate and phosphinothricin (U.S. Pat. No. 6,645,914, EP-A2 0 036 106).
The use of ammonium sulphate as a formulating assistant has also been described for certain active compounds and applications (WO 92/16108), but its purpose therein is to stabilize the formulation, not to boost the action.
Herbicidal and insecticidal compositions of cyclic ketoenols with ammonium salts or phosphonium salts for boosting the action are described in WO 07/068,427 and WO 07/068,428.
Surprisingly, it has now been found that the activity of herbicides and/or acaricides and/or insecticides from the class of the 4′4′-dioxaspiro-spirocyclically substituted tetramates can be increased significantly by adding ammonium salts or phosphonium salts to the application solution or by incorporating these salts into a formulation comprising 4′4′-dioxaspiro-spirocyclically substituted tetramates. The present invention therefore provides for the use of ammonium salts and/or phosphonium salts to boost the activity of crop protection compositions which comprise insecticidally and/or acaricidally and/or herbicidally active 4′4′-dioxaspiro-spirocyclically substituted tetramates as active compound. The invention also provides materials which comprise insecticidally and/or acaricidally and/or herbicidally active 4′4′-dioxaspiro-spirocyclically substituted tetramates and action-boosting ammonium or phosphonium salts, including specifically not only formulated active compounds but also ready-to-use materials (spray liquors). The invention additionally provides, finally, for the use of these materials for controlling insects and/or spider mites and/or unwanted plant growth.
The active compounds can be used in the compositions of the invention in a broad concentration range. The concentration of the active compounds in the formulation is typically 0.1%-50% by weight.
Ammonium salts and phosphonium salts which inventively boost the activity of crop protection compositions comprising 4′4′-dioxaspiro-spirocyclically substituted tetramates are defined by formula (II′)
in which
The ammonium salts and phosphonium salts of the formula (II') can be used in a broad concentration range to boost the activity of crop protection compositions comprising compounds of the formula (I). In general the ammonium salts or phosphonium salts are used in the ready-to-use crop protection composition in a concentration of 0.5 to 80 mmol/l, preferably 0.75 to 37.5 mmol/l, more preferably 1.5 to 25 mmol/l. In the case of a formulated product the ammonium salt and/or phosphonium salt concentration in the formulation is chosen such that it is within these stated general, preferred or particularly preferred ranges after the formulation has been diluted to the desired active-compound concentration. The concentration of the salt in the formulation is typically 1%-50% by weight.
In one preferred embodiment of the invention the activity is boosted by adding to the crop protection compositions not only an ammonium salt and/or phosphonium salt but also, additionally, a penetrant. It is considered entirely surprising that even in these cases an even greater boost to activity is observed. The present invention therefore also provides for the use of a combination of penetrant and ammonium salts and/or phosphonium salts to boost the activity of crop protection compositions which comprise herbicidally active 4′4′-dioxaspiro-spirocyclically substituted tetramates as active compound. The invention also provides materials which comprise insecticidally and/or acaricidally and/or herbicidally active 4′4′-dioxaspiro-spirocyclically substituted tetramates, penetrants and ammonium salts and/or phosphonium salts, including specifically not only formulated active compounds but also ready-to-use materials (spray liquors). The invention additionally provides, finally, for the use of these materials for controlling insects and/or spider mites and/or unwanted plant growth.
Suitable penetrants in the present context include all those substances which are typically used to enhance the penetration of active agrochemical compounds into plants. Penetrants are defined in this context by their ability to penetrate from the aqueous spray liquor and/or from the spray coating into the cuticle of the plant and thereby to increase the mobility of active compounds in the cuticle. The method described in the literature (Baur et al., 1997, Pesticide Science 51, 131-152) can be used in order to determine this property.
Suitable penetrants are, for example, alkanol alkoxylates. Penetrants according to the invention are alkanol alkoxylates of the formula
R—O—(-AO)v—R′ (III′)
in which
Here, alkanol alkoxylates in which R′ represents hydrogen are referred to as “open” alkanol alkoxylates. A preferred group of penetrants are alkanol alkoxylates of the formula
R—O—(-EO—)n—R′ (III′-a)
in which
A further preferred group of penetrants are alkanol alkoxylates of the formula
R—O—(-EO—)p—(—PO—)q—R′ (III′-b)
in which
A further preferred group of penetrants are alkanol alkoxylates of the formula
R—O—(—PO—)r-(EO—)s—R′ (III′-c)
in which
A further preferred group of penetrants are alkanol alkoxylates of the formula
R—O—(-EO—)p—(—BO—)q—R′ (III′-d)
in which
A further preferred group of penetrants are alkanol alkoxylates of the formula
R—O—(—BO—)r—(-EO—)s—R′ (III′-e)
in which
A further preferred group of penetrants are alkanol alkoxylates of the formula
CH3—(CH2)t—CH2—O—(—CH2—CH2—O—)u—R′ (III′-f)
in which
In the formulae indicated above,
As an example of an alkanol alkoxylate of the formula (III-c) mention may be made of 2-ethylhexyl alkoxylate of the formula
in which
and
the numbers 8 and 6 represent average values.
As an example of an alkanol alkoxylate of the formula (III-d) mention may be made of the formula
CH3—(CH2)10—O—(-EO—)6—(—BO—)2—CH3 (III′-d-1)
in which
and
Particularly preferred alkanol alkoxylates of the formula (III′-f) are compounds of this formula in which
Mention may be made with very particular preference of alkanol alkoxylate of the formula (III′-f-1)
CH3—(CH2)t—CH2—O—(—CH2—CH2—O—)u—H (III′-f-1)
in which
A general definition of the alkanol alkoxylates is given by the formulae above. These substances are mixtures of compounds of the stated type with different chain lengths. The indices therefore have average values which may also deviate from whole numbers.
The alkanol alkoxylates of the formulae stated are known and in some cases are available commercially or can be prepared by known methods (cf. WO 98/35 553, WO 00/35 278 and EP-A 0 681 865).
Suitable penetrants also include, for example, substances which promote the availability of the compounds of the formula (I) in the spray coating. These include, for example, vegetable oils, mineral oils, paraffin oils and fatty acid esters.
Vegetable oils are generally known and commercially available. The term vegetable oils is to be understood as including, for example, oils from oleaginous plant species, such as soya bean oil, rapeseed oil, maize germ oil, maize kernel oil, sunflower oil, cottonseed oil, linseed oil, coconut oil, palm oil, thistle oil, walnut oil, arachis oil, olive oil, castor oil or colza oil, in particular soya bean oil, rapeseed oil, maize germ oil or sunflower oil and mixtures thereof. The vegetable oils (triglycerides) are preferably esters of C10-C22—, preferably C12-C20—, fatty acids of glycerol. The C10-C22-fatty acid esters of glycerol are, for example, esters of unsaturated or saturated C12-C20— fatty acids, in particular those having an even number of carbon atoms, for example erucic acid, lauric acid, palmitic acid, and in particular C18-fatty acids, such as stearic acid, oleic acid, linoleic acid or linolenic acid.
Suitable mineral oils are various commercially available distillate fractions of mineral oil (petroleum). Preference is given to mixtures of open-chain C14-C30-hydrocarbons, cyclic hydrocarbons (naphthenes) and aromatic hydrocarbons. The hydrocarbons can be either straight-chain or branched. Particular preference is given to mixtures having an aromatic portion of less than 8% by weight. Very particular preference is given to mixtures having an aromatic portion of less than 4% by weight.
Suitable paraffin oils are straight-chain and branched C14-C30-hydrocarbons. Paraffin oils are also known as base oil or white oil and are commercially available, for example, as Bayol® 85 (Exxon Mobil, Machelen, Belgium), Marcol® 82 (Exxon Mobil, Machelen, Belgium), BAR 0020 (RA.M.oil S.p.A., Naples, Italy), Pionier 0032-20 (Hansen & Rosenthal KG, Hamburg, Germany) or, for example, Kristol M14 (Carless, Surrey, England).
Suitable fatty acid esters are alkyl fatty acid esters, such as C1-C20-alkyl C10-C22-fatty acid esters. Preference is given to methyl esters, ethyl esters, propyl esters, butyl esters, 2-ethylhexyl esters and dodecyl esters. Particular preference is given to methyl esters and ethyl esters. Examples of synthetic fatty acid esters are, for example, those which are derived from fatty acids having an odd number of carbon atoms, such as C11-C21-fatty acid esters. The transesterification can be carried out by known methods, as described, for example, in Römpp Chemie Lexikon, 9th Edition, Volume 2, page 1343, Thieme Verlag, Stuttgart. In the adjuvant compositions according to the invention, the fatty acid esters can be present in the form of commercially available esters, in particular esters such as rapeseed oil methyl ester, for example Edenor® MESU (Cognis, Germany) or the Agnique® ME series (Cognis, Germany) or in the form of commercially available oil-containing formulation additives, in particular those based on rapeseed oil methyl ester or rapeseed oil ethyl ester, for example Hasten® (Victoria Chemicals, Australia), Actirob® B (Novance, France) or Stefes Mero® (Stefes, Germany).
The concentration of penetrant in the materials according to the invention can be varied within a wide range. In the case of a formulated crop protection composition it is in general 1% to 95%, preferably 1% to 55%, more preferably 15%-40% by weight. In the ready-to-use materials (spray liquors) the concentrations are generally between 0.1 and 10 g/l, preferably between 0.5 and 5 g/l.
Inventively emphasized combinations of active compound, salt and penetrant are listed in the table below. “As per test” means here that any compound that acts as a penetrant in the cuticle penetration test (Baur et al., 1997, Pesticide Science 51, 131-152) is suitable.
Suitable for use as solvents in the compositions according to the invention are all water-miscible solvents which are customarily mentioned for agrochemical formulations and in which the active compounds of the formulae (I) and (I′) are soluble at the concentrations used herein. Examples which may be mentioned are water, alcohols, such as methanol, ethanol or isopropanol, ethers or polyethers, such as 1,4-dioxane, tetrahydrofuran or dimethoxyethane, amides, such as formamide, acetamide, N,N-dimethylformamide, N,N-dimethylacetamide or Hallcomid® (mixture of 50-60% N,N-dimethyloctanamide and 35-45% N,N-dimethyldecanamide), sulphoxides/sulphones, such as dimethyl sulphoxide or sulpholane, and lactones/lactams, such as N-methylpyrrolidone and gamma-butyrolactone.
The preferred solvent is water.
To prepare the water-soluble concentrates according to the invention comprising a compound of the formula (I), it is advantageous to generate the compound of the formula (I) in situ during the preparation of the composition by reacting the corresponding compound of the formula (I′) with a suitable base.
This process allows the preparation of compositions comprising compounds of the formula (I) whose stability in isolated form is sometimes lower. Suitable bases are, in principle, all organic and inorganic bases, provided their use for agricultural purposes is acceptable.
Examples of bases are
In principle, the base may also be used in immobilized form, where the carrier material may be removed, for example by filtration, after the preparation of the concentrate according to the invention.
If required—based on the amount of the compounds of the general formula (I′) used—between 0.1 and 100 molar equivalents, typically from 0.5 to 3 molar equivalents, of the base may be employed.
Preferred as basic auxiliaries are lithium hydroxide, sodium hydroxide, potassium hydroxide, magnesium hydroxide, calcium hydroxide and also ammonia, basic ammonium salts (such as for example diammonium hydrogen phosphate) alkylamines and hydroxyalkylamines.

In the ready-to-use formulations (spray liquors), the content of surfactant is generally from 0.1 to 10 g/l, preferably from 0.3 to 3 g/l.
The surfactant is generally applied at an application rate of from 20 to 1000 g of a.i./ha, preferably from 100 to 300 g of a.i/ha.
Using, for example, according to process (A) ethyl N-(2,6-dimethyl-4-chloro-4,4-ethylenedioxy-phenylacetyl)-1-aminocyclohexanecarboxylate as starting material, the course of the process according to the invention can be represented by the reaction scheme below:

In certain concentrations, or at certain application rates, the compounds/active compound combinations according to the invention can, if appropriate, also be used as herbicides, safeners, growth regulators or agents for improving the plant characteristics, or as microbicides, for example as fungicides, antimycotics, bactericides, viricides (including as agents against viroids) or as agents against MLOs (mycoplasma-like organisms) and RLOs (rickettsia-like organisms). If appropriate, they can also be used as intermediates or precursors for the synthesis of other active compounds.
According to the invention, it is possible to treat all plants and parts of plants. Plants are to be understood here as meaning all plants and plant populations such as desired and undesired wild plants or crop plants (including naturally occurring crop plants). Crop plants can be plants which can be obtained by conventional breeding and optimization methods or by biotechnological and genetic engineering methods or combinations of these methods, including the transgenic plants and including the plant cultivars which can or cannot be protected by plant breeders' certificates. Parts of plants are to be understood as meaning all above-ground and below-ground parts and organs of plants, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stems, trunks, flowers, fruit-bodies, fruits and seeds and also roots, tubers and rhizomes. Parts of plants also include harvested plants and vegetative and generative propagation material, for example seedlings, tubers, rhizomes, cuttings and seeds.
The treatment according to the invention of the plants and parts of plants with the active compounds/active compound combinations is carried out directly or by action on their environment, habitat or storage area according to customary treatment methods, for example by dipping, spraying, evaporating, atomizing, broadcasting, brushing-on, injecting and, in the case of propagation material, in particular in the case of seeds, furthermore by one- or multi-layer coating.
The active compounds/active compound combinations can be converted into the customary formulations such as solutions, emulsions, wettable powders, water- and oil-based suspensions, powders, dusts, pastes, soluble powders, soluble granules, granules for broadcasting, suspension-emulsion concentrates, natural and synthetic materials impregnated with active compound, fertilizers and also microencapsulations in polymeric materials.
These formulations are produced in a known manner, for example by mixing the active compounds/active compound combinations with extenders, that is, liquid solvents and/or solid carriers, optionally with the use of surfactants, that is, emulsifiers and/or dispersants, and/or foam formers.
If the extender used is water, it is also possible, for example, to use organic solvents as cosolvents. The following are essentially suitable as liquid solvents: aromatics such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example mineral oil fractions, mineral and vegetable oils, alcohols such as butanol or glycol and their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide and dimethyl sulphoxide, or else water.
Suitable solid carriers are:
for example ammonium salts and ground natural minerals such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals such as highly disperse silica, alumina and silicates; suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, or else synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; suitable emulsifiers and/or foam formers are: for example nonionic and anionic emulsifiers such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates, or else protein hydrolysates; suitable dispersants are: for example lignosulphite waste liquors and methylcellulose.
Tackifiers such as carboxymethylcellulose, natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Other possible additives are mineral and vegetable oils.
It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.
The formulations generally comprise between 0.1 and 95% by weight of active compound, preferably between 0.5 and 90%.
The active compound/active compound combination according to the invention can be present in its commercially available formulations and in the use forms, prepared from these formulations, as a mixture with other active compounds, such as insecticides, attractants, sterilants, bactericides, acaricides, nematicides, fungicides, growth-regulating substances, herbicides, safeners, fertilizers or semiochemicals.
A mixture with other known active compounds such as herbicides, fertilizers, growth-regulating substances, safeners, semiochemicals, or else with agents to improve the properties of the plant, is also possible.
When used as insecticides, the active compounds/active compound combinations according to the invention can furthermore be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with synergists. Synergists are compounds which increase the action of the active compounds, without it being necessary for the synergist added to be active itself.
When used as insecticides, the active compounds/active compound combinations according to the invention can furthermore be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with inhibitors which reduce degradation of the active compound after use in the environment of the plant, on the surface of parts of plants or in plant tissues.
The active compound content of the use forms prepared from the commercially available formulations can vary within wide limits. The active compound concentration of the use forms can be from 0.00000001 to 95% by weight of active compound, preferably between 0.00001 and 1% by weight.
Application is carried out in a customary manner appropriate for the use forms.
As already mentioned above, it is possible to treat all plants and their parts according to the invention. In a preferred embodiment, wild plant species and plant cultivars, or those obtained by conventional biological breeding methods, such as crossing or protoplast fusion, and parts thereof, are treated. In a further preferred embodiment, transgenic plants and plant cultivars obtained by genetic engineering methods, if appropriate in combination with conventional methods (Genetically Modified Organisms), and parts thereof are treated. The terms “parts”, “parts of plants” and “plant parts” have been explained above.
The method of treatment according to the invention is preferably used on genetically modified organisms, for example plants or plant parts.
Genetically modified plants (or transgenic plants) are plants in which a heterologous gene has been stably integrated into the genome.
The expression “heterologous gene” essentially means a gene which is provided or assembled outside the plant and when introduced in the nuclear, chloroplastic or mitochondrial genome gives the transformed plant new or improved agronomic or other properties by expressing a protein or polypeptide of interest or by downregulating or silencing other gene(s) which are present in the plant (using for example, antisense technology, cosuppression technology or RNA interference—RNAi—technology). A heterologous gene that is located in the genome is also called a transgene. A transgene that is defined by its particular location in the plant genome is called a transformation or transgenic event.
Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, diet), the treatment according to the invention may also result in superadditive (“synergistic”) effects. Thus, for example, the following effects, which exceed the effects which were actually to be expected, are possible: reduced application rates and/or a widening of the activity spectrum and/or an increase in the activity of the active compounds and compositions which can be used according to the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, increased flowering performance, easier harvesting, accelerated maturation, higher harvest yields, bigger fruits, larger plant height, greener leaf colour, earlier flowering, higher quality and/or a higher nutritional value of the harvested products, higher sugar concentration within the fruits, better storage stability and/or processability of the harvested products.
At certain application rates, the active compounds/active compound combinations according to the invention may also have a strengthening effect in plants. Accordingly, they are also suitable for mobilizing the defence system of the plant against attack by unwanted phytopathogenic fungi and/or microorganisms and/or viruses. This may, if appropriate, be one of the reasons for the enhanced activity of the combinations according to the invention, for example against fungi. Plant-strengthening (resistance-inducing) substances are to be understood as meaning, in the present context, those substances or combinations of substances which are capable of stimulating the defence system of plants in such a way that, when subsequently inoculated with unwanted phytopathogenic fungi and/or microorganisms and/or viruses, the treated plants display a substantial degree of resistance to these unwanted phytopathogenic fungi and/or microorganisms and/or viruses. In the present case, unwanted phytopathogenic fungi and/or microorganisms and/or viruses are to be understood as meaning phytopathogenic fungi, bacteria and viruses. Thus, the substances according to the invention can be employed for protecting plants against attack by the abovementioned pathogens within a certain period of time after the treatment. The period of time within which protection is effected generally extends from 1 to 10 days, preferably 1 to 7 days, after the treatment of the plants with the active compounds.
Plants which are also preferably treated according to the invention are resistant against one or more biotic stresses, i.e. said plants have a better defence against animal and microbial pests, such as against nematodes, insects, mites, phytopathogenic fungi, bacteria, viruses and/or viroids.
In addition to the plants and plant cultivars mentioned above, the treatment according to the invention may also be applied to those which are resistant to one or more abiotic stress factors.
Abiotic stress conditions may include, for example, drought, cold temperature exposure, heat exposure, osmotic stress, flooding, increased soil salinity, increased mineral exposure, ozone exposure, high light exposure, limited availability of nitrogen nutrients, limited availability of phosphorus nutrients or shade avoidance.
Plants and plant cultivars which may also be treated according to the invention, are those plants characterized by enhanced yield characteristics. Increased yield in said plants can be the result of for example, improved plant physiology, growth and development, such as water use efficiency, water retention efficiency, improved nitrogen use, enhanced carbon assimilation, improved photosynthesis, increased germination efficiency and accelerated maturation. Yield can furthermore by affected by improved plant architecture (under stress and non-stress conditions), including early flowering, flowering control for hybrid seed production, seedling vigour, plant size, internode number and distance, root growth, seed size, fruit size, pod size, pod or ear number, seed number per pod or ear, seed mass, enhanced seed filling, reduced seed dispersal, reduced pod dehiscence and lodging resistance. Further yield traits include seed composition, such as carbohydrate content, protein content, oil content and composition, nutritional value, reduction in anti-nutritional compounds, improved processability and better storage stability.
Plants that may be treated according to the invention are hybrid plants that already express the characteristic of heterosis or the hybrid effect which results in generally higher yield, vigour, health and resistance towards biotic and abiotic stress factors. Such plants are typically made by crossing an inbred male sterile parent line (the female parent) with another inbred male fertile parent line (the male parent). Hybrid seed is typically harvested from the male sterile plants and sold to growers. Male sterile plants can sometimes (e.g. in corn) be produced by detasseling, (i.e. the mechanical removal of the male reproductive organs or male flowers) but, more typically, male sterility is the result of genetic determinants in the plant genome. In that case, and especially when seed is the desired product to be harvested from the hybrid plants, it is typically useful to ensure that male fertility in the hybrid plants, which contain the genetic determinants responsible for male sterility, is fully restored. This can be accomplished by ensuring that the male parents have appropriate fertility restorer genes which are capable of restoring the male fertility in hybrid plants that contain the genetic determinants responsible for male sterility. Genetic determinants for male sterility may be located in the cytoplasm. Examples of cytoplasmic male sterility (CMS) were for instance described in Brassica species. However, genetic determinants for male sterility can also be located in the nuclear genome. Male sterile plants can also be obtained by plant biotechnology methods such as genetic engineering. A particularly useful means of obtaining male sterile plants is described in WO 89/10396 in which, for example, a ribonuclease such as a barnase is selectively expressed in the tapetum cells in the stamens. Fertility can then be restored by expression in the tapetum cells of a ribonuclease inhibitor such as barstar.
Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may be treated according to the invention are herbicide-tolerant plants, i.e. plants made tolerant to one or more given herbicides. Such plants can be obtained either by genetic transformation, or by selection of plants containing a mutation imparting such herbicide tolerance. Herbicide-tolerant plants are for example glyphosate-tolerant plants, i.e. plants made tolerant to the herbicide glyphosate or salts thereof. For example, glyphosate-tolerant plants can be obtained by transforming the plant with a gene encoding the enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS). Examples of such EPSPS genes are the AroA gene (mutant CT7) of the bacterium Salmonella typhimurium, the CP4 gene of the bacterium Agrobacterium sp., the genes encoding a petunia EPSPS, a tomato EPSPS, or an Eleusine EPSPS. It can also be a mutated EPSPS. Glyphosate-tolerant plants can also be obtained by expressing a gene that encodes a glyphosate oxidoreductase enzyme. Glyphosate-tolerant plants can also be obtained by expressing a gene that encodes a glyphosate acetyl transferase enzyme. Glyphosate-tolerant plants can also be obtained by selecting plants containing naturally-occurring mutations of the above-mentioned genes.
Other herbicide-resistant plants are for example plants that are made tolerant to herbicides inhibiting the enzyme glutamine synthase, such as bialaphos, phosphinothricin or glufosinate. Such plants can be obtained by expressing an enzyme detoxifying the herbicide or a mutant glutamine synthase enzyme that is resistant to inhibition. One such efficient detoxifying enzyme is, for example, an enzyme encoding a phosphinothricin acetyltransferase (such as the bar or pat protein from Streptomyces species). Plants expressing an exogenous phosphinothricin acetyltransferase have been described.
Further herbicide-tolerant plants are also plants that are made tolerant to the herbicides inhibiting the enzyme hydroxyphenylpyruvatedioxygenase (HPPD). Hydroxyphenylpyruvatedioxygenases are enzymes that catalyse the reaction in which para-hydroxyphenylpyruvate (HPP) is transformed into homogentisate. Plants tolerant to HPPD-inhibitors can be transformed with a gene encoding a naturally-occurring resistant HPPD enzyme, or a gene encoding a mutated HPPD enzyme. Tolerance to HPPD-inhibitors can also be obtained by transforming plants with genes encoding certain enzymes enabling the formation of homogentisate despite the inhibition of the native HPPD enzyme by the HPPD-inhibitor. Tolerance of plants to HPPD inhibitors can also be improved by transforming plants with a gene encoding an enzyme prephenate dehydrogenase in addition to a gene encoding an HPPD-tolerant enzyme.
Still further herbicide-resistant plants are plants that are made tolerant to acetolactate synthase (ALS) inhibitors. Known ALS-inhibitors include, for example, sulphonylurea, imidazolinone, triazolopyrimidines, pyrimidinyloxy(thio)benzoates, and/or sulphonylaminocarbonyltriazolinone herbicides. Different mutations in the ALS enzyme (also known as acetohydroxyacid synthase, AHAS) are known to confer tolerance to different herbicides and groups of herbicides. The production of sulphonylurea-tolerant plants and imidazolinone-tolerant plants has been described in the international publication WO 1996/033270. Further sulphonylurea- and imidazolinone-tolerant plants have also been described, for example in WO 2007/024782.
Other plants tolerant to imidazolinone and/or sulphonylurea can be obtained by induced mutagenesis, by selection in cell cultures in the presence of the herbicide or by mutation breeding.
Plants or plant cultivars (obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are insect-resistant transgenic plants, i.e. plants made resistant to attack by certain target insects. Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such insect resistance.
In the present context, the term “insect-resistant transgenic plant” includes any plant containing at least one transgene comprising a coding sequence encoding:
Of course, insect-resistant transgenic plants, as used herein, also include any plant comprising a combination of genes encoding the proteins of any one of the above classes 1 to 8. In one embodiment, an insect-resistant plant contains more than one transgene encoding a protein of any one of the above classes 1 to 8, to expand the range of target insect species affected or to delay insect resistance development to the plants, by using different proteins insecticidal to the same target insect species but having a different mode of action, such as binding to different receptor binding sites in the insect.

Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such stress resistance. Particularly useful stress tolerance plants include:

Such plants can be obtained by genetic transformation, or by selection of plants containing a mutation imparting such altered fibre characteristics and include:
Plants or plant cultivars (that can be obtained by plant biotechnology methods such as genetic engineering) which may also be treated according to the invention are plants, such as oilseed rape or related Brassica plants, with altered oil profile characteristics.

Industrial materials are understood as meaning, in the present context, non-live materials such as, preferably, polymers, adhesives, glues, paper and board, leather, timber, derived timber products and paints.
The material to be protected from infestation with insects is very especially preferably timber and derived timber products.
Timber and derived timber products which can be protected by the active compound according to the invention or mixtures containing them are to be understood as meaning by way of example:
structural timber, wooden beams, railway sleepers, components of bridges, jetties, vehicles made of wood, boxes, pallets, containers, telegraph poles, wooden lagging, windows and doors made of wood, plywood, chipboard, joinery or wooden products which are used, quite generally, for building houses or in building joinery.
The active compounds can be used as such, in the form of concentrates or generally customary formulations such as powder, granules, solutions, suspensions, emulsions or pastes.
The formulations mentioned can be prepared in a manner known per se, for example by mixing the active compounds with at least one solvent, diluent, emulsifier, dispersant and/or binder or fixative, water repellent, optionally desiccants and UV stabilizers and, if appropriate, colorants and pigments as well as further processing aids.
The insecticidal compositions or concentrates which are used for the protection of timber and derived timber products comprise the active compound according to the invention in a concentration of from 0.0001 to 95% by weight, in particular from 0.001 to 60% by weight.
The amount of the compositions or concentrates employed depends on the species and the abundance of the insects and on the medium. Upon use, the optimal application rate can be determined in each case by a test series. However, in general it will suffice to employ from 0.0001 to 20% by weight, preferably from 0.001 to 10% by weight, of the active compound, based on the material to be protected.
A suitable solvent and/or diluent is an organochemical solvent or solvent mixture and/or an oily or oil-type organochemical solvent or solvent mixture of low volatility and/or a polar organochemical solvent or solvent mixture and/or water and, if appropriate, an emulsifier and/or wetting agent.
Organochemical solvents which are preferably employed are oily or oil-type solvents with an evaporation number of above 35 and a flashpoint of above 30° C., preferably above 45° C. Such oily and oil-type solvents which are insoluble in water and of low volatility and which are used are suitable mineral oils or their aromatic fractions or mineral-oil-containing solvent mixtures, preferably white spirit, petroleum and/or alkylbenzene.
Mineral oils with a boiling range of 170 to 220° C., white spirit with a boiling range of 170 to 220° C., spindle oil with a boiling range of 250 to 350° C., petroleum and aromatics with a boiling range of 160 to 280° C., oil of turpentine, and the like are advantageously used.
In a preferred embodiment, liquid aliphatic hydrocarbons with a boiling range of 180 to 210° C. or high-boiling mixtures of aromatic and aliphatic hydrocarbons with a boiling range of 180 to 220° C. and/or spindle oil and/or monochloronaphthalene, preferably α-monochloronaphthalene, are used.
The organic oily or oil-type solvents of low volatility and with an evaporation number of above 35 and a flashpoint of above 30° C., preferably above 45° C., can be replaced in part by organochemical solvents of high or medium volatility, with the proviso that the solvent mixture also has an evaporation number of above 35 and a flashpoint of above 30° C., preferably above 45° C., and that the mixture is soluble or emulsifiable in this solvent mixture.
In a preferred embodiment, some of the organochemical solvent or solvent mixture is replaced by an aliphatic polar organochemical solvent or solvent mixture. Aliphatic organochemical solvents which contain hydroxyl and/or ester and/or ether groups are preferably used, such as, for example, glycol ethers, esters or the like.
Organochemical binders used for the purposes of the present invention are the synthetic resins and/or binding drying oils which are known per se and which can be diluted in water and/or dissolved or dispersed or emulsified in the organochemical solvents employed, in particular binders composed of, or comprising, an acrylate resin, a vinyl resin, for example polyvinyl acetate, polyester resin, polycondensation or polyaddition resin, polyurethane resin, alkyd resin or modified alkyd resin, phenol resin, hydrocarbon resin such as indene/coumarone resin, silicone resin, drying vegetable oils and/or drying oils and/or physically drying binders based on a natural and/or synthetic resin.
The synthetic resin employed as binder can be employed in the form of an emulsion, dispersion or solution. Bitumen or bituminous substances may also be used as binders, in amounts of up to 10% by weight. In addition, colorants, pigments, water repellents, odour-masking agents, and inhibitors or anticorrosive agents and the like, all of which are known per se, can be employed.
In accordance with the invention, the material or the concentrate preferably comprises, as organochemical binders, at least one alkyd resin or modified alkyd resin and/or a drying vegetable oil. Alkyd resins which are preferably used in accordance with the invention are those with an oil content of over 45% by weight, preferably 50 to 68% by weight.
Some or all of the abovementioned binder can be replaced by a fixative (mixture) or plasticizer (mixture). These additives are intended to prevent volatilization of the active compounds, and also crystallization or precipitation. They preferably replace 0.01 to 30% of the binder (based on 100% of binder employed).
The plasticizers are from the chemical classes of the phthalic esters, such as dibutyl phthalate, dioctyl phthalate or benzyl butyl phthalate, phosphoric esters such as tributyl phosphate, adipic esters such as di(2-ethylhexyl)adipate, stearates such as butyl stearate or amyl stearate, oleates such as butyl oleate, glycerol ethers or higher-molecular-weight glycol ethers, glycerol esters and p-toluenesulphonic esters.
Fixatives are based chemically on polyvinyl alkyl ethers such as, for example, polyvinyl methyl ether, or ketones such as benzophenone and ethylenebenzophenone.
Other suitable solvents or diluents are, in particular, water, if appropriate as a mixture with one or more of the abovementioned organochemical solvents or diluents, emulsifiers and dispersants.
Particularly effective timber protection is achieved by industrial-scale impregnating processes, for example the vacuum, double-vacuum or pressure processes.
The ready-to-use materials may, if appropriate, comprise further insecticides and, if appropriate, also one or more fungicides.

However, the use of the active compounds/active compound combinations according to the invention is in no way restricted to these genera, but extends in the same manner to other plants.
Depending on the concentration, the active compounds/active compound combinations according to the invention are suitable for the nonselective weed control on, for example, industrial terrains and railway tracks and on paths and locations with and without trees. Likewise the active compounds according to the invention can be employed for controlling weeds in perennial crops, for example forests, ornamental tree plantings, orchards, vineyards, citrus groves, nut orchards, banana plantations, coffee plantations, tea plantations, rubber plantations, oil palm plantations, cocoa plantations, soft fruit plantations and hop fields, on lawns, turf and pastureland, and for the selective control of weeds in annual crops.
The compounds of the formula (I)/active compound combinations according to the invention have strong herbicidal activity and a broad activity spectrum when used on the soil and on aerial plant parts. To a certain extent, they are also suitable for the selective control of monocotyledonous and dicotyledonous weeds in monocotyledonous and dicotyledonous crops, both pre- and post-emergence.
At certain concentrations or application rates, the active compounds/active compound combinations according to the invention can also be employed for controlling animal pests and fungal or bacterial plant diseases. If appropriate, they can also be used as intermediates or precursors for the synthesis of other active compounds.
The active compounds/active compound combinations can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusting agents, pastes, soluble powders, granules, suspoemulsion concentrates, natural and synthetic materials impregnated with active compound, and very fine capsules in polymeric substances.
These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surfactants, that is emulsifiers and/or dispersants and/or foam-formers.
If the extender used is water, it is also possible to use, for example, organic solvents as auxiliary solvents. Suitable liquid solvents are essentially: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol, and also their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, and also water.
Suitable solid carriers are: for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as finely divided silica, alumina and silicates, suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, and also synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; suitable emulsifiers and/or foam-formers are: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates and protein hydrolysates; suitable dispersants are: for example lignosulphite waste liquors and methylcellulose.
Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, and also natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Other possible additives are mineral and vegetable oils.
It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian blue, and organic colorants, such as alizarin colorants, azo colorants and metal phthalocyanine colorants, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.
The formulations generally comprise between 0.1 and 95 percent by weight of active compound, preferably between 0.5 and 90%.
The active compounds/active compound combinations according to the invention, as such or in their formulations, can also be used for weed control purposes as a mixture with known herbicides and/or with substances which improve crop plant tolerance (“safeners”), ready mixes or tank mixes being possible. Mixtures with herbicide products which contain one or more known herbicides and a safener are hence also possible.
A mixture with other known active compounds, such as fungicides, insecticides, acaricides, nematicides, bird repellents, plant nutrients and soil conditioners, is also possible.
The active compounds/active compound combinations can be applied as such, in the form of their formulations or the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. They are applied in the customary manner, for example by pouring, spraying, atomizing, spreading.
The active compounds/active compound combinations according to the invention can be applied both before and after plant emergence. They can also be incorporated into the soil prior to sowing.
The application rate of active compound can vary within a substantial range. Essentially, it depends on the nature of the desired effect. In general, the application rates are between 1 g and 10 kg of active compound per hectare of soil area, preferably between 5 g and 5 kg per ha.
The advantageous effect of the compatibility with crop plants of the active compound combinations according to the invention is particularly pronounced at certain concentration ratios. However, the weight ratios of the active compounds in the active compound combinations can be varied within relatively wide ranges. In general, from 0.001 to 1000 parts by weight, preferably from 0.01 to 100 parts by weight, particularly preferably 0.05 to 20 parts by weight, of one of the compounds which improves crop plant compatibility (antidotes/safeners) mentioned above under (b) are present per part by weight of active compound of the formula (I).
The active compound combinations according to the invention are generally applied in the form of finished formulations. However, the active compounds contained in the active compound combinations can, as individual formulations, also be mixed during use, i.e. be applied in the form of tank mixes.
For certain application purposes, in particular by the post-emergence method, it may furthermore be advantageous to include, as further additives in the formulations, mineral or vegetable oils which are compatible with plants (for example the commercial preparation “Rako Binol”), or ammonium salts, such as, for example, ammonium sulphate or ammonium thiocyanate.
The novel active compound combinations can be used as such, in the form of their formulations or the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. Application is in the customary manner, for example by watering, spraying, atomizing, dusting or scattering.
The application rates of the active compound combinations according to the invention can be varied within a certain range; they depend, inter alia, on the weather and on soil factors. In general, the application rates are between 0.001 and 5 kg per ha, preferably between 0.005 and 2 kg per ha, particularly preferably between 0.01 and 0.5 kg per ha.
The active compound combinations according to the invention can be applied before and after emergence of the plants, that is to say by the pre-emergence and post-emergence method.
Depending on their properties, the safeners to be used according to the invention can be used for pretreating the seed of the crop plant (seed dressing) or can be introduced into the seed furrows prior to sowing or be used separately prior to the herbicide or together with the herbicide, before or after emergence of the plants.
In each case, the term “active compounds” or “compounds” also includes the active compound combinations mentioned here.
The preparation and use of the active compounds/active compound combinations according to the invention is illustrated by the examples below.

To prepare a suspension concentrate, initially all liquid components are mixed with one another. In the next step, the solids are added and the mixture is stirred until a homogeneous suspension is formed. The homogeneous suspension is subjected initially to coarse grinding and then to fine grinding, such that a suspension is obtained in which 90% of the solids particles have a particle size of below 10 μm. At room temperature, Kelzan® S and water are then added with stirring until the intended viscosity is reached. This gives a homogeneous suspension concentrate.

Boosting of penetration into the plant by ammonium salts or phosphonium salts, and synergistic boosting of penetration into the plant by ammonium/phosphonium salts in combination with penetration promoters
This test measured the penetration of active compounds through enzymatically isolated cuticles of apple leaves.
The leaves used were cut in the fully developed state from apple trees of the Golden Delicious variety. The cuticles were isolated as follows:
After that, only those cuticles from the top leaf sides that were free from stomata and hairs were used further. They were washed a number of times in alternation with water and with a buffer solution, pH 7. The clean cuticles obtained were, finally, applied to Teflon plaques, smoothed with a gentle jet of air, and dried.
In the next step the cuticular membranes obtained in this way were placed in stainless steel diffusion cells (transport chambers) for the purpose of membrane transport investigations. For these investigations the cuticles were placed centrally using tweezers on the edges of the diffusion cells, which were coated with silicone grease, and sealed with a ring, which was likewise greased. The arrangement had been chosen so that the morphological outer side of the cuticles was directed outwards, in other words facing the air, while the original inner side was facing the inside of the diffusion cell.
The diffusion cells were filled with a 30% strength ethylene glycol/water solution. Penetration was determined by applying 10 μl of the spray liquor of the composition below to the outer side of each of the cuticles. The spray liquor is prepared using local mains water of medium hardness.
After the spray liquors had been applied, the water was evaporated and then the chambers were inverted and placed in thermostated troughs, in which the temperature and humidity over the cuticles was adjustable by means of a gentle stream of air onto the cuticles, with the spray coating (20° C., 60% rh). At regular intervals, samples were taken using an autosampler, and the amount of active compound was determined using HPLC.
The results of the experiment are apparent from the table below. The numbers stated represent average values from 8 to 10 measurements.
To produce a suitable solution of the preparation, the formulation is diluted with water to the desired concentration. If the addition of ammonium salts and penetrant is required, the appropriate amount is pipetted in after dilution of the respective finished solution of the preparation.
