20080026943
The present invention relates to new phenyl-substituted [1,2]-oxazine-3,5-dione derivatives and dihydropyrone derivatives, to a number of processes for preparing them and to their use as microbicides and/or pesticides and/or herbicides.
The invention also relates to new selective-herbicidal active-compound combinations which comprise firstly phenyl-substituted [1,2]-oxazine-3,5-dione derivatives or phenyl-substituted dihydropyrone derivatives and secondly at least one crop plant tolerance promoter compound and can be used with particular success for selective weed control in various crops of useful plants.
Not only 4-halo-4-phenyl- and 4-nitro-4-phenyl-substituted [1,2]-oxazine-3,5-dione derivatives but also 3-halo-3-phenyl- and 3-nitro-3-phenyl-substituted dihydropyrone derivatives are unknown to date in the literature. Only 3-halo-3-phenyl-quinoline-2,4-dione derivatives have been described, for example by Kafku, S. et al. in Heterocycles 57, 1659-1682, (2002).
Additionally, 3-nitro-3-phenyl-quinoline-2,4-dione derivatives are known, for example from Stadlbauer, W. et al. from J. Heterocyclic Chemistry 29, 1535-1540, (1992).
A crop protection application for these compounds has not been described.
New compounds of the formula (I) have now been found
in which
The compounds of the formula (I), as they are and as a function of the nature of the substituents, may be present in the form of geometric and/or optical isomers or isomer mixtures, in different compositions, which optionally can be conventionally separated. Not only the pure isomers but also the isomer mixtures, their preparation and use, and also compositions comprising them, are provided by the present invention. Below, however, for the sake of simplicity, explicit reference is always to compounds of the formula (I), although this means not only the pure compounds but also, where appropriate, mixtures with different fractions of isomeric compounds.
The compounds of the formula (I) may be present both as mixtures and in the form of their pure isomers. Mixtures of compounds of the formula (I) can be separated optionally in conventional manner by physical methods, such as by chromatographic methods, for example.
Below, in order not to complicate things unnecessarily, in each case only one of the possible isomers is shown. It is not intended to rule out the possibility of the compounds, where appropriate, being in the form of the isomer mixtures or in the respective other isomeric form.
Including U and V for the groups
and
results in the following primary structures (I-1) and (I-2)
in which
Some of the compounds required for processes A and B, of the formulae (II-1) to (II-2)
Suitable halogenating agents for process A include, for example, sulphuryl chloride, sulphuryl bromide, thionyl chloride, thionyl bromide, imides, such as N-bromosuccinimide or N-chlorosuccinimide, chlorosulphonic acid, and also hypochlorites, such as tert-butyl hypochlorite, for example.
Suitable nitrating reagents for process B include fuming nitric acid, and also “nitrating acid mixtures”.
Additionally it has been found that the new compounds of the formula (I) exhibit very good activity as pesticides, preferably as insecticides and/or acaricides and/or microbicides and/or as herbicides.
Surprisingly it has now also been found that certain substituted, cyclic keto enols, when employed together with the crop plant tolerance promoter compounds (safeners/antidotes) described later on, are extremely good at preventing damage to the crop plants and can be used with particular advantage as broad-spectrum combination products for the selective control of unwanted plants in crops of useful plants, such as in cereals but also in maize, soya and rice, for example.
The invention also provides selective-herbicidal compositions comprising an effective amount of an active-compound combination comprising as components
The formulae (I-1) and/or (I-2) provide a general definition of the compounds according to the invention. Preferred substituents or ranges of the radicals listed in the formulae given above and below are elucidated below:
In the radical definitions mentioned as being preferred, halogen, including halogen as a substituent, such as in haloalkyl, for example, represents fluorine, chlorine, bromine and iodine, especially represents fluorine and chlorine.
In the radical definitions mentioned as being particularly preferred, halogen, both alone and as a substituent, such as in haloalkyl, for example, represents fluorine, chlorine, bromine and iodine, particularly represents fluorine and chlorine, and especially represents fluorine.
W with very particular preference represents hydrogen, fluorine, chlorine, bromine, methyl, ethyl, n-propyl or methoxy,
The general radical definitions and/or elucidations set out above, or those set out in ranges of preference, can be combined with one another arbitrarily, i.e. including combinations between the respective ranges and ranges of preference. They apply to the end products and also to the precursors and intermediates accordingly.
Preference in accordance with the invention is given to the compounds of the formula (I) in which there is a combination of the definitions set out above as being preferred (preferable).
Particular preference in accordance with the invention is given to the compounds of the formula (I) in which there is a combination of the definitions set out above as being particularly preferred.
Very particular preference in accordance with the invention is given to the compounds of the formula (I) in which there is a combination of the definitions set out above as being very particularly preferred.
Most preferred in accordance with the invention are the compounds of the formula (I) in which there is a combination of the definitions set out above as being most preferred.
Saturated or unsaturated hydrocarbon radicals such as alkyl or alkenyl, both alone and in conjunction with heteroatoms, such as in alkoxy, for example, can as far as possible be straight-chain or branched in each case.
Optionally substituted radicals can be substituted one or more times unless indicated otherwise, and in the case of multiple substitutions the substituents can be identical or different.
Preferred definitions of the groups listed above in connection with the crop plant tolerance promoter 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 Table 1 below.
Examples of the compounds of the formula (IIb) which are very particularly preferred as herbicide safeners according to the invention are listed in Table 2 below.
Examples of the compounds of the formula (IIc) which are very particularly preferred as herbicide safeners according to the invention are listed in Table 3 below.
Examples of the compounds of the formula (IId) which are very particularly preferred as herbicide safeners according to the invention are listed in Table 4 below.
Examples of the compounds of the formula (IIe) which are very particularly preferred as herbicide safeners according to the invention are listed in Table 5 below.
Most preferred as crop plant tolerance promoter 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-99/667951U.S. Pat. No. 6,251,827).
Examples of the selective-herbicidal combinations according to the invention comprising in each case one active compound of the formula (I-1) or (I-2) and one of the safeners defined above are listed in Table 6 below.
It has now surprisingly been found that the above-defined active-compound combinations of phenyl-substituted [1,2]-dioxazine derivatives of the formula (I-1) or phenyl-substituted dihydropyrone derivatives of the formula (I-2) and safeners (antidotes) from the group (b′) set out above combine very good useful plant tolerance with a 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 selective weed control.
In this context it is 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 substituted cyclic keto enols 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′), particularly 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.
Using, for example, according to process (A), 4-(2-methyl-5-bromo)phenyl-2,6,6-trimethyloxazine-3,5-dione or its enol as starting material, the course of the process of the invention can be represented by the following reaction scheme:
Using, for example, according to process (B), 3-[2-methyl-5-(4-chlorophenyl)phenyl]-5,5,6,6-tetramethyl-5,6-dihydropyrone-2,4-dione or its enol, the course of the process of the invention can be represented by the following reaction scheme:

When carrying out process (B) of the invention the reaction components of the formula (II) and the nitrating reagent are generally used in approximately equimolar amounts. It is, however, also possible to use one or the other component in a relatively large excess (up to 5 mol).
Purification takes place after customary workup by crystallization or chromatographic purification on silica gel.

All plants and plant parts can be treated in accordance with the invention. Plants are to be understood as meaning in the present context 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 plant breeding and optimization methods or by biotechnological and recombinant methods or by combinations of these methods, including the transgenic plants and inclusive of the plant cultivars protectable or not protectable by plant breeders' rights. Plant parts are to be understood as meaning all parts and organs of plants above and below the ground, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stalks, stems, flowers, fruit bodies, fruits, seeds, roots, tubers and rhizomes. The plant parts also include harvested material, and vegetative and generative propagation material, for example cuttings, tubers, rhizomes, offsets and seeds.
The treatment according to the invention of the plants and plant parts with the active compounds is carried out directly or by allowing the compounds to act on their surroundings, habitat or storage space by the customary treatment methods, for example by immersion, spraying, evaporation, fogging, scattering, painting on, injecting and, in the case of propagation material, in particular in the case of seeds, also by applying one or more coats.
The active compounds can be converted into the customary formulations such as solutions, emulsions, wettable powders, suspensions, powders, dusts, pastes, soluble powders, granules, suspension-emulsion concentrates, natural and synthetic materials impregnated with active compound, and microencapsulations in polymeric materials.
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, 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 and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, or else natural phospholipids such as cephalins and lecithins and synthetic phospholipids can be used in the formulations. Other additives can be 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% by weight of active compound, preferably between 0.5 and 90%.
The active compounds according to the invention, as such or in their formulations, can also be used as a mixture with known fungicides, bactericides, acaricides, nematicides or insecticides, for example in order to widen the spectrum of action or to prevent the development of resistances in this way. In many cases, synergistic effects result, i.e. the activity of the mixture exceeds the activity of the individual components.

Insecticides/acaricides/nematicides
A mixture with other known active compounds, such as herbicides, or with fertilizers and growth regulators, safeners and/or semiochemicals is also possible.
When used as insecticides in their commercially available formulations and in the use forms prepared with these formulations, the active compounds according to the invention can furthermore be present in the form of a mixture with synergists. Synergists are compounds by which the activity of the active compounds is increased without it being necessary for the synergist added to be active itself.
When used as insecticides in their commercially available formulations and in the use forms prepared with these formulations, the active compounds according to the invention can furthermore be present in the form of a mixture with inhibitors which reduce the degradation of the active compound after application in the habitat 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 broad ranges. The active compound concentration of the use forms can be from 0.0000001 up to 95% by weight of active compound, preferably between 0.0001 and 1% by weight.
They are applied in a customary manner adapted to suit the use forms.
When used against hygiene pests and pests of stored products, the active compound is distinguished by excellent residual action on wood and clay as well as good stability to alkali on limed substrates.
As already mentioned above, it is possible to treat all plants and their parts in accordance with the invention. In a preferred embodiment, wild plant species or plant varieties and plant cultivars which have been obtained by traditional biological breeding methods, such as hybridization or protoplast fusion, and the parts of these varieties and cultivars are treated. In a further preferred embodiment, transgenic plants and plant cultivars which have been obtained by recombinant methods, if appropriate in combination with conventional methods (genetically modified organisms), and their parts are treated. The term “parts” or “parts of plants” or “plant parts” has been explained above.
Plants which are treated particularly preferably in accordance with the invention are those of the plant cultivars which are in each case commercially available or in use. Plant cultivars are understood as meaning plants with new traits which have been bred either by conventional breeding, by mutagenesis or by recombinant DNA techniques. They may take the form of cultivars, biotypes and genotypes.
Depending on the plant species or plant cultivars, their location and growth conditions (soils, climate, vegetation period, nutrition), the treatment according to the invention may also result in superadditive (“synergistic”) effects. Thus, for example, reduced application rates and/or a widened activity spectrum and/or an increase in the activity of the substances and compositions which can be used in accordance with the invention, better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to salinity in the water or soil, increased flowering performance, facilitated harvesting, accelerated maturation, higher yields, higher quality and/or better nutritional value of the harvested products, better storage characteristics and/or processability of the harvested products are possible which exceed the effects which were actually to be expected.
The preferred transgenic plants or plant cultivars (those obtained by recombinant methods) to be treated in accordance with the invention include all those plants which, owing to the process of recombinant modification, were given genetic material which confers particular, advantageous, valuable traits to these plants. Examples of such properties are better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to salinity in the water or soil, increased flowering performance, facilitated harvesting, accelerated maturation, higher yields, higher quality and/or higher nutritional value of the harvested products, better storage characteristics and/or better processability of the harvested products. Further examples of such traits, examples which must be mentioned especially, are better defense of the plants against animal and microbial pests, such as against insects, mites, phytopathogenic fungi, bacteria and/or viruses and an increased tolerance of the plants to certain herbicidal active compounds. Examples of transgenic plants which may be mentioned are the important crop plants, such as cereals (wheat, rice), maize, soybeans, potato, cotton, tobacco, oilseed rape and fruit plants (with the fruits apples, pears, citrus fruits and grapes), with particular emphasis on maize, soybeans, potatoes, cotton, tobacco, and oilseed rape. Traits which are especially emphasized are the increased defense of the plants against insects, arachnids, nematodes and slugs and snails, owing to toxins being formed in the plants, in particular toxins which are generated in the plants by the genetic material of Bacillus thuringiensis (for example by the genes CryIA(a), CryIA(b), CryIA(c), CrylIA, CryIIIA, CryIIIB2, Cry9c Cry2Ab, Cry3Bb and CryIF and their combinations; hereinbelow “Bt plants”). Other traits which are particularly emphasized are the increased defence of plants against fungi, bacteria and viruses by the systemic acquired resistance (SAR), systemin, phytoalexins, elicitors and resistance genes and correspondingly expressed proteins and toxins. Other traits which are especially emphasized are the increased tolerance of the plants to certain herbicidal active compounds, for example imidazolinones, sulphonylureas, glyphosate or phosphinotricin (for example “PAT” gene). The genes which confer the desired traits in each case may also be present in the transgenic plants in combination with one another. Examples of “Bt plants” which may be mentioned are maize cultivars, cotton cultivars, soybean cultivars and potato cultivars which are commercially available under the trade names YIELD GARD® (for example maize, cotton, soybeans), KnockOut® (for example maize), StarLink® (for example maize), Bollgard® (cotton), Nucotn® (cotton) and NewLeaf® (potato). Examples of herbicide-tolerant plants which may be mentioned are maize cultivars, cotton cultivars and soybean cultivars which are commercially available under the trade names Roundup Ready® (tolerance to glyphosate, for example maize, cotton, soybean), Liberty Link® (tolerance to phosphinotricin, for example oilseed rape), IMI® (tolerance to imidazolinones) and STS® (tolerance to sulphonylureas, for example maize). Herbicide-resistant plants (plants bred in a conventional manner for herbicide tolerance) which may be mentioned also include the varieties commercially available under the name Clearfield® (for example maize). Naturally, these statements also apply to plant cultivars having these genetic traits or genetic traits still to be developed, which plant cultivars will be developed and/or marketed in the future.

Industrial materials are to be understood as meaning, in the present context, non-live materials, such as, preferably, synthetic materials, glues, sizes, paper and board, leather, wood and timber products, and paint.
The materials to be very particularly preferably protected against attack by insects are wood and timber products.
Wood and timber products which can be protected by the composition according to the invention or mixtures comprising such a composition are to be understood as meaning, for example:
construction timber, wooden beams, railway sleepers, bridge components, jetties, wooden vehicles, boxes, pallets, containers, telephone poles, wood cladding, windows and doors made of wood, plywood, particle board, joiner's articles, or wood products which, quite generally, are used in the construction of houses or in joinery.
The active compounds can be used as such, in the form of concentrates or generally customary formulations, such as powders, 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 or diluent, emulsifier, dispersant and/or binder or fixative, water repellent, if appropriate desiccants and UV stabilizers and, if appropriate, colorants and pigments and other processing auxiliaries.
The insecticidal compositions or concentrates used for the protection of wood and wooden materials comprise the active compound according to the invention in a concentration of 0.0001 to 95% by weight, in particular 0.001 to 60% by weight.
The amount of the compositions or concentrates employed depends on the species and the occurrence of the insects and on the medium. The optimum rate of application can be determined upon use in each case by a test series. However, in general, it suffices to employ 0.0001 to 20% by weight, preferably 0.001 to 10% by weight, of the active compound, based on the material to be protected.
The solvent and/or diluent used 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 having an evaporation number of above 35 and a flashpoint of above 30° C., preferably above 45° C. Substances which are used as such oily and oil-type solvents which have low volatility and are insoluble in water are suitable mineral oils or their aromatic fractions, or mineral-oil-containing solvent mixtures, preferably white spirit, petroleum and/or alkylbenzene.
Substances which are advantageously used are 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 or aromatics of boiling range 160 to 280° C., essence of terpentine and the like.

The organic oily or oil-type solvents of low volatility having an evaporation number of above 35 and a flashpoint of above 30° C., preferably above 45° C., can be partially replaced 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 insecticide/fungicide mixture is soluble or emulsifiable in this solvent mixture.
In a preferred embodiment, part of the organochemical solvent or solvent mixture or an aliphatic polar organochemical solvent or solvent mixture is replaced. Substances which are preferably used are aliphatic organochemical solvents having hydroxyl and/or ester and/or ether groups, such as, for example, glycol ethers, esters and the like.
The organochemical binders used within the scope of the present invention are the synthetic resins and/or binding drying oils which are known per se and can be diluted with water and/or are soluble or dispersible or emulsifiable 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/cumarone resin, silicone resin, drying vegetable and/or drying oils and/or physically drying binders based on a natural and/or synthetic resin.
The synthetic resin used as the binder can be employed in the form of an emulsion, dispersion or solution. Up to 10% by weight of bitumen or bituminous substances can also be used as binders. In addition, colorants, pigments, water repellents, odour-masking substances and inhibitors or anticorrosives known per se and the like can also be employed.
The composition or the concentrate preferably comprises, in accordance with the invention, at least one alkyd resin or modified alkyd resin and/or a drying vegetable oil as the organochemical binder. Preferably used according to the invention are alkyd resins with an oil content of over 45% by weight, preferably 50 to 68% by weight.
All or some of the abovementioned binder can be replaced by a fixative (mixture) or a plasticizer (mixture). These additives are intended to prevent volatilization of the active compounds and 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, the phosphoric esters, such as tributyl phosphate, the adipic esters, such as di-(2-ethylhexyl) adipate, the stearates, such as butyl stearate or amyl stearate, the oleates, such as butyl oleate, the glycerol ethers or relatively high-molecular-weight glycol ethers, glycerol esters and p-toluenesulphonic esters.
Fixatives are chemically based on polyvinyl alkyl ethers, such as, for example, polyvinyl methyl ether, or ketones, such as benzophenone or ethylenebenzophenone.
Particularly suitable as a solvent or diluent is also water, if appropriate as a mixture with one or more of the abovementioned organochemical solvents or diluents, emulsifiers and dispersants.
Particularly effective protection of wood is achieved by large-scale industrial impregnation processes, for example vacuum, double-vacuum or pressure processes.
If appropriate, the ready-to-use compositions can additionally comprise other insecticides and, if appropriate, additionally one or more fungicides.

The compounds according to the invention can at the same time be employed for protecting objects which come into contact with salt water or brackish water, in particular hulls, screens, nets, buildings, moorings and signalling systems, against fouling.
Fouling by sessile Oligochaeta, such as Serpulidae, and by shells and species from the Ledamorpha group (goose barnacles), such as various Lepas and Scalpellum species, or by species from the Balanomorpha group (acorn barnacles), such as Balanus or Pollicipes species, increases the frictional drag of ships and, as a consequence, leads to a marked increase in operation costs owing to higher energy consumption and additionally frequent residence in the dry dock.
Apart from fouling by algae, for example Ectocarpus sp. and Ceramium sp., fouling by sessile Entomostraka groups, which come under the generic term Cirripedia (cirriped crustaceans), is of particular importance.
Surprisingly, it has now been found that the compounds according to the invention, alone or in combination with other active compounds, have an outstanding antifouling action.

At certain concentrations or application rates, the active compounds 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 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.

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 active compounds according to the invention also have very good fortifying action in plants. Accordingly, they can be used for mobilizing the defenses of the plant against attack by unwanted microorganisms.
In the present context, plant-fortifying (resistance-inducing) substances are to be understood as meaning those substances which are capable of stimulating the defense system of plants such that, when the treated plants are subsequently inoculated with unwanted microorganisms, they show substantial resistance against these microorganisms.
In the present case, unwanted microorganisms are to be understood as meaning phytopathogenic fungi, bacteria and viruses.

At certain concentrations and application rates, the active compounds according to the invention can if appropriate also be used as herbicides, for influencing plant growth and for controlling animal pests. If appropriate, they can also be used as intermediates and precursors for the synthesis of further active compounds.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents, liquefied gases under pressure, 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 employ, for example, organic solvents as auxiliary solvents. Essentially, suitable liquid solvents are: aromatics such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example petroleum fractions, 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. Liquefied gaseous extenders or carriers are to be understood as meaning liquids which are gaseous at standard temperature and under atmospheric pressure, for example aerosol propellants such as halogenated hydrocarbons, or else butane, propane, nitrogen and carbon dioxide. Suitable solid carriers are: for example 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, 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 and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, or else 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% by weight of active compound, preferably between 0.5 and 90%.
The active compounds according to the invention can be used as such or in their formulations, also in a mixture with known fungicides, bactericides, acaricides, nematicides or insecticides, to broaden, for example, the activity spectrum or to prevent development of resistance. In many cases, synergistic effects are obtained, i.e. the activity of the mixture is greater than the activity of the individual components.
Suitable mixing components are those specified above
A mixture with other known active compounds, such as herbicides, or with fertilizers and growth regulators, is also possible.

Microsporon species such as Microsporon canis and audouinii. The listing of these fungi by no means limits the mycotic spectrum that can be covered, but is only for illustration.
The active compounds can be used as such, in the form of their formulations or the use forms prepared therefrom, such as ready-to-use solutions, suspensions, wettable powders, pastes, soluble powders, dusts and granules. Application is carried out in a customary manner, for example by watering, spraying, atomizing, broadcasting, dusting, foaming, spreading, etc. It is further possible to apply the active compounds by the ultra-low-volume method, or to inject the active compound preparation or the active compound itself into the soil. It is also possible to treat the seeds of the plants.
When using the active compounds according to the invention as fungicides, the application rates can be varied within a relatively wide range, depending on the kind of application. For the treatment of parts of plants, the active compound application rates are generally between 0.1 and 10 000 g/ha, preferably between 10 and 1000 g/ha.

To test for protective activity, young plants are sprayed with the preparation of active compound at the stated application rate. After the spray coating has dried on, the plants are inoculated with an aqueous conidia suspension of the causative organism of apple scab, Venturia inaequalis, and then spend 1 day in an incubation cabin at about 20° C. and 100% relative humidity.
Thereafter the plants are placed in a greenhouse at about 21° C. and about 90% relative humidity.
Evaluation takes place 10 days after inoculation. 0% denotes an efficacy corresponding to that of the control, while an efficacy of 100% denotes a total absence of observed infestation.
Botrytis test (bean)/protective
A suitable preparation of active compound is prepared by mixing 1 part by weight of active compound with the stated amounts of solvent and emulsifier and diluting the concentrate with water to the desired concentration.
To test for protective activity, young plants are sprayed with the preparation of active compound at the stated application rate. After the spray coating has dried on, two small pieces of agar colonized by Botrytis cinerea are placed on each leaf. The inoculated plants are placed in a darkened chamber at about 20° C. and 100% humidity.
Two days after inoculation, the size of the infestation spots on the leaves is evaluated. 0% denotes an efficacy corresponding to that of the control, while an efficacy of 100% denotes a total absence of observed infestation.
Diabrotica balteata - larvae in soil
A suitable preparation of active compound is prepared by mixing 1 part by weight of active compound with the stated amount of solvent, adding the stated amount of emulsifier and diluting the concentrate with water to the desired concentration.
The preparation of active compound is poured onto the soil. The concentration of the active compound in the preparation is almost irrelevant here, the only critical factor being the amount by weight of active compound per unit volume of soil, which is reported in ppm (mg/l). The soil is placed in 0.25 l pots which are left to stand at 20° C.
Immediately after sample preparation, 5 pregerminated maize corns of the cultivar YIELD GUARD (trade mark of Monsanto Comp., USA) are placed in each pot. After 2 days the corresponding test insects are placed into the treated soil. After a further 7 days the efficacy of the active compound is determined by counting the maize plants that have emerged (1 plant=20% effect).
Heliothis virescens test - treatment of transgenic plants
An appropriate preparation of active compound is prepared by mixing 1 part by weight of active compound with the stated amount of solvent and the stated amount of emulsifier and diluting the concentrate with water to the desired concentration.
Soya bean shoots (Glycine max) of the cultivar Roundup Ready (trade mark of Monsanto Comp. USA) are treated by being immersed in the preparation of active compound at the desired concentration and are populated with the tobacco bugworm Heliothis virescens while the leaves are still moist.
After the desired time, the kill of the insects is determined.
