Table Examples of the Compounds of the Formula (IId)
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.
Table Examples of the Compounds of the Formula (IIe)
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 mefenpyrdiethyl.
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 selective herbicidal combinations according to the invention comprising in each case one active compound of the formula (I) and one of the safeners defined above are listed in the table below.
It has now surprisingly been found that the above-defined active-compound combinations of iodophenyl-substituted cyclic ketoenols of the general formula (I) 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 beans, potatoes, corn 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 ketoenols 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 corn and rice, as crop plants.

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 harvest 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, sugar beet, tomatoes, peas and other vegetable varieties, 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), CryIIA, CryIIIA, CryIIIB2, Cry9c Cry2Ab, Cry3Bb and CryIF and their combinations (hereinbelow “Bt plants”). Other traits which are particularly emphasized are the increased defense of plants against fungi, bacteria and viruses by the systemic acquired resistance (SAR), systemins, 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, sulfonylureas, 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), Boligard® (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, soybeans), Liberty Link® (tolerance to phosphinotricin, for example oilseed rape), IMI® (tolerance to imidazolinones) and STS® (tolerance to sulfonylureas, 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.

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 flash point 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 turpentine and the like.

The organic oily or oil-type solvents of low volatility having an evaporation number of above 35 and a flash point 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 flash point 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, odor-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-toluenesulfonic 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.

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.

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 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, alkylsulfonates, alkyl sulfates, arylsulfonates and protein hydrolyzates; suitable dispersants are: for example lignosulfite 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 per cent 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.

A mixture with other known active compounds, such as fungicides, insectides, 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 planting.
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.

For certain applications, 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 sulfate 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.

Herbicidal Pre-Emergence Action
Seeds of monocotyledonous and dicotyledonous weed and crop plants are placed in sandy loam in wood fiber pots and covered with soil. The test compounds, formulated in the form of wettable powders (WP) or as emulsion concentrates (EC), are then, as an aqueous suspension with a water application rate of 800 l/ha (converted), with 0.2% of wetting agent added, applied to the surface of the covering soil.
After the treatment, the pots are placed in a greenhouse and kept under growth conditions for the test plants. The visual assessment of the emergence damage on the test plants is carried out after a trial period of 3 weeks by comparison with untreated controls (herbicidal effect in percent (%): 100% effect=the plants have died, 0% effect=like control plants).
Here, the following compounds, for example, controlled Avena sativa, Lolium multiflorum and Setaria viridis at an application rate of 320 g/ha with ≧70% efficacy:
I-1-a-8, I-1-a-14, I-1-a-21, I-1-a-7.
Herbicidal Post-Emergence Action
Seeds of monocotyledonous and dicotyledonous weed and crop plants are placed in sandy loam in wood fiber pots, covered with soil and cultivated in a greenhouse under good growth conditions. Two to three weeks after sowing, the test plants are treated at the one-leaf stage. The test compounds, formulated as wettable powders (WP) or as emulsion concentrates (EC), are then, as an aqueous suspension with a water application rate of 800 l/ha (converted), with 0.2% of wetting agent added, sprayed onto the green parts of the plants. After the test plants have been kept in the greenhouse under optimum growth conditions for about 3 weeks, the effect of the preparations is rated visually in comparison to treated controls (herbicidal effect in percent (%): 100% effect=the plants have died, 0% effect=like control plants).
Here, the following compounds, for example, controlled Avena sativa, Echinochloa crus-galli, Lolium multiflorum and Setaria viridis at an application rate of 320 g/ha with ≧70% efficacy:
I-1-a-8, I-1-a-11, I-1-a-12, I-1-a-13, I-1-a-14, I-1-a-21, I-1-c-1, I-1-c-6, I-1-c-11, I-1-c-12, I-2-b-10, I-2-c-3, I-8-b-2.
Herbicidal Post-Emergence Action
Seeds of monocotyledonous and dicotyledonous weed and crop plants are placed into sandy loam in wood fiber pots or in plastic pots, covered with soil and cultivated in a greenhouse, during the vegetation period also outdoors outside of the greenhouse, under good growth conditions. Two to three weeks after sowing, the test plants are treated at the one- to three-leaf stage. The test compounds, formulated as wettable powders (WP) or liquid (EC), are, in various dosages at a water application rate of 300 l/ha (converted), with wetting agent (0.2 to 0.3%) added, sprayed onto the plants and the surface of the soil. Three to four weeks after the treatment of the test plants, the effect of the preparations is rated visually in comparison to treated controls (herbicidal effect in %) (%): 100% effect=the plants have died, 0% effect=like control plants).
Use of Safeners
If it is additionally to be tested as to whether safeners can improve the plant compatibility of test substances in the case of crop plants, the following options are used for applying the safener:
By comparing the effect of test substances on crop plants without or with safener treatment, it is possible to assess the effect of the safener substance.

Critical Concentration Test/Soil Insects—Treatment of Transgenic Plants
Test insect: Diabrotica balteata—larvae in the soil
Solvent: 7 parts by weight of acetone
Emulsifier: 1 part by weight of alkylaryl polyglycol ether
To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent, the stated amount of emulsifier is added and the concentrate is diluted with water to the desired concentration.
The preparation of active compound is poured onto the soil. Here, the concentration of active compound in the preparation is virtually immaterial; only the amount by weight of active compound per unit volume of soil, which is stated in ppm (mg/l), matters. The soil is filled into 0.25 l pots, and these are allowed to stand at 20° C.
Immediately after the preparation, 5 pregerminated corn grains of the cultivar YIELD GUARD (trademark of Monsanto Comp., USA) are placed into each pot. After 2 days, the appropriate test insects are placed into the treated soil. After a further 7 days, the efficacy of the active compound is determined by counting the corn plants that have emerged (1 plant=20% activity).
Heliothis virescens Test—Treatment of Transgenic Plants
Solvent: 7 parts by weight of acetone
Emulsifier: 1 part by weight of alkylaryl polyglycol ether
To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent and the stated amount of emulsifier, and the concentrate is diluted with water to the desired concentration.
Soybean shoots (Glycine max) of the cultivar Roundup Ready (trademark of Monsanto Comp. USA) are treated by being dipped into the preparation of active compound of the desired concentration and are populated with the tobacco budworm Heliothis virescens while the leaves are still moist.
After the desired period of time, the kill of the insects is determined.
