This application is a National Stage of International Application No. PCT/EP2005/007794, filed Jul. 18, 2005, which claims the benefit of German Patent Application No. 10 2004 035 133.3, filed Jul. 20, 2004. The entirety of each of these applications is incorporated by reference herein.
The invention relates to the use of selective insecticidally and/or acaricidally active compound combinations which comprise substituted cyclic ketoenols, on the one hand, and at least one compound which improves crop plant compatibility, on the other, for the selective control of insects and/or spider mites in various crops of useful plants.
Pharmaceutical properties of 3-acylpyrrolidine-2,4-diones have already been described (S. Suzuki et al. Chem. Pharm. Bull. 15 1120 (1967)). Furthermore, N-phenylpyrrolidine-2,4-diones were synthesized by R. Schmierer and H. Mildenberger (Liebigs Ann. Chem. 1985, 1095). A biological activity of these compounds has not been described.
EP-A-0 262 399 and GB-A-2 266 888 disclose compounds of a similar structure (3-arylpyrrolidine-2,4-diones) of which, however, no herbicidal, insecticidal or acaricidal action has been disclosed. Unsubstituted bicyclic 3-arylpyrrolidine-2,4-dione derivatives (EP-A-355 599, EP-A-415 211 and JP 12-053 670) and substituted monocyclic 3-arylpyrrolidine-2,4-dione derivatives (EP-A-377 893 and EP-A-442 077) having herbicidal, insecticidal or acaricidal action have been disclosed.
There have also been disclosed 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 94/01 997, 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 99/16748, WO 99/24437, WO 99/43649, WO 99/48869 und WO 99/55673, WO 01/17972, WO 01/23354, WO 01/74770, WO 03/062244, WO 04/007448, WO 04/024688, WO 04/080962, WO 04/065366, WO 04/111042, DE-A-10351646, DE-A-10354628, DE-A-10354629, DE-A-10351647).
It is known that certain substituted Δ3-dihydrofuran-2-one derivatives have herbicidal properties (cf. DE-A-4 014 420). The synthesis of the tetronic acid derivatives used as starting materials (such as, for example, 3-(2-methylphenyl)-4-hydroxy-5-(4-fluorophenyl)-Δ3-dihydrofuran-2-one) is also described in DE-A-4 014 420. Compounds of a similar structure known from the publication Campbell et al., J. Chem. Soc., Perkin Trans. 1, 1985, (8) 1567-76, but no insecticidal and/or acaricidal activity is mentioned. 3-Aryl-Δ3-dihydrofuranone derivatives having herbicidal, acaricidal and insecticidal properties are also known from EP-A-528 156, EP-A-0 647 637, WO 95/26 345, WO 96/20 196, WO 96/25 395, WO 96/35 664, WO 97/01 535, WO 97/02 243, WO 97/36 868, WO 98/05638, WO 98/25928, WO 99/16748, WO 99/43649, WO 99/48869, WO 99/55673, WO 01/23354, WO 01/74770, WO 03/062244, WO 04/024688 and WO 04/080962. 3-Aryl-Δ3-dihydrothiophenone derivatives are likewise known (WO 95/26 345, 96/25 395, WO 97/01 535, WO 97/02 243, WO 97/36 868, WO 98/05638, WO 98/25928, WO 99/16748, WO 99/43649, WO 99/48869, WO 99/55673, WO 01/17972, WO 01/23354, WO 01/74770, WO 03/062244, WO 04/080962, WO 04/111042).
Certain phenylpyrone derivatives which are unsubstituted in the phenyl ring are already known (cf. A. M. Chirazi, T. Kappe and E. Ziegler, Arch. Pharm. 309, 558 (1976) and K.-H. Boltze and K. Heidenbluth, Chem. Ber. 91, 2849), but a possible use of these compounds as pesticides has not been mentioned. Phenylpyrone derivatives which are substituted in the phenyl ring and have herbicidal, acaricidal and insecticidal properties are described in EP-A-588 137, WO 96/25 395, WO 96/35 664, WO 97/01 535, WO 97/02 243, WO 97/16 436, WO 97/19 941, WO 97/36 868, WO 98/05638, WO 99/43649, WO 99/48869, WO 99/55673, WO 01/17972, WO 01/74770, WO 03/062244, WO 04/080962, WO 04/111042.
Certain 5-phenyl-1,3-thiazine derivatives which are unsubstituted in the phenyl ring are already known (cf. E. Ziegler and E. Steiner, Monatsh. 95, 147 (1964), R. Ketcham, T. Kappe and E. Ziegler, J. Heterocycl. Chem. 10, 223 (1973)), but a possible use of these compounds as pesticides has not been mentioned. 5-Phenyl-1,3-thiazine derivatives which are substituted in the phenyl ring and have herbicidal, acaricidal and insecticidal action are described in WO 94/14 785, WO 96/02 539, WO 96/35 664, WO 97/01 535, WO 97/02 243, WO 97/02 243, WO 97/36 868, WO 99/05638, WO 99/43649, WO 99/48869, WO 99/55673, WO 01/17972, WO 01/74770, WO 03/062244, WO 04/080962, WO 04/111042.
It is known that certain substituted 2-arylcyclopentanediones have herbicidal, insecticidal and acaricidal properties (cf., for example, U.S. Pat. Nos. 4,283,348; 4,338,122; 4,436,666; 4,526,723; 4,551,547; 4,632,698; WO 96/01 798; WO 96/03 366, WO 97/14 667 and also WO 98/39281, WO 99/43649, WO 99/48869, WO 99/55673, WO 01/17972, WO 01/74770, WO 03/062244, WO 04/080962, WO 04/111042). Moreover, compounds having similar substitutions are known; 3-hydroxy-5,5-dimethyl-2-phenylcyclopent-2-en-1-one from the publication Micklefield et al., Tetrahedron, (1992), 7519-26, and the natural product involution (−)-cis-5-(3,4-dihydroxyphenyl)-3,4-dihydroxy-2-(4-hydroxyphenyl)cyclopent-2-en one from the publication Edwards et al., J. Chem. Soc. S, (1967), 405-9. An insecticidal or acaricidal action is not described. Moreover, 2-(2,4,6-tri-methylphenyl)-1,3-indanedione is known from the publication J. Economic Entomology, 66, (1973), 584 and the Offenlegungsschrift (German Published Specification) DE-A 2 361 084, with herbicidal and acaricidal actions being mentioned.
It is known that certain substituted 2-arylcyclohexanediones have herbicidal, insecticidal and acaricidal properties (U.S. Pat. Nos. 4,175,135, 4,209,432, 4,256,657, 4,256,658, 4,256,659, 4,257,858, 4,283,348, 4,303,669, 4,351,666, 4,409,153, 4,436,666, 4,526,723, 4,613,617, 4,659,372, DE-A 2 813 341, and also Wheeler, T. N., J. Org. Chem. 44, 4906 (1979), WO 99/43649, WO 99/48869, WO 99/55673, WO 01/17972, WO 01/74770, WO 03/062244, WO 04/080962, WO 04/111042).
It is known that certain substituted 4-arylpyrazolidine-3,5-diones have acaricidal, insecticidal and herbicidal properties (cf., for example, WO 92/16 510, EP-A-508 126, WO 96/11 574, WO 96/21 652, WO 99/47525, WO 01/17 351, WO 01/17 352, WO 01/17 353, WO 01/17 972, WO 01/17 973, WO 03/028466, WO 03/062244, WO 03/062244, WO 04/080962).
Moreover, selective herbicides based on substituted cyclic ketoenols and safeners have been described (WO 03/013249).
However, the compatibility of these compounds in particular with monocotyledonous crop plants is not under all conditions entirely satisfactory.
Surprisingly, it has now been found that certain substituted cyclic ketoenols, when used together with the crop plant compatibility-improving compounds (safeners/antidotes) described below, prevent damage to the crop plants extremely efficiently and can be used particularly advantageously as broadband combination preparations for the selective control of insects even in crops of monocotyledonous useful plants, such as, for example, in cereals, but also in maize, millet and rice.
The invention provides the use of selective insecticidal and/or acaricidal compositions comprising an effective amount of an active compound combination comprising, as components,

In the definitions, the hydrocarbon chains, such as in alkyl or alkanediyl, are in each case straight-chain or branched—including in combination with heteroatoms, such as in alkoxy.
Depending inter alia on the nature of the substituents, the compounds of the formula (I) can be present as geometrical and/or optical isomers or isomer mixtures of varying composition which, if appropriate, can be separated in a customary manner. The present invention provides both the pure isomers and the isomer mixtures, and their use and the compositions 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, also mixtures having various proportions of isomeric compounds.

Table Examples of the combinations according to the invention
The compounds of the general formula (IIa) to be used as safeners 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 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 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 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 are known and/or can be prepared by processes known per se (cf. WO-A-99/66795/U.S. Pat. No. 6,251,827).
Surprisingly, it has now been found that the above-defined active compound combinations of substituted ketoenols of the general formula (I) and safeners (antidotes) of group (b) listed above, whilst being tolerated very well by useful plants, have good insecticidal and/or acaricidal activity and can be used in various crops, in particular in cereals (especially wheat and barley), but also in millet, maize and rice, for the selective control of insects.
Here, it has to be considered to be surprising that, from a large number of known safeners or antidotes which are capable of antagonizing the damaging effect of a herbicide on the crop plants, it is in particular the abovementioned compounds of group (b) which are suitable for neutralizing the damaging effect of substituted cyclic ketoenols of the formula (I) on the crop plants virtually completely without negatively affecting the insecticidal and/or acaricidal activity.
Furthermore, it has to be considered to be completely surprising that compounds from group (b) listed above are not only capable of virtually completely neutralizing the damaging effect of substituted cyclic ketoenols of the formula (I) on the crop plants but in some cases even enhance the insecticidal and/or acaricidal activity of the substituted cyclic ketoenols of the formula (I), so that a synergistic effect can be observed.
Emphasis is given here to the particularly advantageous effect of the particularly and most preferred combination partners from group (b), in particular in respect of sparing cereal plants, such as, for example, wheat, barley and rye, but also millet, maize and rice, as crop plants.
The combinations of active compounds can be used, for example, for the following plants:
Dicotyledonous crops of the genera: Gossypium, Glycine, Beta, Daucus, Phaseolus, Pisum, Solanum, Linum, Ipomoea, Vicia, Nicotiana, Lycopersicon, Arachis, Brassica, Lactuca, Cucumis, Cuburbita, Helianthus.
Monocotyledonous crops of the genera: Oryza, Zea, Triticum, Hordeum, Avena, Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus, Allium.
However, the use of the combinations of active compounds is by no means limited to these genera but equally also extends to other plants.
The advantageous effect of the combinations of active compounds is particularly strongly pronounced at certain concentration ratios. However, the weight ratios of the active compounds in the combinations of active compounds can be varied within relatively wide ranges. In general, 0.001 to 1000 parts by weight, preferably 0.01 to 100 parts by weight, particularly preferably 0.05 to 10 parts by weight and most preferably 0.07 to 1.5 parts by weight of one of the crop plant compatibility-improving compounds (antidotes/safeners) mentioned above under (b) are present per part by weight of active compound of the formula (I) or salts thereof.
The active compounds or active compound combinations can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusts, pastes, soluble powders, granules, suspoemulsion 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 surface-active agents, 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 mainly: 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 mineral oil fractions, mineral and vegetable oils, alcohols, such as butanol or glycol and ethers and esters thereof, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, and 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 as solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, and synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; suitable as 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 as 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 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 in general comprise between 0.1 and 95% by weight of active compounds, including the active compounds with a safening effect, preferably between 0.5 and 90%.
The combinations of active compounds are generally applied in the form of ready-to-use formulations. However, the active compounds contained in the combinations of active compounds may also be applied in the form of individual formulations which are mixed upon use, that is, in the form of tank mixes.
The combinations of active compounds, as such or in their formulations, may furthermore also be used as a mixture with other known herbicides, again with ready-to-use formulations or tank mixes being possible. A mixture with other known active compounds, such as fungicides, insecticides, acaricides, nematicides, attractants, sterilants, bactericides, bird repellents, growth substances, plant nutrients and soil conditioners is also possible. It may furthermore be advantageous for specific applications, in particular for the post-emergence method, to incorporate into the formulations plant-compatible mineral or vegetable oils (for example the commercial product “Rako Binol”) or ammonium salts, such as, for example, ammonium sulphate or ammonium thiocyanate, as further additives.
The combinations of active compounds can be used as such, in the form of their formulations or the use forms which are prepared from these formulations by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. Application is effected in the customary manner, for example by watering, spraying, atomizing, dusting or broadcasting.
The application rates of the combinations of active compound can be varied within a certain range; they depend inter alia on the weather and on the soil factors. In general, the application rates are between 0.005 and 5 kg per ha, preferably between 0.01 and 2 kg per ha, particularly preferably between 0.05 and 1.0 kg per ha.
The combinations of active compounds can be applied before and after emergence of the plants, i.e. by the pre-emergence and the post-emergence method.
Depending on their properties, the safeners to be used can be employed for pretreating the seed of the crop plant (seed dressing) or be incorporated into the seed furrows before sowing or, together with the herbicide, be applied before or after emergence of the plants.

When used as insecticides, the combinations of active compounds can furthermore be present, in their commercial formulations and in the use forms prepared from these formulations, as a mixture with synergists. Synergists are compounds which enhance the activity of the active compounds, without it being necessary for the added synergist to be active for its part.
The content of active compounds of the use forms prepared from the commercial formulations may vary within wide ranges. The concentration of active compounds of the use forms may be from 0.0000001 to 95% by weight of active compound and is preferably from 0.0001 to 1% by weight.
Application is carried out in a customary manner adapted to the use forms.
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 breeder's 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 of the plants and parts of plants according to the invention with the active compounds 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 and, in the case of propagation material, in particular in the case of seeds, furthermore by one- or multi-layer coating.
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 varieties, 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 varieties obtained by genetic engineering methods, if appropriate in combination with conventional methods (Genetically Modified Organisms), and parts thereof are treated. The term “parts” or “parts of plants” or “plant parts” has been explained above.
Particularly preferably, plants of the plant varieties which are in each case commercially available or in use are treated according to the invention.
Depending on the plant species or plant varieties, 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, reduced application rates and/or a widening of the activity spectrum and/or an increase in the activity of the substances 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, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products are possible which exceed the effects which were actually to be expected.
The transgenic plants or plant varieties (i.e. those obtained by genetic engineering) which are preferred and to be treated according to the invention include all plants which, in the genetic modification, received genetic material which imparts particularly advantageous useful traits to these plants. Examples of such traits are 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, better quality and/or a higher nutritional value of the harvested products, better storage stability and/or processability of the harvested products. Further and particularly emphasized examples of such properties are a better defence of the plants against animal and microbial pests, such as against insects, mites, phytopathogenic fungi, bacteria and/or viruses, and also increased tolerance of the plants to certain herbicidally active compounds. Examples of transgenic plants which may be mentioned are the important crop plants, such as cereals (wheat, rice), maize, soya beans, potatoes, cotton, oilseed rape and also fruit plants (with the fruits apples, pears, citrus fruits and grapes), and particular emphasis is given to maize, soya beans, potatoes, cotton and oilseed rape. Traits that are particularly emphasized are the increased defence of the plants against insects by toxins formed in the plants, in particular those formed by the genetic material from Bacillus thuringiensis (for example by the genes CryIA(a), CryIA(b), CryIA(c), CryIIA, CryIIIA, CryIIIB2, Cry9c Cry2Ab, Cry3Bb and CryIF and also combinations thereof) (hereinbelow referred to as “Bt plants”). Traits that are furthermore particularly emphasized are the increased tolerance of the plants to certain herbicidally active compounds, for example imidazolinones, sulphonylureas, glyphosate or phosphinotricin (for example the “PAT” gene). The genes which impart the desired traits in question can also be present in combinations with one another in the transgenic plants. Examples of “Bt plants” which may be mentioned are maize varieties, cotton varieties, soya bean varieties and potato varieties which are sold under the trade names YIELD GARD® (for example maize, cotton, soya bean), 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 varieties, cotton varieties and soya bean varieties which are sold under the trade names Roundup Ready® (tolerance to glyphosate, for example maize, cotton, soya bean), 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 include the varieties sold under the name Clearfield® (for example maize). Of course, these statements also apply to plant varieties having these or still-to-be-developed genetic traits, which plant varieties will be developed and/or marketed in the future.
The plants listed can be treated according to the invention in a particularly advantageous manner with the active compound mixtures. The preferred ranges stated above for the mixtures also apply to the treatment of these plants. Particular emphasis is given to the treatment of plants with the mixtures specifically mentioned in the present text.
Method: Safener test after spraying
Solvent: 7 parts by weight of DMF
Emulsifier: 2 parts 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 amounts of solvent and emulsifier, and the concentrate is diluted with tap water to the desired concentration. The desired amount of safener (in the case of mefenpyr-diethyl as WP 20) is mixed into the water used for dilution. Furthermore, 2 g of a.i./l of rapeseed oil methyl ester 500 EW are added. Leaves of winter barley at the 2-leaf stage which are infested by the bird cherry-oat aphid (Rhopalosiphum padi) are treated with the desired active compound and safener concentrations using a spray boom, the water application rate being 3001/ha. Per variant, the test is carried out at least twice. Evaluation is carried out after 7 d and/or 14 d by assessing the plant damage in % and the kill of the grain aphids in % compared to the untreated control. 100% damage means that the plant has died, and 0% means no damage. 100% effect on the grain aphids means that all aphids have been killed; 0% means that none of the aphids have been killed.

Formula to Calculate the Kill Rate of a Combination of Two Active Compounds
The expected activity of a given combination of two active compounds can be calculated as follows (cf. Colby, S. R., “Calculating Synergistic and Antagonistic Responses of Herbicide Combinations”, Weeds 15, pages 20-22, 1967):
if
If the actual insecticidal kill rate exceeds the calculated value, the kill of the combination is superadditive, i.e. a synergistic effect is present. In this case, the actually observed kill rate must exceed the value calculated using the above formula for the expected kill rate (E).
Solvent: water
Adjuvant: rapeseed oil methyl ester (0.1% of a.i./l)
To prepare a suitable application solution, 1 part by weight of formulation is mixed with the appropriate amount of water and the adjuvant and the concentrate is diluted with water to the desired concentration.
Cotton plants (Gossypium herbaceum) which are heavily infested by the cotton aphid (Aphis gossypii) are sprayed to runoff point with the desired concentration of the application solution.
Barley plants (Hordeum vulgare) which are heavily infested by a grain aphid (Metopolophium dirhodum) are sprayed to runoff point with the desired concentration of the application solution.
Bell pepper plants (Capsicum sativum) which are heavily infested by the green peach aphid (Myzus persicae) are sprayed to runoff point with the desired concentration of the application solution.
After the desired period of time, the kill in % is determined. 100% means that all aphids have been killed; 0% means that none of the aphids have been killed. The determined kill rates are entered in Colby's formula.
In this test, for example, the following active compound combination in accordance with the present application shows a synergistically enhanced activity compared to the active compounds applied individually:
Aphis gossypii - Test
Metopolophium dirhodum-Test
Myzus persicae - Test
