PESTICIDES AND INTERMEDIATES FOR THEIR PREPARATION

The invention relates to compounds of the formula

in which A is a substituted or unsubstituted heterocyclyl group; -E-R is -C(=O)-R, -C(=O)O-R, -C(=O)N(R,)-R, -C(=O)C(=O)-R, -C(=O)C(=O)O-R, -C(=O)C(=O)N(R,)-R or -C(=S)N(R -R;

R is hydrogen or a substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloalkyl, aryl or he¬ teroaryl group; and

R, is hydrogen or a substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloalkyl, aryl or he¬ teroaryl group, in free form or in salt form, where appropriate to tautomers, in free form or in salt form, of these compounds, to a process for the preparation and to the use of these compounds and tautomers, to pesticidal compositions whose active ingredient is selected from amongst these compounds and tautomers, in each case in free form or in agrochemically utiiizable salt form, to a process for the preparation and to the use of these compositions, to plant propagation material treated with these compositions, to a method of controlling pests, to in¬ termediates, in free form or in salt form, for the preparation of these compounds, where appropriate to tautomers, in free form or in salt form, of these intermediates, and to a pro¬ cess for the preparation and to the use of these intermediates.

Certain oxadiazine derivatives have been proposed in the literature as arthropodacidally ac¬ tive ingredients in pesticides. However, the biological properties of these known compounds are not entirely satisfactory in the field of pest control, which is why there is a need to pro¬ vide other compounds which have pesticidal properties, in particular for controlling insects and representatives of the order Acaπna, this object being achieved according to the inven¬ tion by providing the present compounds I.

In some cases, the compounds I can exist as tautomers For example, if -E-R is -C(=O)N(R,)-R and R, is hydrogen, corresponding compounds I, i. e. those in which -E-R is

-C(=O)N(H)-R, can be in equilibrium with the respective tautomers in which -E-R is -C(OH)=N-R. Accordingly, the compounds I hereinabove and hereinbelow are to be under¬ stood as including such tautomers, where appropriate, even though the latter are not men¬ tioned specifically in each individual case.

Compounds I which have at least one basic centre can form, for example, acid addition salts, for example with strong inorganic acids such as mineral acids, for example perchloric acid, sulfunc acid, nitric acid, nitrose acid, a phosphorus acid or a hydrohalic acid, with strong organic carboxyiic acids, such as CrC4alkanecarboxylic acids which are unsubstitu¬ ted or substituted, for example by halogen, for example acetic acid, such as saturated or unsaturated dicarboxylic acids, for example oxalic acid, malonic acid, succinic acid, maleic acid, fumaric acid or phthalic acid, such as hydroxycarboxylic acids, for example ascorbic acid, lactic acid, malic acid, tartaric acid or citric acid, or such as benzoic acid, or with orga¬ nic sulfonic acids, such as Cι-C ₄ alkane- or arylsulfonic acids which are unsubstituted or substituted, for example by halogen, for example methane- or p-toluenesulfonic acid. Com¬ pounds I which have at least one acidic group can form, for example, salts with bases, for example mineral salts such as alkali metal or alkaline earth metal salts, for example sodium, potassium or magnesium salts, or salts with ammonia or an organic amine, such as mor- pholine, pipendine, pyrrolidine, a mono-, di- or tri-lower-alkylamine, for example ethyl-, die- thyl-, tπethyl- or dimethylpropylamine, or a mono-, di- or trihydroxy-lower-alkyiamine, for example mono-, di- or tπethanolamine. Where appropriate, the corresponding internal salts can furthermore be formed. Preferred within the scope of the invention are agrochemically advantageous salts; however, the invention also encompasses salts which have disadvan¬ tage for agrochemical use, for example salts which are toxic to bees or fish, and which are employed, for example, for the isolation or purification of free compounds I or agrochemical¬ ly utilizabie salts thereof. Owing to the close relationship between the compounds I in free form and in the form of their salts, for the purposes of the invention the free compounds I or their salts hereinabove and hereinbelow are respectively to be understood as including, where appropriate, the corresponding salts or the free compounds I. The same applies ana¬ logously to tautomers of compounds I and salts thereof. In general, the free form is pre¬ ferred in each case.

The compounds II and the tautomers thereof, in each case in free form or in salt form, which are employed as starting materials in process variant a) are novel and also are a sub-

ject of the invention. Especially preferred within the scope of the invention are the com¬ pounds of the formula II and the tautomers thereof mentioned in Examples H1 and H2.

I I (VII),

H H NNO _z

which is known, or a tautomer and/or salt thereof with a compound of the formula

Z=C=N-R (VI), which is known or which can be prepared analogously to corresponding known compounds and in which R has the meaning given for formula II and Z is O or S, or, where appropriate, with a tautomer and/or salt thereof, for example analogously to the process described under variant c) for the corresponding reaction of a compound of the formula IV or of a tautomer and/or salt thereof with a compound of the formula VI or, where appropriate, with a tauto¬ mer and/or salt thereof, and/or converting a compound of the formula II or a tautomer there-

of, in each case in free form or in salt form, into another compound of the formula II or a tautomer thereof, separating an isomer mixture which can be obtained in accordance with the process and isolating the desired isomer and/or converting a free compound of the for¬ mula II or a tautomer thereof into a salt or a salt of a compound of the formula II or of a tau¬ tomer thereof into the free compound of the formula II or a tautomer thereof or into another salt.

A compound I or II, respectively, can be converted in a manner known per se into another compound I or II, respectively, by replacing one or more substituents of the starting com¬ pound I or II, respectively, in the customary manner by (an)other substιtuent(s) according to the invention.

For example,

- in compounds I which have an unsubstituted radical A, substituents can be introduced into the radical A; or

- in compounds I which have a substituted radical A, substituents of the radical A can be re¬ placed by other substituents.

Depending on the choice of the reaction conditions and starting materials which are suitable in each case, it is possible, for example, in one reaction step only to replace one substituent by another substituent according to the invention, or a plurality of substituents can be re¬ placed by other substituents according to the invention in the same reaction step.

Salts of compounds I or II, respectively, can be prepared in a manner known per se. Thus, for example, acid addition salts of compounds I or II, respectively, are obtained by treatment with a suitable acid or a suitable ion exchanger reagent and salts with bases are obtained by treatment with a suitable base or with a suitable ion exchanger reagent.

Salts of compounds I or II, respectively, can be converted in the customary manner into the free compounds I or II, respectively, acid addition salts, for example, by treatment with a sui¬ table basic compound or with a suitable ion exchanger reagent and salts with bases, for example, by treatment with a suitable acid or with a suitable ion exchanger reagent.

Salts of compounds I or II, respectively, can be converted in a manner known per se into other salts of compounds I or II, respectively, acid addition salts, for example, into other acid addition salts, for example by treatment of a salt of inorganic acid such as hydrochloride with a suitable metal salt such as a sodium, barium or silver salt, of an acid, for example with silver acetate, in a suitable solvent in which an inorganic salt which forms, for example silver chloride, is insoluble and thus precipitates from the reaction mixture.

Depending on the procedure or the reaction conditions, the compounds I or II, respectively, which have salt-forming properties can be obtained in free form or in the form of salts.

The compounds I and II, respectively, and, where appropriate, in each case the tautomers thereof, in each case in free form or in salt form, can be present in the form of one of the isomers which are possible or as a mixture of these, for example in the form of pure iso- mers, such as antipodes and/or diastereomers, or as isomer mixtures, such as enantiomer mixtures, for example racemates, diastereomer mixtures or racemate mixtures, depending on the number, absolute and relative configuration of asymmetric carbon atoms which occur in the molecule and/or depending on the configuration of non-aromatic double bonds which occur in the molecule; the invention relates to the pure isomers and also to all isomer mix¬ tures which are possible and is to be understood in each case in this sense hereinabove and hereinbelow, even when stereochemical details are not mentioned specifically in each case.

Diastereomer mixtures or racemate mixtures of compounds I or II, respectively, in free form or in salt form, which can be obtained depending on which starting materials and proce¬ dures have been chosen can be separated in a known manner into the pure diasteromers or racemates on the basis of the physicochemical differences of the components, for exam¬ ple by fractional crystallization, distillation and or chromatography.

Enantiomer mixtures, such as racemates, which can be obtained in a similar manner can be resolved into the optical antipodes by known methods, for example by recrystallization from an optically active solvent, by chromatography on chiral adsorbents, for example high- performance liquid chromatography (HPLC) on acetyl celulose, with the aid of suitable mi¬ croorganisms, by cleavage with specific, immobilized enzymes, via the formation of inclu¬ sion compounds, for example using chiral crown ethers, where only one enantiomer is com-

plexed, or by conversion into diastereomeric salts, for example by reacting a basic end-pro¬ duct racemate with an optically active acid, such as a carboxyiic acid, for example camphor, tartaric or malic acid, or sulfonic acid, for example camphorsulfonic acid, and separating the diastereomer mixture which can be obtained in this manner, for example by fractional cry¬ stallization based on their differing solubilities, to give the diastereomers, from which the de¬ sired enantiomer can be set free by the action of suitable agents, for example basic agents.

Pure diastereomers or enantiomers can be obtained according to the invention not only by separating suitable isomer mixtures, but also by generally known methods of diastereose- lective or enantioselective synthesis, for example by carrying out the process according to the invention with starting materials of a suitable stereochemistry.

It is advantageous to isolate or synthesize in each case the biologically more effective iso¬ mer, for example enantiomer or diastereomer, or isomer mixture, for example enantiomer mixture or diastereomer mixture, if the individual components have a different biological ac¬ tivity.

The compounds I and II, respectively, in free form or in salt form, can, if appropriate, also be obtained in the form of hydrates and/or include other solvents, for example those which may have been used for the crystallization of compounds which are present in solid form.

The invention relates to all those embodiments of the process by which, starting from a compound obtainable at any level of the process as starting material or intermediate, all or some of the missing steps are carried out or a starting material is used in the form of a deri¬ vative and/or salt and/or racemates or antipodes thereof or, in particular, is formed under the reaction conditions.

Those starting materials and intermediates, in each case in free form or in salt form, which lead to the compounds I or salts thereof which have been described at the outset as being particularly valuable are preferably used in the process of the present invention.

In particular, the invention relates to the preparation processes described in Examples H1 to

H9.

Starting materials and intermediates, in each case in free form or salt form, which are used in accordance with the invention for the preparation of the compounds I or salts thereof and which are novel, a process for their preparation, and their use as starting materials and in¬ termediates for the preparation of the compounds I are also a subject of the invention; in particular, this applies to the compounds II.

The compounds I according to the invention are preventively and/or curatively valuable ac¬ tive ingredients in the field of pest control, even at low rates of application, which have a ve¬ ry favorable biocidal spectrum and are well tolerated by warm-blooded species, fish and plants. The active ingredients according to the invention act against all or individual deve¬ lopmental stages of normally sensitive, but also resistant, animal pests, such as insects or representatives of the order Acarina. The insecticidal or acaricidal activity of the active in¬ gredients according to the invention can manifest itself directly, i. e. in destruction of the pests, which takes place either immediately or only after some time has elapsed, for exam¬ ple during ecdysis, or indirectly, for example in a reduced oviposition and/or hatching rate, a good activity corresponding to a destruction rate (mortality) of at least 50 to 60%.

The active ingredients according to the invention can be used for controlling, i. e. containing or destroying, pests of the abovementioned type which occur in particular on plants, especi¬ ally on useful plants and ornamentals in agriculture, in horticulture and in forests, or on or¬ gans, such as fruits, flowers, foliage, stalks, tubers or roots, of such plants, and in some ca¬ ses even plant organs which are formed at a later point in time remain protected against these pests.

Suitable target crops are, in particular, cereals, such as wheat, barley, rye, oats, rice, maize or sorghum; beet, such as sugar or fodder beet; fruit, for example pomaceous fruit, stone fruit or soft fruit, such as apples, pears, plums, peaches, almonds, cherries or berries, for example strawberries, raspberries or blackberries; leguminous crops, such as beans, lentils,

peas or soya; oil crops, such as oilseed rape, mustard, poppies, olives, sunflowers, coco¬ nut, castor, cocoa or ground nuts; cucurbits, such as pumpkins, cucumbers or melons; fibre plants, such as cotton, flax, hemp or jute; citrus fruit, such as oranges, lemons, grapefruit or tangerines; vegetables, such as spinach, lettuce, asparagus, cabbages, carrots, onions, to¬ matoes, potatoes or bell peppers; Lauraceae, such as avocado, Cinnamonium or camphor; and also tobacco, nuts, coffee, eggplants, sugarcane, tea, pepper, grapevines, hops, the plantain family, latex plants and ornamentals.

The active ingredients according to the invention are especially suitable for controlling Aphis craccivora, Diabrotica balteata, Myzus persicae and Nilaparvata lugens in vegetable, maize and rice crops.

Other fields of application of the active ingredients according to the invention are the protec¬ tion of stored products and stores and of material, such as wood, textiles, floor coverings or buildings, and, in the hygiene sector, particularly the protection of humans, domestic ani¬ mals and productive livestock against pests of the abovementioned type.

The invention therefore also relates to pesticidal compositions such as emulsifiable concen¬ trates, suspension concentrates, directly sprayable or dilutable solutions, spreadable pastes, dilute emulsions, soluble powders, dispersible powders, wettable powders, dusts, granules or encapsulations in polymeric substances, which comprise - at least - one of the active ingredients according to the invention and which are to be selected to suit the inten¬ ded aims and the prevailing circumstances.

In these compositions, the active ingredient is employed in pure form, a solid active ingredi¬ ent for example in a specific particle size, or, preferably, together with - at least - one of the auxiliaries conventionally used in the art of formulation, such as extenders, for example sol¬ vents or solid carriers, or such as surface-active compounds (surfactants).

Examples of suitable solvents are: unhydrogenated or partially hydrogenated aromatic hy¬ drocarbons, preferably the fractions C ₈ to C, ₂ of alkylbenzenes, such as xylene mixtures, al- kylated naphthalenes or tetrahydronaphthalene, aliphatic or cycloaliphatic hydrocarbons, such as paraffins or cyclohexane, alcohols such as ethanol, propanol or butanol, glycols and their ethers and esters such as propylene glycol, dipropylene glycol ether, ethylene gly-

col or ethylene glycol monomethyl ether or ethylene glycol monoethyl ether, ketones, such as cyclohexanone, isophorone or diacetone alcohol, strongly polar solvents, such as N-me- thylpyrrolid-2-one, dimethyl sulfoxide or N.N-dimethylformamide, water, unepoxidized or epoxidized vegetable oils, such as unexpodized or epoxidized rapeseed, castor, coconut or soya oil, and siiicone oils.

Solid carriers which are used for example for dusts and dispersible powders are, as a rule, ground natural minerals such as calcite, talc, kaolin, montmorillonite or attapulgite. To im¬ prove the physical properties, it is also possible to add highly disperse silicas or highly dis¬ perse absorbtive polymers. Suitable particulate adsorptive carriers for granules are porous types, such as pumice, brick grit, sepiolite or bentonite, and suitable non-sorptive carrier materials are calcite or sand. In addition, a large number of granulated materials of inorga¬ nic or organic nature can be used, in particular dolomite or comminuted plant residues.

Suitable surface-active compounds are, depending on the type of the active ingredient to be formulated, non-ionic, cationic and/or anionic surfactants or surfactant mixtures which have good emulsifying, dispersing and wetting properties. The surfactants mentioned below are only to be considered as examples; a large number of further surfactants which are conven¬ tionally used in the art of formulation and suitable according to the invention are described in the relevant literature.

Suitable non-ionic surfactants are, especially, polyglycol ether derivatives of aliphatic or cyc- loaliphatic alcohols, of saturated or unsaturated fatty acids or of alkyl phenols which may contain approximately 3 to approximately 30 glycol ether groups and approximately 8 to approximately 20 carbon atoms in the (cyclo)aliphatic hydrocarbon radical or approximately 6 to approximately 18 carbon atoms in the alkyl moiety of the alkyl phenols. Also suitable are water-soluble polyethylene oxide adducts with polypropylene glycol, ethylenediaminopo- lypropylene glycol or alkyl polypropylene glycol having 1 to approximately 10 carbon atoms in the alkyl chain and approximately 20 to approximately 250 ethylene glycol ether groups and approximately 10 to approximately 100 propylene glycol ether groups. Normally, the abovementioned compounds contain 1 to approximately 5 ethylene glycol units per propy¬ lene glycol unit. Examples which may be mentioned are nonylphenoxypolyethoxyethanol, castor oil polyglycol ether, polypropylene glycol/polyethylene oxide adducts, tributylpheno-

xypolyethoxyethanol, polyethylene glycol or octylphenoxypolyethoxyethanol. Also suitable are fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate.

The cationic surfactants are, especially, quarternary ammonium salts which generally have at least one alkyl radical of approximately 8 to approximately 22 C atoms as substituents and as further substituents (unhalogenated or halogenated) lower alkyl or hydroxyalkyl or benzyl radicals. The salts are preferably in the form of halides, methylsulfates or ethylsul- fates. Examples are stearyltrimethylammonium chloride and benzylbis(2-chloroethyl)ethyl- ammonium bromide.

Examples of suitable anionic surfactants are water-soluble soaps or water-soluble synthetic surface-active compounds. Examples of suitable soaps are the alkali, alkaline earth or (un¬ substituted or substituted) ammonium salts of fatty acids having approximately 10 to appro¬ ximately 22 C atoms, such as the sodium or potassium salts of oleic or stearic acid, or of natural fatty acid mixtures which are obtainable for example from coconut or tall oil; mention must also be made of the fatty acid methyl taurates. However, synthetic surfactants are used more frequently, in particular fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylaryl sulfonates. As a rule, the fatty sulfonates and fatty sulfates are pre¬ sent as alkali, alkaline earth or (substituted or unsubstituted) ammonium salts and they ge¬ nerally have an alkyl radical of approximately 8 to approximately 22 C atoms, alkyl also to be understood as including the alkyl moiety of acyl radicals; examples which may be men¬ tioned are the sodium or calcium salts of lignosulfonic acid, of the dodecylsulfuric ester or of a fatty alcohol sulfate mixture prepared from natural fatty acids. This group also includes the salts of the sulfuric esters and sulfonic acids of fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonyl groups and a fatty acid radical of approximately 8 to approximately 22 C atoms. Examples of alkylarylsulfonates are the sodium, calcium or triethanolammonium salts of decylbenzenesulfonic acid, of dibutyl- naphthalenesulfonic acid or of a naphthalenesuifonic acid/formaldehyde condensate. Also possible are, furthermore, suitable phosphates, such as salts of the phosphoric ester of a p- nonylphenol/(4-14)ethylene oxide adduct, or phospholipids.

As a rule, the compositions comprise from 0.0001 to 99.9999 %, in particular 0.1 to 95 %, of active ingredient, and 0.0001 to 99.9999 %, in particular 5 to 99.9 %, of - at least - one solid or liquid auxiliary, it being possible, as a rule, for 0 to 25 %, in particular 0.1 to 20 %, of the

compositions to be surfactants (% in each case is per cent by weight). While concentrated compositions are more preferred as commercially available goods, the end user uses, as a rule, dilute compositions which have considerably lower concentrations of active ingredient.

The activity of the compositions according to the invention can be broadened considerably, and adapted to prevailing circumstances, by adding other insecticidally or acaricidally active ingredients. Suitable additions to active ingredients here are, for example, representatives of the following class of active ingredients: organophosphorus compounds, nitrophenol deri¬ vatives, thioureas, juvenile hormones, formamidines, benzophenone derivatives, ureas, pyrrole derivatives, carbamates, pyrethroids, chlorinated hydrocarbons, acylureas, pyridyl- methyleneamino derivatives and Bacillus thuringiensis preparations. The compositions can also comprise further solid or liquid auxiliaries, such as stabilizers, for example unepoxidi- zed or epoxidized vegetable oils (for example epoxidized coconut oil, rapeseed oil or soya oil), antifoams, for example silicone oil, preservatives, viscosity regulators, binders and/or tackifiers, fertilizers or other active ingredients for achieving specific effects, for example bactericides, fungicides, nematocides, plant activators, molluscicides or herbicides.

The compositions according to the invention are prepared in a manner known per se, in the absence of auxiliaries for example by grinding, screening and/or compressing a solid active ingredient and in the presence of at least one auxiliary for example by intimately mixing and/or grinding the active ingredient with the auxiliary (auxiliaries). These processes for the preparation of the compositions and the use of the compounds I for the preparation of these compositions are also a subject of the invention.

The application methods for the compositions, that is the methods of controlling pests of the abovementioned type, such as spraying, atomizing, dusting, brushing on, dressing, scatte¬ ring or pouring - which are to be selected to suit the intended aims of the prevailing circum¬ stances - and the use of the compositions for controlling pests of the abovementioned type are other subjects of the invention. Typical rates of concentration are between 0.1 and 1000 ppm, preferably between 0.1 and 500 ppm, of active ingredient. The rate of application per hectare is generally 1 to 2000 g of active ingredient per hectare, in particular 10 to 1000 g/ha, preferably 10 to 600 g/ha.

A preferred method of application in the field of crop protection is application to the foliage of the plants (foliar application), it being possible to select frequency and rate of application to match the danger of infestation with the pest in question. Alternatively, the active ingredi¬ ent can reach the plants via the root system (systemic action), by drenching the locus of the plants with a liquid composition or by incorporating the active ingredient in solid form into the locus of the plants, for example into the soil, for example in the form of granules (soil application). In the case of paddy rice crops, such granules can be metered into the flooded paddy-field

The compositions according to the invention are also suitable for the protection of plant pro¬ pagation material, for example seeds, such as fruit, tubers or kernels, or nursery plants, against pests of the abovementioned type. The propagation mateπal can be treated with the compositions prior to planting, for example seed can be treated prior to sowing. Alternative¬ ly, the compositions can be applied to seed kernels (coating), either by soaking the kernels in a liquid composition or by applying a layer of a solid composition. It is also possible to apply the compositions when the propagation material is planted to the site of application, for example into the seed furrow during drilling These treatment methods for plant propaga¬ tion material and the plant propagation material thus treated are further subjects of the in¬ vention

In this test, compounds of Tables 2 to 4 show good activity. In particular, the compounds nos. 2.1 , 2.2 and 2.20 have an efficacy of over 80 %.

Example B12: Activity aoainst Mvzus persicae (systemic application! Pea seedlings are infected with Myzus persicae, and the roots are subsequently placed into a spray mixture which comprises 400 ppm of active ingredient, whereupon the seedlings are incubated at 20°. 3 and 6 days later, the test is evaluated. The percentage reduction in population (% activity) is determined by comparing the number of dead aphids on the trea¬ ted and on untreated plants.

In this test, compounds of Tables 2 to 4 show good activity. In particular, the compounds nos. 2.1 , 2.2, 2.17, 2.20, 2.39, 2.50, 2.52, 2.62 to 2.65, 3 1 to 3.8, 3.11 to 3.15, 3.19 to 3.26, 3.28 to 3.36, 3.38 to 3.40, 3.42, 3.44, 3.47, 3.50, 3.54, 3.57 to 3.61 and 3.66 to 3.70 have an efficacy of over 80 %.

Example B13: Activity against Nephotettix cincticeps (foliar application) Rice plants are sprayed with an aqueous emulsion spray mixture which comprises 400 ppm of active ingredient and, after the spray coating has dried on, populated with larvae (2nd and 3rd instar) of Nephotettix cincticeps. 21 days later, the test is evaluated. The percen¬ tage reduction in population (% activity) is determined by comparing the number of surviving leaf hoppers on the treated and on untreated plants. In this test, compounds of Tables 2 to 4 show good activity.

Example B14: Activity against Nephotettix cincticeps (systemic application) Rice plants in pots are placed into an aqueous emulsion spray mixture which comprises 400 ppm of active ingredient. The plants are subsequently populated with larvae (2nd and 3rd instar) of Nephotettix cincticeps. 6 days later, the test is evaluated. The percentage reduc¬ tion in population (% activity) is determined by comparing the number of surviving leaf hop

pers on the treated and on untreated plants.

In this test, compounds of Tables 2 to 4 show good activity.

Example B15: Activity against Nilaparvata luoens (foliar application)

Rice plants are sprayed with an aqueous emulsion spray mixture which comprises 400 ppm of active ingredient and, after the spray coating has dried on, populated with larvae (2nd and 3rd instar) of Nilaparvata lugens. 21 days later, the test is evaluated. The percentage reduction in population (% activity) is determined by comparing the number of surviving leaf hoppers on the treated and on untreated plants.
