Compounds of formula 1 can be prepared by reacting benzoxazinones of formula 2 with an amine of formula HNR4R5as shown in Scheme 1. This reaction can be carried out in the absence of a solvent or in various suitable solvents including tetrahydrofuran, diethyl ether, diocloxane, toluene, dichloromethane or chloroform, and the optimum temperature is between room temperature and the reflux temperature of the solvent. The general reaction of benzoxazinones with amines to form anthranilamides is well documented in the chemical literature. A review of the benzoxazinone chemistry is published by Jakobsen et al., Biorganic and Medicinal Chemistry 2000, 8, 2095-2103 and the references cited therein. See also GM Coppola, J. Heterocyclic Chemistry 1999, 36, 563-588.

Compounds of Formula 1 can also be prepared from haloanthranilic diamides of Formula 3 (where X is halogen, preferably iodine or bromine) by the coupling method shown in Scheme 2. By reacting a compound of Formula 3 with a metal cyanide (e.g. zinc or potassium cyanide), optionally in the presence of a suitable palladium catalyst [e.g. tetrakis (triphenylphosphine) palladium (0) or dichlorobis (triphenylphosphine) palladium (II) and optionally in the presence of a metal halide (e.g. cuprous iodide, zinc iodide or potassium iodide) in a suitable solvent such as acetonitrile, N, N-dimethylformamide or N -methylpyrrolidinone, optionally at a temperature ranging from room temperature to the reflux temperature of the solvent, gives compounds of formula 1. Tetrahydrofuran or dioxane may also be a suitable solvent when a palladium catalyst is used in the coupling reaction.

Cyanobenzoxazinones of Formula 2 can be prepared as shown in Scheme 3. By reacting a halobenzoxazinone of Formula 4 (wherein X is halogen, preferably iodine or bromine) with a metal cyanide by coupling similar to that described above for Scheme 2 (optionally to a palladium catalyst and optionally in the presence of a metal halide) a compound of formula 2 is obtained.

PL 209 772 B1

Cyanobenzoxazinones of formula 2 can also be prepared as shown in scheme 4 by coupling the pyrazole carboxylic acid of formula 5 with a cyanoanthranilic acid of formula 6. This reaction comprises the sequential addition of methanesulfonyl chloride in the presence of a tertiary amine such as triethylamine or pyridine to the pyrazole carboxylic acid of Formula 5, followed by the addition of cyanoanthranilic acid of Formula 6, followed by a second addition of a tertiary amine and methanesulfonyl chloride.

Scheme 5 illustrates another method for the preparation of the benzoxazinones of formula 2 comprising the coupling of the isatoic anhydride of formula 7 with a pyrazole carboxylic acid chloride of formula 8. Solvents such as pyridine or pyridine / acetonitrile are suitable for this reaction. The acid chlorides of formula 8 can be obtained from the corresponding acids of formula 5 by known methods such as chlorination with thionyl chloride or oxalyl chloride.

PL 209 772 B1

As shown in Scheme 6, haloanthranilic diamides of formula 3 can be prepared by reacting benzoxazinones of formula 4, wherein X is halogen, with an amine of formula HNR4R5, in a manner similar to that described above for Scheme 1. The conditions for this reaction are similar to Scheme 1.

As shown in Scheme 7, the halo-benzoxazinones of formula 4 (wherein X is halogen) can be prepared by direct coupling of pyridylpyrazole carboxylic acid of formula 5 with haloanthranilic acid of formula 9 (wherein X is halogen) in a manner similar to that described above in with reference to diagram 4. This reaction comprises sequentially adding methanesulfonyl chloride to the pyrazole carboxylic acid of formula 5 in the presence of a tertiary amine such as triethylamine or pyridine, followed by addition of haloanthranilic acid of formula 9 and adding a second tertiary amine and methanesulfonyl chloride. Typically, a good yield of benzoxazinone is obtained by this method.

As shown in Scheme 8, a halo benzoxazinone of formula 4 can also be prepared by coupling an isatoic anhydride of formula 10 (wherein X is halogen) with a pyrazole carboxylic acid chloride of formula 8 in a manner similar to that described above for Scheme 5.

By reacting haloanthranilic acid of Formula 9 (wherein X is halogen) with metal cyanide using the same coupling procedure described above Referring to Scheme 2 (optionally in the presence of a palladium catalyst and optionally in the presence of a metal halide), the compound of formula 6 is obtained.

As illustrated in Scheme 10, cyanoisatoic anhydrides of formula 7 can be prepared from cyanoanthranilic acids of formula 6 by reaction with phosgene (or a phosgene equivalent such as triphosgene) or with an alkyl chloroformate (e.g. methyl chloroformate) in a suitable solvent such as such as toluene or tetrahydrofuran.

As shown in Scheme 11, the haloanthranilic acids of formula 9 can be prepared by direct halogenation of unsubstituted anthranilic acid of formula 11 with N-chlorosuccinimide (NCS), N-bromosuccinimide (NBS), or N-iodosuccinimide (NIS), respectively, in solvents such as N, N-dimethylformamide (DMF) to give the corresponding halo-substituted acid of formula 9.

PL 209 772 B1

As shown in Scheme 12, haloisatoic anhydrides of formula 10 can be prepared from haloanthranilic acids of formula 9 by reaction with phosgene (or a phosgene equivalent such as triphosgene) or with an alkyl chloroformate (e.g. methyl chloroformate) in a suitable solvent such as such as toluene or tetrahydrofuran.

Pyridylpyrazole carboxylic acids of formula 5 can be prepared as outlined in Scheme 13. Reaction of pyrazole 12 with a 2-halopyridine of formula 13 in the presence of a suitable base such as potassium carbonate in a solvent such as N, N-dimethylformamide or acetonitrile is prepared from good yield of 1-pyridylpyrazole 14, with good specificity with respect to the desired regiochemistry. Metallation of 14 with lithium diisopropylamide (LDA) followed by decomposition of the lithium salt with carbon dioxide gives the pyrazole carboxylic acid of formula 5.

The starting pyrazoles of formula 12, in which R.2 is CF3, Cl or Br, are known compounds. The pyrazole of formula 12 wherein R.2 is CF3, can be prepared by methods described in the literature (J. Fluorine Chem. 1991, 53 (1), 61-70). Pyrazoles of formula 12 wherein R.2 is Cl or Br, can also be obtained by methods described in the literature (H. Reimlinger and A. Van Overstraeten, Chem. Ber. 1966, 99 (10), 3350-7). A useful alternative preparation of compounds of Formula 12 wherein R.2 is Cl or Br, shown in Scheme 14. Metallation of sulfamoylpyrazole of formula 15 with n-butyllithium followed by direct halogenation of the anion with hexachloroethane (where R2 is Cl) or 1,2-dibromotetrachloroethane (when R.2 is Br), the halogenated derivatives of formula 16 (wherein R2 is Cl or Br). Removal of the sulfamoyl group with trifluoroacetic acid (TFA) at room temperature is easy, so that the pyrazoles of formula 12 in which R2 is Cl or Br, respectively.

PL 209 772 B1

As an alternative to the method outlined in Scheme 13, the pyrazole carboxylic acids of Formula 5 where R2 is CF3, can also be obtained as shown in Scheme 15. By reaction of the compound of formula 17 (wherein R8 is C1-C4 alkyl) with an appropriate base in a suitable organic solvent yields the cyclized product of formula 18 upon neutralization with an acid such as acetic acid.

A suitable base may be, for example, but not limited to, sodium hydride, potassium t-butoxide, sodium dimsylate (CH3S (O) CH2-Na+), alkali metal carbonates or hydroxides (such as lithium, sodium or potassium), tetraalkyl- (e.g. methyl, ethyl or butyl) ammonium or 2-t-butylimino-2-diethylamino-1,3-dimethylperhydro-1-fluorides or hydroxides , 3,2-diazaphosphonine. A suitable organic solvent may be, for example, but not limited to, acetone, acetonitrile, tetrahydrofuran, dichloromethane, dimethylsulfoxide, or N, N-dimethylformamide. The cyclization reaction is typically carried out at a temperature in the range of about 0-120 ° C. The interaction of the solvent, base, temperature and addition time are interdependent, and the choice of reaction conditions is important to minimize the formation of by-products. The preferred base is tetrabutylammonium fluoride.

Dehydration of the compound of formula 18 to form the compound of formula 19 followed by hydrolysis of the carboxylic acid ester to the carboxylic acid affords the compound of formula 5. Dehydration is accomplished by treatment with a catalytic amount of an appropriate acid. This acid catalyst may be, for example, but not limited to, sulfuric acid. This reaction is usually carried out in an organic solvent. As will be appreciated by those skilled in the art, dehydration reactions can be carried out in a wide variety of solvents, for example acetic acid, typically at a temperature in the range of about 0-200 ° C, more preferably between about 0-100 ° C. The carboxylic esters of formula 19 can be converted to the carboxylic acids of formula 5 by a variety of methods, including nucleophilic cleavage under anhydrous conditions or by hydrolytic methods involving the use of different acids or bases (see review of the methods in TW Greene and PGM Wuts, Protective Groups in Organic Synthesis, 2nd edition, John Wiley & amp; Sons, Inc., New York, 1991, pp. 224-269). For the method of Scheme 15, base-catalyzed hydrolytic methods are preferred. Suitable bases include alkali metal (such as lithium, sodium or potassium) hydroxides. For example, the ester can be dissolved in a mixture of water and an alcohol such as ethanol. Upon treatment with sodium hydroxide or potassium hydroxide, the ester is saponified to give the sodium or potassium salt of the carboxylic acid. Acidification with a strong acid such as hydrochloric acid or sulfuric acid affords the carboxylic acid of formula 5.

Compounds of formula 17, wherein R.2 is CF3, can be prepared as outlined in Scheme 16. Treatment of a hydrazine compound of formula 20 with a ketone of formula CH3COR2 in a solvent such as water, methanol or acetic acid, gives the hydrazone of formula 21.

It will be appreciated by one skilled in the art that this reaction may require catalysis with the additionally introduced acid and may also require an elevated temperature, depending on the substituent system of the hydrazone molecule of formula 21. Reaction of the hydrazone of formula 21 with an alkyl chloro oxalate in a suitable organic solvent such as e.g. but not limited to, dichloromethane or tetrahydrofuran in the presence of an acid binding agent such as triethylamine provides the compound of Formula 17. This reaction is usually carried out at about 0-100 ° C. Hydrazine compounds of Formula 20 can be prepared by known methods, such as by reacting the appropriate halopyridine of Formula 13 with hydrazine.

As an alternative to the process outlined in Scheme 13, the pyrazole carboxylic acids of Formula 5 wherein R2 is Cl or Br, can also be obtained as shown in Scheme 17. Oxidation of a compound of formula 22, optionally in the presence of an acid, gives a compound of formula 19, where R2 is Cl or Br. Hydrolysis of the carboxylic ester to the carboxylic acid provides the compound of Formula 5.

PL 209 772 B1

The oxidizing agent for converting the compound of formula 22 to the compound of formula 19 may be hydrogen peroxide, organic peroxides, potassium persulfate, sodium persulfate, ammonium persulfate, potassium monopersulfate (e.g., Oxone®) or potassium permanganate. To obtain complete conversion, at least 1 equivalent of oxidizing agent versus the compound of Formula 22 should be used, preferably 1-2 equivalents. Such oxidation is usually carried out in the presence of a solvent. The solvent may be an ether such as tetrahydrofuran, p-dioxane and the like, an organic ester such as ethyl acetate, dimethyl carbonate and the like, or a polar aprotic organic solvent such as N, N-dimethylformamide, acetonitrile, etc. Acids suitable for use in the oxidation step include inorganic acids such as sulfuric acid, phosphoric acid and the like, and organic acids such as acetic acid, benzoic acid, etc. 1-5 equivalents of the acid may be used. The preferred oxidant is potassium persulfate and the oxidation is preferably carried out in the presence of sulfuric acid. This reaction can be performed by mixing the compound of Formula 22 in the desired solvent and, optionally, the acid used. The oxidant can then be added at the required rate. The reaction temperature usually ranges from as little as about 0 ° C to the reflux temperature of the solvent to provide a reasonable time to complete the reaction. Suitable methods for converting the ester of formula 19 to the carboxylic acid of formula 5 are described above with reference to Scheme 15.

Compounds of formula 22, wherein R.2 is halogen and R8 is C1-C4 alkyl, can be prepared from the appropriate compounds of formula 23 as outlined in scheme 18.

Treatment of a compound of formula 23 with a halogenating agent, typically in the presence of a solvent, provides the corresponding halogen compound of formula 22.

Halogenating agents that can be used include phosphorus oxyhalides, phosphorus trihalides, phosphorus pentahalides, thionyl chloride, dihalothrialkylphosphates, dihalodiphenylphosphates, oxalyl chloride, and phosgene. Preference is given to using phosphorus oxyhalides and phosphorus pentahalides . To obtain complete conversion, at least 0.33 equivalents of phosphorus oxyhalide versus the compound of Formula 23 should be used, preferably between about 0.33 and 1.2 equivalents. To obtain complete conversion, at least 0.20 equivalents of phosphorus pentahalide versus the compound of Formula 23 should be used, preferably between about 0.20 and 1.0 equivalents. Common solvents for the halogenation reaction include halogenated alkanes such as dichloromethane, chloroform, chlorobutane and the like, aromatic solvents such as benzene, xylene, chlorobenzene and the like, ethers such as tetrahydrofuran, p-dioxane, diethyl ether etc. and polar aprotic solvents such as acetonitrile, N, N-dimethylformamide and the like. An organic base such as triethylamine, pyridine, N, N-dimethylaniline and the like may optionally be used. Alternatively, a catalyst such as N, N-dimethylformamide may also be added. A method in which the solvent is acetonitrile and no base is used is preferred. Usually, neither a base nor a catalyst is needed when acetonitrile is used as the solvent. A preferred method involves mixing the compound of Formula 23 with acetonitrile. The halogenating agent is then added at a convenient time and the mixture is kept at the desired temperature until the reaction is complete. Reaction temperature

The reaction time is usually from 20 ° C to the boiling point of acetonitrile, and the reaction time is usually less than 2 hours. The reaction mixture is then neutralized with an inorganic base such as sodium bicarbonate, sodium hydroxide and the like, or with an organic base such as sodium acetate. The desired product of Formula 22 can be isolated by methods known to those skilled in the art, including crystallization, extraction, and distillation.

Alternatively, compounds of formula 22 wherein R2 is Br or Cl, can be prepared by treatment of the corresponding compounds of formula 22, wherein R2 is a different halogen atom (e.g. Cl for the preparation of a compound of formula 22 where R2 is Br) or a sulfonate group such as p-toluenesulfonate, benzenesulfonate and methanesulfonate with hydrogen bromide or hydrogen chloride, respectively. Thus, a halogen atom or a sulfonate substituent as R.2 in the compound of formula 22 is replaced by Br or Cl from hydrogen bromide or hydrogen chloride, respectively. The reaction is carried out in a suitable solvent such as dibromomethane, dichloromethane, acetic acid, ethyl acetate, or acetonitrile. This reaction can be carried out at or near atmospheric pressure, or at a pressure higher than atmospheric in a pressure vessel. The halogenating agent can be introduced in gaseous form into the reaction mixture containing the compound of Formula 23 and a solvent. When R.2 where the starting material of formula 22 is a halogen atom such as Cl, the reaction is preferably carried out in such a way that rinsing or other suitable means to remove the hydrogen halide formed in the reaction are used. Alternatively, the halogenating agent may first be dissolved in an inert solvent in which it is readily soluble (such as acetic acid) before combining with the compound of Formula 23, either neat or in solution. This reaction may be conducted at about 0-100 ° C, most conveniently at about ambient temperature (e.g., about 10-40 ° C), more preferably at about 20-30 ° C. Addition of a Lewis acid catalyst (such as aluminum tribromide to prepare the compound of Formula 22 where R2 represents Br) may facilitate the reaction. The product of Formula 22 is isolated by the usual methods known to those skilled in the art, including extraction, distillation, and crystallization.

The starting compounds of formula 22 in which R.2 represents a sulfonate group, can be prepared from the corresponding compounds of formula 23 by known methods such as treatment with a sulfonyl chloride (e.g. p-toluenesulfonyl chloride) and a base such as a tertiary amine (e.g. triethylamine) in a suitable solvent such as dichloromethane.

As an alternative to the process shown in Scheme 13, the pyrazole carboxylic acids of Formula 5 where R2 is haloalkoxy, also can be obtained as shown in Scheme 19. A compound of formula 23 is oxidized to a compound of formula 24. The conditions for this oxidation reaction are described with reference to the conversion of compound 22 to compound 19 in Scheme 17.

The intermediate of formula 24 is then alkylated to give the compound of formula 19 (wherein R2 denotes haloalkoxy) by reaction with a suitable halogenating agent such as

Such as haloalkyl halide or sulfonate. The reaction is performed in the presence of at least one equivalent of a base. Suitable bases include inorganic bases such as alkali metal carbonates, hydroxides, and hydrides (such as lithium, sodium, or potassium), or organic bases such as triethylamine, diisopropylethylamine, and 1,8-diazabicyclo [5.4.0] undec-7-ene . This reaction is typically carried out in solvents which may be alcohols such as methanol and ethanol, halogenated alkanes such as dichloromethane, aromatic solvents such as benzene, toluene and chlorobenzene, ethers such as tetrahydrofuran and polar aprotic solvents such as acetonitrile , N, N-dimethylformamide and the like. Alcohols and polar aprotic solvents are preferred for use with inorganic bases. Preferably, potassium carbonate is used as the base and N, N-dimethylformamide or acetonitrile as solvent. This reaction is usually carried out at a temperature of 0-150 ° C, most often in the range of ambient temperature to 100 ° C. The ester of formula 24 can then be converted to the carboxylic acid of formula 5 by the methods described for the conversion of the compound of formula 19 to the compound of formula 5 in Scheme 15.

Compounds of Formula 23 can be prepared from compounds of Formula 20 as outlined in Scheme 20. In this process, a hydrazine compound of Formula 20 is reacted with a compound of Formula 25 (a fumarate ester or a maleate ester, or a mixture thereof, in the presence of a base) and solvent.

The base used in Scheme 20 is typically a metal alkoxide such as sodium methoxide, potassium methoxide, sodium ethoxide, potassium ethoxide, potassium t-butoxide, lithium t-butoxide, etc. Polar protic and polar aprotic organic solvents such as alcohols, acetonitrile, tetrahydrofuran, N, N-dimethylformamide, dimethyl sulfoxide and the like. Preferred solvents are alcohols such as methanol and ethanol. It is particularly preferably the same alcohol that is included in the fumarate or maleate and the alcoholate base. This reaction is typically performed by mixing the compound of Formula 20 and the base in a solvent. The mixture can be warmed or cooled to the desired temperature and the compound of formula 25 added over a period of time. Typically, reactions are carried out at a temperature between 0 ° C and the boiling point of the solvent used. The reaction can be carried out at superatmospheric pressure to increase the boiling point of the solvent. A temperature in the range of about 30-90 ° C is usually preferred. The reaction mixture can then be acidified by adding an organic acid such as acetic acid and the like, or an inorganic acid such as hydrochloric acid, sulfuric acid and the like. The desired product of formula 23 can be isolated by methods known to those skilled in the art, such as crystallization, extraction or distillation.

It should be appreciated that for some of the reagents and reaction conditions described above for the preparation of the compounds of Formula I, incompatibility with certain functional groups in the intermediates may exist. In such cases, introducing protection / deprotection sequences or functional group interconversions into the synthesis will facilitate the preparation of the desired products. The use and selection of protecting groups will be apparent to one skilled in the art of chemical synthesis (see, e.g., TW Greene; PGM Wuts, Protective Groups in

In some cases, combinations with other invertebrate pest control compounds and agents, having a similar spectrum but a different mode of action, will be of particular benefit to counter resistance. Thus, the compositions of the invention may contain a biologically effective amount of at least one invertebrate pest control compound or agent having a similar spectrum of control but a different control mode. Contacting a genetically modified plant to express a plant protection compound (e.g., protein) or locus of that plant with a biologically effective amount of a compound of the invention may also provide a broader spectrum of plant protection and be beneficial for controlling resistance.

Invertebrate pests are controlled in agricultural and / or non-agricultural applications by applying an effective amount of one or more compounds of the invention to the pest environment, including the agricultural and / or non-agricultural site of infestation, the area to be protected, or directly to the area to be protected. pest control. Thus, a method of controlling invertebrate pests for agricultural and / or non-agricultural use is that the invertebrates or their environment are brought into contact with a biologically effective amount of one or more compounds of the invention, or an agent containing at least one such compound, or an agent containing at least one such compound and an effective amount of at least one additional biologically active compound or agent. Examples of suitable compositions comprising a compound of the invention and an effective amount of at least one additional biologically active compound or agent include granular compositions wherein the additional biologically active compound is present in the same granule as the compound of the invention or in separate granules in addition to the granules containing the compound of the invention.

Spraying is the preferred method of application. Alternatively, a granular agent containing a compound of the invention may be applied to the plant leaves or to the soil. The compounds of the invention can also be effectively delivered to the plant by a systemic route, by contacting the plant with an agent containing a compound of the invention applied as a soil drench liquid, soil granule, seedbed treatment or by dipping seedlings. The compounds may be effective after topical application of an agent containing a compound of the invention to the site of infestation. Other methods of contacting include application of a compound or agent of the invention as a direct or residual spray or air spray, in the form of a gel, seed dressing, microcapsules, systemic absorption, in the form of bait, earrings, boluses, fumigants, fumigants, aerosols. , dust and many other ways. The compounds of the invention may also be impregnated into materials for the production of invertebrate pest control devices (e.g. insect nets).

The compounds of the invention may be incorporated into a bait composition consumed by invertebrates or into devices such as traps, bait stations etc. Such bait compositions may be in the form of granules containing (a) the active ingredient, i.e. a compound of formula I, its N-oxide or salt, (b) one or more food products, (c) optionally an attractant, and (d) optionally one or more humectants. Of note are granules or bait compositions containing about 0.001 - 5% active ingredient, about 40 - 99% food product and / or attractant and optionally about 0.05 - 10% humectants which are effective in controlling soil invertebrate pests in very low application rates, especially at doses of the active ingredient which are lethal by ingestion rather than direct contact. Certain foods that act as both a food source and attractant are noteworthy. Food products include carbohydrates, proteins and lipids. Exemplary food products include vegetable flour, sugar, starches, animal fat, vegetable oil, yeast extracts, and milk solids. Exemplary attractants include fragrances and flavorings such as fruit and plant extracts, fragrances or other animal or plant ingredients, pheromones, or other agents known to attract the target invertebrate pest. Examples of humectants or humectants include glycols and other polyols, glycerin, and sorbitol. Of note is the bait composition (and the method of using such a bait composition) for controlling invertebrate pests.

Including individually or in combination, ants, termites, and cockroaches. The invertebrate pest control device may include a bait composition and a housing for receiving the bait composition, the housing including at least one opening sized such that the invertebrate pest can pass through the opening so that the invertebrate pest may enter. to the bait composition from a place outside the casing, and furthermore, the casing is made to to be placed in a site of potential or known activity, or in the vicinity of an invertebrate pest.

The compounds of the invention may be used alone, but most commonly a formulation containing one or more compounds will be employed with suitable carriers, diluents and surfactants, and optionally in combination with food, depending on the intended end use. A preferred method of application is spraying with an aqueous dispersion or a solution of the compounds in a refined oil. Combination with spray oils, spray oil concentrates, spreading / sticking agents, adjuvants, other solvents and synergistic enhancers such as piperonyl butoxide often enhances the efficacy of the compound. For non-agricultural applications, such spraying may be made from a spray can, such as a can, bottle or other container, by a pump, or by release from a pressurized container, eg, a pressurized aerosol spray can. Such spray compositions can take various forms, for example sprays, mists, mousses, fumes or mists. Such sprays may further contain propellants, foaming agents etc. as the case may be. Of note is a spray composition containing a compound or composition of the invention and a propellant. Representative propellants include, but are not limited to, methane, ethane, propane, isopropane, butane, isobutane, butene, pentane, isopentane, neopentane, pentene, hydrofluorocarbons, chlorofluorocarbons, dimethyl ether, and mixtures thereof. Of note is the spray agent (and the method of using such agent in a spray dispensed from a spray container) to control invertebrate pests including, individually or in combination, mosquitoes, blackflies, bolims, blinders, horse veins, wasps, donkeys, hornets, ticks, spiders ants, mosquitoes, etc.

The applied dose required for effective control (i.e. "biologically active amount)" will depend on factors such as the invertebrate pest species to be controlled, the life cycle of the pest, growth stage, size, location, season, crop or host animal, eating habits, habits. mating season, ambient humidity, temperature, etc. Under normal circumstances, doses in the range of 0.01-2 kg / hectare of active ingredient are sufficient to control pests in agricultural ecosystems, but as low as 0.0001 kg / hectare or as much as 8 kg / hectare may be required. For non-agricultural applications, the effective doses used will be 1.0 - 50 mg / m2however, as little as 0.1 mg / m may suffice2 or it may be necessary to use as much as 150 mg / m2. One skilled in the art can easily determine the amount of biologically active dose for a desired level of invertebrate pest control.

The following tests demonstrate the effectiveness of the compounds according to the invention in controlling certain pests. 'Control efficiency means inhibition of the development of invertebrate pests (including their mortality), resulting in a significant reduction in feeding. The pest control protection afforded by the compounds is not limited to these species, however. A description of the compounds is given in Tables A and B.
