This invention relates to certain anthranilamides, their N-oxides, salts and compositions suitable for agronomic and nonagronomic uses, and methods of their use for controlling invertebrate pests such as arthropods in both agronomic and nonagronomic environments.
The control of invertebrate pests is extremely important in achieving high crop efficiency. Damage by invertebrate pests to growing and stored agronomic crops can cause significant reduction in productivity and thereby result in increased costs to the consumer. The control of invertebrate pests in forestry, greenhouse crops, ornamentals, nursery crops, stored food and fiber products, livestock, household, turf, wood products, and public and animal health is also important. Many products are commercially available for these purposes, but the need continues for new compounds which are more effective, less costly, less toxic, environmentally safer or have different modes of action.

As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having,” “contains” or “containing,” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a composition, a mixture, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, mixture, process, method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).
Also, the indefinite articles “a” and “an” preceding an element or component of the invention are intended to be nonrestrictive regarding the number of instances (i.e. occurrences) of the element or component. Therefore “a” or “an” should be read to include one or at least one, and the singular word form of the element or component also includes the plural unless the number is obviously meant to be singular. For example, a composition of the present invention comprises a biologically effective amount of “a” compound of Formula 1 which should be read that the composition includes one or at least one compound of Formula 1.
In the above recitations, the term “alkyl”, used either alone or in compound words such as “alkylthio” or “haloalkyl” includes straight-chain or branched alkyl, such as, methyl, ethyl, ii-propyl, i-propyl, or the different butyl, pentyl or hexyl isomers. The term “1-2 alkyl” indicates that one or two of the available positions for that substituent may be alkyl which are independently selected. “Alkenyl” includes straight-chain or branched alkenes such as ethenyl, 1-propenyl, 2-propenyl, and the different butenyl, pentenyl and hexenyl isomers. “Alkenyl” also includes polyenes such as 1,2-propadienyl and 2,4-hexadienyl. “Alkynyl” includes straight-chain or branched alkynes such as ethynyl, 1-propynyl, 2-propynyl and the different butynyl, pentynyl and hexynyl isomers. “Alkynyl” can also include moieties comprised of multiple triple bonds such as 2,5-hexadiynyl. “Cycloalkyl” includes, for example, cyclopropyl, cyclobutyl, cyclopentyl, and cyclohexyl. “Alkoxy” includes, for example, methoxy, ethoxy, n-propyloxy, isopropyloxy and the different butoxy, pentoxy and hexyloxy isomers. “Alkylthio” includes branched or straight-chain alkylthio moieties such as methylthio, ethylthio, and the different propylthio and butylthio isomers. “Alkylsulfinyl” includes both enantiomers of an alkylsulfinyl group.

Examples of “alkylsulfonyl” include CH3S(O)2, CH3CH2S(O)2, CH3CH2CH2S(O)2, (CH3)2CHS(O)2 and the different butylsulfonyl isomers. “Alkylamino”, “dialkylamino”, “cycloalkylamino”, and the like, are defined analogously to the above examples.
The term “halogen”, either alone or in compound words such as “haloalkyl”, includes fluorine, chlorine, bromine or iodine. The term “1-2 halogen” indicates that one or two of the available positions for that substituent may be halogen which are independently selected. Further, when used in compound words such as “haloalkyl”, said allyl may be partially or fully substituted with halogen atoms which may be the same or different. Examples of “haloalkyl” include F3C, ClCH2, CF3CH2 and CF3CCl2. The terms “haloalkenyl”, “haloalkynyl”, “haloalkoxy”, “haloalkylthio”, and the like, are defined analogously to the term “haloalkyl”. Examples of “haloalkenyl” include (Cl)2C═CHCH2 and CF3CH2CH═CHCH2. Examples of “haloalkynyl” include HC≡CCHCl, CF3C≡C, CCl3C≡C and FCH2C≡CCH2.

The total number of carbon atoms in a substituent group is indicated by the “Ci-Cj” prefix where i and j are numbers from 1 to 8. For example, C1-C4 alkylsulfonyl designates methylsulfonyl through butylsulfonyl.
The term “nonaromatic carbocyclic ring” denotes fully saturated carbocyclic rings as well as partially or fully unsaturated carbocyclic rings where the Hückel rule is not satisfied. The term “nonaromatic heterocyclic ring” denotes fully saturated heterocyclic rings as well as partially or fully unsaturated heterocyclic rings where the Hückel rule is not satisfied. The heterocyclic ring systems can be attached through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen. The term “optionally substituted” in connection with aromatic ring groups refers to groups that are unsubstituted or have at least one non-hydrogen substituent. Commonly, the number of optional substituents (when present) ranges from one to four.
In the above recitations, when a compound of Formula 1 is comprised of one or more heterocyclic rings, all substituents are attached to these rings through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen.
When a compound is substituted with a substituent bearing a subscript that indicates the number of said substituents can exceed 1, said substituents (when they exceed 1) are independently selected from the group of defined substituents. Further, when the subscript indicates a range, e.g. (R5)1-4, then the number of substituents may be selected from the integers between 1 and 4 inclusive. When a group contains a substituent which can be hydrogen, for example R2 or R6, then, when this substituent is taken as hydrogen, it is recognized that this is equivalent to said group being unsubstituted.
One skilled in the art recognizes that “pyridinyl” and “pyridyl” are equivalent alternative names for an organic radical formed by removing a hydrogen atom from a pyridine ring to form an attachment point; accordingly “pyridinyl” and “pyridyl” are used herein as synonyms.
Compounds of this invention can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other stereoisomer(s) or when separated from the other stereoisomer(s). Additionally, the skilled artisan knows how to separate, enrich, and/or to selectively prepare said stereoisomers. The compounds of the invention may be present as a mixture of stereoisomers, individual stereoisomers, or as an optically active form.
One skilled in the art will appreciate that not all nitrogen-containing heterocycles can form N-oxides since the nitrogen requires an available lone pair for oxidation to the oxide; one skilled in the art will recognize those nitrogen-containing heterocycles which can form N-oxides. One skilled in the art will also recognize that tertiary amines can form N-oxides. Synthetic methods for the preparation of N-oxides of heterocycles and tertiary amines are very well known by one skilled in the art including the oxidation of heterocycles and tertiary amines with peroxy acids such as peracetic and m-chloroperbenzoic acid (MCPBA), hydrogen peroxide, alkyl hydroperoxides such as t-butyl hydroperoxide, sodium perborate, and dioxiranes such as dimethyldioxirane. These methods for the preparation of N-oxides have been extensively described and reviewed in the literature; see for example: T. L. Gilchrist in Comprehensive Organic Synthesis, vol. 7, pp 748-750, S. V. Ley, Ed., Pergamon Press; M. Tisler and B. Stanovnik in Comprehensive Heterocyclic Chemistry, vol. 3, pp 18-20, A. J.

Stanovnik in Advances in Heterocyclic Chemistry, vol. 9, pp 285-291, A. R. Katritzky and A. J. Boulton, Eds., Academic Press; and G. W. H. Cheeseman and E. S. G. Werstiuk in Advances in Heterocyclic Chemistry, vol. 22, pp 390-392, A. R. Katritzky and A. J. Boulton, Eds., Academic Press.
The salts of the compounds of the invention include acid-addition salts with inorganic or organic acids such as hydrobromic, hydrochloric, nitric, phosphoric, sulfuric, acetic, butyric, fumaric, lactic, maleic, malonic, oxalic, propionic, salicylic, tartaric, 4-toluenesulfonic or valeric acids. The salts of the compounds of the invention also include those formed with organic bases (e.g., pyridine, ammonia, or triethylamine) or inorganic bases (e.g., hydrides, hydroxides, or carbonates of sodium, potassium, lithium, calcium, magnesium or barium) when the compound contains an acidic group such as a carboxylic acid. Accordingly, the present invention comprises compounds selected from Formula 1, N-oxides and agriculturally suitable salts thereof.
As noted above, G is a 3- to 6-membered nonaromatic carbocyclic or heterocyclic ring, optionally including one or two ring members selected from the group consisting of C(═O), S(O) or S(O)2 and optionally substituted with 1 to 4 substituents selected from the group consisting of C1-C2 alkyl, halogen, —CN, —NO2 and C1-C2 alkoxy. Examples of 3- to 6-membered nonaromatic carbocyclic or heterocyclic rings include those illustrated as G-1 through G-45 in Exhibit 1. Note that the attachment point on these G groups is illustrated as floating; the G group can be attached to the remainder of Formula 1 through any available carbon or nitrogen of the G group by replacement of a hydrogen atom. The optional substituents can be attached to any carbon or nitrogen by replacement of a hydrogen atom (said substituents are not illustrated in Exhibit 1 since they are optional substituents). Note that when G comprises a ring selected from G-24 through G-31, G-34 and G-35, Q2 may be selected from O, S, NH or substituted N.

Compounds of Formula 1 can be prepared by one or more of the following methods and variations as described in Schemes 1-12. The definitions of X, J, B, L, R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14 and R15 in the compounds of Formulae 1-11 below are as defined above in the Summary of the Invention unless indicated otherwise. Formulae 1a-1j are subsets of Formula 1, and Formulae 9a-9c are subsets of Formula 9.
Compounds of Formula 1a, wherein B is NR13, NOR13 or NNR14R15, can be prepared by the reaction of compounds of Formula 1c with corresponding amines, alkoxylamines or hydrazines of Formula 2 as outlined in Scheme 1. This reaction can be run neat or in a variety of suitable solvents including water, methanol, ethanol, acetonitrile or tetrahydrofuran with optimum temperatures ranging from room temperature to the reflux temperature of the solvent. The general reaction of ketones with amines to produce imines, oximes and hydrazones is well documented in the chemical literature. For examples of this type see A. Franke, Liebigs Ann. Chem. 1982, (4), 794-804. In a subsequent step, amides of Formula 1a can be converted to thioamides of Formula 1b using a variety of standard thio transfer reagents including phosphorus pentasulfide and 2,4-bis-(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane 2,4-disulfide (Lawesson's reagent).

Imines of Formula 1f can be converted to compounds of Formula 1e wherein R4 and R15 are H by treatment with aqueous acids such as hydrochloric acid, sulfuric acid or acetic acid, optionally with co-solvent such as methanol or tetrahydrofuran.
This reaction can be run neat or in a variety of suitable solvents including methanol, ethanol, acetonitrile or tetrahydrofuran with optimum temperatures ranging from room temperature to the reflux temperature of the solvent.

Undheim, Acta Chemica Scand., Series B 1984, B38(2), 109-112. Preparation of compounds of Formulae 1d, 1e or 1f, wherein R4 is other than H (e.g., alkyl, alkylcarbonyl, etc.), can be accomplished by standard alkylation or acylation of the amide by treatment with a base (such as sodium hydride in N,N-dimethylformamide) and the alkylating or acylating reagent.

This reaction can be run in a variety of suitable solvents including acetonitrile, dichloromethane, chloroform or tetrahydrofuran with optimum temperatures ranging from 0° C. to the reflux temperature of the solvent. The acylation of isatins is well documented in the chemical literature. For example see T. L. Jacobs et al., Organic Syntheses 1948, 28, 70-2 and A. Ferranti et al., Arch. Pharm. 1985, 318(5) 415-421. In a subsequent step, amides of Formula 1g can be converted to thioamides of Formula 1h using a variety of standard thio transfer reagents including phosphorus pentasulfide and Lawesson's reagent.
Isatins of Formula 4 are well known and can be prepared from aniline derivatives following literature procedures such as those described by F. D. Popp, Adv. Heterocycl. Chem. 1975, 18, 1-58 and J. F. M. Da Silva et al., Journal of the Brazilian Chemical Society 2001, 12(3), 273-324.
The acid chlorides of Formula 5 are available from the corresponding acids of Formula 6 by known methods such as chlorination with thionyl chloride or oxalyl chloride as outlined in Scheme 4. The mixed anhydrides can be prepared in situ from the corresponding acids by treatment with an alkyl chloroformate or alkylsulfonyl chloride in the presence of a base such as triethylamine, pyridine or 3-picoline by well known methods. The acids of Formula 6 can be prepared as disclosed in WO 03/016283 and U.S. Pat. No. 6,747,047.

It is recognized that some reagents and reaction conditions described above for preparing compounds of Formula 1 may not be compatible with certain functionalities present in the intermediates. In these instances, the incorporation of protection/deprotection sequences or functional group interconversions into the synthesis will aid in obtaining the desired products. The use and choice of the protecting groups will be apparent to one skilled in chemical synthesis (see, for example, Greene, T. W.; Wuts, P. G. M. Protective Groups in Organic Synthesis, 2nd ed.; Wiley: New York, 1991). One skilled in the art will recognize that, in some cases, after the introduction of a given reagent as it is depicted in any individual scheme, it may be necessary to perform additional routine synthetic steps not described in detail to complete the synthesis of compounds of Formula 1. One skilled in the art will also recognize that it may be necessary to perform a combination of the steps illustrated in the above schemes in an order other than that implied by the particular sequence presented to prepare the compounds of Formula 1.
One skilled in the art will also recognize that compounds of Formula 1 and the intermediates described herein can be subjected to various electrophilic, nucleophilic, radical, organometallic, oxidation, and reduction reactions to add substituents or modify existing substituents.

Compounds of this invention will generally be used as a formulation or composition with a suitable carrier comprising at least one of a liquid diluent, a solid diluent or a surfactant. The formulation or composition ingredients are selected to be consistent with the physical properties of the active ingredient, mode of application and environmental factors such as soil type, moisture and temperature. Useful formulations include liquids such as solutions (including emulsifiable concentrates), suspensions, emulsions (including microemulsions and/or suspoemulsions) and the like which optionally can be thickened into gels. Useful formulations further include solids such as dusts, powders, granules, pellets, tablets, films (including seed coatings), and the like which can be water-dispersible (“wettable”) or water-soluble. Active ingredient can be (micro)encapsulated and further formed into a suspension or solid formulation; alternatively the entire formulation of active ingredient can be encapsulated (or “overcoated”). Encapsulation can control or delay release of the active ingredient. Sprayable formulations can be extended in suitable media and used at spray volumes from about one to several hundred liters per hectare. High-strength compositions are primarily used as intermediates for further formulation.
The formulations will typically contain effective amounts of active ingredient, diluent and surfactant within the following approximate ranges which add up to 100 percent by weight.
Typical solid diluents are described in Watkins, et al., Handbook of Insecticide Dust Diluents and Carriers, 2nd Ed., Dorland Books, Caldwell, N.J.

In the following Examples, all percentages are by weight and all formulations are prepared in conventional ways. Compound numbers refer to compounds in Index Tables A-E. Without further elaboration, it is believed that one skilled in the art using the preceding description can utilize the present invention to its fullest extent. The following Examples are, therefore, to be constructed as merely illustrative, and not limiting of the disclosure in any way whatsoever. Percentages are by weight except where otherwise indicated.
Compounds of this invention are characterized by favorable metabolic and/or soil residual patterns and exhibit activity controlling a spectrum of agronomic and nonagronomic invertebrate pests. Compounds of this invention are also characterized by favorable foliar and or soil-applied systemicity in plants exhibiting translocation to protect foliage and other plant parts not directly contacted with invertebrate pest control compositions comprising the present compounds. In the context of this disclosure “invertebrate pest control” means inhibition of invertebrate pest development (including mortality, feeding reduction, and/or mating disruption) and as a result significant reduction in feeding or injury to an agronomic crop or damage to a building structure caused by the invertebrate pest; related expressions are defined analogously.
The term “agronomic” refers to the production of field crops such as for food and fiber and includes the growth of corn, soybeans and other legumes, rice, cereal (e.g., wheat, oats, barley, rye, rice, maize), leafy vegetables (e.g., lettuce, cabbage, and other cole crops), fruiting vegetables (e.g., tomatoes, pepper, eggplant, crucifers and cucurbits), potatoes, sweet potatoes, grapes, cotton, tree fruits (e.g., pome, stone and citrus), small fruit (berries, cherries) and other specialty crops (e.g., canola, sunflower, olives). The term “agronomic” also refers to the production of such crops that contain genetic material introduced by genetic engineering (i.e. transgenic) or modified by mutagenesis to provide advantageous traits. Examples of such traits include tolerance to herbicides, resistance to phytophagous pests (e.g., insects, mites, aphids, spiders, nematodes, snails, plant-pathogenic fungi, bacteria and viruses), improved plant growth, increased tolerance of adverse growing conditions such as high and low temperatures, low or high soil moisture, and high salinity, increased flowering or fruiting, greater harvest yields, more rapid maturation, higher quality and/or nutritional value of the harvested product, and improved storage or process properties of the harvested products. Transgenic plants can be modified to express multiple traits. Examples of plants containing traits provided by genetic engineering or mutagenesis include varieties of corn, cotton, soybean and potato expressing an insecticidal Bacillus thuringienlsis toxin such as YIELD GARD®, KNOCKOUT®, STARLINK®, BOLLGARD®, NuCOTN® and NEWLEAF®, and herbicide-tolerant varieties of corn, cotton, soybean and rapeseed such as ROUNDUP READY®, LIBERTY LINK®, IMI®, STS® and CLEARFIELD®, as well as crops expressing N-acetyltransferase (GAT) to provide resistance to glyphosate herbicide, or crops containing the HRA gene providing resistance to herbicides inhibiting acetylactate synthase (ALS).
The term “nonagronomic” refers to other horticultural crops (e.g., greenhouse, nursery or ornamental plants not grown in a field), residential and commercial structures in urban and industrial settings, turf (commercial, golf, residential, recreational, etc.), wood products, stored product, agro-forestry and vegetation management, public health (human) and animal health (domestical animals, pets, livestock, poultry, undomestical animals such as wildlife) applications. For reasons of invertebrate pest control spectrum and economic importance, protection of agronomic crops from damage or injury caused by invertebrate pests by controlling invertebrate pests are embodiments of the invention.
As referred to in this disclosure, the term “invertebrate pest” includes arthropods, gastropods and nematodes of economic importance as pests. The term “arthropod” includes insects, mites, spiders, scorpions, centipedes, millipedes, pill bugs and symphylans. The term “gastropod” includes snails, slugs and other Stylommatophora. The term “nematode” includes all of the helminths, such as: roundworms, heartworms, and phytophagous nematodes (Nematoda), flukes (Tematoda), Acanthocephala, and tapeworms (Cestoda). Compounds of this invention exhibit activity against a wide spectrum of foliar-feeding, fruit-feeding, stem or root feeding, seed-feeding, aquatic and soil-inhabiting invertebrate pests which are pests of growing and stored agronomic crops, forestry, greenhouse crops, ornamentals, nursery crops, stored food and fiber products, livestock, household, public health and animal health. Those skilled in the art will appreciate that not all compounds are equally effective against all growth stages of all pests.

General references for these agricultural protectants (i.e. insecticides, fungicides, nematocides, acaricides, herbicides and biological agents) include The Pesticide Manual, 13th Edition, C. D. S. Tomlin, Ed., British Crop Protection Council, Farnham, Surrey, U.K., 2003 and The BioPesticide Manual, 2nd Edition, L. G. Copping, Ed., British Crop Protection Council, Farnham, Surrey, U.K., 2001.
In certain instances, combinations with other arthropodicides having a similar spectrum of control but a different mode of action will be particularly advantageous for resistance management. Thus, compositions of the present invention can further comprise a biologically effective amount of at least one additional invertebrate pest control compound or agent having a similar spectrum of control but a different mode of action. Contacting a plant genetically modified to express a plant protection compound (e.g., protein) or the locus of the plant with a biologically effective amount of a compound of this invention can also provide a broader spectrum of plant protection and be advantageous for resistance management.
In certain instances, combinations of a compound of this invention with other invertebrate pest control compounds or agents can result in a greater-than-additive (i.e. synergistic) effect and/or a less-than-additive effect (i.e. antagonistic). It is always desirable to reduce the quantity of chemical agents released in the environment while ensuring effective pest control. When synergism of invertebrate pest control agents is found at application rates giving agronomically satisfactory levels of pest control, such combinations can be advantageous for lowering crop production cost and reducing environmental load.
Table A lists specific combinations of a compound of Formula 1 with other invertebrate pest control agents illustrative of the mixtures, compositions and methods of the present invention. The first column of Table A lists the specific invertebrate pest control agents (e.g., “Abamectin” in the first line). The second column of Table A lists the mode of action (if known) of the invertebrate pest control agents. The third column of Table A lists embodiment(s) of ranges of weight ratios for rates at which the invertebrate pest control agent can be applied relative to a compound of Formula 1, an N-oxide, or a salt thereof, (e.g., “50:1 to 1:50” of abamectin relative to a compound of Formula 1 by weight). Thus, for example, the first line of Table A specifically discloses the combination of a compound of Formula 1 with abamectin can be applied in a weight ratio between 50:1 to 1:50. The remaining lines of Table A are to be construed similarly.

The specific mixtures listed in Table B typically combine a compound of Formula 1 with the other invertebrate pest agent in the ratios specified in Table A.
Invertebrate pests are controlled in agronomic and nonagronomic applications by applying a composition comprising a compound of this invention, in a biologically effective amount, to the environment of the pests, including the agronomic and/or nonagronomic locus of infestation, to the area to be protected, or directly on the pests to be controlled. Agronomic applications include protecting a field crop from invertebrate pests typically by applying a composition or a mixture of the invention to the seed of the crop before the planting, to the foliage, stems, flowers and/or fruit of crop plants, or to the soil or other growth medium before or after the crop is planted. Nonagronomic applications refer to invertebrate pest control in the areas other than fields of crop plants. Nonagronomic applications include control of invertebrate pests in stored grains, beans and other foodstuffs, and in textiles such as clothing and carpets. Nonagronomic applications also include invertebrate pest control in ornamental plants, forests, in yards, along roadsides and railroad rights of way, and on turf such as lawns, golf courses and pastures. Nonagronomic applications also include invertebrate pest control in houses and other buildings which may be occupied by humans and/or companion, farm, ranch, zoo or other animals. Nonagronomic applications also include the control of pests such as termites that can damage wood or other structural materials used in buildings.
Nonagronomic applications also include protecting human and animal health by controlling invertebrate pests that are parasitic or transmit infectious diseases. The controlling of animal parasites includes controlling external parasites that are parasitic to the surface of the body of the host animal (e.g., shoulders, armpits, abdomen, inner part of the thighs) and internal parasites that are parasitic to the inside of the body of the host animal (e.g., stomach, intestine, lung, veins, under the skin, lymphatic tissue). External parasitic or disease transmitting pests include, for example, chiggers, ticks, lice, mosquitoes, flies, mange, mites and fleas. Internal parasites include heartworms, hookworms and helminths. Compounds and compositions of the present invention are particular suitable for combating external parasitic or disease transmitting pests.
Compounds and compositions of the present invention are suitable for combating parasites that infest agricultural working animals, such as cattle, sheep, goats, horses, pigs, donkeys, camels, buffalos, rabbits, hens, turkeys, ducks, geese and bees; pet animals and domestic animals such as dogs, cats, pet birds and aquarium fish; as well as so-called experimental animals, such as hamsters, guinea pigs, rats and mice. By combating these parasites, fatalities and performance reduction (in term of meat, milk, wool, skins, eggs, honey, etc.) are to be reduced, so that applying a composition comprising a compound of the present invention is intended to allow more economic and simple husbandry of animals.
Nonagronomic applications in the veterinary sector takes place in the known manner, by enteral administration in the form of, for example, tablets, capsules, drinks, drenching preparations, granulates, pastes, boli, feed-through procedures, suppositories; by parenteral administration, such as by injection (including intramuscular, subcutaneous, intravenous, intraperitoneal), implants; by nasal administration; by dermal administration, for example, in the form of immersion or dipping, spraying, pouring, washing, coating with powder, and through bodied devices such as neck collars, ear marks, tail marks, limb measuring tapes or halters which comprise compounds or compositions of the present invention.
Therefore, the present invention further comprises a method for controlling an invertebrate pest in agronomic and/or nonagronomic applications, comprising contacting the invertebrate pest or its environment with a biologically effective amount of one or more of the compounds of the invention, or with a composition comprising at least one such compound or a composition comprising at least one such compound and a biologically effective amount of at least one additional biologically active compound or agent. Examples of suitable compositions comprising a compound of the invention and a biologically effective amount of at least one additional biologically active compound or agent include granular compositions wherein the additional active compound is present on the same granule as the compound of the invention or on granules separate from those of the compound of the invention.
One embodiment of a method of contact is by spraying. Alternatively, a granular composition comprising a compound of the invention can be applied to the plant foliage or the soil. Compounds of this invention can also be effectively delivered through plant uptake by contacting the plant with a composition comprising a compound of this invention applied as a soil drench of a liquid formulation, a granular formulation to the soil, a nursery box treatment or a dip of transplants. Of note is a composition of the present invention in the form of a soil drench liquid formulation. Also of note is a method for controlling an invertebrate pest comprising contacting the soil environment of the invertebrate pest with a biologically effective amount of a compound of the present invention. Of further note are compounds of this invention also effective by topical application to the locus of infestation. Other methods of contact include application of a compound or a composition of the invention by direct and residual sprays, aerial sprays, gels, seed coatings, nicroencapsulations, systemic uptake, baits, ear tags, boluses, foggers, fumigants, aerosols, dusts and many others. One embodiment of a method of contact is a dimensionally stable fertilizer granule, stick or tablet comprising a mixture or composition of the invention. The compounds of this invention can also be impregnated into materials for fabricating invertebrate control devices (e.g., insect netting). Seed coatings can be applied to all types of seeds, including those from which plants genetically transformed to express specialized traits will germinate. Representative examples include those expressing proteins toxic to invertebrate pests, such as Bacillus thuringiensis toxin or those expressing herbicide resistance, such as “Roundup Ready” seed.
The compounds of this invention can be incorporated into a bait composition that is consumed by an invertebrate pest or used within a device such as a trap, bait station, and the like. Such a bait composition can be in the form of granules which comprise (a) active ingredients, namely a biologically effective amount of a compound of Formula 1, an N-oxide, or salt thereof; (b) one or more food materials; optionally (c) an attractant, and optionally (d) one or more humectants. Of note are granules or bait compositions which comprise between about 0.001-5% active ingredients, about 40-99% food material and/or attractant; and optionally about 0.05-10% humectants, which are effective in controlling soil invertebrate pests at very low application rates, particularly at doses of active ingredient that are lethal by ingestion rather than by direct contact. Some food materials can function both as a food source and an attractant. Food materials include carbohydrates, proteins and lipids. Examples of food materials are vegetable flour, sugar, starches, animal fat, vegetable oil, yeast extracts and milk solids. Examples of attractants are odorants and flavorants, such as fruit or plant extracts, perfume, or other animal or plant component, pheromones or other agents known to attract a target invertebrate pest. Examples of humectants, i.e. moisture retaining agents, are glycols and other polyols, glycerine and sorbitol. Of note is a bait composition (and a method utilizing such a bait composition) used to control at least one invertebrate pest selected from the group consisting of ants, termites and cockroaches. A device for controlling an invertebrate pest can comprise the present bait composition and a housing adapted to receive the bait composition, wherein the housing has at least one opening sized to permit the invertebrate pest to pass through the opening so the invertebrate pest can gain access to the bait composition from a location outside the housing, and wherein the housing is further adapted to be placed in or near a locus of potential or known activity for the invertebrate pest.
The compounds of this invention can be applied without other adjuvants, but most often application will be of a formulation comprising one or more active ingredients with suitable carriers, diluents, and surfactants and possibly in combination with a food depending on the contemplated end use. One method of application involves spraying a water dispersion or refined oil solution of a compound of the present invention. Combinations with spray oils, spray oil concentrations, spreader stickers, adjuvants, other solvents, and synergists such as piperonyl butoxide often enhance compound efficacy. For nonagronomic uses such sprays can be applied from spray containers such as a can, a bottle or other container, either by means of a pump or by releasing it from a pressurized container, e.g., a pressurized aerosol spray can. Such spray compositions can take various forms, for example, sprays, mists, foams, fumes or fog. Such spray compositions thus can further comprise propellants, foaming agents, etc. as the case may be. Of note is a spray composition comprising a biologically effective amount of a compound or a composition of the present invention and a carrier. One embodiment of such a spray composition comprises a biologically effective amount of a compound or a composition of the present invention and a propellant. Representative propellants include, but are not limited to, methane, ethane, propane, butane, isobutane, butene, pentane, isopentane, neopentane, pentene, hydrofluorocarbons, chlorofluorocarbons, dimethyl ether, and mixtures of the foregoing. Of note is a spray composition (and a method utilizing such a spray composition dispensed from a spray container) used to control at least one invertebrate pest selected from the group consisting of mosquitoes, black flies, stable flies, deer flies, horse flies, wasps, yellow jackets, hornets, ticks, spiders, ants, gnats, and the like, including individually or in combinations.
The rate of application required for effective control (i.e. “biologically effective amount”) will depend on such factors as the species of invertebrate to be controlled, the pest's life cycle, life stage, its size, location, time of year, host crop or animal, feeding behavior, mating behavior, ambient moisture, temperature, and the like. Under normal circumstances, application rates of about 0.01 to 2 kg of active ingredients per hectare are sufficient to control pests in agronomic ecosystems, but as little as 0.0001 kg/hectare may be sufficient or as much as 8 kg/hectare may be required. For nonagronomic applications, effective use rates will range from about 1.0 to 50 mg/square meter but as little as 0.1 mg/square meter may be sufficient or as much as 150 mg/square meter may be required. One skilled in the art can easily determine the biologically effective amount necessary for the desired level of invertebrate pest control.

For evaluating control of diamondback moth (Plutella xylostella) the test unit consisted of a small open container with a 12-14-day-old radish plant inside. This was pre-infested with 10-15 neonate larvae on a piece of insect diet by use of a core sampler to remove a plug from a sheet of hardened insect diet having many larvae growing on it and transfer the plug containing larvae and diet to the test unit. The larvae moved onto the test plant as the diet plug dried out.
Test compounds were formulated using a solution containing 10% acetone, 90% water and 300 ppm X-77® Spreader Lo-Foam Formula non-ionic surfactant containing alkylarylpolyoxyethylene, free fatty acids, glycols and isopropanol (Loveland Industries, Inc. Greeley, Colo., USA). The formulated compounds were applied in 1 mL of liquid through a SUJ2 atomizer nozzle with ⅛ JJ custom body (Spraying Systems Co. Wheaton, Ill., USA) positioned 1.27 cm (0.5 inches) above the top of each test unit. Test compounds were sprayed at 50 ppm and replicated three times. After spraying of the formulated test compound, each test unit was allowed to dry for 1 hour and then a black, screened cap was placed on top. The test units were held for 6 days in a growth chamber at 25° C. and 70% relative humidity. Each test unit was visually assessed for insect mortality.
Of the compounds tested, the following resulted in at least 80% insect mortality: 1, 3, 4, 7, 8, 11, 12 and 14.
For evaluating control of fall armyworm (Spodoptera frugiperda) the test unit consisted of a small open container with a 4-5-day-old corn (maize) plant inside. This was pre-infested (using a core sampler) with 10-15 1-day-old larvae on a piece of insect diet.
Test compounds were formulated and sprayed at 50 ppm as described for Test A. The applications were replicated three times. After spraying, the test units were maintained in a growth chamber and then visually rated as described for Test A.
Of the compounds tested, the following resulted in at least 80% insect mortality: 1 and 11.
