Typical liquid diluents and solvents are described in Marsden, Solvents Guide, 2nd Ed., Interscience, New York, 1950. McCutcheon's Detergents and Emulsifiers Annual, Allured Publ. Corp., Ridgewood, New Jersey, as well as Sisely and Wood, Encyclopedia of Surface Active Agents, Chemical Publ. Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth, etc. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer mill or fluid energy mill- Water-dispersible granules can be produced by agglomerating a fine powder composition; see for example, Cross et al., Pesticide Formulations, W-ishington, D.C., 1988, pp 251-259. Suspensions are prepared by wet-milling; see, for example, U.S.3,060,084. Granules and pellets can be made by spraying the active material upon preformed granular carriers or by agglomeration techniques.

Compounds of this invention cai also be mixed with one or more other insecticides, fungicides, nematocides, bactericides, acaricides, semiochemicals, repellants, attractants, pheromones, feeding stimulants or other biologically active compounds to form a multi-component pesticide giving an even broader spectrum of agricultural protection. Examples of other agricultural protectants with which compounds of mis invention can be formulated are: insecticides such as avermectinB, monocrotophos, carbofuran, tetrachlorvinphos, malathion, parathio — methyl, methomyl, chlordimeform, diazinon, deltamethrin, oxamyl, fenvalerate, esfenvalerate, permethrin, profenofos, sulprofos, triflumuron, diflubenzuron, methoprene, buprofezin, thiodicarb, acephate, azinphosmethyl, chlorpyrifos, dimethoate, fipronil, flufenprox, fonophos, isofenphos, methidathion, methamidophos, phosmet, phosphamidon, phosalone, pirimicarb, phorate, tefbufos, trichlorfon, methoxychlor, bifenthrin, biphenate, cyfluthrin, fenpropathrin, fluvalinate, flucythrinate, tralomethrin, metaldehyde and rotenone; fungicides such as carbendazim, thiuram, dodine, maneb, chloroneb, benomyl, cymoxanil, fenpropidine, fenpropimorph, triadimefon, captan, thiophanate- methyl, thiabendazole, phosethyl-Al, chlorothalonil, dichloran, metalaxyl, captafol, iprodione, oxadixyl, vinclozolin, kasugamycin, myclobutanil, tebuconazole, difenoconazole, diniconazole, fluquinconazole, ipconazole, metconazole, penconazole, propiconazole, uniconzole, flutriafol, prochloraz, pyrifenox, fenarimol, triadimenol, diclobutrazol, copper oxychloride, furalaxyl, folpet, flusilazol, blasticidin S, diclomezine, edifenphos, isoprothiolane, iprobenfos, mepronil, neo-asozin, pencycuron, probenazole, pyroquilon, tricyclazole, validamycin, and flutolanil; nematocides such as aldoxycarb, enamiphos and fosthietan; bactericides such as oxytetracyline, streptomycin and tribasϊc copper sulfate; acaricides such as binapacryl, oxythioquinox, chlorobenzilate, dicofol, dienochlor, cyhexatin, hexythiazox, amitraz, propargite, tebufenpyrad and fenbutatin oxide; and biological agents such as Bacillus thuringiensis and baculovirus. In certain instances, combinations with other arthropodicides having a similiar spectrum of control but a different mode of action will be particularly advantageous for resistance management. Arthropod pests are controlled and protection of agronomic crops, animal and human health is achieved by applying one or more of the compounds of this invention, in an 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. A preferred method of application is by spraying. Alternatively, granular formulations of these compounds can be applied to the plant foliage or the soil. Other methods of application include direct and residual sprays, aerial sprays, systemic uptake, baits, eartags, boluses, foggers, fumigants, aerosols, and many others. The compounds can be incorporated into baits that are consumed by the arthropods or in devices such as traps and the like. The compounds of this invention can be applied in their pure state, but most often application will be of a formulation comprising one or more compounds with suitable carriers, diluents, and surfactants and possibly in combination with a fooόTdepending on the contemplated end use. A preferred method of application involves spraying a water dispersion or refined oil solution of the compounds. Combinations with spray oils, spray oil concentrations, spreader stickers, adjuvants, and synergists and other solvents such as piperonyl butoxide often enhance compound efficacy. The rate of application required for effective control will depend on such factors as the species of arthropod 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 ingredient per hectare are sufficient to control pests in agronomic ecosystems, but as little as 0.001 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.

(high impact sytrene) tray with 16 cells were prepared. In 12 of the cells is placed wet filter paper and approximately 8 cm 2 of lima leaf, in the other 4 cells is a 0.5 cm layer of wheat germ diet. Fifteen to twenty third instar larvae of fall armyworm (Spodoptera frugiperda) were placed in a 8 ounce (230 mL) plastic cup. Solutions of each of the test compounds in 75/25 acetone/distilled water solvent were sprayed into the tray and cup. Spraying was accomplished by passing the tray and cup, on a conveyor belt, directly beneath a flat fan hydraulic nozzle which discharged the spray at a rate of 0.5 pounds of active ingredient per acre (about 0.55 kg ha) at 30 psi (207 kPa). The insects were transferred into the tray (one insect per cell). The trays were covered and held at 27°C and 50% relative humidity for 48 h after which time readings were taken on the 12 cells with lima leaves. The 4 remaining cells were read at 7 days for a delayed toxicity reading. Of the compounds tested, the following gave mortality levels of 80% or higher: 24. TESTB Southern Com Rootworm Units consisting of an 8-ounce (230 mL) plastic cup containing 1 one-inch square of a soybean-wheatgerm diet were prepared. The test units were sprayed as described in TEST A with individual solutions of the test compounds. After the spray on the cups had dried, five second-instar larvae of the southern com rootworm {Diabrotica undecimpunctata howardi) were placed into each cup. The cups were then covered and held at 27°C and 50% relative humidity for 48 h, after which time mortality readings were taken. Of the compounds tested, the following gave mortality levels of 80% or higher: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 17*, 21*, 22, 24, 25, 26, 29* 30*, 31*, 32, 33, 36, 37, 38*, 39, 40, 41, 42, 43*, 44, 45*. * Compound sprayed at a rate of 0.13 kg ha. TEST C Boll Weevil Five adult boll weevils {Anthonomus grandis) were placed into each of a series of 9-ounce (260 mL) cups. The test units were sprayed as described in TEST A with individual solutions of the below-listed compounds. Each cup was then covered with a vented lid and held at 27°C. and 50% relative humidity for 48 h, after which time mortality readings were taken. Of the compounds tested, the following gave mortality levels of 80% or higher: 11, 13, 22, 24, 25, 32, 36, 38, 41, 43*, 45*. * Compound sprayed at a rate of 0.13 kg/ha. TEST D Aster Leafhopper Test units were prepared from a series of 12-ounce (350 mL) cups, each containing oat {Avena sativa) seedlings in a 1-inch (2.5 cm) layer of sterilized soil and a 1/2 inch layer of sand. The test units were sprayed as described in TEST A with individual solutions of the compounds. After the oats had dried from the spraying, between 10 and 15 adult aster leafhoppers {Mascrosteles fascifrons) were aspirated into each of the cups covered and vented lids. The cups were held at 27°C and 50% relative humidity for 48 h, after which time mortality readings were taken. Of the compounds tested, the following gave mortality levels of 80% or higher: 1, 2, 3, 4, 7, 10, 21*, 22, 24, 25, 29*, 30, 31*, 32, 33, 36, 37, 38*, 40, 42, 43*, 44, 45*. * Compound sprayed at a rate of 0.13 kg ha. TEST E Black Bean Aphid Individual nasturtium leaves were infested with 10 to 15 aphids (all stages of Aphis fabae) and sprayed with their undersides facing up as described in TEST A. The leaves were then^et in 3/8-inch (0.94 cm) diameter vials containing 4 mL of sugar water solution and covered with a clear plastic 1 -ounce (29 mL) portion cup to prevent escape of aphids that drop from the leaves. The test units were held at 27°C and 50% relative humidity for 48 h, after which time mortality readings were taken. Of the compounds tested, the following resulted in greater than or equal to 80% mortality at 1000 ppm: 22, 25, 32, 33, 36, 38, 41, 42, 45*. * Compound sprayed at a rate of 0.13 kg/ha. TEST F Two-Spotted Spider Mite Onejnch squares (2.54 cm) of kidney bean leaves that had been infested on the undersides with 25 to 30 adult mites {Tetranychus urticae) were sprayed with their undersides facing up on a hydraulic sprayer with a solution of the test compound (acetone/distilled water 75/25 solvent). Spraying was accomplished by passing the leaves, on a conveyer belt, directly beneath a flat fan hydraulic nozzle which discharged the spray at a rate of 0.5 pounds of active ingredient per acre (about 0.55 kg/ha) at 30 psi (207 kPa). The leaf squares were then placed underside-up on a square of wet cotton in a petri dish and the perimeter of the leaf square was tamped down onto the cotton with forceps so that the mites cannot escape onto the untreated leaf surface. The test units were held at 27°C and 50% relative humidity for 48 h, after which time mortality readings were taken. Of the compounds tested, the following resulted in greater than or equal to 80% mortality: 4, 22, 24, 25, 36, 38*, 41, 3*. * Compound sprayed at a rate of 0.13 kg ha TEST G Contact Activity Against Green Leafhopper Nymphs Three rice {Oryza sativά) seedlings, 1.5 leaf stage and about 10 cm tall, are transplanted into a 1/2 oz. (14 mL) plastic cup containing Kumiai Brown artificial soil. Seven milliliters of distilled water is then added to the cup. The test chemical is prepared by first dissolving the chemical in acetone and then adding water to produce a final test concentration of 75:25 (acetone:water). Four plastic cups, each cup serving as a replicate, are then placed on a spray chamber turntable. The cups are sprayed for 45 seconds with 50 mL of the chemical solution at a pressure of 2.0 kg/cm 2 with air atomizing spray nozzles. The turntable completes 7.5 rotations during the 45 second spray interval. After chemical application, treated cups are held in a vented enclosure to dry for about 2 h. After drying, the cups are placed into conical shaped test units and the surface of the soil covered with 2 to 3 mm of quartz sand. Eight to ten 3rd-instar nymphs of the green leafhopper {Nephotettix cincticeps) are transferred into the test units using an aspirator. The test units are held at 27°C and 65% relative humidity- Counts of the number of live and dead nymphs are taken at 24 and 48 h post-infestation. Insects which cannot walk are classified as dead. Of the compounds tested, the following gave mortality levels of 80% or higher at 48 h at 100 ppm: 2, 3, 4, 5, 7, 9, 11, 12, 13, 17, 21, 22, 24, 25. TEST H Contact Activity Against Brown Planthopper Nymphs Three rice {Oryza sativά) seedlings, 1.5 leaf stage and about 10 cm tall are transplanted into a 1/2 oz. (14 mL) plastic cup containing Kumiai Brown artificial soil- Seven milliliters of distilled water is then added to d e cup. The test chemical is prepared by first dissolving the chemical in acetone and then adding water to produce a final test concentration of 75:25 (acetone:water). Four plastic cups, each cup serving as a replicate, are then placed on a spray chamber turntable. The cups are sprayed for 45 seconds with 50 mL of the chemical solution at a pressure of 2.0 kg/cm 2 with air atomizing spray nozzles. The turntable completes 7.5 rotations during the 45 second spray interval. After chemical application, treated cups are held in a vented enclosure to dry for about 2 h. After drying, the cups are placed into conical shaped test units and die surface of the soil covered with 2 to 3 mm of quartz sand. Eight to ten 3rd-instar nymphs of the brown planthopper {Nilaparvata lugens) are transferred into the test units using an aspirator. The test units are held at 27°C and 65% relative humidity, counts of the number of live and dead nymphs are taken at 24 and 48 h post-infestation. Insects which cannot walk are classified as dead. Of the compounds tested, the following gave mortality levels of 80% or higher at 48 h at 100 ppm: 2, 3, 4, 5, 7, 8, 11, 12, 13, 17, 21, 22, 23, 24, 25, 26. TEST I Solution Systemic Activity Against Green Leafhopper Nvmphs The test chemical is added directly into 10 mL of distilled water and dissolved completely. This chemical solution is poured into a conical shaped test unit. Three rice seedlings are then positioned in the unit by a notched sponge disk. The sponge disk allows complete immersion of the seedling root systems in the chemical solution, while the aerial portion of the plant is isolated above the solution. The sponge also prevents the test nymphs from accidentally contacting the test solution. A 7 to 10 mm space, between the surface of the chemical solution and the bottom of the sponge disk, prevents accidental chemical contamination of the sponge. The rice seedlings are allowed to absorb the chemical from the solution for 24 h in a growth chamber held at 27°C and 65% relative humidity. Eight to ten 3rd-instar nymphs of the green leafhopper (Nephotettix cincticeps) are transferred into the test units using an aspirator. The infested units are held under the same temperature and humidity conditions described above. Counts of the number of live and dead nymphs are taken at 24 and 48 h post-infestation. Inspects which cannot walk are classified as dead. Of the compounds tested, the following gave mortality levels of 80% or higher at 48 h at 100 ppm: 2, 3, 5, 7, 11, 12, 13, 17, 21.
