Details of the Invention For descriptive purposes, the following numbering system will be used to describe the values of Q in both the discussion and tables that follow. Compounds of Formula I can be prepared by the reaction of aryl isocyanates of Formula II and substituted indazoles of Formula III as shown in Scheme I. Typical reactions involve the combination of equimolar amounts of II and III in conventional organic solvents including ether, tetrahydrofuran (THF), methylene chloride, chloroform and benzene. The reaction can be run at temperatures ranging from about -20°C to 100°C with temperatures in the range of about -10° to 30°C generally preferred. Substituted indazoles of Formula III, where B is equal to H, can be prepared by the reaction of hydrazine with an α, β-unsaturated ketone of Formula IV (or their precursors) by procedures well documented in the chemical literature (Scheme 2). For a review of pyrazoline synthesis, see El-Rayyes and Al-Awadi, Synthesis, 1028 (1985). For literature describing the synthesis of 3,4- and 3,5-disubstituted pyrazolines, which can be applied to the synthesis of compounds of Formula III, where B is H, see U.S. Patent 3,991,073 and U.S. Patent 4,070,365. Preparation of compounds of Formula I, where B is other than H, OR₇, phenyl or substituted phenyl can be achieved by metallation of the 3a- position of Formula I (where B is H) followed by reaction with a suitable electrophile as depicted in Scheme 3. Procedures for the related transformation of 4-substituted pyrazolines to 4,4-disubstituted pyrazolines are reported in European Patent Application 153127 and can be applied to substituted indazoles of Formula I. Metallation can be accomplished by deprotonation with a strong base, in a suitable solvent and at temperatures ranging from -78°C to 100°C. Useful base for this reaction includes lithium dialkylamides such as lithium diisopropylamide and lithium tetramethylpiperide, alkyl lithium reagents such as n-butyllithium and metal hydrides such as sodium hydride and potassium hydride. Deprotonation of compounds of Formula I, where B is equal to hydrogen, may require two equivalents of base when Y is equal to hydrogen. The reaction can be conducted in many conventional organic solvents and in certain instances a cosolvent may be useful. Suitable solvents include diethylether, tetrahydrofuran, tetrahydropyran, dimethylformamide, hexamethylphosphoramide, benzene and the like. Suitable electrophilic reagents for reaction with the metallated Formula I compounds include alkyl and substituted alkyl halides, alkyl chloroformates, acyl halides, isocyanates, dialkyl carbamoylhalides and related electrophiles which will be known to those skilled in the art. where E⁺ is an electrophilic reagent. An alternative procedure for introduction of the 3a-substituent, which in certain instances may be preferred over that of Scheme 3 due to higher yields and/or greater ease of synthesis, proceeds via the intermediacy of Compound V, wherein the 2-nitrogen has been derivatized with a suitable protecting group. Deprotonation with a strong base such as lithium diisopropylamide, typically in stoichiometric quantities, followed by reaction with any of the previously described electrophiles provides compounds of Formula V where B is other than hydrogen, OR₇, phenyl or substituted phenyl. Removal of the nitrogen protecting group provides the required Formula III intermediate. Nitrogen-protecting groups are well documented in the chemical literature, as are procedures for their preparation and cleavage. Examples include acetyl, trifluoroacetyl, benzoyl, substituted benzoyl, alkoxycarbonyl, benzyl and substituted benzyl. For a review see Greene "Protective Groups in Organic synthesis" (New York: John Wiley and Sons, 1981) pp. 218 to 287. where E⁺ is an electrophile and PG is representative of a suitable nitrogen-protecting group. Formula III compounds where B is equal to hydroxy are prepared by the reaction of hydrazine with a suitably substituted epoxide of Formula VI (Scheme 5, Reaction 1). The epoxides are available from the enones of Formula IV by procedures known in the art, the most widely employed method being epoxidation via the use of alkaline hydrogen peroxide (see. e.g., Wasson and House, Org. Syn., Coll. Vol. 4, 552 (1963)). Compounds of Formula III where B is equal to OR₇ and R₇ is other than hydrogen, may be prepared from the Formula III compounds where B is equal to hydroxy via reaction with electrophilic reagents such as alkyl halides, acyl halides, alkyl chloroformates, chlorosulfonates, isocyanates and dialkyl carbamoylhalides (scheme 5, Reaction 2). Those skilled in the art will recognize that conditions necessary for this transformation including solvent, catalyst, temperature, etc., will vary with the specific electrophile chosen and that protection of the 2-nitrogen may be necessary. where E⁺ and PG are as previously defined. Compounds of Formula III where B is phenyl or substituted phenyl may be prepared by reaction of a substituted ketone of Formula VIII with hydrazine. The Formula VIII compounds are in turn prepared from compounds of Formula VII in a two-step process involving first an aldol or Mannich type reaction on the Formula VII compound followed by conversion of the hydroxyl or dialkylamino group to a leaving group L, examples of which include conversion to the chloride, bromide, tosylate or mesylate by procedures well known in the art. Compounds of Formula IV (or their precursors) are readily prepared from compounds of Formula IX via an aldol condensation followed by dehydration of the aldol, or when J and K are hydrogen via a Mannich reaction followed by elimination of the dialkylamino group. For a general review of these reactions, see March. "Advanced organic Chemistry", 3rd ed., (New York: John Wiley and Sons. 1985) pp. 829 to 834, and House, "Modern Synthetic Reactions", 2nd ed., (Menlo Park, CA: N.A. Benjamin, 1972) pp. 655 to 660. Those skilled in the art will recognize the intermediates of Formula IX, which include compounds such as indanones, tetralones, chromanones, thiochromanones, and the like are well documented in the chemical literature as are procedures for their preparation. Selected examples of Formula IX are available commercially as well. The following Examples further illustrate the invention.

The β isomer represents those compounds where the B substituent is trans to the oxygen of the sulfoxide. Formulation and Use The compounds of this invention will generally be used in formulation with an agriculturally suitable carrier comprising a liquid or solid diluent or an organic solvent. Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates, dry flowables and the like. Many of these can be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from about one to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 1% to 99% by weight of active ingredient(s) and at least one of a) about 0.1% to 20% surfactant(s) and b) about 5% to 99% solid or liquid diluent(s). More specifically, they will contain effective amounts of these ingredients in the following approximate proportions: Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing. Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books, Caldwell, New Jersey. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide," 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0°C. "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. Preferably, ingredients should be approved by the U.S. Environmental Protection Agency for the use intended. The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Patent 3,060,084). Granules and pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See J. E. Browning, "Agglomeration", Chemical Engineering , December 4, 1967, pages 147 and following, and "Perry's Chemical Engineer's Handbook", 4th Ed., McGraw-Hill, New York, 1963, pages 8 to 59 and following. Examples of useful formulations of compounds of the present invention are as follows: Example A Emulsifiable Concentrate 3,3a,4,5-tetrahydro-3a-methyl-N-[4-(trifluoromethyl)phenyl]-2H-benz[g]indazole-2-carboxamide 5% blend of oil soluble sulfonates and polyoxyethylene ethers 4% xylene 91% The ingredients are combined and stirred with gentle warming to speed solution. A fine screen filter is included in packaging operation to insure the absence of any extraneous undissolved material in the product. Example B Wettable Powder Methyl 3,3a,4,5-tetrahydro-2-[[4-(trifluoromethyl)phenylamino]carbonyl]-2H-benz[g]indazole-3a-carboxylate 30% sodium alkylnaphthalenesulfonate 2% sodium ligninsulfonate 2% synthetic amorphous silica 3% kaolinite 63% The active ingredient, warmed to reduce viscosity, is sprayed onto the inert materials in a blender. After grinding in a hammer-mill, the material is reblended and sifted through a 50 mesh screen. Example C Dust Wettable powder of Example B 10% pyrophyllite (powder) 90% The wettable powder and the pyrophyllite diluent are thoroughly blended and then packaged. The product is suitable for use as a dust. Example D Granule 3,3a,4,5-tetrahydro-3a-methyl-N-[4-(trifluoromethyl)phenyl]-2H-benz[g]indazole-2-carboxamide 10% attapulgite granules (low volative matter, 0.71/0.30 mm; U.S.S. No. 25-50 sieves) 90% The active ingredient is dissolved in a suitable solvent and sprayed onto dedusted attapulgite granules in a double cone blender. The granules are warmed to drive off solvent, cooled and packaged. Example E Granule Wettable powder of Example D 15% gypsum 69% potassium sulfate 16% The ingredients are blended in a rotating mixer and water sprayed on to accomplish granulation. When most of the material has reached the desired range of 0.1 to 0.42 mm (U.S.S. No. 18 to 40 sieves), the granules are removed, dried, and screened. Oversize material is crushed to produce additional material in the desired range. These granules contain 4.5% active ingredient. Example F Solution Methyl 3,3a,4,5-tetrahydro-2-[[4-(trifluoromethyl)phenylamino]carbonyl]-2H-benz[g]indazole-3a-carboxylate 10% isophorone 90% The ingredients are combined and stirred to produce a solution suitable for direct, low volume application.

Biological Bacillus thuringiensis Avermectin B. Utility The compounds of the present invention exhibit activity against a wide spectrum of foliar and soil inhabiting insects. Those skilled in the art will recognize that not all compounds are equally effective against all insects, but compounds of this invention display control of many of the economically important pest species of the insect orders Lepidoptera, Homoptera, and Coleoptera among many others. The specific species for which control is exemplified below are: fall armyworm, Spodoptera frugiperda ; boll weevil, Anthonomus grandis ; European corn borer, Ostrinia nubilalis ; southern corn rootworm, Diabrotica undecimpunctata howardi ; aster leafhopper, Macrosteles fascifrons ; Tobacco budworm, Heliothis virescens . The pest control afforded by the compounds of the present invention is not limited, however, to these species. Application Insects are controlled and agricultural drops are protected by applying one or more of the Formula I compounds of this invention, in an effective amount, to the 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 with spray equipment that distributes the compound on the foliage, in the soil, or to the plant part that is infested or needs to be protected. Alternatively, granular formulations of these compounds can be applied to soil or foliage or, optionally, incorporated into the soil. Either aerial or ground application can be used. The substituted indazole(s) of this invention can be applied in its(their) pure state, but most often application will be of a formulation comprising one or more compounds of this invention, in an agriculturally suitable carrier or diluent. A most preferred method of application involves spraying a water dispersion or refined oil solution of the compounds. The rate of application of the Formula I compounds required for effective control will depend on such factors as the species of insect to be controlled, the pest's life stage, its size, its location, the host crop, time of year of application, ambient moisture, temperature conditions, and the like. In general, application rates of 0.05 to 2 kg of active ingredient per hectare are sufficient to provide effective control in large scale field operations under normal circumstances, but as little as 0.01 kg/hectare may be sufficient or as much as 8 kg/hectare may be required, depending upon the factors listed above. The following Examples demonstrate the control efficacy of compounds of Formula I on specific insect pests wherein Compounds 1 through 8 are those of Examples 1 to 8 and Compounds 9 through 181 are as depicted in Tables 19 and 20. Compounds not listed were either not tested or did not effect at least 80% mortality in that screen. Example 9 Fall Armyworm Test units, each consisting of an 8-ounce plastic cup containing a layer of wheat germ diet, approximately 0.5 cm thick, were prepared. Ten third-instar larvae of fall armyworm ( Spodoptera frugiperda ) were placed into each cup. Solutions of each of the below-listed test compounds (acetone/distilled water 75/25 solvent) were sprayed onto the cups, a single solution per cup. Spraying was accomplished by passing the cups, 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 p.s.i. The cups were then covered and held at 27°C and 50% relative humidity for 72 hours, after which time mortality readings were taken. Of the compounds tested on fall armyworm, the following resulted in greater than or equal to 80% mortality: 3, 4, 5, 7, 15, 17, 20, 22, 23, 25, 45, 59, 72, 100, 125, 148, 158, 159, 160, 165, 166, 168, 169, 170, 173, 177, 179, 181.

After the spray on the cups had dried, five third-instar larvae of the southern corn rootworm ( Diabrotica undecimpunctata howardi ) were placed into each cup. A moistened dental wick was inserted into each cup to prevent drying and the cups were then covered. The cups were then held at 27°C and 50% relative humidity for 48 hours, after which time mortality readings were taken. Of the compounds tested on Southern rootworm, the following resulted in greater than or equal to 80% mortality: 1, 2, 3, 4, 5, 7, 15, 16, 17, 20, 21, 22, 23, 25, 27, 29, 35, 36, 45, 47, 53, 54, 56, 58, 59, 72, 76, 79, 81, 84, 91, 95, 97, 100, 124, 125, 132, 133, 148, 154, 157, 158, 160, 162, 165, 166, 168, 169, 170, 172, 173, 174, 175, 180. Example 12 Boll Weevil Five adult boll weevils ( Anthonomus grandis ) were placed into each of a series of 9-ounce cups. The test procedure employed was then otherwise the same as in Example 9. Mortality readings were taken 48 hours after treatment. Of the compounds tested on boll weevil, the following resulted in greater than or equal to 80% mortality: 1, 2, 3, 4, 5, 7, 14, 15, 22, 23, 35, 45, 47, 53, 58, 59, 61, 67, 71, 72, 76, 81, 84, 91, 97, 104, 165, 177. Example 13 Aster Leafhopper Test units were prepared from a series of 12-ounce cups, each containing oat ( Avena sativa ) seedlings in a 1-inch layer of sterilized soil. The test units were sprayed as described in Example 9 with individual solutions of the below-listed compounds. After the oats had dried from the spraying, between 10 and 15 adult aster leafhoppers ( Mascrosteles fascifrons ) were aspirated into each of the covered cups. The cups were held at 27°C and 50% relative humidity for 48 hours, after which time mortality readings were taken. Of the compounds tested on aster leafhopper, the following resulted in greater than or equal to 80% mortality: 2, 3, 4, 5, 7, 15, 16, 20, 22, 23, 25, 45, 47, 53, 59, 72, 79, 100, 104, 157, 158, 159, 160, 162, 165, 166, 168, 169, 171, 172, 173, 174, 175, 177, 179, 181. Example 14 Tobacco Budworm The test procedure of Example 9 was repeated on third-instar larvae of the tobacco budworm ( Heliothis virescens ) except that mortality was assessed at 48 hours. Of the compounds tested on tobacco budworm, the following resulted in greater than or equal to 80% mortality: 5, 7, 15, 23, 25, 39, 100, 160, 165, 168, 177. Example 15 Soil Control of Southern Corn Rootworm Test units, each consisting of a three inch cylindrical pot containing 200 grams of moist sassafras loam soil and 2 kernels of Dekalb T1100 corn were prepared. Spraying was accomplished by passing the pots, on a conveyer belt, directly beneath a flat fan hydraulic nozzle which discharged the spray at a rate of 0.25 pounds of active ingredient per acre (about 2 ppm soil concentration) at 30 p.s.i. After the test units had been sprayed, the corn seed was covered with soil and ten third-instar southern corn rootworm larvae ( Diabrotica undecimpunctata howardi ) were added to each unit. Test units were held at 24 degree C, 70% relative humidity and under a photo cycle of 16 hours of light/8 hours of darkness for 7 days, after which time control readings were taken. Control was measured by root injury ratings of 1 to 5, where 1 was no injury and 5 was complete destruction of the root system. Percent of corn seedlings that emerged also was utilized to measure control. The results are tabulated below.
