These compounds exhibit excellent insecticidal and arachnicidal activity. Accordingly, the present invention is also concerned with novel methods employing and novel formulations comprising the present compounds for the control of insects and arachnids. Synthesis All of the present fluorinated cycloalkanecarboxanilides are prepared in conventional procedures for the synthesis of carboxanilides. However, a preferred method of synthesis is the reaction of an acyl halide and an aniline, 1-aminonaphthalene, or 2-amino-5-nitropyridine, in accordance with the following scheme: and although other conventional methods are believed to be available, no advantage over the foregoing method is expected. The acyl halide is preferably an acyl fluoride. The acyl fluorides are ob tained directly in the electro-chemical fluorination process by which the fluorinated cycloalkyl (R¹) group is achieved, and thus require no additional reaction prior to their use in preparing the compounds of the present invention. In carrying out the present reaction of acyl fluoride and aniline, 1-aminonaphthalene, or 2-amino-5-nitropyridine, the reactants are conveniently combined in a reaction solvent. Various solvents can be employed, including toluene, acetonitrile, diethyl ether, tetrahydrofuran, and halogenated solvents such as methylene chloride. In general, diethyl ether and halogenated solvents are preferred. A halogenated solvent can sometimes serve as the solvent in a "one-pot" reaction to make the aniline starting material which is thereafter converted to the final product of the invention. In other particulars, the reaction is conventional. An HF acceptor is provided to the reaction mixture; typically triethylamine is used. The reaction consumes the reactants and the HF acceptor in approximately equimolar amounts. The reaction goes forward over a range of temperatures, such as from 10 to 110°C.; however, the reaction is most conveniently carried out at temperatures of from about 20 to 70°C. Workup of the reaction mixture to isolate the product is carried out in conventional procedures. Those compounds of the present invention in which R³ represents methyl are preferably prepared from the corresponding R³=hydrogen compounds. This methylation reaction is carried out in any of the known conventional methods for methylation. Typically, methyl iodide is employed as the reagent, and the reaction is carried out in a suitable solvent, such as acetone, with a base such as potassium carbonate. Equimolar amounts of the reactants are consumed, but the methyl iodide is preferably used in excess. The reaction goes forward over a wide range of temperatures, but is most conveniently carried out at room temperatures of about 25 to 35°C. Workup is by conventional procedures. The present invention also includes salts of the parent compounds. These salts are prepared in entirely conventional methods. The sodium and potassium salts are prepared by reacting the corresponding parent compounds with sodium or potassium hydroxide; the ammonium salts can be obtained by reacting the parent compound with a compound of the formula or by reacting a sodium salt of a present compound with (where X = Br, Cl, or F). The synthesis of the present compounds is further taught by the following illustrative examples. EXAMPLE 1 2'-Bromo-4'-nitro-1,2,2,3,3,4,4,5,5,6,6-undecafluorocyclohexanecar oxanilide. 1,2,2,3,3,4,4,5,5,6,6-Undecafluorocyclohexanecarbonyl fluoride estimated to be of 60% purity (10.9 grams; 0.02 mole) and triethylamine (2 grams; 0.02 mole) were placed in 25 ml of diethyl ether. 2-Bromo-4-nitro-aniline (11.35 grams; 0.02 mole) in 75 ml of diethyl ether was added dropwise at ambient temperature of about 25°C. The reaction mixture was then stirred for 1½ hours. TLC showed no remaining aniline starting material. The reaction mixture was washed with water three times and with dilute sodium bicarbonate solution once, and thereafter dried. The solvent was then removed by evaporation. The product residue was chromatographed on silica gel HPLC with ethyl acetate:hexane 1:5, which yielded 14.5 grams of product containing occluded solvent. It was recrystallized from hexane and air dried, yielding 5.0 grams (48%) of purified product melting at 98-101°C. An additional 1 gram was obtained from the mother liquor for a total yield of 57%.

Thus, the compounds, while they can be employed alone, are preferably formulated with conventional adjuvants, as described in more detail in the section below concerning Formulations. The amount of the present compounds which will provide insecticidal and/or arachnicidal activity is not critical and will vary widely, depending on the locus (foliage, soil, etc.), the susceptibility of the particular insect or arachnid, the level of activity of the particular compound chosen, weather and soil conditions, and the like. In general, when employing the compounds in spray formulations to be applied to foliage, concentrations of from 1 to 5000 ppm are efficacious. Lower concentrations of from 1 to 1000 ppm, and even from 1 to 100 ppm, often suffice. In the case of application to soil to control soil-dwelling organisms, concentrations in the soil of from 1 ppm or less to as much as 50 ppm provide good activity With the more active members of the series, lesser concentrations of from 1 to 10 ppm provide good activity. The compound of Example 1, as shown by the above examples, will provide control in the field at application rates of approximately 0.1 lb/acre (0.112 ka/ha) to 1.0 lb/acre (1.12 kg/ha). The compounds to be employed in accordance with the present invention can be applied by standard agricultural equipment and techniques. However, the compounds exhibit some phytotoxicity, and this fact should be taken into account in selecting an application technique. For application to soil to control soil-dwelling organisms, it is preferred that the compounds be applied in a technique by which a pesticide is prevented from contacting the seeds, for example, post presswheel placement. Preferred Embodiments A preferred embodiment of the present invention is the use of selected compounds for the control of corn rootworm. Those compounds exhibiting good activity against corn rootworm will be apparent from Table XIII above. Among the compounds of the present invention, there are various preferences: (1) a preference for R¹ = fluorocyclohexyl as defined, (2) a preference for n = p = q = 0 or 1, (3) a preference for R³ = hydrogen, (4) a preference for R⁴ = substituted aryl as defined, and especially for the following substituted aryl groups: (a) 2,4(or 2,5)-disubstituted phenyl of the formula wherein R¹⁰ = fluoro, chloro, bromo, iodo, cyano, methyl, trifluoromethyl, or nitro; (b) 2,4-disubstituted phenyl of the formula wherein R¹¹ = cyano or trifluoromethyl and R¹² = bromo or chloro; (c) 2,4,5(or 2,4,6)-trisubstituted phenyl of the formula wherein R¹³ = bromo, chloro, or methyl; (d) 2,3,4,5-tetrachlorophenyl; and (e) pentafluorophenyl. Among the salts of the present invention, it has been found that the ammonium salts are preferred, and among the ammonium salts, the following particular salts are especially advantageous: hexadecyltrimethylammonium, octadecyltrimethylammonium, tributylammonium, tris(2-hydroxethyl)ammonium, tris(2 or 3-hydroxypropyl)ammonium, and dimethylbis(C₁₀-C₁₈)ammonium. Herbicidal Activity In addition to exhibiting activity against insects and arachnids, the present compounds also exhibit some herbicidal activity. In general, the herbicidal activity is expressed at rates higher than those at which insecticidal and arachnicidal activity is exhibited. Therefore, the preferred insecticidal/arachnicidal utility of the present invention can generally be practiced with minimal or no phytotoxicity. Representative co mpounds of the present invention were evaluated for herbicidal efficacy in standard screening tests. In these tests, each compound was evaluated against a number of crop and weed species, for both preemergent and postemergent effect. Many of the compounds of the present invention exhibit herbicidal activity at rates of from 0.05 to 8 lbs/acre. Therefore, in another embodiment, the present invention is directed to a method for inhibiting the growth of a plant which comprises applying to the plant an effective amount of a compound of the present invention. The compounds can be applied pre-emergently for the control of germinating seeds or post-emergently for the control of existing vegetation. The compounds are preferably formulated as described below. Other Utilities Compounds of the present invention have also exhibited nematocidal, fungicidal, anthelmintic, and ectoparasiticidal activity. By appropriate selection of rates and methods of application, therefore, the present compounds can be employed for these other utilities. For all of these uses, the compounds are employed in conventional manners. For example, the compound of Example 1 is effective in controlling various pathogenic nematode species, while having little effect on the benign Saprophagous nematodes. Thus, in another embodiment of the present invention, the compound of Example 1 or a salt thereof is applied to nematode infested soil in an effective, nematocidal amount. The method is practiced in accordance with standard techniques for the application of nematocides. In general, good nematocidal activity can be expected at rates of 1-10 lbs/acre. The compound can be formulated as described below in the Formulations section; in general, granular formulations are preferred. Fungicidal Activity Many of the compounds of the present invention exhibit useful fungicidal activity. Accordingly, in another embodiment, the present invention is directed to a method of inhibiting a plant pathogenic fungal organism which comprises applying to a locus of the organism an inhibiting amount of a compound of the present invention. The method is practiced in accordance with standard techniques for the use of fungicides. The compounds can be formulated as described below in the Formulations section. In general, good fungicidal efficacy can be expected at rates of 0.5-5.0 lbs/acre. Preferred for this embodiment are compounds of four subgenera. A first subgenus is defined by the formula and includes salts thereof, as defined above. In the foregoing formula, each X represents halo (i.e., bromo, chloro, fluoro, or iodo), which is independently selected except that no more than one X can represent iodo. This subgenus is exemplified by Examples 57, 60, 106, 124, 133, 134, and 135. A second group of compounds, also a subgenus of the generic scope described above, is of the following formula and includes salts thereof, as defined above. In the foregoing formula, T represents fluoro, C₁-C₄ alkoxy, or C₁-C₄ alkylthio, located at either the 3- or 5-position. This group of compounds is exemplified by Examples 55, 128, 129, and 138. A third group of compounds preferred for antifungal use is again a subgenus of the compounds generically described above. This group is defined by the following formula and includes salts thereof, as defined above. In the foregoing formula, Y represents halo, nitro, or methyl, and Z represents nitro or fluorosulfonyl. This group of compounds is exemplified by Examples 5, 8, 11, 29, 113, 118, and 126. The fourth preferred group consists of compounds of formula (I) wherein R⁴ is phenyl substituted with two groups, including a thiocyanato group and a nitro, R⁵ or iodo group. This group of compounds is illustrated by Example 147. Formulations For any of their various uses, the compounds of the present invention are preferably formulated with a suitable agriculturally acceptable carrier. Typically such a formulation will contain from about 0.05 to about 95.0 percent by weight of the active ingredient. Examples of such compositions include sprayable formulations, such as wettable powders, aqueous suspensions and emulsifiable concentrates; and solid compositions, such as dusts, granules, and dry-flowable pellets. The compounds can also be formulated with fertilizer and applied to soil to achieve both an effect in accordance with the present invention as well as fertilization of the crop. Sprayable formulations are in the form of concentrated compositions which can be diluted with water to form water dispersions or emulsions containing in the range from about 0.05 percent to about 10 percent of the active agent by weight. Such water dis persions or emulsions are sprayed onto plants or onto soil. The concentrated compositions may be either solids, usually known as wettable powders or dry flowables, or liquids, usually known as emulsifiable concentrates and aqueous suspensions. A typical wettable powder comprises an intimate mixture of an active ingredient of the invention, an inert carrier, and surfactants. The concentration of the active agent is usually from about 25 percent to about 90 percent by weight. The inert carrier is usually chosen from among the attapulgite clays, the montmorillonite clays, the diatomaceous earths, the kaolinites, or the purified silicates. Effective surfactants, comprising from about 0.5 percent to about 10 percent by weight of the wettable powder, are chosen from among the condensed naphthalenesulfonates, the alkyl sulfates and the alkyl arylethoxylates. Suspending agents, such as the sulfonated lignins can also be added. A typical emulsifiable concentrate comprises from about 0.1 to about 6 pounds (from about 0.045 kg to about 3.05 kg) of a compound of the invention per gallon of liquid, dissolved in a mixture of organic solvents and emulsifiers. The organic solvent is chosen with regard to its solvency and its cost. Useful solvents include the aromatics, especially the xylenes and the heavy aromatic naphthas. Hydrophilic cosolvents such as DMF, cyclohexanone, and the glycol ethers such as 2-methoxyethanol may be included. Other organic solvents may also be used, including the terpenic solvents and kerosene; methyl heptyl ketone and other high molecular weight ketones; cyclohexyl acetate and other high molecular weight esters. Suitable emulsifiers for emulsifiable concentrates are chosen from the alkylbenzenesulfonates, naphthalenesulfonates, and nonionic surfactants such as alkylphenol adducts of polyoxyethylene, and are used at similar percentages as for wettable powders. An aqueous suspension, or flowable, is comprised of a finely ground suspension of the active ingredient dispersed in a water based system. This type of formulation is particularly useful for compounds with low water solubility. The concentration of active agent is usually from about 15 to 60 percent by weight. A typical aqueous suspension may comprise wetting and dispersing agents, antifreeze components, thickening or bulking agents, as well as water and the active ingredient. Dust compositions containing a compound of the present invention usually contain from about 0.1 to about 50 percent by weight of the compound. Dusts are prepared by intimately mixing and finely grinding the active agent with an inert solid such as ground montmorillonite clay, attapulgite clay, talc, ground volcanic rock, kaolin clay, or other inert, relatively dense, inexpensive substances. Solid, granular compositions are convenient for the application of compounds of this invention to the soil and will contain the active agent in an amount from about 0.1 to about 25 percent by weight. Granules comprise a compound of the invention dispersed on a granular inert carri er such as coarsely ground clay of from about 0.1 to about 3 mm particle size. The active ingredient is most conveniently applied to the clay by dissolving it in an inexpensive solvent, such as acetone, methylene chloride, xylene or other petroleum solvents, methoxy propylene glycol, or the like, and applying the solution to the sized clay in an appropriate solids mixer. The solvent is then typically removed by evaporation; however removal is not essential. Alternatively, any of the present compounds which is an oil can be sprayed, with or without heating, directly onto clay. Likewise, any of the present compounds which is a solid can be melted and then sprayed directly onto clay. Numerous representative formulations of the compounds to be employed in accordance with the present invention were prepared. Examples follow. EXAMPLE A Emulsifiable Concentrate A 1 lb/gallon emulsifiable concentrate was prepared by dissolving the compound of Example 1, estimated to be of 97% purity, in xylene and adding Toximul H and Toximul D (each of Toximul H and Toximul D is a sulfonate-nonionic blend of emulsifiers produced by Stepan Chemical Co.) EXAMPLE B Wettable Powder A 20% wettable powder of the compound of Example 1 was prepared by mixing the first five listed ingredients in conventional fashion. After these ingredients had been mixed, 3% of Selogen HR (a dispersing agent produced by Diamond Shamrock) and 3% of a mixture of (1) 22% of TMN-6, a surfactant sold by Union Carbide, trimethylnonane/6 moles of ethylene oxide, (2) 28% of Triton X-100, a surfactant sold by Rohm & Haas, octylphenol/10 moles of ethylene oxide, and (3) 50% of HiSil, a lightweight silica sold by Pittsburg Plate Glass Co. were added and blended until uniform. The ingredients and the % of each in the final formulation were as follows. EXAMPLES C-F 1%-10% Granules A series of four granular formulations of the compound of Example 1 was prepared. In each instance, the appropriate amount of the compound was dissolved in acetone, at the rate of 1 gram of compound per 2 grams of acetone, and the resulting solution was sprayed onto clay under agitation. Thereafter, the acetone was evaporated to provide the final formulation. The clay employed in this series of granular formulations was 30/60 mesh Florex RVM (RVM = regular volatile material), an attapulgite clay produced by the Floridin Co. The compound of Example 1 was estimated to be of 97% purity. The specific granular formulations so produced, each in 50-gram quantity, were as follows. EXAMPLE G 20% Granule A 20% granular formulation of the compound of Example 1 was also prepared. The preparation was the same as described in the immediately preceding series, except that the compound was dissolved in acetone, 1.5 grams of acetone per gram of compound of Example 1. Propylene glycol was then added to the solution, and the acetone was removed by evaporation as in prior examples. The compound of Example 1 which was used in this formulation was estimated to be of 98% purity. The final formulation, in the amount of 105 grams, was as follows. EXAMPLE H 2% Granule A 2% granular formulation of the compound of Example 1 was also prepared. Again, the procedure used was as reported above. However, 2.5 grams of acetone were employed in dissolving each gram of the compound of Example 1. The compound of Example 1 employed in this formulation was estimated to be of 95% purity. The resulting formulation, in the amount of 19.1 kg, was as follows. EXAMPLE I 2% ule Another 2% granular formulation of the compound of Example 1 was prepared, in the same procedure except that 4 grams of acetone were used in dissolving each gram of the compound of Example 1; the estimated purity of the compound of Example 1 was 97%; and the clay employed was 24/48 mesh Florex, also produced by the Floridin Co. EXAMPLE J 10% Granule A 10% granular formulation of the compound of Example 1 was prepared as for the last-described granule, except that the clay employed in this formulation was Oil-Dri 30/40 mesh Mississippi Grey clay RVM (RVM = regular volatile material). The compound of Example 1 which was employed in this formulation was estimated to be of 95% purity. The final formulation, in the amount of 4.5 kg, was as follows. EXAMPLE K 10% Granule A granular formulation of the compound of Example 1 was also prepared employing plaster of paris as the carrier. Compound of Example 1 was ground in a mortar and pestle with plaster of paris. Water was then added to make a paste, which was spread thinly over a flat surface, allowed to harden, and broken up into small pieces and sieved, 24/48 "Tyler" mesh. The final formulation was as follows. EXAMPLE L 10% Granule Another granular formulation was prepared in accordance with the foregoing procedures, except that the active ingredient was the compound of Example 77, in estimated purity of 100%. The final formulation was as follows. EXAMPLE M 10% Granule on various carriers A series of granular formulations of the compound of Example 85 was prepared. In each instance, the compound, estimated to be of 100% purity, was dissolved in dichloromethane, yielding a 20% solution of the compound of Example 85. A portion of this solution was poured onto each of numerous carriers, mixed well, and air dried to remove the dichloromethane. All of the resulting formulations had the same composition, as follows. The carriers utilized in these formulations, and their sources, were as follows: Oil-Dri Mississippi Grey clay (this same clay is also referred to as Agsorb RVM-MS); Oil-Dri Mississippi Brown clay (this same clay is also referred to as Agsorb LVM-MS); Oil-Dri Georgia white clay - Oil-Dri Corporation Florex RVM; Florex LVM - Floridin Company (LVM = low volatile material) Agsorb LVM - Oil-Dry Corporation Attapulgus RVM - Engelhardt Minerals Bentonite Granular - American Colloid Pike's Peak clay (9-J) - General Reduction Corp. KWK Volclay - American Colloid Lowe's Oran, Missouri clay; Lowe's Bloomfield, Missouri clay - Lowe's Industrial Products, Inc. Based on this study, Oil-Dri Mississippi Grey Clay and Oil-Dri Mississippi Brown Clay are regarded as the preferred carriers for the parent compounds. For salts, Florex LVM clay and Lowe's Oran, Missouri clay are preferred. In view of the fact that the compounds of the present invention exhibit some herbicidal activity, it may be useful to formulate the compounds for insecticidal use in slow-release forms. For example, in using the compounds for the control of corn rootworm, maximum protection against the rootworm is not needed upon germination of the corn seed, but rather several weeks later. Delaying the release of the compound will prevent damage to the germinating corn seedling, while still providing effective control of the corn rootworm at the time it becomes a threat to the corn seedling. EXAMPLE N 10% Slow Release Granule A representative slow-release formulation was prepared by dissolving the compound of Example 1, estimated purity of 97%, in a cetone at the rate of 1 gram of compound per 4 grams of acetone. The resulting solution was applied to granules of Oil-Dri Mississippi Grey clay, 30/40 mesh, and the acetone was then evaporated off. The granules were then treated with a solution of 5 parts of Carboset 525 (a polyacrylic acid sold by B.F. Goodrich) in 225 parts of a dilute solution of ammonium hydroxide. The treatment consisted of pouring a sixth of the Carboset solution over the granules, mixing well, and drying in a fluid bed drier; the procedure was repeated until all of the Carboset solution had been applied to the granules. The final formulation was as follows. EXAMPLE O 10% Slow Release Granule A 10% slow release granule was made employing the compound of Example 1, Carboset 525, and Florex 20/30 mesh RVM clay. A solution of NaOH was added to another portion of the Carboset 525/NH₄OH solution described in the preceding example, and mixed well. Thereafter, compound of Example 1 was dissolved in acetone and added to the Carboset 525/NaOH solution. The resulting solution was again mixed well. The solution was then added portionwise to the carrier, by adding one-third of the solution, mixing well and drying, then repeating these steps with the remaining portions. The resulting granule was screened through 20 and 30 mesh screens, and had the following composition. EXAMPLE P 2% Slow Release Granule Four slow release formulations were prepared employing cellulose acetate. The compound of Example 1 was dissolved in acetone and the cellulose acetate was added. The solution was poured over the carrier, mixed well, and air dried. The resulting formulations were as follows. The carriers employed in these formulations were the following Agsorb 30/60 LVM Attapulgus 30/60 RVM Florex 30/60 RVM Oil-Dri Mississippi Grey Clay, 30/60 RVM EXAMPLE Q Emulsifiable Concentrate A 1 lb/gallon emulsifiable concentrate was prepared by dissolving the compound of Example 144, estimated to be of 99% purity, in Panasol AN3N and adding Toximul D. EXAMPLE R Another 1 lb/gallon emulsifiable concentrate was prepared by dissolving the compound of Example 1 in Panasol AN3N and adding other ingredients. The final formulation was as follows: EXAMPLE S Yet another 20% wettable powder was prepared with the following composition. Starting Materials As taught above, the compounds of the present invention are prepared by the reaction of an acyl halide and an aniline, 1-aminonaphthalene, or 2-amino-5-nitropyridine: These starting materials are either known compounds or are prepared in known procedures. Essentially all of the anilines are known compounds. 1-Aminonaphthalene and 2-amino-5-nitropyridine are likewise known compounds. Among the acyl halide starting materials, those wherein R¹ is perfluorocyclopropyl, perfluorocyclobutyl, perfluorocyclopentyl, and perfluorocyclohexyl with no substituents, are known. The remaining acyl halides are prepared in known procedures. Typically, a substituted benzoyl halide or benzoic acid or a naphthoic acid halide or acid is electrochemically fluorinated to the desired starting material. Because this process results in fluorination of all replaceable groups, a substituent on a benzoyl halide or benzoic acid will be converted to a fluorinated substitutent. Conversion of such substituent groups in the process of electrochemical fluorination is known, as follows: A general reference on electrochemical fluorination is "Chemistry of O rganic Fluorine Compounds" by M. Hudlicky (Horwood Ltd., 1976), especially page 73. However, as an exception to the foregoing, those starting acyl fluorides which bear a chlorine substitutent require a chlorine-substituted benzoic acid or acid halide, inasmuch as chlorine can survive replacement in the course of electrochemical fluorination. As another exception, it is entirely possible to conduct electrochemical fluorination on a fluorinated or partially fluorinated benzoyl halide. Although the same perfluorinated cyclohexane acyl fluoride is obtained as when beginning with a non -fluorinated benzoyl halide, product yields have sometimes been higher. For example, the acyl fluoride starting material to be employed in Example 140, 4-(trifluoromethoxy)-1,2,2,3,3,4,5,5,6,6-decafluorocyclohexanoyl fluoride, is preferably prepared by electrochemical fluorination of a 4-(trifluoromethoxy)benzoyl halide. Finally, electrochemical fluorination can also be carried out on any of the cycloalkanecarboxylic acids and acid halides, yielding the corresponding perfluorinated cycloalkane acid fluoride. Electrochemical fluorination of benzoyl halides may result in some rearrangement to isomers which are CF₃-substituted, cyclopentane acyl fluorides. Because anilides made from these fluorides share the activity of the present invention, there is no need to remove the rearranged isomers. Also note Example 110, above.
