Miticidal, insecticidal, ovicidal and fungicidal N-(N',N'-diarylaminothio)sulfonamides

BACKGROUND OF THE INVENTION
This invention relates to insecticidal, miticidal, fungicidal and ovicidal sulfonamides, agricultural compositions containing them and methods of using them.
Belgian Pat. No. 826,376, discloses diphenylamine derivatives of the formula: ##STR1## wherein R is hydrogen, C.sub.1-6 alkyl or alkoxy;
X is halogen;
m is zero or an integer from one to three;
n is zero or one;
p is zero, one or two;
q is zero, one or two; and
the sum of m, n, p and q is one, two or three.
Specifically disclosed in U.K. Pat. No. 1,455,207 is the compound 2,5'-bistrifluoromethyl-2'-chloro-4,6-dinitrodiphenylamine. The compounds are taught to have insecticidal, acaricidal and fungicidal properties.
European Patent Office Application 156 discloses 2-anilino-3,5-dinitrobenzotrifluoride derivatives of the formula: ##STR2## wherein R' is alkyl substituted with halogen and/or haloalkoxy; phenyl optionally substituted with halogen, haloalkyl, haloalkoxy, haloalkylmercapto or haloalkylsulphonyl; or, when X=O, R' is unsubstituted alkyl;
R.sup.2 is H, halogen, CN, NO.sub.2 and/or alkyl optionally substituted with halogen and/or haloalkoxy; or XR' and R.sup.2, when ortho to one another, may be linked so as to form (with the 2-adjacent C-atoms of the phenyl ring) an optionally substituted dioxanyl ring.
The application teaches that the disclosed compounds have insecticidal, acaricidal, nematocidal, insect growth retardant, fungicidal and bactericidal activity.

Synthesis
The compounds of this invention, represented by Formula I, can be prepared by the reaction of an anion of the diphenylamine of Formula II with an equivalent or excess of the sulfenyl chloride, ClSZ, in a suitable solvent as illustrated by the following equation: ##STR12##
Aprotic solvents such as tetrahydrofuran (THF), dioxane, methylene chloride, chloroform and toluene are suitable for this reaction. The reaction temperature can be within the range of about -20.degree. C. to 80.degree. C., preferably about -10.degree. C. to 30.degree. C.
The anions of Formula III can be generated by treating compounds of Formula II with an equivalent amount or slight excess of a metal hydride such as sodium hydride or an alkali hydroxide such as potassium hydroxide in a suitable solvent at about -5.degree. C. to 40.degree. C.
Compounds of Formula I can also be prepared by the reaction of diphenylamines of Formula II with a sulfenyl chloride in the presence of an organic tertiary amine acid acceptor such as triethylamine, pyridine and the dialkylanilines, or an inorganic base such as potassium carbonate.
Diphenylamines of Formula II can be obtained by the procedures taught in Belgian Pat. No. 826,376 and European Patent Application 156, the disclosures of which are herein incorporated by reference. The N-chlorothiosulfonamides of the formula ClSZ can also be prepared by a suitable modification, obvious to one skilled in the art, of the procedure taught in British Pat. No. 1,403,170, herein incorporated by reference.
The following examples further illustrate the preparation of compounds of Formula I.

EXAMPLE 1
N-[N-[2-Chloro-5-(trifluoromethyl)phenyl]-N-[2,4-dinitro-6-(trifluoromethyl)phenyl]aminothio]-N,4-dimethylbenzenesulfonamide
To a suspension of 0.25 g sodium hydride in 20 ml anhydrous THF was added 3.2 g of 2-[2'-chloro-5'-(trifluoromethyl)anilino]-3,5-dinitrobenzotrifluoride, in portions, at 10.degree. to 20.degree. C. After stirring for 30 minutes, a solution of 2 g of N-chlorothio-N-methyl-p-toluenesulfonamide in 20 ml dry THF was added rapidly at a temperature below -20.degree. C. The mixture was stirred in an ice bath for 30 minutes, then quenched by careful addition of ether and water. The organic phase was washed once with water, dried over anhydrous magnesium sulfate and filtered. The filtrate was concentrated in vacuo. The resultant oil was crystallized from a mixture of hexane and chlorobutane to give 3.2 g of N-[N-[2-chloro-5-(trifluoromethyl)-phenyl]-N-[2,4-dinitro-6-(trifluoromethyl)phenyl]-aminothio]-N,4-dimethylbenzenesulfonamide, mp 142.5.degree.-144.degree.

Formulation
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 and the like. Many of these may be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from a few pints of several hundred gallons per acre. 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 these ingredients in the following approximate proportions:
______________________________________ Percent by Weight Active In- gredient Diluent(s) Surfactant(s)______________________________________Wettable Powders 20-90 0-74 1-10OilSuspensions, Emulsions,Solutions (including Emul-sifiable Concentrates) 5-50 40-95 0-15Aqueous Suspensions 10-50 40-84 1-20Dusts 1-25 70-99 0-5Granules and Pellets 1-95 5-99 0-15High StrengthCompositions 90-99 0-10 0-2______________________________________
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 by tank mixing.
Typical solid diluents are described in Watkins et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books, Caldwell, N.J. 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.degree. C. "McCutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ridgewood, N.J., as well as Sisely and Wood, "Encyclopedia of Surface Active Agents", Chemical Publishing 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. Pat. No. 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, Dec. 4, 1967, pp. 147 ff. and "Perry's Chemical Engineer's Handbook", 4th Ed., McGraw-Hill, New York (1963), pp. 8-59 ff.

Utility
The compounds of this invention may be used in several ways. First, they may be used to control arthropod pests of plant and animal. These include mites, insects and ticks.
As miticides, they may be used to protect plants from damage caused by these pests. More specifically, fruits, field crops, vegetables and ornamentals can be protected.
When mites come into contact with the compounds of this invention, either in the form of direct sprays or by walking over surfaces which have been treated, they are killed if they have been exposed to a sufficiently high dosage. While most plants are able to tolerate the presence of very small numbers of mites without adverse effect, the reproductive capacity of these pests is enormous. Generally, mite populations rapidly build up, easily out-stripping parasite and predator capabilities for control. Growers noting rapid mite build-up must take immediate action to prevent damage to economically important crops. Thus, there is a need for immediately reducing mite build-up and thereby preventing damage to important crops.
The method of this invention, namely, contacting mites with a miticidally effective concentration, is a most desirable method for control of these pests. This may be accomplished by applying an effective amount of a compound of this invention to the locus of infestation, to the area to be protected or to the pests themselves.
The quantity of compound needed for miticidal activity will vary depending on the specific situation; generally, a very small quantity is required. Among the variables that must be considered in deciding on the quantity of chemical to be used are the specific compound itself, the specific mite to be controlled, weather conditions, the type of crop, the stage of development of the crop, the volume of spray applied, population pressure, and the interval between applications. For plant protection, solutions or suspensions containing as little as 2.5 ppm of active ingredient in a spray solution may prove effective in a given set of circumstances. For field usage, however, in high-volume applications, aqueous spray preparations containing 5-2500 ppm of active ingredient are generally useful. Preferred are suspensions containing 20-500 ppm, and most preferred are those containing 80-320 ppm. On an area basis, in general, 0.03 to 5.5 kilograms of active ingredient per hectare are acceptable, preferably 0.03 to 3 kilograms, and most preferably, 0.06 to 2 kg. When applied in an orchard, spraying is continued until run-off is observed.
The compounds are especially suited for the protection of living plants such as fruit-bearing trees, nut-bearing trees, ornamental trees, forest trees, vegetable crops, horticultural crops (including ornamentals, small fruit and berries) and grain and seed crops. Apple trees, peach trees, cotton, citrus trees, beans and peanuts are particularly susceptible to mite damage and can be protected by application of the compounds of this invention. To assure control throughout the growing season (e.g., June through August in the Northern Hemisphere) multiple applications at desired intervals can be utilized.
Many species of mites are controlled by the compounds of this invention. The following is a list of representative susceptible mites along with the types of damage that they can cause: Panonychus ulmi (European red mite) and Tetranychus urticae (two-spotted mite) which are commonly called "orchard mites," and which attack a great many deciduous trees, such as apple, pear, cherry, plum and peach trees; Tetranychus atlanticus (Atlantic or strawberry mite), T. cinnabarinus (carmine spider mite) and T. pacificus (Pacific mite); which attack cotton and numerous other crop plants; Panonychus citri (citrus red mite) and others which attack citrus; Phyllocoptruta oleivora which causes citrus rust; Byrobia praetiosa (clover mite) which attacks clover, alfalfa and other crops; and Eriophyes erinea which attacks grasses and other plants.
EXAMPLE 8

The compounds of this invention are useful for the control of insects. Both the eggs and the motile forms are susceptible. The insects or insect eggs are controlled by applying the material in a convenient formulation to the locus of infestation, to the area to be protected, or to the pests themselves. For the control of insects in agricultural crops, the compound is generally applied to the foliage or other plant parts which are to be protected. Effective amounts to be applied depend on the species to be controlled, its life stage, its size and location and other variables. In general, 0.1 to 10 kg/ha may be required for insect control in agriculture with rates of 0.25 to 4 kg/ha usually being sufficient. Preferred rates in large scale operations are in the range of 0.3 to 2 kg/ha.
The insect species that may be controlled by ovicidal action of the compounds of this invention include, but are not limited to, Spodoptera exigua (beet armyworm), Spodoptera frugiperda (southern armyworm), Phthorimaea operculella (potato tuberworm), Heliothis zea (cotton bollworm) and Heliothis viresceus (tobacco budworm). These compounds are especially useful for controlling mosquito larvae. Motile stages of insects that may be controlled include, but are not limited to, Anthonomus grandis (cotton boll weevil), Aphis fabae (bean aphid), Myzus persicae (green peach aphid), Epilachna varusestis (Mexican bean beetle) Melanoplus femurrubrum (redlegged grasshopper), and Camponotus pennsylvanicus (black carpenter ant).
EXAMPLE 14

EXAMPLE 16
Twenty-five newly hatched mosquito larvae were placed in 25 ml of distilled water in 4 oz glass jars, and 10 mg diet, consisting of 2 parts liver powder and 1 part brewer's yeast, was added. The test compound, N-[N-(2-chloro-5-(trifluoromethyl)phenyl]-N-[2,4-dinitro-6-(trifluoromethyl)phenyl]aminothio]-N,4-dimethylbenzenesulfonamide, dissolved in 0.2 ml acetone, was added to the jars to give a final concentration of 0.5 ppm. Triplicate runs were made. The jars were capped and held at 27.degree.-30.degree. under continuous light. Additional diet was added to each jar as follows: day 3, 20 mg diet; each succeeding day, a slight sprinkling of diet to replace that eaten. The number of dead insects were recorded daily. The test was terminated when all insects had died or become pupae. The efficacy of the test compound was determined by calculation of the EC.sub.50 value, which is defined as the concentration at which 50% of the initial larvae fail to become adults. The EC.sub.50 for the test compound was found to be 0.00081 ppm.

For the control of anthropod pests of animals, compounds of this invention are generally applied to the locus of infestation, to the area to be protected or to the pests themselves. Effective compounds to be applied depend on the specific compound used, the species to be controlled, its life cycle, its size and location, the amount of rainfall, the time of year, moisture, temperature, type of application and other variables. In general, 0.001% to 10% solutions, dispersions, dusts, etc. may be required for anthropod control in these areas, with rates of 0.05% to 5% solution usually being sufficient in many situations. In efficient large scale operations, rates in the range of 0.01% to 2.5% solution are generally used.
EXAMPLE 21

The compounds of this invention are also useful as plant disease control agents. They are effective for the control of a broad spectrum of plant diseases as represented by, but not limited to, soil-borne fungal pathogens Rhizoctonia solani and Pythuim sp., foliar pathogens, Puccinia graminis, Erisyphe cichoracearum, Venturia inaequalis and Phytophthora infestans, fruit and vegetable rotting fungi, Sclerotinia sclerotiorum and Rhizopus stolonifer and the seedborne fungus Helminthosporium oryzae. Diseases of a wide variety of ornamental, vegetable, cereal and fruit crops are controlled by the compounds of this invention.
Disease control is accomplished by applying the compound to the portion of the plant to be protected, such as the roots, stems, foliage, fruit, seeds, tubers or bulbs, or to the media (soil or sand) in which the plants to be protected are growing. The compound may also be applied to the seed from which the plants to be protected are to be grown.
Rates of application for these compounds will be influenced by many factors of the environment and must be determined under use conditions. Foliage can normally be protected when treated at a rate of from 1 to 500 ppm of active ingredient. Plants growing in soil treated at a concentration of from 0.1 to about 20 kg/ha can be protected from disease. Seed and seedlings can normally be protected when seed is treated at a rate of from 0.06 to about 3 grams per kilogram of seed.
EXAMPLE 22
Rice seed infected with Helminthosporium oryzae are treated with compounds of this invention at a rate of 1.3 g per kilogram of seed. This is accomplished by soaking infected seed for 1 minute in a suspension of the indicated compound dissolved in a solution containing 4% glycerine, 4% water, 0.02% Tween.RTM.20, and 92% acetone. Treated seed are placed on moist blotters and enclosed in plastic bags for 18 days at which time disease ratings are made based on percent germination. As shown in the following table, compounds of this invention provided excellent disease control, as treated seed had a high percentage germination in contrast to untreated seed which did not germinate. Phytotoxicity in the form of growth reduction was observed on germinated seedlings in association with disease control.
