The compounds of this invention can be prepared by reacting a diphenylamine of Formula II with sulfenyl chlorides, ClSZ, in the presence of an acid acceptor and an inert solvent as outlined in the following equation: ##STR13## in which R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, and Z are as previously defined. Organic bases such as N,N-dimethylaniline, triethylamine, trimethylamine, or pyridine or inorganic bases such as sodium or potassium hydroxide sodium or potassium carbonate, or sodium hydride may be used as the acid acceptor. Aprotic solvents such as diethyl ether, tetrahydrofuran (THF), dioxane, methylene chloride, chloroform, or toluene are exemplary of suitable solvents for the reaction. The reaction temperature can be within the range of approximately -40.degree. C. to 80.degree. C., preferably approximately -20.degree. C. to 30.degree. C. Pressure is not critical; for convenience, ambient pressure is preferred.

The diphenylamines of Formula II used in the reactions described above can be prepared using procedures taught in Belgian Pat. No. 826,376, West German Offenlegungsschrift No. 2,823,168, European Patent Application No. 156, and European Patent Application No. 4,642, the disclosures of which are herein incorporated by reference.

The sulfenyl chlorides, ClSZ, used in the preparation of the compounds of Formula I may be prepared by any of several methods well known in the art; such methods have been reviewed in Synthesis, 11, 561-580 (1970) or in Belgian Pat. Nos. 873,911 and 860,894.

The following examples further illustrate the preparation of compounds of Formula I. In the examples, all parts are by weight and temperatures are in degrees Centigrade unless otherwise indicated.

N-isopropyl phosphoramidic acid diethylester (1.95 g) and sulfur dichloride (1.03 g) were dissolved in 25 ml methylene chloride. A solution of 0.95 g of pyridine in 5 ml methylene chloride was added dropwise. The reaction mixture was stirred overnight, cooled, filtered, and solvent was removed from the filtrate in vacuum, leaving an orange-yellow solid. The solid was dissolved in toluene (20 ml) and filtered to give a toluene solution of the sulfenyl chloride.

A 0.58 g quantity of NaH (50% dispersion in mineral oil) was rinsed with hexane and stirred in tetrahydrofuran (THF) under nitrogen. To this slurry was added 4.3 g of N-[2-chloro-5-(trifluoromethyl)phenyl]-2,4-dinitro-6-(trifluoromethyl)benz enamine in portions. The reaction mixture was stirred for 30 minutes and then cooled to -20.degree. C.

The toluene solution of the sulfenyl chloride was added to the THF solution of the diphenylamine sodium salt. The reaction mixture was stirred cold for 1 hour, cooling was removed and the reaction was stirred an additional hour. The reaction mixture was filtered through celite and solvent was removed in vacuum leaving a brown oil. Chromatography on silica gel yielded the desired product as a yellow oil which solidified on trituration with hexanes (m 109.degree.-122.degree. C.). __________________________________________________________________________ ##STR14## __________________________________________________________________________ R.sub.1 R.sub.2 R.sub.3    R.sub.4     R.sub.5    R.sub.6 __________________________________________________________________________ Cl     H       H          CF.sub.3    H          H Cl     H       H          CF.sub.3    H          NO.sub.2 Cl     H             OCF.sub.2 O      H          NO.sub.2 Cl     H       H          CF.sub.3    H          CF.sub.3 Cl     H             OCF.sub.2 OCF.sub.2         NO.sub.2 Cl     H       H          CF.sub.3 O  H          NO.sub.2 Cl     H       H          HCF.sub.2 CF.sub.2 O H          NO.sub.2 Cl     H       H          CH.sub.3 S  H          NO.sub.2 Cl     H       H          CHCl.sub.2 CCl.sub. 2 S H          NO.sub.2 Cl     H       H          CF.sub.3 SO.sub.2 H          NO.sub.2 Cl     H       H          C.sub.2 H.sub.5 S H          NO.sub.2 CF.sub.3 O H       H          Cl          H          NO.sub.2 HCF.sub.2 CF.sub.2 O H       H          Cl          H          NO.sub.2 CHCl.sub.2 CCl.sub.2 S H       H          Cl          H          NO.sub.

Useful formulations of the compounds of Formula (I) can be prepared in conventional ways. They include dusts, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly to the plant. Sprayable formulations can be extended in suitable media and used at spray volumes of from a few pints to 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 1% to 99% solid or liquid diluent(s).

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. Edn., 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. Edn., 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 Co., 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 formulatiosn can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth, promote sticking, 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).

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 1.0 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 6.0% active ingredient.

The compounds of this invention may be used in several ways. First, they are active as miticides and mite ovicides and may be used to protect plants from damage caused by these pests. More specifically, fruits, field crops, vegetables and ornamentals can be protected.

When mite eggs or mites come into contact with the compounds of this invention, either in the form of direct spray or in the case of motile forms by walking over treated surfaces, 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.

The method of this invention, namely, contacting mites or mite eggs with an 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 contain 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 acceptble, 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 fruits and berries) and grain and seed crops. Apple trees, peach trees, cotton, citrus trees, bean 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; Paratetranychus 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 Aceria Neocynodomis which attacks grasses and other plants.

The compounds of this invention are useful for the control of insects throughout their various developmental stages. 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. Preferable rates in large scale operations are in the range of 0.3 to 2 kg/ha.

The insect species that may be controlled during their various developmental stages by the insecticidal action of the compounds of this invention include, but are not limited to, Spodoptera exigua (beet armyworm),

Spodoptera eridania (southern armyworm), Spodoptera frugiperda (fall armyworm), Heliothis zea (bollworm), Heliothis virescens (tobacco budworm), and

Trichoplusia ni (cabbage looper).

These compounds are especially useful for controlling adult mosquitos, mosquito larvae, and ticks including, but not limited to, Rhipicephalus sanguineus (brown dog tick) and Dermacentor variabiles (American dog tick).

Motile stages of insects that may be controlled include, but are not limited to,

Aphis fabae (bean aphid), Myzus persicae (green peach aphid), Melanopus femurrubrum (redlegged grasshopper), and Musca domestica (house fly).

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 pathogen Rhizoctonia solani, foliar pathogens, Puccinia graminis, Erisyphe cichoracearum, Venturia inaequalis and Phytophthora infestans, and the seedborne fungus Helminthosporium oryzae. Diseases of a wide variety of ornamental, vegetable, cereal and fruit crops are controlled by the compound of this invention.

Disease control is accomplished by applying the compounds 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 compounds may also be applied to the seed from which the plants to be protected are to be grown.

Rates of application for the 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.

Rice seed infected with Helminthosporium oryzae are treated with a comound 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, the compound of this invention provided excellent disease control, as treated seed had a high percentage germination in contrast to untreated seed which did not germinate.
