Fungicidal aniline derivatives
This is a continuation-in-part application of our copending application Ser. No. 485,295 filed on Apr. 15, 1983. 
    
    
     This invention relates to fungicidal aniline derivatives. 
     Benzimidazole and thiophanate fungicides such as Benomyl (methyl 1-(butylcarbamoyl)benzimidazol-2-ylcarbamate), Fubelidazol (2-(2-furyl)benzimidazole), Thiabendazole (2-(4-thiazolyl)benzimidazole), Carbendazim (methyl benzimidazol-2-ylcarbamate), Thiophanate-methyl (1,2-bis(3-methoxycarbonyl-2-thioureido)benzene), Thiophanate (1,2-bis(3-ethoxycarbonyl-2-thioureido)benzene), 2-(O,S-dimethylphosphorylamino)-1-(3&#39;-methoxycarbonyl-2&#39;-thioureido)benzene and 2-(O,O-dimethylthiophosphorylamino)-1-(3&#39;-methoxycarbonyl-2&#39;-thioureido)benzene are known to show an excellent fungicidal activity against various plant pathogenic fungi, and they have been widely used as agricultural fungicides since 1970. However, their continuous application over a long period of time provides phytopathogenic fungi with tolerance to them, whereby their plant disease-preventive effect is much lowered. Further, the fungi which gained tolerance to certain kinds of benzimidazole or thiophanate fungicides also show considerable tolerance to some other kinds of benzimidazole or thiophanate fungicides. Thus, they are apt to obtain cross-tolerance. Therefore, if any material decrease of their plant disease-preventive effect in certain fields is observed, their application to such fields has to be discontinued. But, it is often observed that the density of drug-resistant organisms is not decreased even long after the discontinuation of the application. Although other kinds of fungicides have to be employed in such case, only few are so effective as benzimidazole or thiophanate fungicides in controlling various phytopathogenic fungi. Cyclic imide fungicides such as Procymidone (3-(3&#39;, 5&#39;-dichlorophenyl)-1,2-dimethylcyclopropane-1,2-dicarboximide), Iprodione (3-(3&#39;, 5&#39;-dichlorophenyl)-1-isopropylcarbamoylimidazolidine-2,4-dione), Vinchlozolin (3-(3&#39;, 5&#39;-(dichlorophenyl)-5-methyl-5-vinyloxazolidine-2,4-dione), ethyl (RS)-3-(3&#39;, 5&#39;-dichlorophenyl)-5-methyl-2,4-dioxooxazolidine-5-carboxylate, etc., which are effective against various plant diseases, particularly those caused by Botrytis cinerea, have the same defects as previously explained with respect to the benzimidazole and thiophanate fungicides. 
     In C.R. Acad. Sc. Paris, t. 289, S&#39;erie D, pages 691-693 (1979), it is described that such herbicides as Barban (4-chloro-2-butynyl N-(3-chlorophenyl)carbamate), Chlorobufam (1-methyl-2-propynyl N-(3-chlorophenyl)carbamate), Chlorpropham (isopropyl N-(3-chlorophenyl)carbamate) and Propham (isopropyl N-phenylcarbamate) exhibit a fungicidal activity against certain organisms tolerant to some of the benzimidazole or thiophanate fungicides. However, their fungicidal activity against the drug-resistant fungi is not strong enough, and hence, practically they can not be used as fungicides. 
     As a result of a study seeking a new type of fungicides, it has now been found that aniline derivatives of the formula: ##STR2## wherein X and Y are, the same or different, each a hydrogen 
     a halogen atom, a lower alkyl group, a halo(lower)-alkyl group, a lower alkenyl group, a lower alkynyl group, a cyano group, a hydroxyiminomethyl group, a lower alkoxy-iminomethyl group or a group of the formula: --CH 2  OR 2 , ##STR3## in which R 2  is a lower alkyl group, R 3  is a lower alkyl group, a lower alkenyl group or a lower alkynyl group and R 4  is a lower alkylene group, with the proviso that when either one of X and Y is a hydrogen atom, the other is not a hydrogen atom; R 1  is a halo(lower)alkenyl group, a halo(lower)alkynyl group, a cyano group, a hydroxy(lower)alkyl group, a lower alkoxy(lower)alkenyl group, a lower alkoxy(lower)alkynyl group, a cyano(lower)alkyl group or a group of the formula: --CH 2  R 5 , ##STR4## or --SO 2  R 7  in which R 5  is a lower alkoxy-carbonyl group, an acyl group (e.g. lower alkanoyl, benzoyl) or a lower alkylthio group, R 6  is a lower alkyl group, a lower alkoxy group or a lower alkylamino group and R 7  is a lower alkyl group, a halo(lower)alkyl group or a lower alkylamino group; Z is a hydrogen atom, a hydroxyl group, a lower alkoxy group, a lower alkyl group, a lower alkenyl group, a lower alkynyl group, a lower alkoxycarbonyl-(lower) alkyl group, a lower alkoxycarbonyloxy group, a lower alkylcarbonyloxy group or a group of the formula: ##STR5## or --SR 9  in which R 8  is a lower alkyl group, a cyclo(lower)-alkyl group, a halo(lower)alkyl group, a lower alkoxyalkyl group or a phenyl group and R 9  is a lower alkyl group, a lower alkoxycarbonyl group or a phenyl group; A is an oxygen atom or a sulfur atom; and B is a lower alkyl group, a lower alkenyl group, a cyclo(lower)alkyl group, a phenyl group or a group of the formula: -W-R 10  in which W is an oxygen atom or a sulfur atom and R 10  is a cyclo(lower)alkyl group, a lower alkyl group, a lower alkenyl group, a lower alkynyl group, a halo(lower)alkenyl group, a halo(lower)alkynyl group, a phenyl group, a phenyl group substituted with a halogen atom, a cyclo(lower)alkyl(lower)alkyl group or a lower alkyl group substituted with a member selected from the group consisting of halogen, cyano, lower alkoxy, phenyl, lower alkenyloxy, halo(lower)alkoxy, phenoxy and ar(lower)alkoxy (e.g. phenyl(lower)alkoxy), show an excellent fungicidal activity against plant pathogenic fungi which have developed resistance to benzimidazole, thiophanate and/or cyclic imide fungicides. It is notable that their fungicidal potency against the organisms tolerant to benzimidazole, thiophanate and/or cyclic imide fungicides (hereinafter referred to as &#34;drug-resistant fungi&#34; or &#34;drug-resistant strains&#34;) is much higher than that against the organisms sensitive to benzimidazole, thiophanate and/or cyclic imide fungicides (hereinafter referred to as &#34;drug-sensitive fungi&#34; or &#34;drug-sensitive strains&#34;). 
     The term &#34;lower&#34; used hereinabove and hereinafter in connection with alkyl, alkenyl, alkynyl, alkylene, alkoxy, etc. is intended to have not more than 6 carbon atoms. 
     Among the compounds of the formula (I), 3,5-dichloro-4-cyanooxymethacrylanilide and 3-methyl-4-cyanooxymethacrylanilide (Belgian Pat.

The resultant solution was washed with water, dried over magnesium sulfate and concentrated under reduced pressure to give isopropyl N-(3-methoxy-4-cyanomethoxy-5-methoxyiminomethylphenyl)carbamate (Compound No. 78) (0.62 g) in a yield of 94.5%.

     In the practical usage of the compounds of the formula (I) as fungicides, they may be applied as such or in a formulation form such as dusts, wettable powders, oil sprays, emulsifiable concentrates, tablets, granules, fine granules, aerosols or flowables. Such formulation form can be formulated in a conventional manner by mixing at least one of the compounds of the formula (I) with an appropriate solid or liquid carrier(s) or diluent(s) and, if necessary, an appropriate adjuvant(s) (e.g. surfactants, adherents, dispersants, stabilizers) for improving the dispersibility and other properties of the active ingredient. 
     Examples of the solid carriers or diluents are botanical materials (e.g. flour, tobacco stalk powder, soybean powder, walnut-shell powder, vegetable powder, saw dust, bran, bark powder, cellulose powder, vegetable extract residue), fibrous materials (e.g. paper, corrugated cardboard, old rags), synthetic plastic powders, clays (e.g. kaolin, bentonite, fuller&#39;s earth), talcs, other inorganic materials (e.g. pyrophyllite, sericite, pumice, sulfur powder, active carbon) and chemical fertilizers (e.g. ammonium sulfate, ammonium phosphate, ammonium nitrate, urea, ammonium chloride). 
     Examples of the liquid carriers or diluents are water, alcohols (e.g. methanol, ethanol), ketones (e.g. acetone, methylethylketone), ethers (e.g. diethyl ether, dioxane, cellosolve, tetrahydrofuran), aromatic hydrocarbons (e.g. benzene, toluene, xylene, methyl naphthalene), aliphatic hydrocarbons (e.g. gasoline, kerosene, lamp oil), esters, nitriles, acid amides (e.g. dimethylformamide, dimethylacetamide), halogenated hydrocarbons (e.g. dichloroethane, carbon tetrachloride), etc. 
     Examples of the surfactants are alkyl sulfuric esters, alkyl sulfonates, alkylaryl sulfonates, polyethylene glycol ethers, polyhydric alcohol esters, etc. Examples of the adherents and dispersants may include casein, gelatin, starch powder, carboxymethyl cellulose, gum arabic, alginic acid, lignin, bentonite, molasses, polyvinyl alcohol, pine oil and agar. As the stabilizers, there may be used PAP (isopropyl acid phosphate mixture), tricresyl phosphate (TCP), tolu oil, epoxydized oil, various surfactants, various fatty acids and their esters, etc. 
     The foregoing formulations generally contain at least one of the compounds of the formula (I) in a concentration of about 1 to 95% by weight, preferably of 2.0 to 80% by weight. By using the formulations, the compounds of the formula (I) are generally applied in such amounts as 2 to 100 g per 10 are. 
     When only the drug-resistant strains of phytopathogenic fungi are present, the compounds of the formula (I) may be used alone. However, when the drug-sensitive strains are present together with the drug-resistant strains, their alternate use with benzimidazole, thiophanate and/or cyclic imide fungicides or their combined use with benzimidazole, thiophanate and/or cyclic imide fungicides is favorable. In such alternate or combined use, each active ingredient may be employed as such or in conventional agricultural formulation forms. In case of the combined use, the weight proportion of the compound of the formula (I) and the benzimidazole, thiophanate and/or cyclic imide fungicide may be from about 1:0.1 to 1:10.0. 
     Typical exmaples of the benzimidazole, thiophanate and cyclic imide fungicides are shown in Table 2.

     EXPERIMENT 1 
     Protective activity test on powdery mildew of cucumber (Sphaerotheca fuliginea): 
     A flower pot of 90 ml volume was filed with sandy soil, and seeds of cucumber (var: Sagami-hanjiro) were sowed therein. Cultivation was carried out in a greenhouse for 8 days. Onto the resulting seedlings having cotyledons, the test compound formulated in an emulsifiable concentrate or wettable powder and diluted with water was sprayed at a rate of 10 ml per pot. Then, the seedlings were inoculated with a spore suspension of the drug-resistant or drug-sensitive strain of Sphaerotheca fuliginea by spraying and further cultivated in the greenhouse. Ten days thereafter, the infectious state of the plants was observed. The degree of damage was determined in the following manner, and the results are shown in Table 3. 
     The leaves examined were measured for a percentage of infected area and classified into the corresponding disease indices, 0, 0.5, 1, 2, 4:

     As understood from the results shown in Table 5, the compounds of the formula (I) of the invention show an excellent preventive effect on the drug-resistant strain but do not show any preventive effect on the tested drug-sensitive strain. To the contrary, commercially available known fungicides such as Benomyl and Thiophanate-methyl show a notable controlling effect on the drug-sensitive strain but not on the drug-resistant strain. 
     Experiment 4 
     Preventive effect on brown leaf-spot of peanut (Cerospora arachidicola): 
     Plastic pots of 90 ml volume were filled with sandy soil, and seeds of peanut (var:Chiba hanryusei) were sowed therein. Cultivation was carried out in a greenhouse for 14 days. Onto the resulting seedling, the test compound formulated in an emulsifiable concentrate or wettable powder and diluted with water was sprayed at a rate of 10 ml per pot. Then, the seedlings were inoculated with a spore suspension of the drug-resistant or drug-sensitive strain of Cercospora arachidicola by spraying. The resulting plants were covered with a polyvinyl chloride sheet to make a condition of humidity and cultivated in the greenhouse for 10 days. The degree of damage was determined in the same manner as in Experiment 1, and the results are shown in Table 6.

     Experiment 5 
     Preventive effect on gray mold of cucumber (Botrytis cinerea): 
     Plastic pots of 90 ml volume was filled with sandy soil, and seeds of cucumber (var:Sagami-hanjiro) was sowed therein. Cultivation was carried out in a greenhouse for 8 days to obtain cucumber seedlings expanding cotyledons. Onto the resulting seedlings, the test compound formulated in an emulsifiable concentrate or wettable powder and diluted with water was sprayed at a rate of 10 ml per pot. After air-drying, the seedlings were inoculated with mycelial disks (5 mm in diameter) of the drug-resistant or drug-sensitive strain of Botrytis cinerea by putting them on the leaf surfaces. After the plants were infected by incubating under high humidity at 20° C. for 3 days, the rates of disease severity were observed. The degree of damage was determined in the same manner as in Experiment 1, and the results are shown in Table 7.

     Experiment 6 
     Preventive effect on gummy stem blight of cucumber (Mycosphaerella melonis): 
     Plastic pots of 90 ml volume were filled with sandy soil, and seeds of cucumber (var:Sagami-hanjiro) were sowed therein. Cultivation was carried out in a greenhouse for 8 days to obtain cucumber seedlings expanding cotyledons. Onto the resulting seedlings, the test compound formulated in an emulsifiable concentrate or wettable powder and diluted with water was sprayed at a rate of 10 ml per pot. After air-drying, the seedlings were inoculated with mycelial disks (5 mm in diameter) of the drug-resistant or drug-sensitive strain of Mycosphaerella melonis by putting them on the leaf surfaces. After the plants were infected by incubating under high humidity at 25° C. for 4 days, the rates of disease severity were observed. The degree of damage was determined in the same manner as in Experiment 1, and the results are shown in Table 8.

     Preventive effect on powdery mildew of cucumber (Sphaerotheca fuliginea): 
     A plastic pot of 90 ml volume was filled with sandy soil, and seeds of cucumber (var:Sagami-hanjiro) were sowed therein. Cultivation was carried out in a greenhouse for 8 days. Onto the resulting seedlings having cotyledons, the test compound(s) formulated in an emulsifiable concentrate or wettable powder and diluted with water were sprayed at a rate of 10 ml per pot. Then, the seedlings were inoculated with a mixed spore suspension of the drug-resistant and drug-sensitive strain of Sphaerotheca fuliginea by spraying and further cultivated in the greenhouse. Ten days thereafter, the infectious state of the plants was observed. The degree of damage was determined in the same manner as in Experiment 1, and the results are shown in Table 11.

     As understood from the results shown in Table 11, the combinated use of the compounds of the formula (I) of the invention with benzimidazole, thiophanate and/or cyclic imide fungicides show much more excellent preventive effect than their sole use. 
     Experiment 10 
     Preventive effect on gray mold of tomato (Botrytis cinerea): 
     A plastic pot of 90 ml volume was filled with sandy soil, and seeds of tomato (var:Fukuju No. 2) were sowed therein. Cultivation was carried out in a greenhouse for 4 weeks. Onto the resulting seedlings at the 4-leaf stage, the test compound(s) formulated in an emulsifiable concentrate or wettable powder and diluted with water were sprayed at a rate of 10 ml per pot. Then, the seedlings were inoculated with a mixed spore suspension of the drug-resistant and drug-sensitive strain of Botrytis cinerea by spraying and placed at 20° C. in a room of high humidity for 5 days. The degree of damage was determined in the same manner as in Experiment 1, and the results are shown in Table 12.
