Abstract: 1342141 Fungicidal application of 2-hydroxyimino-acetamide 2-sulphoxides and sulphones E I DU PONT DE NEMOURS & CO 23 April 1971 [23 April 1970 5 March 1971] 11061/71 Heading A5E [Also in Division C2] The invention comprises fungicidal compositions containing an inert diluent and a compound as defined below; and a method of inhibiting the growth of fungus at a locus, e.g. a plant or part thereof, by applying to the locus a compound as defined below or a composition containing it. The active compounds are of formula:- wherein: R<SP>1</SP> is alkyl of 1 to 12 carbon atoms; alkyl of 3 to 12 carbon atoms substituted with 1 chlorine atom; alkenyl of 3 or 4 carbon atoms; cycloalkyl of 3 to 8 carbon atoms; cyclo-alkenyl of 5 to 8 carbon atoms; cycloalkylalkyl of 6 or 7 carbon atoms; phenyl; wherein R<SP>2</SP>, R<SP>3</SP> and R<SP>4</SP> are as defined below, p is 0, 1, or 2, and R<SP>8</SP> is phenylene, xylylene, or alkylene of 2 to 18 carbon atoms; each of R<SP>2</SP> and R<SP>3</SP>, which may be the same or different, is hydrogen; alkyl of 1 to 12 carbon atoms; alkenyl of 3 or 4 carbon atoms; cycloalkyl of 3 to 10 carbon atoms; cycloalkyenyl of 5 to 8 carbon atoms; cycloalkylalkyl of 6 or 7 carbon atoms; phenyl; or benzyl; with the provisos that (1) only one of R<SP>2</SP> and R<SP>3</SP> attached to the same nitrogen atom can be hydrogen, phenyl, or benzyl, and (2) the sum of carbon atoms in R<SP>2</SP> and R<SP>3</SP> attached to the same nitrogen atom can total no more than 12, except where both R<SP>2</SP> and R<SP>3</SP> are alkyl; or R<SP>2</SP> and R<SP>3</SP> taken together, along with the nitrogen atom to which they are attached, are a ring containing one nitrogen atom and 2 to 6 carbon atoms; or are a morpholino ring; R<SP>5</SP> is alkyl of 1 to 8 carbon atoms; propargyl, alkneyl of 3 to 4 carbon atoms; cycloalkyl of 3 to 8 carbon atoms; benzyl, phenyl; or phenyl substituted with 1 or 2 substituents selected from halogen, nitro, methoxy, and methyl; R<SP>6</SP> is alkyl of 1 to 11 carbon atoms; alkyl of 1 to 11 carbon atoms substituted with up to three substituents selected from chlorine, bromine, fluorine, or with up to 2 substituents selected from alkoxy of 1 or 2 carbon atoms, or with one alkoxy carbonyl of 2 or 3 carbon atoms; cycloalkyl of 3 to 8 carbon atoms; alkenyl of 2 to 6 carbon atoms; cycloalkenyl of 4 to 8 carbon atoms; bicycloalkenyl of 7 to 10 carbon atoms; cycloalkenylalkyl of 5 to 11 carbon atoms; cycloalkylalkyl of 4 to 11 carbon atoms; bicycloalkyl of 7 to 9 carbon atoms; adamantyl; benzyl; alkoxy of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms substituted with one bromine or chlorine, or with one alkoxy of 1 or 2 carbon atoms, or with one alkoxycarbonyl of 2 or 3 carbon atoms; and n is 1 or 2. The compositions may be in the form of wettable powders, suspensions, emulsifiable concentrates, dusts, solutions, granules or pellets, and can contain surface-active agents, other fungicides, bactericides, insecticides, iaicaricides or nematocides, as well as other additives. Lists of diluents and other ingredients are given.
