USE OF CERTAIN N-ACETONYLBENZAMIDES AS FUNGICIDES ABSTRACT Certain N-acetonylbenzamides exhibit low toxicity to plants are particularly useful for control of fungi, especially Phytomycetes. The aforesaid N- acetonylbenzamides are compounds of the general formula Image wherein A is a chloro, bromo, fluoro, iodo, trifluoromethyl, trifluoromethoxy, fluorosulfonyl, methyl, ethyl, phenyl, methoxy, chloromethyl, (C1- C2)alkoxycarbonyl, cyano or hydroxy group; A1 and B are each independently selected from the group consisting of hydrogen, chloro, bromo, fluoro and methyl; X is a bromo, iodo, fluoro, cyano, thiocyano, isothiocyano, methylsulfonyloxy, thio(C1-C2)alkyl, (C1- C2)alkoxy, carbamoyloxy (-OC(O)NR3), thiocarbamoylthio (- SC(S)NR3), hydroxy, azide, (C1-C4)alkylcarbonyloxy, phenylcarbonyloxy, phenoxy, phenylthio, trifluoromethyl- carboxy (C1-C3)alkylthioacetyl, imidazolyl or triazolyl group; and when X is a phenylcarbonyloxy, a phenoxy or phenylthio substituent, the phenyl moiety may be substituted with one substituent selected from the group consisting of chloro, fluoro, bromo, iodo or methyl; Y and Z are each independently a hydrogen, bromo, chloro, iodo, fluoro, cyano, thiocyano, isothiocyano, methylsulfonyloxy, thio(C1-C2)alkyl, (C1-C2alkoxy, carbamoyloxy (-OC(O)NR3), hydroxy, azide or (C1- C4)alkylcarbonyloxy group and either Y or Z may be a (C1- C3)alkylsulfonyl imidazolyl or triazolyl group, provided that when X and Y are halogens and Z is hydrogen or when X, Y and Z are all halogens, then the halogens are all the same halogen; R1 and R2 are each independently a hydrogen atom or a (C1-C6)alkyl group; and each R3 is independently a hydrogen or a (C1- C4)alkyl group.
