FUNGICIDES COMPRISING 3-HYDRAZINO-BENZISOTHIAZOLE-1,1-DIOXIDE DERIVATIVES AS ACTIVE SUBSTANCE AND PROCESS FOR PREPARING 3-/ALKYL-CARBAMOYL-HYDRAZINO-BENZISOTHIAZOLE-1,1-DIOXIDE DERIVATIVES

摘要

Compounds of the formula IMAGE in which R1 is alkyl, cycloalkyl, aryl or hydrogen, R2 is -CO-R3, R3 is alkyl, alkenyl or cycloalkyl, or is phenyl which is optionally substituted, or is alkoxy or benzyl, or is phenoxy which is optionally substituted, or is phenoxymethyl, alkylamino, cycloalkylamino or phenylamino, or R1 and R2 together are a IMAGE group, R4 and R5 each independently is hydrogen, alkyl, cycloalkenyl or phenylalkenyl, or is phenyl which is optionally substituted by alkyl, halogen and/or alkoxy, or is furyl, or R4 and R5 together are alkylene having 4 to 6 carbon atoms, are fungicidally active. Those compounds wherein R3 is alkylamino, cycloalkylamino or phenylamino, with the exception of the compound in which R1 is hydrogen and R6 is phenylamino, are new.
