Tetrachlorophthalamic acids of the formula in which R1 represents a trihalogenomethyl, trihalogenomethoxy or trihalogenomethylmercapto group, R2 represents hydrogen, halogen or a lower alkyl or lower alkoxy group, or R1 together with R2, in the o-position relative to each other, denote -O-CF2-O-CF2-,-O-CF2-O-or -O-CF2-CFX-O-, wherein X represents hydrogen, chlorine or fluorine, and R3 represents hydrogen, halogen or a lower alkyl, lower alkoxy, lower alkylmercapto or aryloxy group, the aryloxy being optionally substituted which possess activity against bacteria, particularly those which attack plants.
