Abstract

Tetrachlorophthalamic acids of the formula ##STR1## in which R.sup.1 represents a trihalogenomethyl, trihalogenomethoxy or trihalogenomethylmercapto group, PA1 R.sup.2 represents hydrogen, halogen or a lower alkyl or lower alkoxy group, or PA1 R.sup.1 together with R.sup.2, in the o-position relative to each other, denote --O--CF.sub.2 --O--CF.sub.2 --,--O--CF.sub.2 --O--or --O--CF.sub.2 --CFX--O--, wherein PA1 X represents hydrogen, chlorine or fluorine, and PA1 R.sup.3 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.
