Synthesis and plant disease controlling activities of N-substituted 2-hydroxymethyl-3,4,5,6-tetrachlorobenzamide derivatives

Five N-substituted 2-hydroxymethyl-3, 4, 5, 6-tetrachlorobenzamide derivatives were prepared by reduction of corresponding phthalimide derivatives with sodium borohydride. They were tested for their potential activity to control several plant diseases. No control activity was manifested on bacterial leaf blight of rice, but some showed high activity against rice blast and cucumber anthracnose.
