N-2,6-DICHLORO-(4-TRIFLUOROMETHYL)PHENYLBENZENESULFONAMIDE DERIVATIVE COMPOUNDS HAVING ANTIFUNGAL ACTIVITIES AGAINST PHYTOPATHOGENS AND METHOD FOR CONTROLLING PHYTOPATHOGENS BY USING THE SAME

摘要

PURPOSE: Provided are N-2-dichloro-4-nitrophenyl benzenesulfonamide derivative compounds which have antifungal activities against phytopathogens including Rhizoctonia solani(Phytophthora sp. Pythium sp.), Botrytis cinerea and the like. Also, provided is a method for controlling phytopathogens by using the same. CONSTITUTION: The N-2-dichloro-4-nitrophenyl benzenesulfonamide derivative compounds are represented by the formula(1). In the formula(1), R is represented by the formula(wherein, R2 is hydrogen or trifluormethoxy group(-OCF3); R3 is bromine atom, trifluormethyl group(-CF3) or hydrogen atom; R4 is hydrogen atom or bromine atom; R5 is hydrogen atom or trifluormethyl group) or 2,5-dichlorothiopen.
