Antifungal Activities of α-Isocyanoacetanilides

Abstract

A series of α-isocyanoacetic acid compounds was examined for their inhibitory activities against several plant-fungi. Among them, various α-isocyanoacetamides showed protective effects against Sphaerotheca fuliginea, Cladosporium fulvum and Phytophthora infestans at the concentration of 1000 ppm. Particularly, α-isocyanoacetanilides (9 g and 9 h) exhibited more potent activity than maneb against Cladosporium fulvum in tomato seedlings.
