摘要

NEW MATERIAL:The compound of formula I [X is nitro, amino, thioisocyanato, group of formula II (A' is O or S; R<2> is lower alkyl, lower alkenyl, etc.), etc.; Y is lower alkyl, lower alkoxy, H, etc.; A is O or S; B is lower alkyl, lower alkenyl, lower cycloalkyl, etc.]. EXAMPLE:Isopropyl N-(3-chloro-4-ethoxy-5-methoxycarbonylaminophenyl)-carbamate. USE:An agricultural and horticultural fungicide effective to powdery mildew, scab, etc. of apple. It exhibits strong fungicidal effect against fungi resistant to benzimidazole thiophanate fungicides.
