Activity of Bicyclic Benzanilides against Rice Sheath Blight

Abstract

A variety of benzanilides with a dihydrofuran, tetrahydronaphthalene or indane ring were synthesized, and their fungicidal activities against rice sheath blight were studied. Of the compounds tested, N-(1, l-dimethyl-4-indanyl)-2-(trifluoromethyl)benzamide was the most effective, showing the importance of substituents at the 1-position of the indanyl systems. The examination on its preventive and curative effects revealed that N-(l, 1-dimethyl-4-indanyl)-2-(trifluoromethyl)benzamide was a promising fungicide whose activity was higher than mepronil and flutolanil. © 1989, Pesticide Science Society of Japan.
