The antifungal activity of 37 N-(methoxy-substituted benzoyl)anthranilic esters was tested on the powdery mildew of barley caused by Erysiphe graminis by the pot test. Among the methyl N-(methoxy-substituted benzoyl)anthranilates tested, 3, 4-dimethoxybenzoyl derivative exhibited the highest activity. The variation in fungicidal activity of N-(3, 4-dimethoxy-benzoyl)anthranilic esters was shown to be related with variation in hydrophobicity and the electronic property of the alcohol moiety of the ester. The branching at the α-position of the alcohol moiety of the ester was detrimental to the activity.
