Brassinosteroid biosynthesis inhibitors

Abstract

Compound represented by the following formula (I): wherein R1 represents a lower alkyl group, R2 represents a phenyl group which may be substituted or a lower alkyl group and R3 represents a phenyl group which may be substituted (e.g., 4-(4-chlorophenyl)-2-phenyl-3-(1,2,4-triazoyl)-butan-2-ol) or salts thereof. The compounds have a specific inhibitory action against the brassinosteroid biosynthesis, and are useful as plant growth regulators.
