摘要

A method of inducing male sterility in an agricultural or horticultural dicotyledonous plant which comprises treating the plant prior to, during, or post meiosis with an amount, which is effective to produce male sterility in the plant, of at least one compound of the formula:- CHEM wherein R1 is (C1-C6) alkyl or (C2-C6) alkenyl, each optionally substituted with a group selected from hydroxy, carboxy, carboxy salt, phenyl and phenyl substituted with up to two of the same or different substitutents selected from halogen, methyl, ethyl, methoxy, ethoxy, trifluoromethyl, nitro, and cyano; R5 is hydrogen, (C1-C6) alkyl or halogen; R6 is hydrogen, or (C1-C6) alkyl; X is halogen, trihalomethyl, (C1-C6) alkyl, nitro, cyano or (C1-C6) alkoxy; n is 0 or an integer of 1-3; and Y is hydrogen or (C1-C6) alkyl; and agronomically acceptable acid addition salts; and carboxy salts of compounds of formula (I) where Y is hydrogen, having an agronomically acceptable cation.
