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 at least one compound of the formula:
wherein R¹ is a carboxy group (-COOH), or an agronomically acceptable salt thereof, or alkoxycarbonyl having up to 12 carbon atoms in the alkoxy moiety; R² is phenyl or substituted phenyl having up to three substituents collectively having a total of 0 to 6 carbon atoms, the substituents being selected from alkyl, C₄H₄=forming a naphthyl group, alkoxy, phenoxy, halogen, nitro, perhaloalkyl, alkyoxyalkyl, alkoxyalkoxy, amino, alkyl- or dialkylamino, cyano, alkoxycarbonyl, sulpho, sulphonamide, alkylcarbonyl, carbamoyl, alkyl- or dialkyl carbamoyl, carboxyalkyl, alkanoyloxy, haloalkyl, alkanoylamino, alkylthio, alkylsulphinyl and alkylsulphonyl, R³ is alkyl preferably having from 1 to 4 carbon atoms and R⁴ is hydrogen, alkyl, preferably having from 1 to 4 carbon atoms, or halogen.
