Abstract: A method of inducing male sterility in a dicotyledonous plant which comprises treating the plant prior to, during or post meiosis with an amount of a substituted 4-oxo-1-phenyl-1,4-dihydropyridazine, which is effective to produce male sterility in the plant.

Abstract: A composition and method for thinning Perlette Seedless grape clusters is disclosed. The composition contains a surfactant and a gibberellin. In a method for thinning Perlette Seedless grape clusters, the composition is applied to Perlette Seedless grape clusters during bloom, with the result that clusters are produced that have fewer grapes and in which the grapes are increased in size and weight.
