Pollen formation in cereal grain plants is inhibited by application of a 4-carboxy(or derivative)-1-aryl-5-pyrazolecarboxamide. Production of hybrid seed is facilitated by use of the compounds.
Use of a 4,5-dicarboxy or 5-carboxamido-4-carboxy (or derivatized carboxy)-1-(3,5-disubstituted-phenyl)pyrazole in the production of hybrid seed, and a method for producing 5-carboxamido-4-carboxy-1-(3,5-dimethylphenyl)pyrazole.
