ABSTRACT:
The present invention relates to N-alkyl-2-aryl-4-oxonicotinates, N-alkyl-5-aryl-4-oxonicotinates, N-alkyl-6-aryl-4-oxonicotinates and N-alkyl-2,6-diaryl-4-oxonicotinates and their use as plant hybridization agents especially useful in wheat, barley and corn. These compounds are particularly active as chemical gametocides and possess a high degree of male/female selectivity. Moreover, these compounds are relatively noninjurious to both corn and wheat crops. The fact that these chemicals possess a high degree of male sterility without affecting female fertility makes them very useful as chemical gametocides.
