  • Certain-2,6-diphenyl-1,4-dihydro-4-oxo-nicotinates which are useful for inducing male sterility in cereal grain plants
    Patent number: 4964896
    Abstract: This invention relates to compounds of the formula: ##STR1## wherein R.sub.1 is an optionally substituted alkyl or alkenyl group; at least one of R.sub.2, R.sub.5 and R.sub.6 is ##STR2## wherein (1) when R.sub.2 is ##STR3## R.sub.5 is a hydrogen atom, an alkyl group or a halogen atom and R.sub.6 is a hydrogen atom or an alkyl group,(2) when R.sub.5 is ##STR4## R.sub.2 is an alkyl group and R.sub.6 is a hydrogen atom or an alkyl group,(3) when R.sub.6 is ##STR5## R.sub.2 is an optionally substituted (C.sub.1 -C.sub.6) alkyl or a (C.sub.3 -C.sub.6) alkenyl group and R.sub.5 is a hydrogen atom, a (C.sub.1 -C.sub.6) alkyl group or a halogen atom, and(4) when R.sub.2 and R.sub.6 are both independently ##STR6## R.sub.5 is hydrogen atom or an alkyl group; Y is a hydrogen atom or an alkyl group; X is a hydrogen atom, a halogen atom, a trihalomethyl group and the like; and n is an integer from 1 to 3; or the agronomically acceptable alkali metal or acid addition salts thereof.

  • Aryl-4-oxonicotinates useful for inducing male sterility in cereal grain plants
    Patent number: 4936904
    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.
