A class of 2-arylpyrimidines which is useful in the control of weeds of the general formula: ##STR1## wherein R.sup.2 is an optionally substituted aromatic ring; R.sup.3 is a saturated or unsaturated alkyl group; R.sup.5 is selected from acyl, alkoxyalkyl, alkoxyimino, dialkoxyalkyl, formyl, hydroxyalkyl, alkoxyalkoxy, cyanoalkyl and hydroxyimino; R.sup.6 is selected from hydrogen, halo, alkyl, haloalkyl, aryl, and alkoxy; and X is oxygen or sulfur.

2-arylpyrimidines and herbicidal use thereof

A class of 2-arylpyrimidines which is useful in the control of weeds of the general formula: ##STR1## wherein R.sup.2 is an optionally substituted aromatic ring; R.sup.3 is a saturated or unsaturated alkyl group; R.sup.5 is selected from acyl, alkoxyalkyl, alkoxyimino, dialkoxyalkyl, formyl, hydroxyalkyl, and hydroxyimino; R.sup.6 is selected from hydrogen, halo, alkyl, haloalkyl, aryl, and alkoxy; and X is oxygen or sulfur.

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.

Hybridization of sunflowers and safflowers

Compounds of the formula ##STR1## wherein R.sup.1 is hydrogen, alkyl, aryl, or aralkyl,

6-Oxopyrimidine plant growth regulators

This disclosure teaches that certain halo aniline derivatives, when applied post-emergence to plants, effect a modification of the growth pattern of said plant.

Haloaniline derivatives as plant growth modifiers

Novel compounds belonging to the class of 3-carboxy (or the physiologically acceptable salts thereof), 3-carbalkoxy, and 3-carbamoyl-1-alkyl-4,6-disubstituted pyrid-2-ones. These compounds possess biological activity and in particular are gametocides and plant growth regulators. Novel 3-cyano-1-alkyl-4,6-disubstituted pyrid-2-ones are also disclosed as intermediates.

1-Alkylpyrid-2-ones

Novel compounds belonging to the class of 1-substituted benzylpyrid-2-one-4,6-dialkyl and 4,5,6-trisubstituted-3-carboxylic acids, amides, esters and physiologically acceptable salts. These compounds possess biological activity and in particular are gametocides and plant growth regulators. Novel 1-substituted benzyl-3-cyano-4,5,6-trisubstituted pyrid-2-ones are also disclosed as intermediates.
