摘要:
Novel substituted thiophenesulfonamide compounds useful as herbicides which are represented by the following formula, and salts thereof: ##STR1## wherein either one of X and Y is an ethenyl or propenyl group having all hydrogen atoms replaced by chlorine atoms and/or fluorine atoms, and the other is the group ##STR2## (wherein R.sub.1 and R.sub.2 are each a methyl or methoxy group, and A is .dbd.N-- or .dbd.CH--).
摘要:
A sulfonamide compound and a salt thereof is represented by the following general formula: ##STR1## wherein each of X.sub.1, X.sub.2, and X.sub.3 independently represents a hydrogen atom or a halogen atom, each of Y.sub.1, Y.sub.2, and Y.sub.3 independently represents a halogen atom, and R represents a methyl group or a methoxy group, and is effective as an active ingredient of a herbicidal composition.

摘要:
A substituted pyridinesulfonamide compound or its salt represented by the following general formula (I): ##STR1## wherein A is CH or N; when A is CH, R.sub.1 and R.sub.2 may be either each independently a member selected from the group consisting of unsubstituted or substituted alkyl groups, unsubstituted or substituted alkenyl groups, unsubstituted or substituted cycloalkyl groups, and unsubstituted or substituted phenyl groups; when A is N, R.sub.1 is an unsubstituted or substituted alkyl group, R.sub.2 is an unsubstituted or substituted alkyl group, or an unsubstituted or substituted alkoxy group; and X and Y are each independently a member selected from the group consisting of alkyl groups and alkoxy groups, is disclosed. This compound is useful as the effective ingredient of a herbicide showing a wide weed-control spectrum even if used in a small amount.
