Sulfonamide derivatives of the formula
wherein
W is 0 or S;
R is H or CH3;
J is a phenyl, thienyl, pyrazolyl or pyridyl group, each substituted by a tetrazolyl moiety;
A is mono- or bicyclic heterocyclic group, e.g. pyrimidinyl or triazinyl;
and their agriculturally suitable salts, exhibit potent therbicidal activity. Some also show a plant growth regulant effect.
The novel compounds may be made e.g. by reacting a sulfonyl isocyanate or sulfonyl isothiocyanate JNCW with an appropriate heterocyclic amine HNR.A.
