Abstract

Abstract Compounds of the formula wherein R is H or CH 3 ; Q is an optionally substituted imidazole, pyrazole, thiazole or isothiazole moiety; A is a heterocyclic group, e.g. pyrimidin-2-yl; and their agriculturally suitable salts, exhibit herbicidal and plant growth regulant effects. The compounds may be formulated for use in conventional manner. They may be made by various methods, e.g. by the reaction of a sulfonyl isocyanate QS0 2 NCO with an aminoheterocycle HN(R)A.
