Abstract
Novel herbicidal thiadiazoles of the formula: ##STR1## (wherein: R.sup.1 represents a group R.sup.a, --S(O)nR.sup.a or --SO.sub.2 NR.sup.a R.sup.b, where R.sup.a and R.sup.b, which may be the same or different, each represent hydrogen, cycloalkyl of 3 to 7 carbon atoms, alkenyl or alkynyl of 2 to 6 carbon atoms, phenyl, phenylalkyl of 7 to 10 carbon atoms, or alkyl of 1 to 10 carbon atoms, any phenyl or alkyl group present being optionally substituted by one or more halogen atoms, cyano groups, alkoxy or alkylthio groups of 1 to 4 carbon atoms, or phenoxy groups, or R.sup.a and R.sup.b together form an alkylene chain of 2 to 6 carbon atoms, and n represents 0, 1 or 2; PA0 X represents oxygen or sulphur; PA0 Z represents a group --NR.sup.c R.sup.d ; and PA0 Y represents a group --NR.sup.e R.sup.f or a group --N.dbd.CR.sup.e R.sup.f ; where R.sup.c, R.sup.d, R.sup.e and R.sup.f, which may be the same or different, each represent a group as defined for R.sup.a, or a carboxy, alkoxy, alkoxycarbonyl, acyl, acyloxy, alkylsulphonyl, cyano, formyl, amido or heterocyclyl group, any alkyl moiety of which is of 1 to 4 carbon atoms); and the acid addition salts thereof, compositions containing…
