Abstract
Novel crystalline adducts of a carbamoyl sulphoxide and urea have the formula ##EQU1## wherein R is substituted or unsubstituted aryl, alkyl or alkenyl; R.sub.1 and R.sub.2, which may be the same or different, are H, substituted or unsubstituted alkyls, alkenyls or aryls, or aliphatic groups that, bound to one another in the form of a chain --(CH.sub.2).sub.p --(X).sub.n --(CH.sub.2).sub.q -- (in which p = 1,2,3; q = 1,2,3; X, =O, =S, =SO, =SO.sub.2 ; n = 0 or 1), form with N a ring when n = 1 and (p+q) .ltoreq. 4. The adducts have herbicidal properties and herbicide compositions containing the adducts as well as process for inhibiting the growth of plants or for destroying them are contemplated.
