The invention provides a compound of the general formula
wherein X is an oxygen or sulfur atom or a vinylene group, each of ℓ and m is an integer of 1 to 4, n is 0 or 1, the heterocycle comprising the nitrogen atom, the two alkylene chains and X is 5- or 7-membered, the two alkylene chains each may be branched, Y1 is a halogen atom, Y2 is a hydrogen or halogen atom, R is an alkyl group, which may be interrupted by one or more oxygen atoms, or an optionally halo-substituted alkenyl or alkynyl group and Z is an oxygen or sulfur atom. The invention also provides herbicidal compositions containing (thiono)carbamates of the above formula as active ingredient and a method of controlling weeds using these (thiono)carbamates. The phenyl (thiono) carbamates are capable of effectively controlling broad-leaved annual weeds and annual weeds belonging to the families Gramineae and Cyperaceae such as wild Echinochloa species, monochoria, toothcup and umbrella plant. The (thiono)carbamates are substantially nonphytotoxic to useful crop plants such as the paddy rice plant.
