Abstract: The present invention discloses a complex suspended herbicide formulation including: a herbicidally active ingredient of thiolcarbamate type which is liquid at common temperature; a solid herbicidally active ingredient which is slightly soluble in the herbicidally active ingredient of thiolcarbamate type at common temperature; a surfactant; and a dry process white carbon; wherein the solid herbicidally active ingredient is dispersed and suspended in the herbicidally active ingredient of thiolcarbamate type in the presence of the surfactant and the dry process white carbon; and wherein the herbicidally active ingredient of thiolcarbamate type is represented by the formula: ##STR1## wherein R.sup.1 is an alkyl group having from 1 to 3 carbon atoms, a phenyl group, or a halogen-substituted phenyl group; R.sup.2 and R.sup.3 are alkyl groups having from 1 to 5 carbon atoms, with the proviso that R.sup.2 and R.sup.3 may form a ring.

Abstract: A substituted aryloxyurea of the formula: ##STR1## wherein Ar represents ##STR2## in which X.sup.7 represents a hydrogen atom, a halogen atom, a cyano group, a lower alkoxy group or a trifluoromethyl group, andR.sup.1 and R.sup.2 together form together with carbon and the nitrogen atom to which they are bonded a 4-8 membered heterocyclic ring.The substituted aryloxyureas exhibit an excellent herbicidal efficacy against weeds when applied, for example, to the weeds in a wide range of period from a preemergence stage to a growth stage.The substituted aryloxyureas of the invention have the excellent advantage of maintaining high safety on crops or crop plants in spite of their herbicidal efficacy.
