Herbicidal composition comprising a liquid thiocarbamate herbicide, a solid herbicide, surfactant, and dry process silicic acid

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.
