ABSTRACT:
Stabilized liquid herbicidal compositions containing at least one substituted phenyl carbamate of the general formula I ##STR1## in which R.sup.1 represents a C.sub.1 -C.sub.6 alkyl group, a C.sub.3 -C.sub.6 cycloalkyl group or an aryl group, which aryl group may be substituted by a halogen atom and/or a C.sub.1 -C.sub.6 alkyl group and/or a trifluoromethyl group, and R.sup.2 represents a C.sub.1 -C.sub.6 alkyl, C.sub.2 -C.sub.6 alkenyl or C.sub.2 -C.sub.6 alkynyl group that may be substituted by a terminal halogen atom, and optionally at least one herbicidally active compound selected from the group consisting of 5-amino-4-chloro-2-phenyl-3(2H)pyridazinone, 2-ethoxy-2,3-dihydro-3,3-dimethylbenzofuran-5-yl methanesulphonate, and 4-amino-4,5-dihydro-3-methyl-6-phenyl-1,2,4-triazin-5-one are prepared by dispersing the compound(s) in finely ground state in a liquid phase which comprises one or more oily components and one or more surfactants and which is able to form an oil-in-water emulsion or a microemulsion when mixed with water.
