Herbicidal compositions comprising phenyl carbamates and other herbicides
First Claim
1. A stabilized liquid herbicidal composition comprising as an active ingredient a herbicidally effective amount of phenmedipham and/or desmedipham in which the active ingredient in a finely ground state is dispersed in an acidic liquid phase which comprises at least one oily component in an amount of 5-75% by weight, and at least one surfactant in an amount of 5-60% by weight, said oily component and surfactant may be able to form a stable solution which is capable of effectively suspending the active ingredient and said oily component being a mixture comprising a mineral oil, a chlorinated mineral oil or a vegetable oil in combination with at least one lower carboxylic acid ester of a monoalcohol or polyalcohol.

Abstract
Stabilized liquid herbicidal compositions containing at least one substituted phenyl carbamate of the general formula I ##STR1## in which R1 represents a C1 -C6 alkyl group, a C3 -C6 cycloalkyl group or an aryl group, which aryl group may be substituted by a halogen atom and/or a C1 -C6 alkyl group and/or a trifluoromethyl group, and R2 represents a C1 -C6 alkyl, C2 -C6 alkenyl or C2 -C6 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.
