Abstract
Abstract The invention is directed to a herbicidal composition which is a concentrated, oil/water emulsion formulation (CE). The concentrated emulsion formulations of the invention are particularly useful for formulating herbicidal agents which have a solution point in solvent at around 25 DEG C. or less, particularly 2-chloro-2',6'-diethyl-N-(methoxymethyl)acetanilide, N-(ethoxymethyl)-2'-trifluoromethyl-6'-methyl-2-chloroacetanilide and S-2,3,3-trichloroallyl diisopropyl thiocarbamate. The concentrated oil/water emulsion formulations of the present invention are comprised of the following components: -Component % By Weight -Active Herbicidal Agent 40-65 -Hydrocarbon solvent 15-30 -Emulsifier 2.5-10 -Co-Emulsifier 0.5-5 -Water (4-20% Agriculturally Balance -Acceptable Salt) -+TR Total 100.00

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
136 words
A herbicidal concentrated emulsion composition consisting essentially of the following components: A. from about 40.0 to about 65.0 percent by weight of a 2-haloacetanilide or thiocarbamate herbicide which is a solid at room temperature and which has a solution point in water of about 25° C. or less; B. from about 15.0 to about 30.0 percent by weight of a hydrocarbon solvent; C. from about 2.5 to about 10.0 percent by weight of an emulsifier which is a nonionic emulsifying agent having an HLB of 18.0 or greater; D. from about 0.5 to about 5.0 percent by weight of a C 14-20 straight chain alcohol; and E. balance being made up of water containing an agriculturally acceptable salt or urea at a concentration of from about 4.0 to about 20.0 percent by weight of the water.
Claim 2
Dependent Claim
136 words
A herbicidal concentrated emulsion composition consisting essentially of the following components: A. from about 40.0 to about 65.0 percent by weight of a 2-haloacetanilide or thiocarbamate herbicide which is a solid at room temperature and which has a solution point in water of about 25° C. or less; B. from about 15.0 to about 30.0 percent by weight of a hydrocarbon solvent; C. from about 2.5 to about 10.0 percent by weight of an emulsifier which is a nonionic emulsifying agent having an HLB of 18.0 or greater; D. from about 0.5 to about 5.0 percent by weight of a C 14-20 straight chain alcohol; and E. balance being made up of water containing an agriculturally acceptable salt or urea at a concentration of from about 4.0 to about 20.0 percent by weight of the water.
Claim 3
Dependent Claim
24 words
An emulsion composition according to claim 1 wherein said herbicide is selected from the group consisting of 2-chloro-2',6'-diethyl-N-(methoxymethyl)-acetanilide, N-(ethoxymethyl)-2'-trifluoromethyl-6'-methyl-2-chloroacetanilide, S-2,3,3-trichloroallyl diisopropylthiocarbamate and S-2,3-dichloroallyl diisopropylthiocarbamate.
