Herbicidal mixtures

Abstract

This invention relates to herbicidal mixtures of chlorimuron ethyl and sulfentrazone, herbicidal compositions of said mixtures, and a method for the use of said mixtures to control undesired vegetation.

What is claimed is: 
     
       1. A herbicidal mixture comprising the compound of Formula I ##STR6## which is ethyl 2-    (4-chloro-6-methoxy-2-pyrimidinyl)amino!carbonyl!amino!sulfonyl!benzoate (chlorimuron ethyl) and agriculturally suitable salts thereof and the compound of Formula II ##STR7## which is N- 2,4-dichloro-5- 4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl!phenyl!methanesulfonamide (sulfentrazone), wherein the ratio of the compound of Formula I to the compound of Formula II is in the range of 1:20 to 1:75. 
     
     
       2. An agriculturally suitable composition for controlling the growth of undesired vegetation comprising an effective amount of the herbicidal mixtures of claim 1 and at least one of the following: surfactant, solid or liquid diluent. 
     
     
       3. The composition of claim 2 wherein the undesired vegetation is the vegetation in a soybean crop. 
     
     
       4. A method for controlling the growth of undesired vegetation comprising contacting the locus to be protected with a herbicidally effective amount of the composition of claim 2. 
     
     
       5. The method of claim 4 wherein the locus to be protected is a soybean crop.
