Pesticidal compositions and methods of use thereof

Abstract

The present invention is directed to pesticidal compositions comprising a pesticide, one or more acidifiers and one or more antagonists of the pesticide. The present invention is further directed to methods of controlling weeds by mixing pesticidal compositions comprising a pesticide and one or more acidifiers with one or more antagonists of the pesticide to create a tank mix and applying the tank mix to the weeds or an area in need of weed control.

         12 . A method of controlling weeds comprising:
 a. mixing a composition comprising a pesticide and one or more acidifiers with one or more antagonists to the pesticide to create a tank mix; and   b. applying the tank mix to the weeds or an area in need of weed control.   
     
     
         13 . The method of  claim 12 , wherein the composition has a pH of 5.3 or less. 
     
     
         14 . The method of  claim 12 , wherein the composition has a pH of 4.75 or less. 
     
     
         15 . The method of  claim 12 , wherein the one or more acidifiers is selected from the group consisting of: sulfuric acid; a mixture of alkyl polyoxyethylene ether, methylacetic acid and phosphatidylcholine; a mixture of carboxylic acids, phosphoric acids and ammoniated ions; and a mixture of trisodium citrate dihydrate, alkyl polyglucoside, monocarbamide, dihydrogen sulfate and tallow amine ethoxylate. 
     
     
         16 . The method of  claim 12 , wherein the pesticide is a graminicide. 
     
     
         17 . The method of  claim 12 , wherein the pesticide is selected from the group consisting of a dim herbicide, a fop herbicide and a den herbicide. 
     
     
         18 . The method of  claim 12 , wherein the pesticide is selected from the group consisting of an imidazoline, a sulfonylaminocarbonyltriazolinone, a sulfonylurea, a pyrimidinyl(thio)benzoate, a triazolpyramidine and a triazolone.
