Pesticide formulation with streaming birefringence

Abstract

A pesticide composition exhibiting streaming birefringence and methods for making the pesticide composition are disclosed. In one embodiment, the pesticide composition comprises an active ingredient and a surfactant adjuvant.

1 . A pesticide composition comprising: an active ingredient; and a surfactant adjuvant, wherein the pesticide composition exhibits streaming birefringence. 
   
   
       2 . The pesticide composition of  claim 1 , wherein the active ingredient comprises a glyphosate or glyphosate salt. 
   
   
       3 . The pesticide composition of  claim 2 , wherein the surfactant adjuvant comprises a lard dimethylaminopropylamine amidoamine oxide surfactant. 
   
   
       4 . The pesticide composition of  claim 1 , wherein the surfactant adjuvant comprises a phosphate ester of a tallow amine ethoxylate. 
   
   
       5 . The pesticide composition of  claim 4 , wherein the surfactant adjuvant further comprises an allkylpolysaccharide. 
   
   
       6 . The pesticide composition of  claim 1 , wherein the pesticide composition comprises greater than about 50 wt. % glyphosate salt. 
   
   
       7 . The pesticide composition of  claim 6 , wherein the glyphosate salt comprises a mixture of potassium and IPA. 
   
   
       8 . A method of making a pesticide composition comprising:
 mixing a glyphosate salt and a surfactant adjuvant such that a thermodynamically stable phase results, said resultant thermodynamically stable phase to exhibit birefringence under flow only.   
   
   
       9 . The method of  claim 8  wherein mixing said glyphosate salt and said surfactant adjuvant includes adding one or more glyphosate salts to result in at least 600 grams acid equivalents per liter glyphosate. 
   
   
       10 . The method of  claim 8  wherein mixing said glyphosate salt and said surfactant adjuvant includes mixing a potassium glyphosate salt and a phosphate ester of a tallow amine surfactant or a lard dimethylaminopropylamine amidoamine oxide surfactant. 
   
   
       11 . A pesticide composition comprising:
 an active ingredient combined with one or more surfactants, said combination of said active ingredient and said one or more surfactants to exhibit birefringence under flow, but not at rest.   
   
   
       12 . The pesticide composition of  claim 11  wherein said active ingredient is one or more glyphosate salts. 
   
   
       13 . The pesticide composition of  claim 12  wherein the loading of said one or more glyphosate salts in said pesticide composition is at least 600 grams acid equivalents per liter glyphosate. 
   
   
       14 . The pesticide composition of  claim 13  wherein said active ingredient is a mixture of potassium glyphosate and an isopropylamine glyphosate. 
   
   
       15 . The pesticide composition of  claim 11  wherein said active ingredient is one of metolachlor or tebuconazole. 
   
   
       16 . The pesticide composition of  claim 11  wherein one of the one or more surfactants is an alkylamine alkoxylate phosphate ester. 
   
   
       17 . The pesticide composition of  claim 16  wherein another of the one or more surfactants is an alkylpolysaccharide. 
   
   
       18 . The pesticide composition of  claim 17  wherein said one of said one or more surfactants is a phosphate ester of a tallow amine ethoxylate. 
   
   
       19 . The pesticide composition of  claim 11  wherein one of said one or more surfactants is a lard dimethylaminopropylamine amidoamine oxide surfactant. 
   
   
       20 . The pesticide composition of  claim 19  wherein said active ingredient is a potassium glyphosate salt.
