Spray drift reduction agents comprising low hydrophilic-lipophilic balance surfactants

Abstract

Embodiments of the present invention disclose using low hydrophilic-lipophilic balance surfactants as spray drift reduction agents and methods of using such agents.

1 ) A spray drift reduction agent comprising a low hydrophilic-lipophilic balance surfactant. 
     
     
         2 ) A pesticidal composition to reduce spray drift that comprises one or more active ingredients and one or more low hydrophilic-lipophilic balance surfactants. 
     
     
         3 ) A composition of  claim 2  wherein the one or more active ingredients comprise a herbicide. 
     
     
         4 ) A composition of  claim 2  wherein the one or more active ingredients comprise an insecticide. 
     
     
         5 ) A composition of  claim 2  wherein the one or more active ingredients comprise a fungicide. 
     
     
         6 ) A method of reducing spray drift comprising providing a composition for spraying that comprises a pesticide and a low hydrophilic-lipophilic balance surfactant and spraying the composition. 
     
     
         7 ) A method of reducing spray drift comprising:
 adding a surfactant to a spray mixture; and,   spraying the spray mixture at a temperature above the surfactant's cloud point as measured in the spray mixture.   
     
     
         8 ) A spray composition comprising a blend of two or more surfactants wherein the blend has a low hydrophilic-lipophilic balance. 
     
     
         9 ) A method of producing a spray drift reduction composition comprising blending a low hydrophilic-lipophilic balance surfactant with a second surfactant to produce a blend with a low hydrophilic-lipophilic balance.
