Embodiments of the present invention disclose using low hydrophilic-lipophilic balance surfactants as spray drift reduction agents and methods of using such agents. Such surf act ants generally reduce the amount of fines generated during spraying. Rather, other surfactants usually increase the amount of fines when added to the spray tank since the reduced tension makes it easier for the spray drops to break up. A pesticidal composition to reduce spray drift that comprises one or more active ingredients and one or more low hydrophilic-lipophilic balance (HLB) surfactants. In embodiments, the one or more active ingredients may be herbicides, insecticides, fungicides or combinations thereof. Such herbicides may be water soluble herbicides or other herbicides such as 2,4-D esters. The one or more active ingredients may be glyphosate or one or more salts or esters thereof. |
