AMINE AND AMINE OXIDE SURFACTANTS FOR CONTROLLING HERBICIDE SPRAY DRIFT

摘要

Spray drift during the application of an aqueous mixture of glyphosate and an auxinic herbicide is reduced by incorporating certain tertiary amine or tertiary amine oxide surfactants into the aqueous solution or mixture to be sprayed.

主权项

1. A method to reduce spray drift during the application of an aqueous herbicidal spray mixture containing glyphosate and an auxinic herbicide comprising incorporating into the aqueous herbicidal spray mixture from about 0.02 to about 2 weight percent of a tertiary amine oxide surfactant of the formula: wherein R4 is a straight or branched chain (C10-C18) alkyl or an alkyletherpropyl or alkylamidopropyl of the formula: wherein R7 is a straight or branched chain (C10-C18) alkyl, and R5 and R6 independently are straight or branched chain (C1-C18) alkyl or ethoxylates or propoxylates of the formula: wherein n is an integer from 1 to 20,or mixtures thereof, wherein the auxinic herbicide is a water soluble salt of dicamba.
