FIELD: agriculture.
SUBSTANCE: invention relates to agriculture. To reduce the drift of an aerosol by applying an aqueous herbicidal spray mixture containing glyphosate and auxin herbicide, aqueous herbicidal mixture is added for spraying from about 0.02 to about 2 weight percent of a tertiary amine surfactant of the formula: 
, where R1 is straight or branched chain (C12-C18)alkyl; and R2 and R3 are independently straight or branched chain (C1-C18)alkyl, and a tertiary amine oxide surfactant of the formula: 
, where R4 is straight or branched chain (C10-C18)alkyl, or alkyl ether propyl, or alkylamidopropyl of the formula: 
or 
, where R7 is straight or branched chain (C10-C18)alkyl; and R5 and R6 are independently straight or branched chain (C1-C18)alkyl, or ethoxylates, or propoxylates of the formula: 
or 
, where n is an integer from 1 to 20 or their mixtures.
EFFECT: invention enables to achieve the specified purpose.
