Abstract

Herbicidal compositions are provided comprising glyphosate or a salt thereof and an etheramine surfactant having the representative chemical structure (a) (see formula I) wherein R1 is a straight or branched chain C6 to about C22 alkyl, aryl or alkylaryl group, m is an average number from 1 to about 10, R2 in each of the m (O-R2) groups is independently C1-C4 alkylene, R3 groups are independently C1-C4 alkylene, and x and y are average numbers such that x+y is in the range tram 2 to about 60; or (b) (see formula II) wherein R1 is a straight or branched chain C6 to about C22 alkyl, aryl or alkylaryl group, m is an average number from 1 to about 10, R2 in each of the m (O-R2) groups is independently C1-C4 alkylene, R3 groups are independently C1-C4 alkylene, R4 is C1-C4 alkyl, x and y are average numbers such that x+y is in the range from 0 to about 60, and A- is an agriculturally acceptable anion; or (c) (see formula III) wherein R1 is a straight or branched chain C6 to about C22 alkyl, aryl or alkylaxyl group, m is an average number from 1 to about 10, R2 in each of the m (O-R2) groups is independently C1-C4 alkylene, R3 groups are independently C1-C4 alkylene, and x and y are average numbers such that x+y is in the range range 2 to about 60.
