    摘要： A method is provided of enhancing the herbicidal activity of a glyphosate herbicide, comprising adding to the glyphosate herbicide a mixture of a first surfactant and a second surfactant at a weight ratio of total surfactant to glyphosate of about 1:30 to about 2:1, wherein the first surfactant has a chemical structure comprising a cationic or protonatable amino group and a C8-24 linear or branched, saturated or unsaturated hydrocarbyl group, and the second surfactant has the formula R—CO—NR′—(CR′2)n—COOM where R is a C7-23 linear or branched, saturated or unsaturated hydrocarbyl group, n is 1 to 4, M is hydrogen or a cationic counterion, and R′ groups are each independently hydrogen, C1-4 alkyl or a group —(CH2)m—COOM where m is 1 to 4 and M is as defined immediately above, with the proviso that no more than one R′ group is such a group —(CH2)m—COOM; the weight ratio of the first to the second surfactant being about 1:10 to about 10:1. Also provided is a herbicidal composition prepared according to the above method. The first and second surfactants exhibit a synergistic interaction in enhancing herbicidal activity of the glyphosate herbicide.
