摘要
(US6908882) 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 C<SUB>8-24 </SUB>linear or branched, saturated or unsaturated hydrocarbyl group, and the second surfactant has the formula <?in-line-formulae description="In-line Formulae" end="lead"?>R-CO-NR'-(CR'<SUB>2</SUB>)<SUB>n</SUB>-COOM<?in-line-formulae description="In-line Formulae" end="tail"?> where R is a C<SUB>7-23 </SUB>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, C<SUB>1-4 </SUB>alkyl or a group -(CH<SUB>2</SUB>)<SUB>m</SUB>-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 -(CH<SUB>2</SUB>)<SUB>m</SUB>-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.

(US6908882) 1. A method of enhancing herbicidal activity of a glyphosate herbicide, comprising adding to said glyphosate herbicide a first surfactant and a second surfactant at a weight ratio of total surfactant to form a composition consisting essentially of glyphosate, a first surfactant, and a second surfactant to glyphosate acid equivalent of about 1.30 to about 2:1, wherein said first surfactant has a chemical structure comprising a cationic or protonatable amino group and a C8-24 hydrocarbyl group, and said second surfactant has the chemical formula    R -- CO -- NR' -- (CR'2)n -- COOM where R is a C7-23 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 and the weight ratio of said first surfactant to said second surfactant being about 1:10 to about 10:1. 2. The method of claim 1 wherein said first surfactant is selected from: a tertiary alkylamine and alkyletheramine;  polyoxyethylene tertiary alkylamine and alkyletheramine;  quaternary ammonium;  pyridine;  imidazoline;  polyoxyethylene alkylamine and alkyletheramine oxide;  an alkylbetaine;  and alkyl diamine and a polyoxyethylene alkyl diamine. 3.
