    摘要: Methods of reducing injury to crop foliage and achieving weed control using encapsulated acetamide herbicides are described. Herbicidal microcapsules comprising herbicide core material and a shell wall encapsulating the core material are also described. The microcapsules provide reduced crop injury through controlled herbicide release.

    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.
