摘要:
Herbicidal compositions are provided which cause rapid symptomology while delivering long term control of regrowth of plants. The herbicidal concentrate compositions comprise N-phosphonomethylglycine or a herbicidal derivative thereof, an auxin herbicide or a herbicidal derivative thereof, and at least one surfactant. Also provided is a method for killing or controlling the growth of certain plants by contacting the foliage of the plants with the diluted concentrate composition.
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.
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:
The present invention generally relates to herbicidal compositions comprising a herbicide, an etheramine alkoxylate surfactant, an alkylamine alkoxylate surfactant having a high degree of alkoxylation and compatibilizer comprising, in some embodiments, an alkylamine alkoxylate surfactant having a low degree of alkoxylation or an alkylpolyglucoside surfactant. The herbicidal compositions are herbicidally efficacious and cause low eye irritation and low crop injury.
