Embodiment 1

[0031] The preparation of the synergistic composition of the present invention, formula (mass percentage): isomeric alcohol polyoxyethylene ether nonionic surfactant ANTAROX EP26 (referred to as EP26, purchased from Solvay, the same below) 20%; fatty alcohol polyoxyethylene Vinyl ether polymer emulsifier N-300 (referred to as N-300, purchased from Shantou Daqian High-tech Research Center Co., Ltd., the same below) 40%; antifreeze agent glycerin 5%; complexing agent EDTA-ammonium salt 1%; Deionized water makes up 100%.

[0032] The preparation method is to weigh deionized water according to the formula ratio, heat the reaction kettle to 40°C-50°C, and add complexing agent EDTA-ammonium salt sodium benzoate, antifreeze agent glycerin and functional polymer according to the formula ratio under constant stirring. Additive N-300; Stir and mix well, add EP26, continue to stir and mix evenly, the reaction kettle is cooled to room temperature 25-30°C, and the product is a synergistic ...

Embodiment 2

[0034] Synergistic composition formula (mass percentage): EP26 10%; N-300 10%; antifreeze agent glycerin 1%; complexing agent EDTA-ammonium salt 1%; deionized water to make up 100%.

[0035] Preparation method, weigh deionized water in proportion, heat to 40°C-50°C, add complexing agent EDTA-ammonium salt, antifreeze glycerin and N-300 in proportion under constant stirring, mix well and then add EP26 , continue to stir and mix evenly, the reaction kettle is cooled to room temperature, and the product is a synergistic composition.

Embodiment 3

Abstract

The invention relates to a synergistic composition of herbicide glufosinate-ammonium, in particular to a composition capable of improving the wetting permeability and moisture retention performance of a spray liquid of glufosinate-ammonium. The composition mainly comprises an isomeric alcohol polyoxyethylene ether nonionic surfactant EP26, a fatty alcohol polyoxyethylene ether polymer emulsifier N-300, an anti-freezing agent, a complexing agent and deionized water. 0.5%-2.0% (mass percentage) of the synergistic composition is added into the spray liquid of glufosinate-ammonium, so that the wetting permeability and moisture retention performance of the spray liquid can be obviously improved, the glufosinate-ammonium medicament is promoted to be absorbed by weeds more quickly, the adverse effect of environment humidity on the pesticide effect is reduced, and the fast-acting property and the comprehensive prevention and control effect of the glufosinate-ammonium on the weeds are improved.

Description

technical field [0001] The invention relates to a synergistic composition of the herbicide glufosinate-ammonium, in particular to a composition capable of improving the wetting permeability and moisturizing performance of the glufosinate-ammonium spray liquid. Background technique [0002] Paraquat (the chemical name is 1-1-dimethyl-4-4-bipyridine cationic salt) is a fast-killing herbicide. Generally, it can take effect within a few hours of spraying and make it dead. However, paraquat is highly toxic and harmful to humans and animals. There is no specific antidote, and the mortality rate of oral poisoning is over 90%. It has been listed as a prohibited drug. my country will ban paraquat related products from the domestic market from September 21, 2020. . The effects of glyphosate and glufosinate-ammonium are not as good as the quick-acting of paraquat. Glyphosate generally takes 7-9 days to take effect, and dead grass takes about 15 days. Glufosinate-ammonium generally take...
