Embodiment 1

[0031] Preparation, formulation (mass percent) of the present invention: isomeric alcohol polyoxyethylene ether non ionic surfactant Antarox EP26 (EP26, purchased from Soli, the following) 20%; fat alcohol polyoxia Vinyl ether polymer emulsifier N-300 (referred to as N-300, purchased from Shantou Daqian High-tech Research Center Co., Ltd., the following) 40%; antifreeze propanol 5%; complexing agent EDTA-ammonium salt 1%; Deion water is 100%.

[0032] The preparation method is presented according to the proportion of the ion water, and the reaction kettle is heated to 40 ° C to 50 ° C, and the complexing agent EDTA-ammonium brownzoate, antifreeze glycerol and functional polymer are added to the formulation ratio in conjunction. Adding N-300; mixed with EP26 after stirring, mixing EP26, continued to stir mix, and the reaction cooled to room temperature 25-30 ° C, the product is a synergistic composition.

Embodiment 2

[0034] Synergic composition formulation (mass percent): EP26 10%; N-300 10%; 1% antifreeze propylene glycol; complexing agent EDTA-ammonium salt 1%; deionized water Supplement 100%.

[0035] The preparation method, proportionally, ionized water, heated to 40 ° C to 50 ° C, and the complexing agent EDTA-ammonium salt, antifreeze glycerol and N-300 were added in the case of continuously stirring, and mixed with EP26 after mixing. Continue to stir mix and mix, and the reactor is cooled to room temperature, and the product is a synergistic composition.

Embodiment 3

[0037] Formulation of the synergistic composition (mass percent): EP26 40%; N-300 40%; antifreeze ethylene glycol 5%; complexing agent EDTA-ammonium salt 2%; deionized water Supplement 100%.

[0038] The preparation method, proportionally, ionized water, heated to 40 ° C to 50 ° C, and the complexing agent EDTA-ammonium salt, antifreeze ethylene glycol, and N-300 were added, mixed with EP26 after constant stirring. Continue to stir mix and mix, and the reactor is cooled to room temperature, and the product is a synergistic composition.

Abstract

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. The composition is mainly composed of isomeric alcohol polyoxyethylene ether nonionic surfactant EP26, fatty alcohol polyoxyethylene ether polymer emulsifier N-300, antifreeze agent, complexing agent and deionized water. Adding 0.5%-2.0% (mass percentage) of the synergistic composition of the present invention to the spray liquid of glufosinate-ammonium can obviously improve the wetting permeability and moisture retention performance of the spray liquid, and promote the faster dehydration of the glufosinate-ammonium medicament. Absorbed by weeds, reduce the adverse effect of environmental humidity on the efficacy of the drug, and improve the quick-acting and comprehensive control effects of glufosinate-ammonium on weeds.

Description

Technical field [0001] The present invention relates to a synergistic composition of a herbicide step ammonium phosphine, in particular a composition capable of improving the wetting permeability and moisturizing properties of the ammonium phosphine spray. Background technique [0002] Parafades (chemical names are 1-1-dimethyl-4-4-gyridine cationic salt) is a rapidly destroyed herbicide, in general, in a few hours, it can be seen. However, the brackmatism is strong to human animals, no effect is more than 90% of the oral poisoning. It has been listed as prohibiting the use of drugs, and my country has been banned from Baquadacia from September 21, 2020. . The effect of killing herbicide glyphosate and grass ammonium phosphine is not as good as the veraffle, glyphosate generally takes 7-9 days, and grass grass, grass, grass ammonium phosphine is generally 3-5 days. 7-10 days dead grass. When Baquad is prohibited, the market has a strong demand for rapidly infection, and there is ...
