Abstract

The invention provides a high-content ammonium glyhosate herbicide and a preparation method thereof. The high-content ammonium glyhosate herbicide comprises the following raw materials by mass: 80 to82 parts of glyphosate, 9.25 to 9.45 parts of liquefied ammonia, 8.5 to 8.8 parts of auxiliary agents and 4.2 to 4.5 parts of ammonium sulfate, wherein the auxiliary agents are composed of, by weight,0 to 3 parts of antimony potassium tartrate, 0 to 2 parts of copper sulfate, 0 to 1 part of leucine, 0 to 3 parts of alpha-curcumene, 0 to 4 parts of caffeic acid and 0 to 3 parts of fatty alcohol ether phosphate. The preparation method for the herbicide comprises the following steps: feeding of glyphosate and ammonium sulfate; dropwise addition of liquefied ammonia; heat-preserved intermediate control; addition of the auxiliary agents; granulation and shaping; and dehydration. The yield of the herbicide prepared in the invention is 94.3-99.6%.

Description

technical field [0001] The invention relates to a high-content ammonium glyphosate herbicide and a preparation method thereof, belonging to the technical field of pesticides. Background technique [0002] Glyphosate ammonium salt herbicide is one of the main herbicides on the market; glyphosate is a systemic conduction chronic broad-spectrum herbicide, which mainly inhibits enolacetonyl shikimelin phosphate synthase in the body, thereby inhibiting The conversion of shikime to phenylalanine, tyrosine, and tryptophan interferes with protein synthesis leading to plant death. [0003] Glyphosate is absorbed by the stems and leaves and then transmitted to various parts of the plant. It can control more than 40 families of plants such as monocots and dicotyledons, annuals and perennials, herbs and shrubs. Glyphosate quickly combines with metal ions such as iron and aluminum to lose its activity after entering the soil, and has no adverse effects on the seeds and soil microorganis...
