Problems solved by technology

my country has 16 compounding certificates for the registration of glyphosate compounding. Glyphosate compounding has achieved certain results, but all of the registered compound herbicides are chemical agents, and the amount of chemical pesticide components increases, which is difficult to degrade , leading to increasingly serious problems such as pesticide residues, plant damage, and environmental pollution

Abstract

The invention discloses a glyphosate compound water preparation, the main active ingredients of which are: glyphosate, walnut leaf water extract, vinca alkaloid; the compound water preparation includes the following raw materials in parts by weight: glyphosate 15-20g, 5-8g of walnut leaf water extract, 4-6g of vinca alkaloids, 1-2g of solubilizer, 0.5-1g of stabilizer, 500-600mL of water; at the same time, the preparation method of the above-mentioned glyphosate compound water agent is also disclosed, and Application of glyphosate compound water agent. The invention not only reduces the amount of chemical pesticides used, but also makes up for the shortcomings of slow biological pesticides and high cost of use, not only effectively protects crops from pests, but also avoids a lot of pollution and damage to the ecological environment. The purpose of expanding the weeding spectrum, increasing the weeding effect and accelerating the weeding speed of glyphosate is realized, and has a good market prospect.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, and in particular relates to a glyphosate compound water preparation and a preparation method and application thereof. Background technique [0002] Glyphosate, chemical name is N-(phosphomethyl)glycine, chemical formula C 3 H 8 NO 5 P, is an environment-friendly systemic and conductive broad-spectrum herbicide, which has a very good effect on perennial weeds and biennial grass weeds. Due to its excellent herbicidal activity, broad herbicidal spectrum, low soil residues, long weed control time, and the large-scale cultivation of herbicide-resistant genetically modified crops, glyphosate has become the world's No. 1 herbicide by sales. Variety. However, in recent years, the long-term, single, continuous and extensive use of glyphosate has led to an increase of resistant weed individuals and populations year by year, reducing the control effect of herbicides and increasing the co...
