Abstract

The invention discloses a glyphosate compound aqueous agent. The glyphosate compound aqueous agent comprises the following main active components: glyphosate, a walnut leaf aqueous extract and catharanthus roseus alkaloid, and the compound aqueous agent is prepared from the following raw materials in parts by weight: 15 to 20g of glyphosate, 5 to 8g of walnut leaf water extract, 4 to 6g of catharanthus alkaloid, 1 to 2g of a solubilizer, 0.5 to 1g of a stabilizer and 500 to 600mL of water. Meanwhile, the invention further discloses a preparation method of the glyphosate compound aqueous solution and application of the glyphosate compound aqueous solution. The use amount of chemical pesticides is reduced, meanwhile, the defects that biological pesticides are slow in speed and high in use cost are overcome, crops are effectively protected from being invaded by pests, much pollution and damage to the ecological environment are avoided, the weeding spectrum is expanded, the weeding effect is improved, the weeding speed of glyphosate is increased, and the weeding composition 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 its preparation method and application. Background technique [0002] Glyphosate, the chemical name is N-(phosphomethyl)glycine, and the chemical formula is C 3 h 8 NO 5 P, is an environmentally friendly systemic conduction type 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 residue, long weed control time, and the mass planting of herbicide-resistant transgenic crops, glyphosate has become the world's No. 1 herbicide in sales Variety. However, in recent years, the long-term, single, continuous, and extensive use of glyphosate has led to an increase in resistant weed individuals and populations, reducing the control effect of herbicides and increasing the cost of weed control. ...
