Preparation method of glufosinate-ammonium -2, 4-drop soluble concentrate

Abstract

The invention discloses a preparation method of glufosinate-ammonium -2, 4-drop soluble concentrate. The preparation method of the glufosinate-ammonium-2, 4-drop soluble concentrate comprises the following steps of: mixing 2, 4-drop active compound with a dimethylamine aqueous solution to generate 2, 4-drop dimethylamine salt, accurately weighing glufosinate-ammonium active compound, propylene glycol monomethyl ether, ethylene glycol and dodecyl ether sulfuric acid, adding water, mixing and stirring, and standing to obtain the glufosinate-ammonium 2, 4-drop soluble concentrate, wherein the mass ratio of the 2, 4-drop active compound to the dimethylamine to the glufosinate-ammonium to the propylene glycol monomethyl ether to the ethylene glycol to the dodecyl ether sulfuric acid to the water is (1.77-2.40): (1.02-1.05): (9.47-11.58): (0.75-0.85): (4.85-5.15): (3.8-4.2): (78.34-74.77). According to the invention, 2, 4-drops and glufosinate-ammonium are mixed according to a proper ratio to prepare glufosinate-ammonium 2, 4-drops soluble concentrate, so that the generation of herbicide resistance of weeds is delayed, the weeding range is expanded, the pesticide effect is improved, thedosage is reduced, the economic cost is saved, and the effective storage life of the glufosinate-ammonium 2, 4-drops soluble concentrate is more than two years.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a preparation method of glufosinate-ammonium-2,4 drops soluble agent. Background technique [0002] Both 2 and 4 drops and glufosinate-ammonium are herbicides, the concentration of 2 and 4 drops is usually 70%, and the concentration of glufosinate-ammonium is usually 23%. 2,4-D is the world's first industrialized selective and high-efficiency organic herbicide, and has been one of the main herbicide varieties in the world because of its low dosage and low cost. However, 2,4-D is moderately acutely toxic to many animals. It can stimulate human cholinergic nerves, reduce insulin secretion, inhibit the formation of adrenocortical hormone, reduce smooth muscle tension, and increase striated muscle tension. The substance is irritating to the skin, respiratory tract and eyes and in high concentrations the substance may have effects on the nervous system. Nervous system symptom...

AI Technical Summary

Problems solved by technology

[0004] Therefore, when using 2, 4 drops and glufosinate-ammonium to kill weeds, due to its high concentration, it is easy to cause poisoning of humans and animals, and glufosinate-ammonium is easy to continue to accumulate in the environment, causing continuous pollution

In addition, the use of glufosinate and 2,4 drops alone can easily make weeds resistant
