Glyphosate composite soluble concentrate and preparation method thereof

Abstract

The invention belongs to the technical field of pesticides, and discloses a glyphosate composite soluble concentrate which comprises effective components and other components, wherein the effective components comprise glyphosate and pyridyloxyacetic acid herbicides, and the other components comprise organic amine, a cationic surfactant, water and chemically acceptable components. The pyridyloxyacetic acid herbicides comprise any one of fluroxypyr and triclopyr; the organic amine is tertiary amine type organic amine with the molecular weight of 100-300; and the cationic surface active agent is fatty acid acylamino type Gemini. The glyphosate composite soluble concentrate prepared by the preparation method disclosed by the invention is good in low-temperature stability, free from icing and caking at-16 DEG C, good in fluidity and free from crystallization; the high-temperature stability is good, the preparation is not turbid at 70 DEG C or above, and the surfactant is not inactivated; the freeze-thaw stability is good, and the normal storage stability is good; and the preparation process is simple, inorganic base is not used in the production process, production equipment is friendly, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a glyphosate compound soluble agent and a preparation method thereof. Background technique [0002] Glyphosate is a non-selective, non-residual herbicide that is effective against perennial root weeds. It mainly inhibits enolpyruvylshikisikiphosphate synthase in plants, thereby inhibiting the transformation of shikimicin to phenylalanine. The transformation of acid, tyrosine and tryptophan interferes with protein synthesis, leading to plant death. Due to the long-term single use of glyphosate in a large area, many weeds have developed resistance. At the same time, the weeds in non-cultivated land are complex, not only annual and perennial weeds are mixed, herbs, vines and shrubs, but also weeds are uneven, so when the herbicide species are used alone, they will show some defects and limitations. [0003] In order to delay the development of weeds' resistance to glyphosate, gly...
