Glyphosate oil suspending agent and preparation method thereof

Abstract

The invention relates to a glyphosate oil suspending agent, comprising the following components of, by weight, 1-60% of glyphosate, 10%-80% of plant oil, 1-15% of a dispersing agent, 1-10% of a thickening agent, 2%-10% of a stabilizing agent, 10-40% of an emulsifying agent, 0.1-5% of a pH conditioning agent and 1-5% of a synergist. The preparation method comprises the following steps of 1) mixing and dispersing 1-60% of glyphosate, 10-40% of the emulsifying agent, 1-10% of the thickening agent and 1-15% of the dispersing agent; 2) sand grinding for 1.5-2.5 h via a sand mill, cooling with circulating water to make the temperature of the mixture no higher than 50 DEG C and the particle size no larger than 5 micrometers; 3) adding the grinded mixture into a preparation kettle, adding 0.1-5% of the pH conditioning agent, 1-5% of the synergist, 2%-10% of the stabilizing agent and 10%-80% of the plant oil, and stirring uniformly; and 4) filtering the prepared product with a 30-50 mesh filtering screen, and thus the final product is obtained. The method has the characteristics of low filling consumption, environmental protection, high efficiency and board spectrum.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a glyphosate oil suspension and a preparation method thereof. Background technique [0002] Citrus is one of the main economic crops in my country. The weeds in citrus orchards mainly include A. chinensis, Indian sage, squirrel (Qingming grass), chickweed, pinnata, wood sorrel, etc., and a small amount of perennial weeds Grasses such as malan, flower point grass, hollow lotus seed grass (water peanut) and so on. [0003] Weeds in citrus orchards are extremely vigorous, and some seeds can still germinate after 20 years in the soil. General weeds have the characteristics of early maturity, irregularity, and segmental emergence, which are not conducive to control, and many weeds can come back from the dead, especially perennial weeds. In addition, weeds also have amazing reproductive capacity, and the number of seeds produced by most weeds is several times or even hundreds of time...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a kind of glyphosate oil suspension concentrate and preparation method thereof, overcome the defect that glyphosate powder needs to consume a large amount of filler and cause serious pollution to the environment, and overcome grass Glyphosate water has the disadvantage of large drug loss, and has the characteristics of less filler consumption, environmental protection and high efficiency and broad spectrum
