Low-foam type glufosinate ammonium auxiliary agent and preparation technology thereof

Abstract

The invention discloses a low-foam type glufosinate ammonium auxiliary agent and a preparation technology thereof. The low-foam type glufosinate ammonium auxiliary agent is prepared from the followingsubstances in percentage by mass: 5 to 20 percent of fatty alcohol polyoxyethylene ether, 5 to 15 percent of coconut oil fatty acyl diethanol amine phosphate, 20 to 50 percent of methyl stearate polyoxyethylene ether, 1 to 20 percent of disodium cocoyl monoethanolamide sulfosuccinate DMSS, 1 to 5 percent of PEG (Polyethylene Glycol) and the balance of de-ionized water; reasonable ratios and a reasonable preparation method are adopted, and surfactants with different functional groups including carboxyl, an ether group and the like are compounded under the condition that an original function ofherbicide is not damaged, and are concatenated at the optimal ratio, so that each surfactant can play a role better under the action of other surfactants; the attachment time of glufosinate ammoniumon crops can be prolonged, and the low-foam type glufosinate ammonium auxiliary agent has good permeation, wetting, adhesion and emulsification capabilities, a strong rainwater washing resisting capability and the like.

Description

technical field [0001] The invention relates to the technical field of herbicide auxiliaries, in particular to a low-foaming glufosinate adjuvant with strong rain washing resistance and good long-lasting effect and a preparation process thereof. Background technique [0002] Glufosinate-ammonium is a non-conductive herbicide with high efficiency, low toxicity, and environmental friendliness. It is easy to degrade in the soil, safe for crops, not easy to drift, has a wide herbicidal spectrum, high activity, and low dosage, which is environmentally friendly. The pressure is low, and it is the second largest herbicide-tolerant genetically modified crop in the world after glyphosate; especially with the rapid development of genetically modified technology, the planting of genetically modified herbicide-resistant crops has intensified this year, and the use of herbicide-tolerant Substantial increase; glufosinate-ammonium is an excellent killing herbicide, very suitable for resist...

AI Technical Summary

Problems solved by technology

[0003] In view of the good application prospects of glufosinate-ammonium pesticides, it is also very important to study its important component-adjuvant; the adjuvant itself has no biological activity, but it is an indispensable and important component in the formulation or application process; the adjuvant The role of the auxiliaries is to improve the physical and chemical properties of the pesticides, which can exert the efficacy of the pesticides to a large extent or provide safer and more efficient construction methods; The direction of serialization is developed to meet the needs of processing different formulations of pesticide varieties; among them, the tackifier is an additive that can increase the adhesion of glufosinate-ammonium to solid surfaces, improve the ability of pesticides to resist washing by rain, and improve the lasting effect. property; at present, the drug effect time of glufosinate-ammonium sold on the market is not too long, therefore, it is very necessary to research and invent an auxiliary agent that can improve drug effect and prolong drug effect time
