Problems solved by technology

[0004] Although esterified animal and vegetable oils have the above characteristics, their polarity is very weak, and it is not easy to be emulsified and processed into pesticide spray auxiliaries. Therefore, it is currently necessary to find an emulsifier that can effectively esterify animal and vegetable oils

Abstract

The invention provides an emulsifier and an application thereof in processing of pesticide spray additives, and relates to the technical field of pesticide application. Preferably, the emulsifier is prepared from nonylphenol polyoxyethylene ether NP-4, castor oil polyoxyethylene ether EL-10, rosin polyethylene glycol citrate, N-sodium lauroyl sarcosine and sodium di-sec-octyl maleate sulfonate ina combined manner. The composition can effectively emulsify and esterify animal and vegetable oil, a pesticide spray auxiliary agent is processed from the composition, the pesticide spray auxiliary agent is added into a pesticide solution through barrel mixing, the physical properties of the pesticide solution can be improved, and the properties such as wettability, spreading property, permeability, evaporation resistance and viscosity are enhanced, so that the effective utilization rate of a pesticide is increased, and pesticide application reduction is realized. The field application tests show that when the addition amount of the pesticide spray additive is about 2-3%, the pesticide spray additive is relatively appropriate.

Description

technical field [0001] The invention relates to the technical field of pesticide application, in particular to an emulsifier and its application in the processing of pesticide spray auxiliaries. Background technique [0002] According to the actual situation in the field of pesticides, my country's agriculture and forestry cause huge losses every year due to pests and weeds. In order to control the occurrence and spread of various diseases, insects, insects and weeds, people have been mainly using chemical pesticides for a long time. Pesticides, as an important means of agricultural production, are crucial to disease prevention and pest control, and to promoting stable and high yields of food and agriculture. Over the years, due to the expansion of the sown area of ​​crops and the increasing difficulty of pest control, the use of pesticides has increased accordingly. According to statistics, the ratio of chemical control areas to the total control area in my country is as hi...
