A kind of preparation method and application of rosin source pesticide synergist

Abstract

The invention discloses a preparation method and application of a rosin-source pesticide synergist. The preparation method includes: adding an alcohol solution into rosin fragments for dissolving to obtain a rosin solution; adding an alkali solution into the rosin fragments for saponification to obtain a saponified solution; adding the rosin solution into the saponified solution, stirring and mixing well, adjusting pH, adding an emulsifier for emulsifying, adding the alcohol solution, and filtering to obtain the synergist. Raw materials are low in cost and easy to get, a preparation path is simple, reaction conditions are mild, and the preparation method is energy-saving, environment-friendly, low in requirements on equipment, simple, convenient and safe to operate, low in cost, high in yield and easy for industrialized production. The synergist obtained by the preparation method can improve wetting capability and adhesion force of pesticide liquid; after the synergist is compounded with various pesticides like insecticide, miticide and herbicide, pesticide efficacy is improved remarkably, pesticide consumption is lowered, and the synergist has the advantages of broad-spectrum high efficiency and low toxicity and safety to humans and livestock, and is suitable for large-scale popularization and application and remarkable in economic and social benefit.

Description

technical field [0001] The invention relates to a pesticide synergist, in particular to a synergist capable of improving the efficacy of pesticides such as known insecticides, acaricides and herbicides, and a preparation method and application thereof. Background technique [0002] my country is a large agricultural production country, and the development of agriculture is inseparable from pesticides. However, while pesticides make great contributions to agricultural development, they also pollute the natural environment. Various field efficacy experiments over the past few decades have shown that most of the currently used pesticides have low wettability and adhesion. Into the atmosphere, it seriously damages the balance of agricultural ecology and brings harm to humans and livestock. To change this situation, efforts should be made to develop new pesticides with high efficiency, low toxicity and low residue, and to limit and eliminate the use of highly toxic pesticides. ...

AI Technical Summary

Problems solved by technology

Dimethyldioxybenzene derivatives, synergistic ether, synergistic phosphorus, synergistic sulfone, etc. are commonly used synergists at present. However, these traditional synergists have disadvantages such as long synthetic routes, high prices, and environmental pollution. , so new, low toxicity, environmental protection, cheap, especially the green pesticide synergist derived from natural products is the ideal synergist needed by farmers, and it is one of the goals that require the majority of scientific research workers to focus on

my country is rich in rosin resources and is the world's largest producer and exporter of rosin. At present, my country's rosin is basically still in the stage of selling raw materials, and there are fewer varieties of deep-processed products, about 30 kinds, and the raw materials used for deep processing account for only 70%. %, products with low technological content and low added value
