Efficient and environmentally friendly clodinafop-propargyl emulsifiable concentrate and its preparation method and application

Abstract

The invention discloses efficient and environment-friendly clodinafop-propargyl missible oil as well as a preparation method and application thereof, and belongs to the field of a pesticide formulation. The efficient and environment-friendly clodinafop-propargyl missible oil is prepared from the following ingredients in percentage by weight: 1 to 30 percent of clodinafop-propargyl, 1 to 35 percentof compound emulsifiers, 1 to 20 percent of cosolvents, 0.25 to 7.5 percent of safeners and the balance of solvents. The composite missible oil is prepared from phenethylphenol polyoxyethylene ethersulfate, polyoxyethylene lauryl ether and polyethylene glycol aliphatic ester according to the weight ratio of 1:(1 to 5):(5 to 10). The efficient and environment-friendly clodinafop-propargyl missible oil has the advantages that the preparation ingredient system is reasonable; the emulsification effect is good; the environment pollution is reduced.

Description

technical field [0001] The invention relates to the field of pesticide formulations, in particular to a high-efficiency and environment-friendly clodinafop-propargyl emulsifiable concentrate and its preparation method and application. Background technique [0002] EC is one of the basic formulations of pesticides. It is a homogeneous transparent oily liquid prepared by dissolving the original pesticide in an organic solvent in a certain proportion, and then adding a certain amount of special pesticide emulsifier, which can form a relatively stable emulsion with water. This oily liquid is called EC. . [0003] Compared with other pesticide dosage forms, EC has the following characteristics: EC has wide adaptability to pesticide technical materials. Most of the technical pesticides, including solid or liquid pesticides, are insoluble or insoluble in water, but easily soluble in organic solvents such as xylene. A considerable part of the original drug is unstable in water, b...

AI Technical Summary

Problems solved by technology

[0004] With the extensive use of highly polluting toluene, xylene solvents, and some highly polluting emulsifiers in emulsifiable concentrates, the negative impact of emulsifiable concentrates on the environment has gradually emerged. There are disadvantages such as harm to people and the environment. During the use of pesticides, all of them enter the environment, which not only causes serious environmental pollution, but also damages human health, leading to problems such as chronic biological poisoning.
