Abstract

The invention discloses a solvent composition for preparing an organic phosphorus pesticide liquid preparation, which is composed of triethyl phosphate and eucalyptus oil in a mass ratio of 1:10-5:1; and the composition accounts for 5-90 wt% of the organic phosphorus liquid preparation. When being directly mixed with pesticide effective ingredients and surfactant to prepare an organic phosphorus pesticide liquid preparation, the solvent composition can greatly enhance the stability of the effective ingredients in the preparation. The solvent composition can substitute common aromatic hydrocarbon and alcohol solvent in the organic phosphorus liquid preparation, and has the advantages of high environmental protection property and high production safety. The solvent composition has favorable solubility for diazinon, quinalphos, triazophos, phoxim, chlorpyrifos and Dufulin, has favorable stabilizing effect, and meamwhile, has the function of synergic disinsection and sterilization.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a solvent composition for preparing organophosphorus pesticide liquid preparations. Background technique [0002] Organophosphorus pesticides are a class of pesticides that are widely used in my country and are used in large quantities. There are many types of them. They are mainly used to kill insects and mites in agriculture, and they also have bactericidal effects. However, in the current technology, organophosphorus pesticides mostly use a large amount of aromatic hydrocarbons, alcohol solvents, ketone solvents, and N,N-dimethylformamide as solvents to prepare emulsifiable concentrates, emulsions in water, microemulsions, etc., which are usually poor in stability and easy to alcohol. Decomposition and hydrolysis, and the toxicity of these solvents has a great impact on the environment. [0003] Chinese application CN1062637 discloses a kind of dimethrin emulsifiable conce...
