Transparent liquid preparation of pesticide and preparation method for transparent liquid preparation

Abstract

The invention discloses a transparent liquid preparation of a pesticide. The transparent liquid preparation is prepared from 1 to 30 percent of a component A, 2 to 70 percent of a component B and the balance of another component and / or an excipient, wherein the component A is myclobutanil and / or triadimefon, and the component B is ethylene glycol diacetate. The transparent liquid preparation is missible oil, oil, an oil spray, a hot fogging concentrate, a smoke agent, ultralow-volume liquid, a soluble concentrate or microemulsion. The transparent liquid preparation provided by the invention can be used for preventing and controlling diseases of field food crops such as wheat, rice and corns and crops such as fruit trees, vegetables and cotton as a normal-volume, low-volume and ultra-volume spray.

Description

technical field [0001] The invention belongs to the technical field of pesticide processing, in particular to the processing and production of pesticide transparent liquid preparations. Background technique [0002] Pesticide transparent liquid preparations refer to transparent liquids observed with the naked eye within the normal use temperature range of pesticides (the use temperature range of pesticide preparations is generally considered to be between 0°C and 50°C), even if they are solid, semi-solid, turbid liquid or liquid at other temperatures. For emulsions, the formulation should return to transparency once the temperature reaches the normal use range. Such pesticide preparations include emulsifiable concentrates, oils, soluble solutions, ultra-low volume liquids (ultra-low volume sprays, ultra-low volume formulations, ULV), microemulsions, oil mist, thermal mist, water, etc. [0003] Triazole fungicides have the characteristics of high efficiency, low toxicity, lo...

AI Technical Summary

Problems solved by technology

[0006] The present invention is by selecting a kind of ethylene glycol diacetate (EGDA) as the solvent or co-solvent of triadimefon or myclobutanil, cooperates other environment-friendly solvents to use, does not need light aromatic hydrocarbon solvent (benzene, toluene, xylene), Harmful solvents such as methanol and dimethylformamide (DMF) solve the problems of low flash point, poor safety, low solubility, low temperature crystallization, poor compatibility stability, and corrosion to bottle materials.
