Hot fogging concentrate containing propiconazole and chlorpyrifos and preparation method thereof

Abstract

The invention discloses a hot fogging concentrate containing propiconazole and chlorpyrifos and a preparation method thereof. The hot fogging concentrate comprises the following raw material components in percentage by weight: 10 to 50 percent of chlorpyrifos, 1 to 20 percent of propiconazole, 5 to 30 percent of solvent, 1 to 15 percent of surface active agent, 0.1 to 5 percent of thickening agent, 1 to 8 percent of hot fogging concentrate density regulator, 1 to 8 percent of freeze proof agent, 0.1 to 1 percent of antifoaming agent, and the balance of water. The prepared hot fogging concentrate of the invention is a broad-spectrum sterilization and desinsection composition and is used with a hot fogging device for preventing and treating plant diseases and pests, has high application efficiency and good drug effect, is suitable for the middle and low stalk plants such as rapes, corns, wheat and the like, has less environment pollution, can also reduce the labor intensity of the operators and reduce contamination risk, and can completely solve the water using problem of preventing and treating plant diseases and pests in the water-deficient area.

Description

Technical field [0001] The invention relates to the field of pesticides for the prevention and control of plant diseases and insect pests, in particular to a hot mist containing propiconazole and chlorpyrifos and a preparation method. Background technique [0002] At present, the products of propiconazole and chlorpyrifos produced at home and abroad are all emulsifiable concentrates, water emulsions or suspensions, which are mainly formulated with toluene and xylene solvents with lower boiling points. It is difficult for them to directly use the hot mist machine to perform efficient operations. They can only use other methods to apply the pesticide. During the application process, a large amount of fresh water must be mixed to form an emulsion and then sprayed. The formed water mist is seriously lost on the plants and is not resistant to rain washing. The efficacy time is short, and at the same time it is harmful to the environment and operators; the large amount of dilution wate...

AI Technical Summary

Problems solved by technology

It is difficult for them to directly use the hot fog machine for efficient operations, so they can only use other methods to apply pesticides. In the process of spraying pesticides, they need to mix a large amount of fresh water to form emulsions and then spray them. The formed water mist is seriously lost on the plants and is not resistant to rain. The drug effect time is short, and at the same time, it is highly toxic to the environment and operators; the amount of dilution water is large, which increases the labor intensity and working time, and the work efficiency is low.

Thermal mist has been studied abroad earlier, but its development is slow. Most of its applications are in sanitation or epidemic prevention of forests and greenhouse crops. In the 1970s and 1980s, several thermal sprays appeared in forest and rubber pest control. However, so far So far, thermal sprays can only be used for tall and shaded plants (such as trees, fruit trees) or relatively sealed spaces (such as warehouses, greenhouses, etc.) Without special treatment, the hot mist of active ingredients is easy to diffuse into the atmosphere with the updraft, which not only reduces the efficacy of the medicine, but also easily causes environmental pollution
