Profenofos emulsion in water and preparation method thereof

Abstract

The invention discloses profenofos emulsion in water and a preparation method thereof, and relates to a pesticide. The emulsion in water comprises the following raw materials in part by weight: 20 to 60 parts of profenofos, 8 to 12 parts of cosolvent, 5 to 10 parts of emulsifier, 1 to 2 parts of anti-freezing agent, and the balance of water serving as a carrier. The invention has the advantage of providing the emulsion in water with a little organic solvent; when the emulsion in water is used, the emulsion can be totally emulsified by adding water; and the pesticide effect of the emulsion in water is totally superior to that of a profenofos missible oil formulation with the same effective ingredient. The emulsion in water with low concentration can achieve high effect, has quick response and persistent effect, and can keep the effect for a long term. The emulsion in water has strong internal absorption and osmotic force, and can kill leaf folders. The emulsifier has high hydrophile-lipophile balance (HLB) value and is not easily salted out.

Description

Technical field [0001] The present invention involves a pesticide pesticide, especially the preparation method of a proprobosiopodine emulsion and proprob present. Background technique [0002] Pneumine is a new type of organic phosphorus pesticide, which has the characteristics of high efficiency, broad -spectrum, internal suction, low residue and other characteristics. It is acetylcholine inhibitor. It has the effects of touching and gastric poisoning.Harmful insects and mites.Because proprob present is still effective in cotton pests that produce resistance to other organic phosphorus and chrysanthemums to be eliminated, and the effect of vegetable diseases and insect pests is obvious. Therefore, the amount of use is increasing.Direct poisoning, but the molecular structure of proprivetosios is relatively stable, and it is difficult to be decomposed and excreted in the organism. Long -term consumption of contaminated vegetables can cause diseases such as cancer, infertility, en...

AI Technical Summary

Problems solved by technology

Because profenofos is still effective to other cotton pests that are resistant to organophosphorus and pyrethroids, and has obvious effects in the control of vegetable diseases and insect pests, so the amount of use is increasing day by day, although a small amount of profenofos residues will not cause immediate harm to the human body. Direct poisoning, but the molecular structure of profenofos is relatively stable, and it is difficult to be metabolized and excreted in the living body. Long-term consumption of contaminated vegetables can lead to diseases such as cancer, infertility, and endocrine disorders. Harm the nerve center, resulting in convulsions and death

At present, profenofos is mostly emulsifiable concentrate (EC) products, and the solvents used are mainly aromatic hydrocarbons such as toluene and xylene, which pollute the environment and waste a lot of petroleum resources, which do not meet the requirements and trends of sustainable agricultural development
