Profenofos emulsifiable granules and preparation method thereof

Abstract

The invention relates to profenofos emulsifiable granules and a preparation method thereof, and relates to an agricultural bactericide. The profenofos emulsifiable granules comprise the following raw materials in percentage by weight: 20%-60% of profenofos, 5%-10% of emulsifying agent, 8%-12% of water soluble polymer, and the balance of carriers. The preparation method comprises the following steps: mixing liquid profenofos and the emulsifying agent uniformly firstly; adding profenofos after mixing into a water solution of the water soluble polymer, and mixing uniformly, thus viscous emulsion is obtained; then adding the carriers into the viscous emulsion, thus a pre-granulating mixture is obtained; and finally granulating and drying. The granules provided by the invention can achieve good effect at low concentration, have quick acting and duration, and can maintain the effect for a long time; and the granules have strong internal absorption property and permeability, and can kill leaf rollers in leaves.

Description

Technical field [0001] The present invention involves a pesticide pesticide, especially the preparation method of a proprobosiopodicized granules 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,...

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
