Spirotetramat containing granules, application and preparation method of spirotetramat containing granules

Abstract

The invention relates to spirotetramat containing granules, an application and a preparation method. The spirotetramat containing granules comprise components in percentage by weight as follows: 0.01%-3% of spirotetramat, 1%-15% of an auxiliary agent, 0.1%-2% of a sustained-release agent, 1%-6% of a disintegrating agent, 0.1%-5% of a binding agent, 0.1%-0.5% of a coating agent and the balance of a carrier. The spirotetramat containing granules are mainly used for controlling underground pests and aboveground pests on crops such as maize, peanuts, sugarcane and the like and have a good prevention effect, a long efficacy lasting period and an excellent effect.

Description

Technical field: [0001] The invention relates to a granule containing spirotetramat, its application and its preparation method. Background technique [0002] At present, granules are mainly used in domestic agricultural control of subterranean pests. The active ingredients are mainly highly toxic carbofuran, terbufos, methimen, etc. The use of these agents will have the following problems: [0003] 1. It is very harmful to producers and users. Due to the high toxicity of active ingredients, a large number of accidents of poisoning and death due to production and use of highly toxic agents occur every year, which seriously threatens the lives and health of producers and users. [0004] 2. The long residue period leads to excessive residues of agricultural products and seriously affects the price and quality of agricultural products. It has become a major obstacle to the production of pollution-free agricultural products in my country and affects people's health. Moreover, t...

AI Technical Summary

Problems solved by technology

[0003] 1. It is very harmful to producers and users. Due to the high toxicity of active ingredients, a large number of accidents due to poisoning and death of highly toxic agents in production and use occur every year, seriously threatening the lives and health of producers and users

[0004] 2. The long residue period leads to excessive residues of agricultural products, which seriously affects the price and quality of agricultural products. It has become a major obstacle to the production of pollution-free agricultural products in my country and affects people's health.

Moreover, a large number of highly toxic pesticides are used, causing serious damage to the environment and ecology

[0005] 3. The long-term single use of these highly toxic pesticides has increased the resistance of pests, so that farmers have to increase the amount of pesticides, which further increases the risk of excessive pesticide residues and poisoning, and increases the cost of pesticides for farmers

[0006] In recent years, granules with medium and low active ingredients such as avermectin, chlorpyrifos, acephate, etc. have also been gradually applied to agricultural production. Although the problems of high toxicity and excessive residues have been solved, the concentration of these active ingredients The action spectrum is narrow, which cannot meet the needs of farmers for medication, and the cost of use is relatively high
