Problems solved by technology

[0004] To control or prevent the occurrence of pests, people often use pesticides on crops. With the enhancement of people's awareness of environmental protection, the share of environmentally friendly formulations such as granules has gradually replaced the traditional formulations such as emulsifiable concentrate and wettable powder. However, conventional pesticide granules Pesticides often have deviations in drug efficacy, and the duration of effect is not long, requiring repeated application of pesticides, which increases the number of times and dosage of pesticides used. Such repeated and large-scale use of pesticides will not only increase the cost of pesticides, but also affect the environment. will also have some impact
[0005] In order to solve the problem of short duration of pesticide granules, people use pesticide slow-release technology, that is, physical or chemical methods, so that pesticides can be released slowly, so as to achieve the purpose of prolonging the duration of pesticides

Abstract

The invention relates to a clothianidin granule and a preparing method thereof. Clothianidin accounts for 0.01%-10% of the total mass of the granule, and the balance is assistants. The clothianidin granule has the effect of slow release, the using effect is improved, and the lasting period is prolonged.

Description

technical field [0001] The invention belongs to the technical field of chemical technology, and in particular relates to a preparation method and application of clothianidin granules with slow-release effect. [0002] technical background [0003] Clothianidin is a kind of neonicotinoid insecticide, which is a kind of efficient, safe and highly selective insecticide. Its action is similar to that of nicotinic acetylcholine receptor, and it has contact killing, stomach poisoning and systemic activity. It is mainly used as an insecticide for preventing and controlling aphids, leafhoppers, thrips, planthoppers and other pests of Hemiptera, Coleoptera, Diptera and some Lepidoptera on rice, vegetables, fruit trees and other crops. It has the advantages of broad spectrum, less dosage, low toxicity, no harm to crops, no cross-resistance with conventional pesticides, etc. It has excellent systemic and osmotic effects, and is another variety to replace highly toxic organophosphorus pe...
