2% high efficiency cypermethrin granules

Abstract

The invention discloses 2% high efficiency cypermethrin granules. The granules are prepared through steps that: high efficiency cypermethrin, sodium lignosulfonate, precipitated calcium carbonate and a pigment are adopted as raw materials; the raw materials are sufficiently stirred with quartz sand or river sand according to a standard formulation method, such that the granules are formed. The granules have a high killing activity against underground pests such as grubs and small cutworms. Through a coating technology, the product is processed into sustained-release granules. Therefore, controlling effect of the granules can be improved, effective duration of the granules can be prolonged, peasant burden can be reduced, and economic benefits can be brought in. The application method of the granules is furrow application with soil covering, or broadcasting, such that the security is improved.

AI Technical Summary

Problems solved by technology

The dosage forms of traditional registered products are mainly emulsifiable concentrates, wettable powders, and smoke agents. The application methods are mainly spraying and lighting to release smoke. They mainly control aphids and cabbage caterpillars. It has a great impact on the environment, and the country has begun to prohibit the registration of new emulsifiable concentrate preparations. In actual use, if it is used improperly, it will have a safety impact on the applicator

Moreover, the actual experimental results should be considered, and the scope of prevention and control objects should be relatively narrow.
