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.

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.

Description

(1) Technical field [0001] The invention relates to a beta-cypermethrin granule, in particular to a safe and reliable insect slow-release insecticidal granule. (2) Background technology [0002] Beta-cypermethrin is a traditional product. It has high stomach toxicity and contact killing effect on insects. It knocks down quickly and has a wide insecticidal spectrum. This product has been officially registered. The content ranges from 0.1 to 10%. , wettable powder, smoke agent, etc., mainly to control aphids, cabbage caterpillars, etc. 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 the actual use process, if it is used improperly...
