Problems solved by technology

[0002] At present, beta-cypermethrin and chlorpyrifos are often used alone as insecticides, but after a long time, pests such as cotton bollworm, aphids, cabbage caterpillars and other pests will develop high resistance to them, which seriously affects the insecticidal effect and has a relatively large impact on agricultural production. severe impact

Abstract

The invention relates to a compound preparation of efficient cypermethrin and chlorpyrifos. The compound preparation is an emulsifiable solution and comprises the following effective components in percentage by weight: 1%-6% of the efficient cypermethrin, 20%-60% of chlorpyrifos, and the balance of emulsifiers and organic solvents added to 100%. The compound preparation of the efficient cypermethrin and the chlorpyrifos has higher synergistic and complementary effect and good killing effect especially on resistance pests, i.e. cotton bollworms, aphids, cabbage caterpillars, and the like which have high pesticide resistance on the cypermethrin, and also has contact poisoning action, stomach poisoning action and osmosis action; and in addition, the invention has the advantages of high knockdown speed, broad insecticidal spectrum, lower toxicity, long persistent period, and the like and has safety on crops and lower toxicity on human and livestock.

Description

technical field [0001] The invention relates to an insecticide, in particular to a compound preparation of beta-cypermethrin and chlorpyrifos. Background technique [0002] At present, beta-cypermethrin and chlorpyrifos are often used alone as insecticides, but after a long time, pests such as cotton bollworm, aphids, cabbage caterpillars and other pests will develop high resistance to them, which seriously affects the insecticidal effect and has a relatively large impact on agricultural production. serious impact. Contents of the invention [0003] In order to solve the resistance of pests to beta-cypermethrin and chlorpyrifos and expand the insecticidal range of the preparation, the invention provides a compound preparation of beta-cypermethrin and chlorpyrifos. [0004] Beta-cypermethrin is a pyrethroid insecticide with high biological activity. It is a high-efficiency isomer of cypermethrin. It has contact and stomach toxicity, wide insecticidal spectrum and fast knoc...
