Abstract

The invention specifically relates to a water dispersible granule containing malathion and application thereof, belonging to the technical field of complex formulation of pesticides. Effective components of the water dispersible granule are high-efficiency trans-cypermethrin and malathion, and a weight ratio of malathion to high-efficiency trans-cypermethrin is 1: 5 to 1: 20. The water dispersible granule utmostly alleviates the problem of drug resistance of insects at present, so the application amounts of pesticides are reduced, influence on the environment is abated, and the water dispersible granule is consistent with the tendency of greenness and environment friendliness of in the future society and exerts an optimal crop protection effect.

Description

Technical field [0001] The invention belongs to the technical field of pesticide and insecticide compounding, and specifically relates to a water dispersible granule containing malathion and its application. Background technique [0002] Malathion [0003] English common name malathion [0004] Toxicity Malathion is a low-toxic pesticide. [0005] The scope of application is suitable for controlling pests on crops such as tobacco, tea and mulberry. It can also be used to control warehouse pests. [0006] Malathion has good contact killing, stomach toxicity and certain fumigation effect, without systemic effect. After entering the insect body, it is oxidized to malathion, which can play a more toxic effect. When entering the warm-blooded animal, it is hydrolyzed by the carboxylesterase that is not in the insect body, thus losing its toxicity. Malathion has low toxicity and short residual effect. It is effective against pests of piercing and sucking mouthparts and chewing mouthparts. ...
