Abstract

The invention relates to water-dispersible granules for preventing and treating red spider mite. In the water-dispersible granules, effective ingredients are allicin and avermectin, auxiliaries are octylphenol polyoxyethenyl ether sulfate, Chinese honey locust powder and ammonium sulfate, and a carrier is white carbon black. The water-dispersible granules have very good preventing and treating effects on the red spider mite on non-edible roses; the allicin and the avermectin are compounded, so that aiming at preventing and treating the red spider mite, an additive effect is achieved; the water-dispersible granules are high in effect taking speed and long in duration and do not affect non-target crops.

Description

technical field [0001] The invention relates to a water-dispersible granule for preventing and treating spider mite, in particular to a water-dispersible granule whose active ingredients are allicin and avermectin, which is used for preventing and treating red spider on non-edible roses, and belongs to the technical field of pesticides. Background technique [0002] Abamectin has stomach poisoning and contact killing effects on mites and insects, but cannot kill eggs. The mechanism of action is different from general insecticides in that it interferes with neurophysiological activities and stimulates the release of GABA, which inhibits nerve conduction in arthropods. Acarid adults, nymphs and insect larvae will appear paralyzed symptoms after contact with avermectin, do not move, do not feed, and die after 2-4 days. Abamectin has a slow lethal effect because it does not cause rapid dehydration of insects. Although abamectin has direct contact killing effect on predatory in...
