Bromfenitrile, the English name is Chlorfenapyr, the trade name is Dejin suspension agent, and the Chinese common name is Bufenitrile. It is a new heterocyclic insecticide, acaricide and nematicide developed by the American cyanamide company. With the introduction of the national high toxicity pesticide substitution policy and the improvement of people's environmental protection awareness, as the representative of the recommended pesticide varieties for pest control of pollution-free agricultural products, the application of low toxicity and high efficiency bromfenitrile is becoming more and more widespread.
Action mechanism
Bromfenitrile is a precursor of insecticide, which has no toxicity to insects. After insects feed on or contact bromfenitrile, bromfenitrile is converted into specific insecticidal active compounds under the action of multifunctional oxidase in insects, and its target is mitochondria in insect body cells. It causes the cell synthesis to stop its life function due to lack of energy. After the injection, the pest activity becomes weak, spots appear, color changes, activity stops, coma, paralysis, and finally death.
Product use
Pyrrole insecticides and acaricides with new structure. It has excellent control effect on boring, sucking and chewing pests and mites. It is more effective than cypermethrin and cypermethrin, and its acaricidal activity is stronger than dicofol and tricyclic tin. The agent has the following characteristics: broad-spectrum insecticide and acaricide; It has both gastric toxicity and touch killing effects; No cross resistance with other insecticides; It has moderate residual activity on crops; In the nutrient solution, it has selective internal absorption activity through root absorption; It has moderate oral toxicity to mammals and low dermal toxicity; The effective dosage is low (100g active ingredient/hm2). Its remarkable insecticidal and acaricidal activities and unique chemical structure have attracted extensive attention and attention.
