Abstract

The invention belongs to the technical field of compounding pesticides and insecticides, and in particular relates to the application of water-dispersible granules for preventing and treating white-backed planthopper. The active ingredients of the composition are liuyangmycin and heflubenzuron, wherein the weight ratio of liuyangmycin to hexaffluben is: liuyangmycin: hexaffluben=10:1-25:1, which plays a very good role in compounding. The synergistic effect reduces the amount of pesticides used, which is in line with the trend of green and environmental protection in the future society, and has the characteristics of low expansion and environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, in particular to a water-dispersible granule for preventing and treating white-backed planthopper and its application. Background technique [0002] Flufenuron [0003] Flubenzuron is a new type of phenylformyl urea insecticide. It has stomach poisoning and contact killing effects, and has no systemic effect. It is a low-toxicity insecticide. Safe for crops. The mechanism of action of hexafenzuron is mainly to inhibit the synthesis of chitin, and after the insect body contacts, it destroys the formation of chitin in insects. [0004] Liuyangmycin? [0005] It is an antibiotic with a macrocyclic lactone structure produced by Streptomyces griseus Liuyang varietal. It is a low-toxicity, low-residue, broad-spectrum acaricide that can prevent and control various mites in various crops, and has a good control effect. It has good contact killing effect on spider mites...
