Abstract

The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to a water-dispersible granule of liuyangmycin and diflunron and its application. The active ingredients of the composition are liuyangmycin and dichranuron, wherein the weight ratio of liuyangmycin and dichranuron is: liuyangmycin: difluranuron=1:1‑1:15, and the compounding effect is very good. The synergistic effect reduces the amount of pesticides used, and also alleviates the impact on the environment. More importantly, the compound combination effectively resists the problem of pest resistance, and alleviates the current problem of pest resistance to the greatest extent. The problem is in line with the trend of green environmental protection in the future society.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to a water-dispersible granule of liuyangmycin and diflunron and its application. Background technique [0002] Liuyangmycin [0003] 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 of various crops, has no systemic property, and the agent is lipophilic. Both spider mites and gall mites are effective. Compounded with some organophosphorus or carbamate pesticides, it has a significant synergistic effect. The contact effect on harmful mites lasts for 7 to 14 days. [0004] Physical and chemical properties: It is a mixture composed of 5 components, and tetrabactin is the main acti...
