Abstract

The invention belongs to the technical field of pesticide compounding, and specifically relates to a wettable powder containing flucyvalerate and its application. The active ingredients of the composition are liuyangmycin and flucyvalerate, wherein the weight ratio of liuyangmycin to flucyvalerate is: liuyangmycin:flucyvalerate=1:1-15, reducing pesticides The amount of use improves the control effect, alleviates the current problem of pest resistance to the greatest extent, achieves the purpose of protecting crops, and can improve yield and quality.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, and specifically relates to a wettable powder containing flucyvalerate 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 active ingredient. The pure product i...
