Abstract

The invention belongs to the technical field of combination of pesticides, and concretely relates to a wettable pulvis containing beta-cypermethrin and application. The effective components of the composition comprise hiuyangmycin and beta-cypermethrin with the weight ratio of 1-15:1, the usage amount of pesticides is reduced, the control effect is improved, the current insect drug-resistance problem is furthest alleviated, the purpose of protecting crops is realized, and the yield and the quality are improved.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, in particular to a wettable powder containing beta-cypermethrin 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 is a co...
