Abstract

The invention belongs to the technical field of the compounding of farm chemical pesticides, and in particular relates to water dispersible granules containing amitraz and an application. Active ingredients of the composition are iuyangmycin and amitraz, and the weight ratio of the iuyangmycin to amitraz is 10: 1 to 1:1, a good synergistic effect can be realized by virtue of compounding, the environmental protection trend of the society in the future can be satisfied, the effective and active control spectrum can be enlarged, and the water dispersible granules have characteristics of high speed, long lasting period, low consumption and environment friendliness.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, in particular to a water-dispersible granule containing amitraz 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 p...
