Abstract

The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to the application of water-dispersible granules for controlling whitefly. The active ingredients of the composition are liuyangmycin and buprofezin, wherein the weight ratio of liuyangmycin to buprofezin is: liuyangmycin:buprofezin=5:1-20:1, 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, and specifically relates to a water-dispersible granule for controlling whitefly and its application. Background technique [0002] Buprofezin [0003] Solubility: 9mg / L in water (20°C), 520g / L in chloroform, 370g / L in benzene, 320g / L in toluene, 240g / L in acetone, 80g / L in ethanol, 20g / L in hexane ( both at 25°C). [0004] It is a chitin synthesis inhibitor of heterocyclic insects, which destroys the formation of new epidermis of insects, interferes with the normal growth and development of insects, and causes the death of insects. It has strong contact and stomach poisoning effects and is permeable. [0005] Liuyangmycin? [0006] 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...
