Abstract

The invention discloses brassinolide soluble granules and a preparation method thereof. The brassinolide soluble granules consist of brassinolide, a cosolvent, a wetting agent and a soluble carrier, and are prepared by dissolving brassinolide, the cosolvent and the wetting agent in an organic solvent, coating the obtained mixed solution on the soluble carrier by spraying and finally removing the solvent.

Description

technical field [0001] The invention relates to a pesticide processing technology, in particular to a brassinolide soluble granule and a preparation method thereof. Background technique [0002] Brassinolide (BR for short), also known as brassinolide, was first isolated and discovered from rape pollen by Dr. Mirchell and others in the United States in 1970. biologically active substances. [0003] In 1979, American scientists extracted and identified the structure from 225kg rape pollen, and the results were published in the journal Nature. In the mid-1990s, Japanese scientists carried out research on the synthesis and agricultural application of BRs with persistent effects, see literature: Suguru Takatasuto et al. Twenty-third Annual Meeting of The Plant Growth Regulation Society of America, July14-18, 1996 . In the following ten years, scientists from all over the world have carried out research and promotion work on synthesis, plant physiology, biochemistry and agricul...
