Abstract

The invention provides a novel use of ginkgolide C. Ginkgolide C is a novel and environmentally friendly pesticide having no damage on people and livestock, and has profound meanings to long-term ecological development, human health and mite pest comprehensive control. Compared with a traditional pesticide, in mite pest control, ginkgolide C has the advantages that 1, ginkgolide C is extracted from natural ginkgo leaves, is easy to decompose under the natural conditions, has no damage on the environment and the surrounding ecological system and no pollution on the environment, and is rich in development and application values; 2, ginkgolide C is easy for artificial synthesis and is beneficial for industrialized production; and 3, ginkgolide C can be compounded with other mite pest control active ingredients in preparation-type plants to form a pesticide so that mite pest control effects are further improved.

Description

technical field [0001] The invention relates to a new application of ginkgolide C, in particular to a new application of ginkgolide C in preparing acaricides. Background technique [0002] Ginkgolide C, Chinese alias: ginkgolide C, English name: Ginkgolide C, molecular formula: C 20 h 24 o 11 , white crystals (precipitated in methanol), belonging to diterpenoids, highly polar, soluble in hot water; Ginkgolide C is mainly derived from Ginkgo biloba leaf extract, which has a good effect on the treatment of cardiovascular and cerebrovascular diseases auxiliary role. Tetranychus cinnabarinus is a herbivorous mite with the characteristics of small size, rapid reproduction, short development period, small range of action, strong adaptability, high mutation rate and easy occurrence of drug resistance. It is recognized as the most difficult pest community to control. With the enhancement of human awareness of environmental protection, people's research on new acaricides is also ...
