Abstract

The invention discloses a method for preventing and treating diseases and pests through ginkgo biloba sarcotesta. The method comprises the steps of I, firstly, preparing ginkgo biloba sarcotesta, then, weighing and cleaning ginkgo biloba sarcotesta; and II, dividing ginkgo biloba sarcotesta extracts EGBE-1 and EGBE-2 into three parts, freeze-drying the first part, storing the freeze-dried first part in a refrigerator with the temperature of minus 20 DEG C, detecting effective metabolic components, measuring the content and activity of phenylalnine ammonialyase, naturally drying the second part, storing the naturally dried second part at the room temperature, carrying out response surface method design treatment, accurately weighing a sample, repeating the steps three times, preparing crude extracts through organic solvent extraction and aqueous solution extraction, concentrating the crude extracts into an extract, carrying out column adsorption purification concentration and drying to obtain gingko flavonoid substances, terpenoids lactone substances, phenolic acid substances, polysaccharose substances, steroid substances, ketosteroid substances and other compounds for pest control, and after carrying out digestion on the third part through an aqueous solution, ethyl alcohol and an acetone organic solution, filtering and diluting the digested third part for preventing and treating diseases and pests.

Description

technical field [0001] The invention relates to a method for preventing and controlling diseases and insect pests by exocarp of ginkgo biloba. Background technique [0002] Adopt pesticide to carry out insect pest control to ginkgo leaf in prior art at present, but current pesticide has very big damage to ginkgo leaf, and also can pollute environment. Contents of the invention [0003] The invention provides a method for preventing and controlling diseases and insect pests by the outer testa of ginkgo biloba, which can significantly prevent and control various diseases and insect pests in field. [0004] The present invention has adopted following technical scheme: a kind of method of ginkgo testa preventing and treating diseases and insect pests, it is characterized in that it comprises the following steps Step 1, first prepares ginkgo testa, then weighs, cleans ginkgo testa; [0005] Step 2, then prepare Ginkgo biloba extracts EGBE-1 and EGBE-2, then divide the Ginkgo b...
