Embodiment 1

[0040] Embodiment 1: Preparation of Tiezi glabra extract 1

[0041] Take 2.0kg of the root of Tiezi glabra, air-dry it naturally, crush it, extract it twice with 10L of methanol at room temperature, each time for 48 hours, and concentrate under reduced pressure to obtain 300g of Tiezi glabra root extract, which is the Tieza glabra extract 1.

Embodiment 2

[0042] Embodiment 2: Preparation of Tiezi glabra extract 1

[0043] Take 2.0kg of the stem of Tieza glabra, dry it naturally, crush it, extract it twice with 10L of methanol at room temperature, 48 hours each time, and concentrate under reduced pressure to obtain 250g of the stem extract of Tieza glabra, that is, the extract of Tieza glabra. Object 1.

Abstract

The invention relates to the technical field of phytoextraction and particularly discloses a myrsine stolonifera extractive, a method for preparing the myrsine stolonifera extractive and application of the myrsine stolonifera extractive. From the perspectives of greening, environmental protection, safety and high efficiency, myrsine stolonifera of plants is used as a raw material of biological pesticide, and the myrsine stolonifera extractive is prepared and extracted through the methyl alcohol chromatography, the resin chromatography and the silica gel chromatography. The myrsine stolonifera extractive has obvious biological inhibitory activities for pests such as houseflies, bipolaris maydism and phyricularia grisea and can be applied to preparation of pesticide preparations.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to an extract of A. glabrata and its preparation method and application. Background technique [0002] Housefly is the main disturbing insect and environmental sanitation pest in the city. If it is not prevented and controlled in time, it will have a great impact on people's living environment; corn gray spot, corn small spot, corn sheath blight, and rice blast , Common diseases of rice, effective control will reduce the loss of crops. [0003] At present, the control of housefly and these diseases still depends on pyrethroids and chemical fungicides. However, the environment and food safety have attracted more and more people's attention, and the problems of excessive pesticide residues, environmental pollution and resistance caused by pesticides have become the focus of social attention. Therefore, the development of high-efficiency, low-toxicity, low-residue, low-carbo...
