preparation example Construction

[0064] The embodiment of this group provides a preparation method of biological control agent. All the examples in this group have the following common features: the preparation method of the biological control agent includes: using bamboo leaf Fangfeng essential oil as the active ingredient of the biological control agent.

[0065] In some embodiments, the essential oil of bamboo leaves and wind is extracted from the rhizome of bamboo leaves and wind;

[0066] Preferably, extracting the rhizome part of bamboo leaves and windproof by steam distillation;

[0067] Preferably, the extraction temperature of the steam distillation method is 90-110°C, preferably 100°C; the extraction time is 3-8h, preferably 6h;

[0068] Preferably, the extractant is n-hexane, and the extraction time is 1-4h, preferably 2h;

[0069] Preferably, the extracted n-hexane layer is dried and concentrated; preferably, the drying refers to removing the moisture of the n-hexane layer with anhydrous sodium ...

experiment example

[0086] Experimental example, preparation and verification of insecticidal effect of bamboo leaf windproof essential oil of the present invention

[0087] 1. Plant essential oil preparation

[0088] Take the rhizome part of bamboo leaves and wind, dry it naturally in the shade, crush it, put it in a volatile oil extractor after weighing, and extract it by steam distillation. The extraction time is generally 6 hours. Extract it with n-hexane to obtain the n-hexane layer, add anhydrous sulfuric acid Remove water from sodium, concentrate, measure the volume, put the volatile oil into a dry glass bottle, and store it in a refrigerator at 4°C.

[0089] 2. GC-MS test

[0090] The volatile oil samples were analyzed by GC-MS. The test conditions were: GCMS-QP2010 plus (Shimadzu); Chromatographic column: DB-5MS (60m×0.25um×0.32mm) (Agilent); Heating rate: 60°C-10 ℃ / min-300℃-20min; split ratio: 30:1; constant linear velocity mode: 30cm / sec; carrier gas: He; ion source temperature: 200℃...

Abstract

The invention relates to application of Seselimairei Wolff in biological prevention and control, a biological prevention and control medicament and a preparation method of the medicament, and belongs to the field of biological prevention and control. The invention provides the application of Seselimairei Wolff in the field of biological prevention and control, and further provides the biological prevention and control medicament based on the application. The biological prevention and control medicament comprises active ingredients, and the active component comprises Seselimairei Wolff essential oil. By utilizing the new application of the Seselimairei Wolff or adopting the insecticide / insecticidal method disclosed by the invention, the Frankliniella occidentalis, cotton aphid or phylloxera can be efficiently killed; and the Seselimairei Wolff is a wild plant, is wide in distribution range, is simple and easy to obtain, is low in cost and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the field of biological control, and in particular relates to the application of bamboo leaf fangfeng in biological control and its biological control agent and preparation method. Background technique [0002] Bamboo Leaf Fangfeng, from "Southern Yunnan Materia Medica", aliases: Jizufangfeng, Yunfangfeng, Xifangfeng. For the root of Umbelliferae parsnip Seselimairei Wolff. Perennial herb, 30-50 cm high. There are oblong taproots. It can be excavated in spring and autumn, washed and dried in the sun. Function cures mainly: relieve exterior syndrome, dispel wind, win dampness. Control common cold, anemofrigid-damp arthralgia, carbuncle sore, tetanus. [0003] Psyllids are an important group of insects in the order Homoptera. It is also the general term for the family Psyllididae of the order Homoptera. For gradual metamorphosis insects, individual development goes through three stages: egg, nymph and adult. Mouthparts pi...
