Biological pesticide specially used for eggplants, and preparation method of biological pesticide

Abstract

The invention discloses a biological pesticide specially used for eggplants, and a preparation method of the biological pesticide, belonging to the technical field of crop pesticide preparation. The biological pesticide is mainly prepared from the following raw materials: radix sophorae flavescentis, cortex dictamni, broadleaf holly leaf, Chinese honeylocust spine, honeysuckle flower, herba menthae, folium eriobotryae, radix rehmanniae, folium artemisiae argyi, common nandina leaf, liquorice root, purslane herb, rhizoma menispermi and herba speranskiae tuberculatae. The biological pesticide contains multiple substances such as kushenin, dictamnine and polyphenols, thus not only having an inhibiting effect for multiple pathogenic bacteria, but also being capable of controlling pests such as aphids, Chinese chive maggots and red spiders and having a good promotion effect for all growth processes of the eggplants. Chemicals are not added into the biological pesticide specially used for the eggplants, so that the biological pesticide is safe and reliable in quality and environment-friendly; the biological pesticide is good in control effect for plant diseases and insect pests of the eggplants, simple and reasonable in preparation method, low in comprehensive cost, simple and flexible in use method and easy to popularize and apply.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of crop biopesticide preparation, in particular to a special biopesticide for eggplant and a preparation method thereof. [0003] 【Background technique】 [0004] Eggplant is a plant of the family Solanaceae, which is native to tropical Asia and is cultivated in all provinces of the country. It is one of the common edible vegetables. Eggplant is rich in nutrients and contains protein, fat, carbohydrates, vitamins, calcium, phosphorus, iron and other nutrients, which can enhance the adhesion between human cells, prevent microvascular rupture and bleeding, maintain normal cardiovascular function, and prevent bad blood. diseases, and promote wound healing. At the same time, it contains trace elements such as phosphorus, calcium, and potassium, and various alkaloids such as choline, trigonelline, stachydrine, and solanine. Especially, the vitamin content in purple eggplant is higher, which can inhibit th...

Problems solved by technology

These diseases and insect pests are harmful to a certain extent during the seedling stage, adult plant stage, fruiting stage and storage period of eggplant. If they are not treated and treated in time, the growth of eggplant will often shrink, or directly lead to production reduction or stoppage, causing serious damage. Economic losses

[0006] The invention with the publication number CN104082074A discloses "a method for preventing and controlling eggplant diseases and insect pests". Various chemical agents such as formalin solution, Bordeaux mixture, and carbendazim are used to treat eggplant brown spot, cotton blight, verticillium wilt, tea Although the prevention and control effect of yellow mites and red spiders is good, the chemical pesticides commonly used are toxic to a certain extent, and there will be certain residues in the process of using crops, which poses a potential threat to human health.

[0007] The invention with the publication number CN103651607B discloses "a biopesticide for vegetables and its preparation method". Preparation of biological pesticides for vegetables, which is characterized by the use of toyocamycin compounded with traditional Chinese medicine extracts, which can expand the spectrum of sterilization and insecticide, and can also improve drug efficacy, but toyocamycin is a nuclear antibiotic produced by Streptomyces, It has a certain degree of toxicity, and long-term use can easily lead to drug resistance in crops, and is easily restricted and interfered by environmental factors, and the control effect is unstable

Although the 7 kinds of Chinese herbal medicinal materials used in the present invention have remarkable antibacterial effects, their control effects on pests such as aphids and red spiders are not obvious
