Botanical pesticide for wilt control

Abstract

The invention discloses a botanical pesticide for wilt control. The preparation method of the botanical pesticide includes: mixing 1-2% by volume of trehalose, 0.1-0.6% by volume of chitosan and the balance Chinese medicinal components uniformly to obtain an active mixed medium containing traditional Chinese medicines; inoculating a compound microbial strain into the active mixed medium containingtraditional Chinese medicines for fermentation culture until the microbial concentration reaches 4 billion plants/ml, thus obtaining the botanical pesticide for wilt control. The Chinese medicinal components include: sophora flavescens, sweet wormwood herb, elephantopus tomentosus, honeysuckle, andrographis paniculata, cortex dictamni and fructus kochiae. The botanical pesticide provided by the invention can achieve effective control of wilt without pollution.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a botanical pesticide for preventing and treating Fusarium wilt. Background technique [0002] Fusarium wilt is the main disease of solanaceous vegetables such as tomato, eggplant, pepper and potato. The main symptom is that the plants wilt and die quickly, and the stems and leaves remain green. The browning part of the diseased stem is squeezed by hand, and milky white bacteria liquid is discharged. For a long time, chemical pesticides have been used to control Fusarium wilt. [0003] In recent years, the pollution of pesticides has gradually attracted great attention from all over the world, and low-toxicity and low-residue pesticides have become the focus of research. Biopesticides can directly use natural biological substances and the interaction between organisms to control pests and weeds or improve ecology, so biopesticides are internationally recognized as the most promising ...
