Abstract

The invention discloses a botanical pesticide for controlling ralstonia solanacearum. 1-2% by volume of trehalose, 0.2-0.5% by volume of chitosan and the balance traditional Chinese medicine components are evenly mixed to produce an active mixed culture medium containing traditional Chinese medicines; the active mixed culture medium containing the traditional Chinese medicines is inoculated against a compound microbial strain for fermentation culture until the concentration of microorganisms reaches 3.5 billion/ml, so that the botanical pesticide for controlling ralstonia solanacearum is obtained; and the traditional Chinese medicine components comprise radix sophorae flavescentis, herba abrotani, elephantopus tomentosus, flos lonicerae, herba andrographitis, dittany bark and fructus kochiae. The botanical pesticide can effectively control ralstonia solanacearum without causing pollution.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a botanical pesticide for preventing and treating bacterial wilt. Background technique [0002] Bacterial wilt is the main disease of tomato, eggplant, pepper, potato and other solanaceous vegetables. 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 bacterial 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 promisin...
