Plant-derived pesticide for controlling bacterial wilt

Abstract

The invention discloses a plant-derived pesticide for controlling bacterial wilt. The plant-derived pesticide for controlling bacterial wilt is prepared according to the following steps: uniformly mixing 1 to 2% by volume of trehalose, 0.1 to 0.6% by volume of chitosan and the balance of traditional Chinese medicine components to prepare a traditional Chinese medicine-containing active mixed medium; and inoculating a composite microbial strain into the traditional Chinese medicine-containing active mixed medium for fermentation culture until the concentration of microorganisms reaches 4.0 billion plants / mL, so as to obtain the plant-derived pesticide for controlling bacterial wilt. The traditional Chinese medicine components comprise radix sophorae flavescentis, herba artemisiae annuae, elephantopus tomentosa, flos lonicerae, coptidis rhizoma, cortex dictamni and fructus kochiae. The plant-derived pesticide can effectively prevent and treat bacterial wilt disease without 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...
