Traditional Chinese medicine for controlling tobacco bacterial wilt and preparation method of traditional Chinese medicine

Abstract

The invention discloses a traditional Chinese medicine for controlling tobacco bacterial wilt. The traditional Chinese medicine is prepared by the following Ingredients: sweet wormwood, astragalus, tripterygium wilfordii, buttercup, wrinkled gianthyssop, honeysuckle and panax pseudoginseng; all the Ingredients as above are ground by using a grinder, wherein a grinding sieve is 100-200 meshes and the temperature in grinding processing is controlled to 40-50 DEG C; and the ground ingredients are fully mixed to be uniform according to the weight ratio and then filled in bags and kept in a dark place for 24h, wherein the proportions by weight of the ingredients are as follows: 25-35 parts of sweet wormwood, 15-20 parts of astragalus, 10-15 parts of tripterygium wilfordii, 20-30 parts of buttercup, 15-20 parts of wrinkled gianthyssop herb, 25-35 parts of honeysuckle and 30-40 parts of panax pseudoginseng. Through coordination matching of all ingredients in the traditional Chinese medicine, a rhizosphere micro-ecological environment can be regulated, the growth of bacterial wilt bacteria is restrained and the natural immunity of tobacco plants is improved. The traditional Chinese medicine has the characteristics of being safe to nontarget organism and the like, has strong selectivity so that pests can not easily generate resistance to medicament; and therefore, the traditional Chinese medicine is a novel environment-friendly bactericide excellent in compatibility with environment.

Description

technical field [0001] The invention relates to the technical field of tobacco disease prevention and control, in particular to a traditional Chinese medicine for preventing and treating tobacco bacterial wilt and a preparation method thereof. Background technique [0002] Ralstonia solanacearum is a devastating soil-borne disease caused by Ralstia solanacearum. Ralstia solanacearum survives for a long time and spreads quickly, especially the bacterial rhizome disease of Solanaceae crops that avoid continuous cropping such as tobacco Bacterial wilt brings the greatest loss to agricultural production. At present, no effective chemical control method has been found, and the chemical agents pollute the environment, destroy the soil balance, and have poor curative effect. At present, the production of organic tobacco leaves is generally carried out in major tobacco areas across the country, and microbial agents are generally used for organic biological control, but the control ...

Problems solved by technology

At present, no effective chemical control method has been found, and the chemical agents pollute the environment, destroy the soil balance, and have poor curative effect

At present, the production of organic tobacco leaves is generally carried out in major tobacco areas across the country, and microbial agents are generally used for organic biological control, but the control effect is poor, the control object is single, and the cost is high; compared with the above two fungicides, traditional Chinese medicine fungicides have Natural, low-toxic or non-toxic, and non-residual, but currently there are few reports on pure botanical agents for tobacco bacterial wilt, especially those that can be used on organic tobacco leaves, and the curative effect is difficult to guarantee
