Microbial medicine for preventing and controlling liberobacter asiaticum, and preparation method of microbial medicine

Abstract

The invention relates to the technical field of microbial medicines, in particular to a microbial medicine for preventing and controlling liberobacter asiaticum, and a preparation method of the microbial medicine. The microbial medicine for preventing and controlling the liberobacter asiaticum is mainly prepared from the following raw materials in parts by weight: 3-8 parts of liquorice root, 5-15parts of radix et rhizoma rhei, 2-5 parts of fructus xanthii, 2-8 parts of radix sophorae flavescentis, 3-8 parts of stem and leaf of Hongkong pavetta, 2-5 parts of radix euryae chinensis, 10-15 parts of cortex magnoliae officinalis, 2-6 parts of fructus quisqualis, 6-8 parts of rhizoma amorphophalli, 1-2 parts of poria cocos, 3-8 parts of rhizoma coptidis, 1-2 parts of bacillus subtillis and 0.5-1 part of trichoderma. All the components of the microbial medicine have a synergistic effect while giving full play to the respective functions, thus achieving the effect of effectively preventing and controlling the liberobacter asiaticum; furthermore, all the components are non-toxic and free from pollution, and do not cause residue of hazardous substances after being used; after the microbialmedicine is used, green, safe and harmless citrus can be obtained and are good for the health of people.

Description

technical field [0001] The invention relates to the technical field of microbial medicines, in particular to a microbial medicine for preventing and treating citrus huanglongbing and a preparation method thereof. Background technique [0002] Citrus huanglongbing is caused by a Gram-negative bacterium limited to the phloem, which can infect a variety of Rutaceae plants including citrus, aurantium, kumquat and murella. [0003] Citrus huanglongbing, also known as yellow shoot disease, yellow wilt, and green fruit disease, is distributed in more than 40 countries and regions around the world. Due to its serious damage and high fatality rate, it is called the "cancer" of citrus. Typical symptoms are mottled and yellowed leaves, defoliation, fruit drop, sharp drop in yield, smaller deformity of diseased fruit, soft and dull peel, sour taste, and reduced fruit quality, which seriously affect the yield and quality of citrus, and even cause garden damage. . [0004] At present, t...

AI Technical Summary

Problems solved by technology

[0004] At present, the prevention and control of citrus Huanglongbing is mainly chemical control. Citrus is an important source of fruit and juice. Whether it is insecticides against citrus psyllids or antibiotics and fungicides against Huanglongbing bacteria itself, although they have certain effects, they have never been used. Considering long-term human health and environmental safety, it is not suitable for large-scale promotion and application
