Problems solved by technology

[0004] Due to the fact that chemical agents are very easy to cause phytotoxicity, they are easily washed away by rainwater and become invalid when they are applied, and there is a lack of high-efficiency and low-toxic chemical control drugs. Continuous use of drugs will easily cause pesticide residues, which will have a bad impact on the environment, pollute water sources, and cause human and animal poisoning. death, and at the same time cause pathogenic bacteria to develop drug resistance, resulting in certain restrictions on its use
On the other hand, tobacco wildfire disease and red spot disease are tobacco mature diseases. As the requirements for safety are getting higher and higher, higher requirements are raised for tobacco cultivation itself, especially for tobacco wildfire disease and red star disease. It is not suitable to use residual chemical agents for the control of this mature disease

Abstract

The invention discloses a microbial inoculant for preventing both tobacco brown spot disease and wild fire disease and a preparation method thereof, belonging to the technical field of green prevention and control. The microbial inoculum of the present invention comprises Achromobacter 12%-25%; Enterobacter 6%-13%; Paleobacillus hominis 5%-15%; Stenotrophomonas 46%-58%; Bacillus subtilis 8%-13% 12%. The preparation method has the following steps: preparing Achromobacter, Enterobacter, Paleobacter hominis, Stenotrophomonas, and Bacillus subtilis into a compound microbial inoculum in a volume ratio, the application method is spray application, and the front and back sides of the leaves are applied. apply. Tests have proved that the microbial inoculum prepared by the invention has a strong inhibitory effect on the pathogenic bacteria of tobacco scab and wild fire, shows good disease prevention effect on tobacco scab and tobacco wild fire, and has low cost, good effect, It is environmentally friendly, so it has a good prospect for the development of biological pesticides.

Description

technical field [0001] The invention belongs to the field of green prevention and control, and in particular relates to a microbial inoculant that also prevents tobacco wildfire and scab disease and a preparation method thereof. Background technique [0002] Tobacco is an important economic crop, and the tobacco industry is an important pillar industry in my country. Hunan Province is an important tobacco production and planting area in China. In recent years, the area of ​​tobacco planting has expanded year by year, and the incidence of tobacco diseases has also increased. Tobacco wildfire disease and red star disease are bacterial diseases and fungal diseases, respectively. These two diseases have occurred in Hunan, Shandong, Heilongjiang, Yunnan and other places year after year, causing serious harm and rising trend in recent years. [0003] Tobacco wildfire and scab have high incidence and wide incidence area, and seriously affect the yield and quality of flue-cured tob...
