Problems solved by technology

Rice smut not only reduces the yield of rice, but also affects the quality of rice. Eating contaminated rice will affect the health of humans and animals
There is no specific chemical agent for the control of rice false smut, and the use of common chemical agents for the control of rice false smut is not effective, which will not only cause environmental pollution, but also cause food safety problems

[0027] Inhibitory effect of 6-pentyl-2H-pyran-2-one compound on Fusariumoxysporum f.sp.cubense race 4 and Ustilagi noideavirens

[0028] 1. Bacterial solution preparation: Prepare 100mL of PDB medium and put it in a 500mL Erlenmeyer shake flask, pick it from the previously activated PDA plate with Fusarium oxysporum f.sp.cubense race 4 and Ustilaginoideavirens pathogenic bacteria Small bacterial blocks were respectively placed in PDB medium, placed in a shaker at 120r / min, and cultured at 28°C for 24h. Then take a small amount of cultured bacterial solution and dilute it to 1×10 with sterile PDB medium. 8 Spores / ml (hemocytometer count).

[0029] 2. Sample solution preparation: the 6-pentyl-2H-pyran-2-one monomer compound to be tested was prepared into a solution with a concentration of 15 mg / mL in methanol for use.

[0030] 3. Specific operation: Take 10 μL of the diluted pathogen spore solution, drop them on the sterilized filter paper sheets of about 1 cm in size, and aft...

Abstract

The invention discloses an application of a 6-amyl-2H-pyran-2-ketone compound in preparing microbial agent for resisting fusarium oxysporum f.sp.cubense 4 physiological race and ustilaginoidea virens.The application has the technical effects as follows: the 6-amyl-2H-pyran-2-ketone compound has a remarkable inhibition function on growth of fusarium oxysporum f.sp.cubense 4 physiological race andustilaginoidea virens and has a good control function on banana wilt and rice false smut. The 6-amyl-2H-pyran-2-ketone compound is an efficient and non-toxic natural product, and that is, an efficientand non-toxic natural pesticide is provided for control of the banana wilt and the rice false smut.

Description

technical field [0001] The invention relates to the technical field of natural medicines, in particular to the application of 6-pentyl-2H-pyran-2-one compound in the preparation of pathogenic bacterial agents against banana wilt and rice false smut. Background technique [0002] my country's banana planting areas are mainly concentrated in Guangdong, Guangxi, Hainan, Yunnan and Fujian provinces. my country is the largest producer of bananas in the world, as well as the largest consumer of bananas. In the international trade of bananas in the world, my country maintains the status of a net importer and imports a large number of bananas every year. Therefore, strengthening banana production plays an important role in my country's social and economic development. The biggest limiting factor in banana production is the prevention and control of banana fusarium wilt. Fusarium wilt is a devastating hazard to banana production and often leads to the destruction of banana farmers. ...
