Description

technical field

[0001] The invention relates to the field of plant protection, in particular to an endogenous biocontrol bacterial strain, in particular to a bacillus licheniformis 202 for efficiently preventing and controlling banana wilt and its application. Background technique

[0002] Banana Fusarium wilt is a devastating disease caused by the infection of Fusarium oxysporum f.sp.cubense, and it is a devastating soil-borne disease of banana production. The pathogen invades from the injured rhizome, spreads to the pseudostem and leaves through the vascular bundle, and blocks the xylem vessel until the plant withers and dies. Fusarium wilt of banana is a soil-inhabiting fungus, and its chlamydospores can survive in the soil for 8 to 10 years. Banana Fusarium wilt is distributed in many counties and cities in the banana production area of ​​the Pearl River Delta, and it has developed rapidly in recent years. The rate of diseased plants in the diseased garden is generally...
