After the diseased plant was dried up, it was excavated and burned to prevent spread to surrounding plants; The banana plantation with a disease rate of more than 30% can be used for water and drought rotation. After 1-2 years of rice replanting, the varieties resistant to Fusarium wilt can be replanted, such as Nongke No.1, Anti-Huang No.5, Baodaojiao. Etc.; in the banana orchard with an incidence of more than 50%, it is not appropriate to plant bananas and replant other crops.
