Banana yellow leaf disease is very difficult to cure, to face yellow leaf disease, there are only two ways is prevention and control. Non-outbreak areas are heavily protected against infection, and areas with outbreaks seek to reduce harm and prevent the spread of the outbreak.

Banana farmers are encouraged to establish isolation zones on farms to prevent pathogens from moving between planting materials and contaminated soil and water. In order to prevent TR4 from spreading with people and vehicles, a washing and disinfection area for people and vehicles has also been set up around the banana garden. 800 times of Bacillus subtilis WP aqueous solution was drenched on the root every 15~20 days, and 500 times of 50% carbendazim WP aqueous solution was injected on the stem every 15~20 days, which could obviously reduce the incidence of disease.

The solution for the infected areas to coexist with the pathogen and continue to produce bananas is to replant varieties resistant to TR4. In addition, rotation with banana non-host plants is also considered an effective way to reduce the incidence of yellow leaf disease. At present, some countries adopt rotation of sugarcane, rice, cassava and banana, while Chinese research points out that rotation of leek and banana effectively reduces the incidence of TR4.

When the stem of the banana with yellow leaf disease was cut longitudinally, it was found that the vascular bundle of the diseased plant was yellow to brown, which was different from that of the normal healthy banana.

A large amount of decomposed miscellaneous organic fertilizer (1,500~2,000 kg/plot) was mixed with soil thoroughly before planting, and the soil was kept moist. Banana seedlings were planted after 7~10 days of cultivation of soil beneficial microorganisms. Many organizations are also actively conducting yellow leaf disease workshops to build awareness of TR4 among banana workers.

Very cool article!
