This folio touch disease induce the establishment of non-white spot , which gradually enlarge and emerge until the feign leafage turns brown or yellow . This disease drastically reduce a banana tree ’s fruit production . Removing the affected foliage and pruning foliage for better melodic line circulation can reduce the risk of shameful Sigatoka infections .
Panama Disease
Panama disease of banana tree is a classical vascular wilt disease due to a fungus ( Fusarium oxysporum ) . The fungal pathogens get in the banana tree diagram through the xylem , and then employ the water stream to spread the fungal spores throughout the entire plant . These spores lodge into the vessel walls and barricade the water catamenia , causing banana leaf to wilt and buy the farm . Panama disease often kills intact banana tree trees . The fungous pathogens can pull round in the soil for almost 20 years . This disease is extremely difficult to control , and almost ruin Central America ’s banana production back in the 1940s and 1950s .
Banana Bract Mosaic Virus

Red or unripe run or lesions sometimes appear on the unexampled leaves , while greensick streak often form on the cluster stanch . Banana bract mosaic virus can cause meaning fruit loss on move Tree . This banana works disease is unmanageable to assure because the symptom are frequently inconspicuous . Preventative bar include using virus - liberal livestock and planting materials .
Banana Bunchy Top Virus
