What should I do with Panama disease.. control measures of it ? How can I stop it further ? Would it be effect in the harvesting ,?

Hi! check out the detailed description on Panama Disease there you can also find advices how to proceed. In general there is no curative way to control this disease. What is important that you prevent the fungus from spreading! Also you could plant resistant cultivars on the plots which are infested, so you can continue to grow Bananas over there.
