The much-feared Tropical Race 4 strain of the Fusarium oxysporum soil fungus which causes Panama disease in Cavendish bananas has now been discovered in Myanmar. This follows closely on the heels of its discovery in Vietnam and Laos. The fungus is expected to have disastrous consequences on individual banana growers and the global banana industry. Scientists from Wageningen University & Research working with colleagues abroad have detected the fungus and used advanced techniques to find out where it came from.
