“TR4, is a strain of Fusarium oxysporum f.sp. cubense (Foc) fungus. Foc has been known to cause Panama disease in bananas since the early 20th century, and has caused major yield loss in bananas, an important staple food in many countries. The spread of TR4 is of major concern as it affects the Cavendish variety of banana, a variety which accounts for 47% of global production, and is the main variety grown for export.”
At the end of 2019, a new species portal was added to CABI’s Invasive Species Compendium (ISC) to bring together information and data related to Fusarium oxysporum f.sp. cubense tropical race 4. This portal, which is Open Access and available to all, brings together data on the current distribution, the latest research on the problem, and provides links to practical identification and management information.
