2021 Panama TR4 Epidemiological Review

Abstract

The global spread of Fusarium wilt tropical race 4 (TR4) has been rapid with explosive epidemics developing in many overseas Cavendish plantations. An incursion of TR4 was identified in the Tully Valley in March 2015, with new incursions being subsequently detected on four additional properties. Losses have been minimal due to early detection and destruction of diseased plants before they release inoculum into the soil, and acceptance of biosecurity preparedness by the industry. The world banana community is using Queensland as a case study on how to handle an incursion of TR4. This is a highly positive result and justifies past investment in surveillance, eradication, and containment activities.
