Synopsis (short abstract) This poster is designed to provide banana exporters with a graphical overview of how farms can be protected against Tropical race 4 (TR4) and its spread given the complexity of the fruit’s journey from farm to final destination. It highlights the need for exporters to follow all security recommendations from their local authorities with infographic-style instructions. This is one of four posters in a series on TR4 and its prevention.

    The purpose of the infographic What is Tropical Race 4 (TR4)? is to inform the general public on the nature of the Tropical race 4 (TR4) with some key facts on its origins and how it spreads. One fact that is emphasized is that TR4 is not harmful to humans and does not affect the fruit itself. Support is needed for disease management and recovery in affected countries as well as for international collaboration and national actions. This is one of a pair of two infographics on TR4 and its prevention.

    What you need to know about Tropical Race 4

    The flyer, What you need to know about TR4, aims to inform the general public with basic information about Tropical race 4 (TR4). The underlying message is that actions can indeed be taken to help prevent the spread of the pest and that the way forward is for stakeholders across the banana industry to act with urgency and in a collaborative manner. Fusarium Tropical race 4 (TR4) is a strain of the soil born fungus, Fusarium oxysporum f. sp cubense whose spores can lie dormant in the soil until a susceptible plant is established nearby. These spores infect the plant through the roots and inhabit the banana or plantain plant’s xylem vessels, blocking the flow of water and nutrients. Fungicides can't save plants that are already infected with TR4, and the fungus's spores persist in soil for decades. Therefore the most immediate approach to combat TR4 is prevention of its spread into clean areas and containment when it is detected. In the long term, diversification of crops and better use of available genetic resources are key to building resilience to the disease. Agro-ecological innovations will be increasingly important to produce varieties less susceptible to TR4. The flyer focuses on three practical items that a visitor to a banana or plantation farm can do to minimise the risk of spreading TR4.

    Prevention and diagnostic of Fusarium Wilt (Panama disease) of banana caused by Fusarium oxysporum f. sp. cubense Tropical Race 4 (TR4). Technical Manual 2014

    Global banana production is seriously threatened by the re-emergence of a Fusarium Wilt. The disease, caused by the soil-borne fungi Fusarium oxysporum f. sp. cubense (Foc) and also known as “Panama disease”, wiped out the Gros Michel banana industry in Central America and the Caribbean, in the mid-twentieth century. The effects of Foc Race 1 were overcome by a shift to resistant Cavendish cultivars, which are currently the source of 99% of banana exports.
