ProjectStrengthening Capacities to Contain and Manage Fusarium Oxysporum F.Sp. Cubense Tropical Race 4 on Bananas in Lebanon - TCP/LEB/3803 2024

No results found.Banana Fusarium wilt disease, one of the most destructive diseases of banana, is caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense (Foc). In the 1950s, the epidemic caused by Race 1 of the pathogen wiped out the banana industry in Central America and the Caribbean. The effects of Foc Race 1 were overcome by a shift to resistant Cavendish cultivars, which are widely found in markets today and are the source of 99 percent of banana exports. Symptoms of Fusarium wilt appeared in bananas from the Cavendish group in 1967 in Taiwan and the strain was identified in 1994 as a new race, Tropical Race 4 (TR4). Subsequently, Foc TR4 spread throughout South-east Asia, reaching the Middle East in 2013 and being reported in 27 countries, where it caused serious economic losses. It was expected that, by 2028, the disease would lead to a loss of an estimated 160 000 ha globally and the loss of direct employment for approximately 240 000 banana workers. -

An initiative of the World Banana Forum
2020TR4 Global Network. An initiative of the World Banana Forum is the corporate brochure of the TR4 Global Network (TR4GN). It showcases the role of the Food and Agriculture Organization (FAO) of the United Nations as a leader in global efforts to combat the spread of Tropical race (TR4), a fungus that is ravaging banana and plantain farms on three continents. The audience for the corporate brochure is primarily policy-makers and decision-makers, but it is also relevant to experts, academia, students, the media and the general public. Along with a historical look at the disease affecting bananas and plantains, the brochure clarifies the globally recognized terms used to discuss TR4. That is, it differentiates between: the disease (Banana Fusarium Wilt); the fungus (Fusarium oxysporum f. sp. cubense); and the current strain of fungus (Tropical race 4 or TR4). Key takeaways listed in the brochure include: there is currently no cure for TR4; TR4 can be transmitted through shoes, vehicles, farm tools and equipment, but also through drainage water, surface run-off water and floods; the most effective approach to combat TR4 is prevention of its spread into clean areas and immediate containment once it is detected; diversification of banana and plantain crops and agroecological practices that support sustainability are also key to help prevent TR4; and both international collaboration and local actions are essential to manage TR4 in affected countries. -

2020Preventing the spread and introduction of Banana Fusarium Tropical race 4 (TR4) disease is a summary of a more extensive guide for travellers, targeting occasional and regular travellers to or from banana and plantain production areas. The quick guide aims to raise awareness and provide direction on preventing the spread of the highly virulent pathogen known as Tropical Race 4 (TR4. The document opens with a brief historical background on the banana fusarium wilt disease that have affected banana and plantain plants over several decades. Today, TR4 threatens almost all banana and plantain producers, posing the greatest risks to countries producing Cavendish bananas in monoculture plantations in Asia, Australia, Africa, the Near East, Latin America and the Caribbean. Once established in a banana or plantain plantation, the fungus can survive in the soil and in alternative host plants for decades. Finally, the quick guide offers recommendations: for regular and occasional travellers and local or international visitors; for farmers, professionals, technicians and employees visiting disease-free banana and plantain farms in areas where TR4 infestation has been recorded; and additional recommendations for visiting farms infested with TR4 for obligatory and work-related reasons.
