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. -

Guide for travelers
2020Banana is an important crop for food security and ensuring the livelihoods of approximately 400 million people who depend on the crop either as a staple food or source of income, particularly in Asia, Africa, Latin America, and the Caribbean. Plant pests and diseases can seriously affect agricultural production and livelihood of rural people. Fusarium wilt of banana is one of the key examples of crop devastation by a plant disease. This disease brought the banana export industry almost to a halt in the 20th century when the popular banana variety Gros Michel was devastated in Central America. The sector was saved by the introduction of the Cavendish variety, which is resistant to race 1 of the fungus. However, Cavendish bananas are now succumbing to a new, highly aggressive strain of the Fusarium wilt fungus, Tropical race 4 (TR4). Fusarium wilt TR4 threatens almost all banana 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. Cavendish bananas, which constitute approximately half of the bananas grown globally are highly susceptible to TR4, but other dessert banana varieties grown in these regions are also susceptible. Once established in a banana plantation, the fungus can survive in the soil for decades with its chlamydospores, even without banana plants. Scientific reports indicate the presence of TR4 in numerous countries in Asia (China – mainland and Taiwan Province), India, Indonesia, Israel, Jordan, Lao People’s Democratic Republic, Lebanon, Malaysia, Myanmar, -
ProjectBuilding Regional Surveillance, Prevention and Management Capacities to Combat the Possible Spread of Fusarium Wilt Caused by Fusariumoxysporumf.sp.cubense Tropical Race 4 Fungus (FOC TR4) - TCP/RLA/3724 2022

Bananas are the world's fourth most important staple food and an important consumption and export item in RLC, a region that is home to six of the world's top ten exporters and three of the world's top producers Banana Fusarium Wilt, caused by the fungus Fusarium oxysporum f sp cubense Foc is one of the most destructive banana and plantain diseases worldwide and a serious threat to the RLC region Tropical Race 4 Foc TR 4 has caused severe losses in southeast Asian countries with serious repercussions for smallholders, workers and the banana value chain It is estimated that without consistent and coordinated action between and among countries, this pest could affect more than 1 6 million ha by 2040 The Foc TR 4 can be spread by infested plant materials, spores and soil particles attached to agricultural tools, shoes, vehicles and other means Irrigation and water drainage, particularly flooding, plays a critical role in its spread Controlling its spread requires the strengthening of country prevention and surveillance systems, but also a commitment to international coordination in order to develop and implement collective protection strategies There is therefore a need to i formulate a regional action plan for Foc TR 4 prevention, surveillance and eventual response ii) develop and adopt national action plans for Foc TR 4 response, surveillance and prevention and iii) build capacities to contribute to Foc TR 4 prevention, response and surveillance, as essential elements for ownership and sustainability of all these actions.
