3 October 2019, Rome - The Food and Agriculture Organization of the United Nations (FAO) has launched an emergency project under its Technical Cooperation Programme to help countries in Latin America and the Caribbean fight the spread of Fusarium wilt, a fungal plant disease that can wipe out the banana crops upon which the livelihoods of millions of people depend.

 

The disease - caused by the most recent strain (Tropical Race 4, TR4) of the fungus Fusarium oxysporum f.sp. cubense - affects the production of many varieties of plantains and bananas, including Cavendish, one of the globally most popular varieties in the market. TR4 damages the roots and stems of the plant and, while not harmful to human health, can lead to 100 percent yield losses, making it a major concern for countries and communities where banana production is a critical source of food, household income, and export revenues.

 

TR4 was recently detected for the first time in Latin America and the Caribbean in Colombia, where 175 hectares of banana farms have now been put under quarantine by the Instituto Colombiano Agropecuario (ICA). Nearby Ecuador is the world's largest banana exporter, while Colombia, Costa Rica, and Guatemala are also major producers. If the disease spreads, it would have devastating impacts for farmers and their families across the region.

 

"The role of bananas in providing food and household income in this region cannot be understated. In several countries, this crop has national economic importance, as it is a major export. Together, we can curb the spread of this devastating disease, and protect livelihoods," said FAO Assistant Director-General and Regional Representative for Latin America and the Caribbean, Julio Berdegué.

 

"This emergency project will assist countries in developing regional and national action plans, increasing their capacities to prevent, diagnose, monitor and contain outbreaks, and raise awareness and disseminate information among farming communities," he added. "National governments, like those of Ecuador and Colombia, are providing active and intelligent leadership, and we are solidly behind them."

In addition, the new TR4 wilt project for Latin America and Caribbean also aims to support greater collaboration and experience-sharing among the countries in the region.


These activities will be conducted, under the leadership of national governments, in a coordinated effort with relevant phytosanitary institutions, including national and regional plant protection organizations (CAHFSA, CAN, COSAVE, OIRSA) as well as the International Plant Protection Convention (IPPC) Secretariat.

 

Limiting the disease's spread

TR4 is a pathogen that can be transmitted through movement of infested planting materials, contaminated soil, water or other physical means such as shoes, tools and tyres. Once established, the pathogen remains in the soil for decades; currently there is no way to eradicate it completely.

 

However, measures do exist that can be effective in limiting the spread of the disease, including: implementing appropriate preventive and phytosanitary measures, establishing the right regulatory environment, raising awareness, building multi-stakeholder collaborations, engaging with the private sector and smallholder farmers, supporting increased biodiversity, improving the effective use of genetic resources, developing disease management and recovery programmes, and improving monitoring and early action.

 

"Countries must be vigilant in monitoring and containing any TR4 cases. Only strict observation of phytosanitary measures can prevent the disease from spreading. Concerted local and regional efforts, scientific support, early detection and international collaboration are crucial to combat TR4," said Hans Dreyer, Director of FAO's Plant Production and Protection Division.

 

FAO's response

Even prior to the launch of the new project in Latin America and the Caribbean, FAO has been providing technical assistance to affected countries to limit the spread of the disease.  This includes policy and technical guidance to assist them in prevention and diagnostics, and in identifying risk pathways.

At the international level, FAO is establishing a global network on TR4 under the World Banana Forum, the multi-stakeholder platform of the banana sector, which the Organization facilitates. The network will help coordinate actions and disseminate technical advice from specialized bodies, including the Forum's TR4 Task Force.

 

Additionally, the International Plant Protection Convention (IPPC), whose Secretariat is hosted by FAO, also recently convened a workshop in Colombia for agricultural experts from 16 Latin American countries on plant health including best practices to prevent the spread of Fusarium wilt.

 

Protection through diversity

The Cavendish banana variety makes up around 47 percent of global production.

 

Diversification, soil health and better use of available genetic resources are key to building resilience to the disease in the long term. Threats to the Cavendish may encourage farmers, and the private sector, to move away from monocropping towards more biodiverse plantation systems using some of the 1,000-plus other banana varieties.

 

Note to Editors: the correct full name for the disease is banana Fusarium wilt disease (or Fusarium oxysporum f.sp. cubense). It is occasionally incorrectly referred to as Panama Disease, and this name should be avoided.
