    Tropical Race 4 prevention strategies
    TR4 Global Network. An initiative of the World Banana Forum

    Managing the movement of soil, water and plant material entering and exiting farms is the key to effective on-farm biosecurity. Prevention is currently the primary way to avoid new Tropical race 4 (TR4) invasions. Intended for a development practitioner audience, TR4 prevention strategies, details, step by step, how early detection, rapid destruction of infected banana and plantain plants, and on-farm restrictions are the only way to control and contain TR4. A country’s regulatory framework is explored in this document, with, for example, the following steps to be taken: designation of TR4 as a quarantine pest; setting up a monitoring system to promptly detect incursions; enacting of regulations that allow the National Plant Protection Organisation (NPPO) to intervene on farms. On-farm biosecurity is only effective if the standard for practices are high, and if practices are adhered to at all times. A single practice failure can potentially lead to the introduction of a new pest or disease. With this in mind, ten biosecurity measures are listed, which if enforced, enable farmers/growers to help to protect not only their own farms, but also their country's banana industry. In addition, practical and detailed steps for farm visitors and for international travellers are included in the document.

    For Armenia, Belarus, Bosnia and Herzegovina, Georgia, North Macedonia, Republic of Moldova and Ukraine, plant protection in agriculture and forestry is important for food safety and economic development Not only do plants ensure sustainable nutrition for society, but they also support international trade in plants or plant products As plants are hosts for many pests, international trade is inherently associated with risks of pest introduction and spread National phytosanitary systems based on the International Plant Protection Convention ( and International Standards for Phytosanitary Measures ( aim at reducing those risks Even though the ISPMs are available on the website of the IPPC, National Plant Protection Organizations ( often have insufficient knowledge of them In practice, this may translate into difficulties in discussions with other NPPOs, especially on trade related issues Moreover, as ISPMs are revised and updated, especially to reflect new scientific achievements, periodic training is necessary to keep NPPOs and their officers informed about recent developments The main objective of this project was to enhance the capacities of the national phytosanitary systems operated by the NPPOs of the recipient countries to better prevent the risks associated with the introduction and spread of pests that can occur through international trade in plants and plant products Among the key elements of national phytosanitary systems are surveillance systems, which enable reliable determination of the presence or absence of pests in the territories or parts of territories of countries, early detection of newly introduced pests and determination of areas of their spread within the country Monitoring surveys are used to verify the characteristics of pest populations within countries, enabling timely reaction and the prevention of economic damage to crops The project built the capacities of the NPPOs in the participating countries on the identification of pests and on phytosanitary certificates through the delivery of training sessions These were based on international standards adopted under the IPPC, which provide guidance for NPPOs around the world on the harmonization of their actions to combat plant pests for international trade in plants and plant products.

    Building 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.
