EFSA - 2008 - Pest risk assessment made by France on Fusarium oxysporum. f. sp. cubense considered by France as harmful in French overseas departments of French Guiana, Guadeloupe, Martinique and Réunion. Following a request from the European Commission, the Panel on Plant Health was asked to deliver a scientific opinion on 30 pest risk assessments made by France on organisms which are considered by France as harmful in four French overseas departments, i.e.
French Guiana, Guadeloupe, Martinique and Réunion. In particular, the Panel was asked whether these organisms can be considered as harmful organisms for the endangered area of the above departments, in the meaning of the definition mentioned in Article 2.1.

</b></div></div> Article. PROMUSA - Tropical race 4. Tropical race 4 (TR4) is the name given to the fungal strains of Fusarium oxysporum f. sp. cubense (Foc) that cause Fusarium wilt (popularly known as Panama disease) in Cavendish cultivars grown in tropical conditions.
The term TR4 was coined to distinguish these strains from the ones that cause the disease in the presence of predisposing factors, such as low temperatures, and have since become known as subtropical race 4 (STR4). The term TR4 usually refers to isolates belonging to a particular vegetative compatibility group called VCG 01213/16, although other VCGs have also been shown to cause Fusarium wilt in Cavendish cultivars. It should be noted that TR4 has a wider host range than just Cavendish bananas.
In addition to hitherto unaffected varieties, it also causes disease in groups of cultivars susceptible to races 1 and 2, such as Gros Michel, Silk, Pome and Bluggoe. TR4 was first identified in the early 1990s. Distribution Host range Symptoms and diagnosis. Le site PANAMA DISEASE_ORG. Panama disease is caused by the fungus Fusarium (the full name is Fusarium oxysporum f. sp. cubense).
It is a soil pathogen which infects the root system and goes on to colonise the plant through the vascular system – hyphae of the fungus can even reach the leaves. The disease cannot be controlled or cured other than by soil treatments, which unfortunately have such a detrimental effects on the environment that they are prohibited almost everywhere.Biological methods under development are showing great potential, however. One of the worst effects of Panama disease is the production of so-called chlamydospores , or resting spores, which survive in the soil for decades.
As soon as a susceptible banana plant is grown nearby, these spores germinate, infect the plant, and kill it. Nouvelles: La FAO presse les pays d’intensifier la lutte contre une maladie qui ravage les bananeraies. Plants de bananes atteints par la maladie 14 avril 2014, Rome – La FAO exhorte les pays à intensifier la surveillance, la notification et la prévention de la jaunisse fusarienne, une des maladies les plus destructrices de la planète pour les bananiers, qui s'est récemment propagée de l'Asie à l'Afrique et au Moyen-Orient et menace de s'étendre aux pays d'Amérique latine.
Selon une note d'information de la FAO, la souche Tropical Race 4 (TR4) de la maladie, également connue sous le nom de maladie de Panama, constitue une sérieuse menace pour la production et l'exportation de ce fruit très apprécié et pourrait avoir de graves répercussions sur la filière et les moyens d'existence. La banane est considérée comme la huitième culture alimentaire mondiale, et comme la quatrième dans les pays les moins avancés, selon FAOSTAT, le principal service de collecte et d'analyse de données de l'institution des Nations Unies.
Mesures recommandées Au niveau des pays, la FAO conseille en particulier: WIKIPEDIA – Fusarium oxysporum f.sp. cubene. Fusarium oxysporum f.sp. cubense is a fungal plant pathogen that causes Panama disease of banana (Musa spp.), also known as fusarium wilt of banana.
Overview Although fruit of the wild banana, Musa balbisiana have large, hard seeds, these have been bred out of the modern culinary banana which is seedless. Banana plants are therefore propagated asexually from offshoots. Because these rhizomes are usually free of symptoms even when the plant is infected by F. oxysporum f. sp. cubense, they are a common means by which this pathogen is disseminated.
It can also be spread in soil and running water, on farm implements or machinery. SPC - MARS 2005 - Fusarium Wilt (Panama Disease) of Banana. WIKIPEDIA - Panama disease. Panama disease is a plant disease of the roots of banana plants.
It is a type of Fusarium wilt, caused by the fungal pathogen Fusarium oxysporum. The pathogen is resistant to fungicide and cannot be controlled chemically. In the 1950s, Panama disease wiped out (except in Asia) the Gros Michel banana, the dominant cultivar of bananas, inflicting enormous costs and forcing producers to switch to other, disease-resistant cultivars. However, new strains of Panama disease threaten the production of today's most popular cultivar, Cavendish. Susceptibility The fungus causes significant damage to banana crops due to its virulence, as well as the identical genetic composition of modern banana crops. History Gros Michel devastation era Gros Michel was the only type of banana eaten in the United States from the late 19th century until after World War II. The response Scientists took several years to identify the problem. Cavendish devastation era See also Proc Natl Acad Sci U S A. 1998 Multiple evolutionary origins of the fungus causing Panama disease of banana: Concordant evidence from nuclear and mitochondrial gene genealogies.

This PhD project is one of the components that will be integrated with the other projects to manage Panama disease and maintain a viable banana production - both industrial and subsistence - even in TR4 infested areas.
For example, this study will identify where certain banana cultivars should not be grown due to the pathogenicity of the indigenous Foc diversity and quantity. Throughout history, few plant disease epidemics have devastated production of an agricultural commodity as severely as Panama disease, i.e. EFSA - 2008 - Pest risk assessment made by France on Fusarium oxysporum. f. sp. cubense considered by France as harmful in French overseas departments of French Guiana, Guadeloupe, Martinique and Réunio.
