Caribbean banana farmers are abandoning fields where crops have been badly affected by Black Sigatoka disease. Black Sigatoka has badly affected several countries in the region, including Dominica, St. Lucia, Grenada and Guyana. Black Sigatoka is considered the most destructive disease of bananas and plantains and is caused by the fungus Mycosphaerella fijiensis. It first arrived in the Caribbean in 1991, and has since established and spread throughout the region.   Severely infected leaves die, significantly reducing fruit yield and causing mixed and premature ripening of banana bunches.  As part of the response to Black Sigatoka outbreaks in the Caribbean the Food and Agriculture Organisation of the United Nations (FAO) provided an intensive training programme in management of the disease in Dominica back in June this year. The workshop trained technicians from Dominica, St. Lucia, Grenada, Guyana and St. Vincent and the Grenadines. The Caribbean’s tropical climate with high rainfall and high humidity is conducive to the spread of Black Sigatoka, hence the training program focused on the management of the disease, including the strategic and careful use of fungicides in order to manage the disease while aiming to prevent fungicide resistance developing. Last year, FAO provided an expert from Cuba to assess the management efforts of each country in the Caribbean affected by the disease, and identify areas for improvement. For each country, a management and action plan was created in conjunction with the CARICOM Secretariat, the OECS Secretariat, the Caribbean Agricultural Research & Development Institute (CARDI), Inter-American Institute for Cooperation in Agriculture (IICA), CIRAD, the Ministry of Food Production in Trinidad & Tobago and the Banana Board of Jamaica.

There are factsheets available on Black Sigatoka and it’s management on the Plantwise Knowledge Bank, with factsheets in French, Spanish and English. Click here to see them.
