Summary for Project title: R8484: Identifying Insect Vectors and Transmission Mechanisms for Banana Xanthamonas Wilt to Improve Understanding of Disease Epidemiology.

Farmers are controlling a major banana disease, Xanthomonas wilt, by preventing the entry of insects that carry a bacterium (Xcm) that causes the disease. Removing male buds from the plants is one solution. Another is the destruction of infected plants to keep them from continuing to attract insects. Finally, by opting for banana varieties in which the male flower cushions have a natural protective covering farmers make their crops inaccessible to the insect vectors. These findings were made possible thanks to the identification of an improved medium for isolating Xcm from insects, soil, and plants. The new control techniques are being promoted in Kenya, DR Congo Republic, Rwanda, Tanzania, and Uganda using participatory methods.
