Epidemiological Assessment of Cassava Mosaic Disease in a Savanna Region of the Democratic Republic of Congo

An epidemiological survey was conducted, from September 2009 to January 2010 in 206 famers’ fields located across 21 cassava-growing localities of Ngandajika territory Lomami province (central part Democratic Republic Congo (DRC), determine distribution and status Cassava Mosaic Disease (CMD). Parameters related the identification evaluation CMD (incidence, severity gravity) number adult whitefly vector were assessed. present all surveyed varied according varieties. incidence low at INERA station (4.33%) but high Kafumbu (74.55%). (1.09) (2.67). Gravity (2.99%) elevated Quartier (67.82%). The mean populations with sites. However, whiteflies more abundant Mpunga (3.65) compared (1.09). Overall, 71 % varieties showed varying degrees sensitivity CMD. results this study revealed that health cassava is alarming deserves sustained intervention. Adequate effective control methods must be place reduce inoculum levels speed propagation limit yield losses caused by disease.
