Surveys of the incidence of African cassava mosaic disease (ACMD) and its whitefly vector, Bernisiu tabaci, were made at three-month intervals in 1992 and 1993 along two South-North transects. One was in central and the other in eastern Uganda. ACMD incidence was high within the northern localiti...

Cassava mosaic disease (CMD), and cassava mosaic geminiviruses (CMGs), were investigated in a country-wide survey conducted in six cassava-producing prefectures (administrative regions) of Rwanda in 2001. CMD occurred throughout the country at an average incidence of 30%. Incidence was highest in...

Cassava is well recognized for its capacity to address food needs of vulnerable communities in unstable environments in SSA. IITA and colleagues in African NARS, in collaboration with CIAT and ARIs have played leading roles in the development of improved cassava varieties which are disease and pe...
