Cassava brown streak viruses (cassava brown streak disease).

Abstract

CBSD was formerly of limited importance in Africa as a whole because of its restricted distribution along lowland coastal areas of Kenya and Tanzania and in parts of Malawi (Legg and Raya, 1998; Hillocks et al., 2001; Gondwe et al., 2003; Shaba et al., 2003). However, the disease was later found to be prevalent in northern Mozambique (Hillocks et al., 2002). Since 2004 it has been causing increasingly severe problems in Uganda and the Lake Victoria zone of Tanzania. It has also been detected recently in Rwanda, Burundi and parts of DRC.
