Cassava brown streak disease in northern Mozambique.

Abstract

Cassava brown streak disease (CBSD) of cassava ( Manihot esculenta ) caused by cassava brown streak virus (CBSV) has been known in Tanzania since the 1930s, but has not been recorded previously in Mozambique. A virus disease survey of cassava was undertaken, therefore, in 1999 in Zambezia and Nampula Provinces, which are the main areas of production in Mozambique. During the survey, CBSD was identified for the first time in these areas of Mozambique. Disease incidences in some fields in coastal areas reached 80-100% and many of the main cassava cultivars were affected. Cassava is the staple crop for most of the rural population in northern Mozambique where food security is threatened by these high incidences of CBSD.
