Incidence and severity of African cassava mosaic

The objective of this study was to contribute to the improvement of cassava production in the Mbanza-Ngungu region. Specifically the study aimed to assess the incidence and severity of African cassava mosaic in farmers'' fields in the Luvaka group. Thus a survey was conducted in six localities of the Luvaka group: Kiwonso Mpete Kimuingu Langa Masielele and Luvaka in order to assess the incidence of mosaic disease. Results showed that the RAV variety is less susceptible to African cassava mosaic than the other cultivated varieties. The Kiwonso locality showed the lowest incidence (60%) compared to other localities. In view of these results it can be seen that the cassava varieties cultivated in the Luvaka group do not have the same behavior towards African cassava mosaic.
