CBSD control strategy in the region

West Africa, Peter Kulakov, IITA head of cassava breeding: “The institute and its partners are working on measures to prepare in the event the disease spreads to the region. Extensive breeding is underway that includes hybridization of local varieties with those from eastern Africa that have been known to have resistance.”

Southern Africa, Pheneas Ntwaruhunga, SARRNET coordinator: “In South African countries, the disease was reported a long time ago in both Mozambique and Malawi. In my visits around Malawi I have seen the disease is increasing and I am particularly concerned as it is now attacking the main variety that the farmers are growing. However, breeding for resistant varieties is underway incorporating germplasm from varieties showing resistance from neighbouring countries to transfer resistance or tolerance to the local varieties.”

“In Mozambique, the NARS had released four varieties which were tolerant to the disease and the pressure was now greatly reduced. In Angola and Zambia so far there have been no confirmed cases of CBSD.”
