Low potato yields in Kenya not down to management practices alone, CABI study suggests

Stepping up the fight against devastating potato diseases in Kenya

Surveillance of potato diseases in Kenya

Potato is one of the most widely grown crops in Kenya. The sector contributes almost USD 30m per year and employs 3.3 million people.  However, the yield has been reducing significantly over the last decade, 12.4 t/ha below the global average of 21 t/ha. This has been attributed to a number of problems but the most important being the high incidence of pests and diseases, some of which are seed and soil-borne. CABI is conducting a surveillance exercise to identify and map the distribution of Pectobacterium and Dickeya species which cause blackleg and soft rots and Clavibacter michiganensis subsp. sepedonicus which causes ring rot. The results from the study will advise on the required regulatory framework for the certification of seed potato and provide information for better management and control.
