Titre : Surveillance of potato diseases in Kenya

Région /Pays : Kenya

Potato is one of the most widely grown crops in Kenya. The sector contributes almost USD 30 million 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 cause ring rot. The results from the study will advise on the required regulatory framework for the certification of potato seed and provide information for better management and control.

* Develop the surveillance protocol in line with international standards * Determine Kenya’s disease situation for different ecological zones * Identify areas (if possible) in selected counties with potential to grow disease-free planting material * Enable prioritization of regulatory actions needed in interventions as part of official controls in seed multiplication and supply systems for Kenya * Support objective analysis of the current regulatory framework for certification of seed potato and develop/apply control/prevention measures necessary for quality assurance elements of seed health management strategy * Generate data and develop information that spells out risks and mitigation measures in seed supply systems (production, multiplication, and distribution) for industry actors and farmers * Make the above information available in a way that it can be disseminated to key stakeholder groups : policymakers, research institutions, the large-scale private sector involved in (seed) potato production as well as small farmers

The main aim of this project is to determine the existence, prevalence and severity of potato ring rot, blackleg and soft rot causing pathogens – Clavibacter michiganensis subsp. sepedonicus which causes ring rot and Pectobacterium and Dickeya species which cause blackleg and soft rots. The information gained is important to achieve the following ; detect and monitor the threat of target pathogens in order to prevent their introduction and management if present or if they become present in the Kenya ; support market access and trade in potato by providing surveillance information on the status of target pathogens ; promote trading partners’ confidence by ensuring the availability of current and reliable information on the status of the target pathogens in Kenya ; update the regulated pest list and technically justifiable import requirements for the host commodity.
