Integrated Management of Potato and Sweet Potato Viruses


Alleviate economic, human health and environmental hardships caused by potato and sweetpotato viruses.


To develop, evaluate and implement, in collaboration with NARS and with farmers' participation, disease management alternatives that are appropriate for resource poor farmers; help NARS researchers build capacity for applied research; develop learning resources for researchers, extension workers and farmers.

Below is a brief description of this research conducted by the Virology Team headed by Dr. Luis F. Salazar until Decemer 31st, 2006, now headed by Dr. Ian Barker.   Though major virus activities are included in the Division 4, members of the team participate or lead activities/subprojects in Divisions 2, 3, and 5.

A BRIEF DESCRIPTION OF THE RESEARCH Other specific objectives include:

a.    Develop and deploy technology for virus diagnosis.

b.    Search for virus resistance genes and understanding the basis of host resistance to viruses.

c.    Identify new virus pathogens that may emerge in the crops of interest to CIP.

d.    Assist other activities in CIP where virus or virus-related technology can be applicable.

e.    Assist other institutions to develop tools to control virus diseases in crops other than potato or sweetpotato.

Expected Outputs by 2008


In Peru, China, Indonesia, Kenya, Ethiopia and ESEAP and SSA regions.

Potential Impact(s) (Benificiary/ies)

Beneficiaries of the project are potato farmers in mid-elevation regions of Peru, Bolivia, Kenya and Uganda and sweetpotato farmers in Peru, China, Indonesia, Uganda and Kenya. Intermediate users (secondary beneficiaries) are NARS, NGOs, and farmers' associations that are involved in potato and sweetpotato production and research that whose capacity will be strengthened or built from collaborative research and CIP's training and backstopping; and especially national potato and sweetpotato "seed" programs and potato seed certification agencies worldwide that will benefit from the distribution of CIP's BW and viruses detection kits for seed testing.

The development of sound and economically rational set of IDM recommendations and increased farmers' knowledge on disease epidemiology and control will contribute to improve farmers' livelihoods, food security and income.
