News on Potato Defects and Diseases from Kenya

Kenya nears release of '3R' Late Blight-resistant potatoes after 20+ years of research by CIP & KALRO. Supported by 2Blades, Feed the Future & Simplot, the varieties promise higher yields, disease protection, and improved food security by 2026.

The James Hutton Institute introduced two PCN-resistant potato varieties, Malaika and Glen, in Kenya. Developed with international partners, they boost yields, support food security, and meet local farmers’ needs for fast-cooking, low-dormancy potatoes.

IITA, FAO & partners equip 12 African nations to detect/manage Potato Cyst Nematodes, a pest slashing yields & threatening trade, via training, diagnostics, awareness & regional cooperation to protect farmers’ livelihoods & potato production.

The 13th World Potato Congress will be held in Naivasha, Kenya, from October 26–30, 2026—the first in Sub-Saharan Africa. Hosted by NPCK and FreshCrop Ltd, the event will spotlight global potato innovations, food security, and trade.

Solynta's potato varieties with high resistances against Late Blight provide Kenyan farmers with good yields, as demonstrated in a comparative field test during an extensive spray/no spray trial in Limuru, Kenya.

Free smartphone app Nuru helps African potato farmers to detect late blight (Phytophthora) and early blight (Alternaria) since 2021

With potato production in East Africa under increasing threat from the invasive and highly destructive potato cyst nematode (PCN) pest, an organic technology developed from banana plant waste material may well be the ultimate rescue.

Demand for potatoes in eastern Africa has been growing steadily. This growth is driven in part by rising demand from the fast food industry and for processing into high value products such as crisps, chips and starch. Despite an increase of 60% in the area of cultivated land, production has been declining in Rwanda, Kenya and Uganda.

Kenyan farmers are facing a shortage of certified seed potatoes following the rejection of 78 percent of the planting materials that had been imported last year.

Based on extensive trials (two years, three separate farms, ten potato varieties) in a joint effort of AHDB, James Hutton Ltd, SASA and Seeds2B Africa (part of the Syngenta Foundation) three GB potato varieties have been recommended for release in Kenya.

A survey done in 20 counties in Kenya released earlier this month, shows that Potato Cyst Nematode infestation has reached 80 to 100 per cent in some of the potato growing areas.

Nakuru will test and release (late blight resistant) varieties of potato seeds for small-scale farmers, Agriculture executive Dr Stanley Chepkwony has said.

Njoroge is studying a new lineage of Phytophthora infestans called KE-1 that is spreading rapidly across East Africa.

East African farmers, who are mostly small-scale, currently select their seed potatoes from the mass of harvested potatoes. That results in lots of virus diseases and potato brown rot, as well as low yields of an average of 10.5 tons per hectare. Tha...

Potato Farmers in Kenya have opposed a decision by the government to import seed from the Netherlands, insisting that the move will kill the little but growing initiative to produce clean planting seed potato and will expose the country to potato disea...

A major controversy has broken out over government plan to import seed potato favoured for the production of high quality crisps and chips.

SCRI is leading an international project to help potato farmers in Kenya.The mission is being supported with a grant from the Monsanto Fund totalling £186,000. The ambition is to increase potato yields - and importantly Kenyan farmer's incomes.
