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...
