Scientists at CGIAR-IITA, working with the International Centre of Insect Physiology and Ecology (icipe) under the joint Nematology Unit, NemAfrica, housed at icipe’s campus in Nairobi, and their national and international partners, have been at the forefront of efforts to address a new emerging pest threat to the production of potato in the East Africa region, and in many other countries in the world.
These are the parasitic microscopic worms known as Potato Cyst Nematodes (PCN). These destructive pests attack potato roots and can cause yield losses of up to 80%, and in some instances, even total crop failure.
