Mainly grown in the highlands of Kenya, potatoes are an important staple food and cash crop and play a significant role in national food security, nutrition, poverty alleviation and income generation. In 2015, Potato Cyst Nematode (PCN) was first detected and confirmed in Kenya, posing a serious threat to potato farmers, most of whom are smallholders in rural areas. If uncontrolled, PCN can lie dormant in soil for 20 years and cause up to an 80 percent reduction in Kenya’s potato yield. Therefore, the Government requested emergency assistance from FAO to take immediate measures to identify and halt further spread of the pest, as well as to develop a long-term management and control strategy.
