Roots and soil samples collected from different locations were analyzed for the nematode. The results showed 64.93% samples infected with the nematode. Maximum infection (81.66%) was recorded in Malakand agency followed by Mardan, Peshawar and Nowshera showing 79.16%, 66.66% and 64.44% infection respectively.
