District Bajaur is a newly merged District of Khyber Pakhtunkhwa Pakistan. The total areas of Bajaur are 129035 hectare. It is located at an elevation of 1152 meters above sea level. The total land under agriculture is 77166 hectare. In Bajaur the cultivated field under irrigation covers approximately 2739.22 hectares and over 74426 hectares is barani (irrigated) and around 20003.99 hectares is uncultivated. Of the total cultivation fields Three fourths depends upon precipitation and managed by farmers. The current study was carried out in twelve different location of district bajaur KPK Pakistan. Four zone were selected from district bajaur on the bases of mountainous areas, plane areas, availability of water and soil fertility; Total 200 soil samples were collected from the study area during August 2018 to September 2020 for diagnosing the nematode problems. Out of 200 samples seven new record species were identified viz., Aphelenchoides shamimi Khera 1970; Filenchus uliginosa (Brzeski, 1977) Siddiqi, 1986; Helicotylenchus africanus (Micoletzky, 1916) Andrassy, 1958; H. digitiformis Ivanova, 1967; Psilenchus curcumerus Rahaman, Ahmad & Jairajpuri, 1994; Pratylenchus wescolagricus Corbett, 1984; Tylenchorhynchus hordei Khan1972.
