The article presents information about phytonematodes of potato agrocenoses of Samarkand region. As a result of research, 67 types of phytonematodes were identified in potato agrocenoses. According to the categories, representatives of Rhabditida, Dorylaimida and Tylenchida dominate, Aphelenchida is relatively rare, Mononchida, Chromadorida, Plectida and Enoplida are rare. In relation to the stems, leaves and roots of the potato crop, phytonematodes were found in the soil around the roots. Depending on the degree of occurrence of phytonematodes in plants and soil, they are divided into eudominants, subdominants, subdominants, residents, subresidents, and subresidents (70%) are the majority. According to the ecological groups, phytonematodes are dominated by pararhizobionts and devisaprobionts, non-pathogenic phytohelminths are in second place, eusaprobionts are in third place, and real parasites are in the last place. Species diversity in phytonematode fauna was observed in potato agrocenosis planted after cabbage crop in Okdarya district, and the maximum number of individuals was recorded in agrocenosis planted after potatoes in Tailoq district. The least number of phytonematodes was recorded in potato agrocenosis in dry soils planted after hot pepper in Jomboy district. Among the parasitic phytonematodes of potatoes - Bitylenchus dubius, Rotylenchus goodeyi, Helicotylenchus erythrinae, H. multicinctus, Pratylenchus pratensis, P. macrophallus and Ditylenchus dipsaci species were recorded.
