In recent years, there has been an increase in the number of diseases caused by phytopathogens. These pathogens affect plants at different stages of their growth and agricultural production. Depending on weather conditions and the phytosanitary condition of crops, the prevalence of diseases can reach 70-80% of the entire plant population, and yields can decrease in some cases by 80-98% [1]. Plants have intracellular immunity, but specific phytopathogens are abletoovercomeit. The article presents a brief description of nematode species, theirimpacton the reduction of yieldand quality of watermelon varieties "Marmar" (Marble). A comparative study of nematode of the settlements "Juraboy Darkhan" and "Ozod Darkhon" of the Akdarya district of the Samarkand region was carried out.
