Plant distress symptoms and resulting yield reductions can be caused by infection when environmental stresses are placed on the plant. In this investigation, samples of Spinach and Mentha were taken from various parts of the Godumakunta village in Keesara Mandal (M), Telangana. In this study, certain nematodes were found in the leafy vegetables spinach and menthe grown soil. Psilenchus dunensis, Belonolaimus longicaudatus, Tylenchorhynchus brevilineatus,, Peltamigratus indicus sps, Hoplolaimus indicus sps, and Aorolaimus perscitus sps, were identified in Spinach and Mentha grown soil. Radopholus found in the soil of Spinach and Criconemella in the soil of Mentha. In the soil analysis for these vegetable crops, pH was 7.5 in Spinach grown soil and pH was 7.8 in Mentha grown soil. Color, texture and salinity were the main factors that determine phytonematodes population. Among the different leafy vegetables examined, Micrococcus roseus, Cellulomonasterrae, Bacillus cereus, Pseudomonas fluorescens, Rhizopus microspores, Azospirillumbrasilense, Aspergillus niger, Fusarium oxysporum, Curvulariaclavata, Penicillium chrysogenum were found in every one of them. Low numbers of Hoplolaimus indicus were found in the leafy vegetables while high numbers of Aorolaimus perscitus were found in leafy vegetables. Our studies revealed that different phytonematodes' diversity changes based on the type of plants. This diversity is more on the root's physiological nature. Based on these outcomes, one can develop methods to control phytonematodes.
