Vidarbha region of Maharashtra comprising of two divisions i.e. Amravati and Nagpur was surveyed for locating high density spots of plant parasitic nematodes, Rotylenchulus spp.. About 737 soil samples were collected from 16 crop systems in 119 talukas and evaluated for presence of plant parasitic nematodes. In literature, amongst the genera of plant parasitic nematodes, threshold levels of damage have been standardised for only 5 genera. Mapping of plant parasitic nematodes was done crop ecosystem wise. Reniform nematode, Rotylenchulus reniformis was the most prevalent and predominant nematode species. This may be attributed to the fact that major crops of the region viz. Cotton, Soybean and pigeon pea are also good hosts for this nematode. The areas where the population exceeds the threshold of damage (200/100cc soil) for reniform nematode R. Reniformis were identified and mapped. Maximum number of samples from Cotton crop showing high population density of reniform nematode was recorded in Yavatmal district followed by Buldhana while population was less in Nagpur and Gadchiroli. For Pigeon pea crop also high density spots were recorded highest in Yavatmal followed by Buldhana and Amravati with lowest in Gadchiroli. Variation in population density may probably be correlated to gradual spread of irrigation availability through drip irrigation.
