Survey of plant-parasitic nematodes was conducted in different cropping areas of Telangana state during 2009-2012. Different genera of plant-parasitic nematodes were found in association with economically important crops causing great damage to agricultural production. We recorded the presence of ten genera of plant-parasitic nematode occurring in the different cropping areas showing much species diversity. In our present investigation, we aimed to know the Relative frequencies and Absolute frequencies of plant-parasitic nematodes. Meloidogyne species were more pre-dominant and recorded with highest relative frequency and absolute frequency in our survey.
