Abstract: A survey of Champawat district of Uttaranchal, India was conducted to record the plant parasitic nematodes associated with some vegetable, cereal, oil-seed and fruit crops.

The M. incognita and M. javanica were found to have highest importance value (53.2), followed by R. reniformis (47.24) and H. seinhorsti (44.08), and these were adjudged to be the top ranking plant parasitic nematodes in this district This is the first attempt of a nematode-based survey of Champawat district of Uttaranchal.
