Online published on 15 December, 2016. Abstract Banana is one of the major commercial fruit crops, ranking first in fruit production in the world. The crop is affected by several disease caused by fungi, bacteria, viruses, nematodes andbiotic factors. Among plant parasitic nematode burrowing nematode, Radopholus similis constitutes one of the major limiting factors for banana production causing extensive root damage resulting in serious economic losses. Survey was under taken to know the distribution of burrowing nematode, R. similis in banana growing districts of North Eastern Karnataka and revealed that the burrowing nematode, R. similis was inmaximum numbers both in soil and roots (4346 and 6437) followed by Helicotylenchus spp. (167 and 134) in all the four districts surveyed. However, the R. similis recorded the highest frequency of 100 per cent both in soil and roots. While the minimum of 58.33 per cent in soil and 43.7 per cent in roots for Helicotylenchus spp. growing districts of North Eastern Karnataka.
