The studies were carried out to find out the combined effect of root knot nematode, Meloidogyne javanica and wilt pathogen, Fusarium udum in ten wilt resistant/tolerant accessions of pigeonpea. Presence of M. javanica with, F. udum increased wilting from 8 to 33% in KPL 44, 15 to 60% in AWR 74/15, 25 to 50% in ICP 8859 and ICPL 89049 and 15 to 50% in ICP 12745, whereas in other five accessions wilting did not increase much in presence of nematodes. The plant height, fresh shoot and root weight and dry shoot and root weight were significantly lower in combined inoculation of nematode and fungus compared to nematode or fungus alone. The root knot index varied from 3.00 to 4.50 in these accessions in both treatments having nematode alone and nematode and fungus together. The lowest root knot index was observed in KPL 43 (1.50) and GPS 33 (1.75).
