In order to evaluate the effectiveness of biocontrol agents, organic amendments and chemicals against Heterodera cajani infecting pigeonpea, an experiment was conducted on farmer's field in Bharuch district of Gujarat (India) during three successive seasons (2007–08 to 2009–10). Results revealed that combined application of T. harzianum (5 kg/ha) + P. chlamydosporia @ 20 kg/ha or individual application of both the nematophagous fungi in furrows at the time of sowing of pigeonpea effectively and economically suppressed the population of cyst nematode, H. cajani. The treatment of P. chlamydosporia registered maximum (1:15.36) ICBR followed by T. harzianum (1:14.05) and combine application of T. harzianum + P. chlamydosporia (1:10.98).
