Pigeonpea is one of the important pulse crop of Madhya Pradesh, a State of India. The plant gets infected by the pathogen Fusarium udum causing wilt disease, which is one of the major constraints in the production and productivity of pigeonpea. The present study aimed to carry out in vitro condition to assess the possible use of biocontrol consortia in field conditions. Six Trichoderma consortia viz., T1- T. viride + T. harzianum (JC-I), T2- T. viride + T. virens (JC-2), T3:- T. harzianum +T. virens (JC-3), T4- T. hamatum +T. viride (JC-4), T5- T. hamatum + T. harzianum (JC-5), T6- T. hamatum + T. virens (JC-6) and T0- Control were evaluated for their antagonistic activity against F. udumunder in vitro conditions. The consortia of T4- T. hamatum +T. viride (JC-4) was found most effective(58.82 %) in inhibiting the radial growth of Fusarium udum. The volatile compound from consortium of T5-T. hamatum + T. harzianum (JC-5) exhibited maximum growth inhibition (81.84%) and sporulation of Fusarium udum followed by T1-T. viride + T. harzianum (JC-I) (55.49% inhibition) . The culture filtrate of consortia of T4- T. hamatum +T. viride (JC-4) showed 100% inhibition of test pathogen followed by T5-T. hamatum + T. harzianum (JC-5) (82.89%) at 5 % concentration. It was also observed that with an increase in the concentration of culture filtrates of all the Trichoderma species, the radial mycelial growth of the test pathogen was proportionally decreased. The Trichodema consortium viz., T4- T. hamatum +T. viride (JC-4) may be tried in the field to manage wilt of pigeonpea because they worked synergistically and gave the high impact of their use.
