Abstract

In India, particularly in Madhya Pradesh (Jabalpur), the pea is a significant pulse crop. Pea crop suffers from many diseases caused by fungi from which wilt is reported as one of the emerging disease in last few year. Fungal and bacterial bioagents have been identified as one of the greatest alternatives that doesn't harm the environment for minimizing the use of chemicals. The majority of biocontrol agents used to combat a variety of root, shoot, and postharvest infections are Trichoderma spp. The idea of creating microbial consortia for bio-control is based on the observation that in their natural habitats, bioagents exist in communities that provide some advantages to plants. In this study, the ability of consortium of Trichoderma in dual culture as well as its volatile and non-volatile compounds were evaluated. In all tested consortium in dual culture T. virens + T. harzianum recorded maximum percent growth inhibition (JC-1, 69.83%). In volatile compounds Percent growth inhibition 86.80 % was recorded highest in T. viride + T. harzianum (JC-2, 76.51%) and Percent growth inhibition in non-volatile compound will increase as concentration of bioagents increases in highest concentration 100% growth inhibition was recorded in five consortiums of bioagents that was T. virens + T. harzianum (JC-1), T. viride + T. harzianum (JC-2), T. viride + T. virens (JC-3), T. asperellum + T. longibrachiatum (JC-6) and T. longibrachiatum+ T. Virens (JC-7). The in-vitro test was performed October-November 2021.

Conclusion

Trichoderma consortium in dual culture give best result in T. virens + T. harzianum (JC-1, 69.83%) in volatile compound T. viride + T. harzianum (JC-2, 76.51%) and in non-volatile compound all were found satisfactory and in highest concentration 100% growth inhibition was recorded in five consortiums of bioagents that was T. virens + T. harzianum (JC-1), T. viride + T. harzianum (JC-2), T. viride + T. virens (JC-3), T. asperellum + T. longibrachiatum (JC-6) and T. longibrachiatum + T. Virens (JC-7).
