Chickpea wilt caused by Fusarium oxysporum f. sp. ciceris (FOC) is one of the most prevalent and damaging diseases in chickpea-growing areas. To manage FOC in an environmentally friendly and sustainable manner, the current studies were carried out in 2023 and 2024, and emulsion-based bioformulations of two potential Trichoderma isolates, T. harzianum AMUTH-1 and T. viride AMUTV-1 were prepared and tested under field conditions. For comparison, Pseudomonas fluorescens AMUPF-1, Grow-Power™ (commercial bioagent) and fungicide (carbendazim) were used as benchmarks. Field studies have shown that chickpea variety RVG-202 was highly susceptible to FOC and developed severe wilt at the vegetative stage. However, application of the emulsion-based bioformulation of T. harzianum significantly reduced the wilt severity (55%) and enhanced the plant growth and yield of chickpea by 23-33% and 31%, respectively. The effect of this emulsion formulation was also at par with fungicide, carbendazim and commercial bioagent, Grow-Power™. Hence, T. harzianum emulsion bioformulation may be considered as an alternative control measure for multi-pathogenic diseases of chickpea plants. This outcome could also be used to devise a suitable integrated management module to safeguard chickpea plants from the FOC.
