One of the most harmful infections to chickpea plants, Sclerotinia sclerotiorum, causes stem rot and causes financial losses all over the world. Beneath the soil's surface, as sclerotia, the pathogen can live for a very long time alongside the detritus. As a result, the condition is extremely difficult to manage, has nearly no known treatments, and only a few types have been shown to be somewhat successful against the infection. Thus, the primary goal of the research is to investigate the effects of a variety of treatments, including Rhizobium leguminosarum + Pseudomonas fluorescens combination, Trichoderma viride, Saaf (Carbendazim 12%+ Mancozeb 63% WP), Vitavax Power (Carboxin 37.5%+ Thiram 37.5%), Hexaconazole, and Rhizobium leguminosarum

+ Pseudomonas fluorescens, to investigate their impact on S. sclerotiorum suppression. While maintaining sustainability, bioagents improve the soil's properties and productivity. Fungicides have been found to be effective when bio-agents are not able to control a disease. Therefore, in this investigation, both methods of treatment were used. The results of an experiment conducted in both in vitro and in vivo conditions showed that chemical treatment with Saaf fungicide and seed treatment with T. viride were highly efficient against S. sclerotiorum.
