Abstract

Sclerotinia sclerotiorum is soil-inhabiting and considered one of the most devastating plant pathogens causing stem rot in chickpea. To develop an effective management strategy for the disease, various bio-agents and fungicides were evaluated against the pathogen.   Trichoderma viride showed superiority among the various bio-agents evaluated in vitro against S. sclerotiorum. Out of 5 fungicides evaluated against S. sclerotiorum and T. viride, iprodion caused 100% growth inhibition for the both, while carboxin was less inhibitory to T. viride than S. sclerotiorum. Therefore, carboxin was selected for seed treatment and iprodion for foliar spray in combination with T. viride based bio-formulation. A combination of soil application formulation Pusa Biopellet 4G (T. viride), seed treatment with Pusa 5SD (T. viride) + carboxin + Mesorhizobium ciceri and foliar spray with iprodion at 40 days after sowing provided the highest disease reduction and enhanced the plant health attributing parameters such as seed germination, shoot and root lengths and number of pods plant-1. Pusa Biopellet 4G and Pusa 5SD individually were also found effective in reducing disease incidence and improving plant health, but their combined application was found superior to the use of any of these formulations alone for all the variables.
