“…Similar results were also observed in studies by [21] where they evaluated "effects of different culture media on S. rolfsii mycelial growth, sclerotial production". [22] examined "total of seven media were used for studying the growth of S. rolfsii in Lentil" and [23,24] also proved "the efficiency of PDA in enhancing mycelial growth of fungus out of nine different cultural media. Their results reported that potato-dextrose medium was most suitable for mycelial growth and sclerotia production of S. rolfsii.…”

Collar rot stands as a significant affliction of chickpea, attributed to the pathogen Sclerotium rolfsii. The current research investigated the morphological and cultural diversity among 10 isolates of S. rolfsii collected from major chickpea cultivation regions of Karnataka by assessing their growth rate, colony color and appearance, and features of Sclerotium including color, arrangement, and maturity days of Sclerotia were recored on two different media. The isolates BSR 2, BSR 5, BRS 9 and BSR 10 exhibited notably rapid growth on both Potato Dextrose Agar (PDA) and Corn meal Agar (CMA). Overall, the growth of these isolates appeared denser, indicating more substantial mycelial formation on PDA compared to CMA. These findings underscore the existence of variability among the isolates. In vitro evaluation of fungicides for the management of collar rot was evaluated using new combi fungicides. Among those Carbendazim 12% + Mancozeb 63% (0.15%), Hexaconazole 4% WP + Zineb 68%, Carboxin 37.5% + Thiram 37.5 %, Tricyclazole18 % + Mancozeb 62% WP, Captan 70% + Hexaconazole 5% WP at 0.05 per cent concentration showed cent per cent inhibition. Hence, these combi fungicides have been proven effective in suppressing the pathogen, making them valuable tools for implementing successful disease management strategies during the initial stages of crop growth.
