Abstract:
Twenty plants were selected and harvested their root exudates to study their antifungal potency. The results of the study showed that root exudates had marked influence on mycelial growth, colony diameter and sclerotia formation of S. rolfsii. Neem root exudate had maximum inhibitory effect on mycelial growth of S. rolfsii (58.82 %). This was followed by mango and shatavari root exudates which showed 54.89 per cent inhibition in each. There were no sclerotia formation on neem, mango, shatavari, sorghum, coconut, periwinkle and parthenium root exudates even after 15 days of inoculation. However, datura (-1.95 %), tamarind (-0.98 %) root exudates showed minimum per cent inhibition over control with profuse amount of sclerotia formation. It means datura and tamarind root exudates stimulate growth of S. rolfsii. Among the total samples, five promising plant root exudates viz. Neem, Sorghum, Mango, Coconut, Shatavari were selected for evaluating effect on sclerotia germination in different conc. (at 10, 20 and 50%). At 10% and 20% concentration neem root exudates whereas at 50% concentration mango root exudate found effective against S. rolfsii.
