Abstract


Ten plant extracts obtained from differ-ent plant parts were evaluated against sorghum leaf blight pathogen Exserohilum turcicum for determining their efficacy. Among the tested ex-tracts, garlic was found most effective in sub-stantially suppressing the radial growth of the pathogen by 60.77%, followed by jatropha (59.66%), neem (52.22%), tulsi (50.00%) and bael (49.66%) under in vitro conditions. With three sprays garlic, neem and jatropha reduced disease severity by 46.36, 43.38 and 41.01% respectively in glasshouse. Garlic also appeared best in re-ducing disease severity by 26.80% under field conditions with three sprays. Increased number of sprays resulted in improved reduction in dis-ease severity.
