Efficacy of fungicides against Exserohilum turcicum (Pass.) Leonard and Suggs causing turcicum leaf blight of sorghum

Abstract

Efficacy of different non-systemic, systemic and combi-fungicides against Exserohilum turcicum the fungus causing turcicum leaf blight of sorghum was done employing poison food technique. The results revealed that, among the six non-systemic fungicides, mancozeb at all the concentrations gave the 100 per cent inhibition of mycelial growth. Among the seven different systemic fungicides studied, maximum inhibition of mycelial growth of 96.29, 98.44 and 98.52 per cent was noticed in Propiconazole at0.05, 0.10 and 0.15 per cent concentrations. Among the six combi-fungicides tricyclozole + mancozeb and trifloxystrobin + tebuconazole at all the concentration showed hundred per cent inhibition of mycelial growth.
