Abstract:
Of late, the incidence of wilt of mungbean caused by Fusarium oxysporum has increased substantially in the mungbean growing areas of Madhya Pradesh. In vitro studies were conducted to evaluate the efficacy of seven different fungicides viz., Azoxystrobin, Propineb, Thiophanate Methyl, Difenoconazole, Mancozeb, Mancozeb+Thiophanate methyl, Boscolid+Pyraclostrobin and locally available plants viz., Allium cepa, Allium sativum, Azadirachta indica, Parthenium hysterophorus, Polyalthia longifolia, Ricinus communis and Withania somnifera against Fusarium oxysporum. Mancozeb+Thiophanate methyl (0.15%), was the best fungicide which completely inhibited the growth and sporulation of the fungus, followed by Propineb, Mancozeb, Boscolid+Pyraclostrobin, Difenaconazole. Parthenium leaf extract was found best in inhibiting the growth and sporulation of F. oxysporum as it produced 78.3 percent growth inhibition of F. oxysporum at 15 percent concentration followed by castor leaf extract (69.4 percent growth inhibition).
