Abstract:
Leaf blight (Alternaria triticina) is major disease in irrigated areas of MP. Given the significance of wheat leaf blight, a field investigation was done employing various fungicides and plant extracts to study their comparative efficacy in controlling foliar blight and yield of wheat in the field. Seven different solo fungicides viz. Propiconazole, Pyraclostoribin, Azoxystrobin, Difenoconazole, Propineb, Thiophanate methyl, Trifloxystrobin and seven different combinations fungicides viz, Luna (Fluopyran + Tebuconazole), Sofia (Hexaconazole + Carbendazim), Azoxy super (Azoxystrobin + Tebuconazole), Azoxy top (Azoxystrobin + Difenoconazole), Vitavex power (Carboxin + Thiaram), Nativo (Tebuconazole + Trifloxystrobin) were evaluated as a foliar spray under field conditions,, Propiconazole @ 1 ml/L and combination of Tebuconazole + Trifloxystrobin @ 1 g/L was found most effective against Alternaria leaf blight. Further, thirteen solo and combination plant extracts viz. Garlic, Neem, Ashwagandha, Datura, Ginger, Tulsi, Giloy and Ginger + Garlic, Tulsi + Garlic, Neem + Ashwagandha, Ashwagandha + Garlic, Ginger + Neem, Neem + Tusli along with control were evaluated at the rate of 5% against Alternaria triticina. Garlic clove extract @ 50 gram/L and combination of Ginger + Garlic@ 25 gram/L + 25 gram / L was found most effective against Alternaria blight under in-vivo condition.
