Abstract:

Early blight disease of tomato caused by Alternaria solani (Ellis) is an economically important disease causing huge losses throughout Country. In the present investigation six fungicides viz. Trifloxystrobin 25% w/w + Tebuconazole 50%WG, Difenconazole 25% EC, Hexaconazole 5 % SC, Propineb 70 WP, Azoxystrobin 23%SC, Thiafluzamide 24%SC at 50, 100, 250, 500 and 1000ppm concentration and Six plants extracts viz. Datura stramonium (Dhatura) green fruit extract, Azadirachta indica (Neem) seed kernel extract, Allium sativum (Garlic) bulb extract, Eucalyptus spp. (Eucalyptus) dry leaf extract, Crotalaria juncea (Sunhemp) seed extract, Euphorbia hirta (Bara Dudhi) whole plant extract at 1, 2, 3, 4 and 5 percent concentration were tested against A. solani under laboratory condition. Among the six fungicides, most effective fungicides was found Hexaconazole 5% EC which exhibited 100.00 percent inhibition in mycelium growth at 100ppm followed by followed by Thiafluzamide 24% SC and Trifloxystrobin 25% w/w + Tebuconazole 50% WG at 500ppm. Out of six plant extracts tested against A. solani in vitro, most effective plant extract was found Allium sativum @ 5% which exhibited maximum inhibition in mycelium growth (45.15%) followed by Crotalaria juncea @ 5% (44.40%), while minimum inhibition in mycelium growth was recorded in Euphorbia hirta.
