Abstract:

An experiment was conducted to evaluate the effect of five plant extracts, one bio agents and one fungicide in in vitro and in vivo againstleaf spot of maize caused by Curvularia lunata.  Mancozeb @ 0.25% was effective in the inhibition of mycelial growth (69.35%) of C.lunata. Among the bio-agents, Trichoderma viride was found effective in the inhibition of mycelial growth (50.77%). Among the plant extracts, neem leaf extract @ 10% was found effective in the inhibition of mycelial growth  (42.84%) followed by eucalyptus leaf extract @ 10% (40.66%), bael leaf extract  @ 10% (37.45%), tulsi leaf extract (34.82) and onion bulb extract (31.80). The plant extracts, potential bio agent and fungicide found effective in in vitro were tested against the curvularia leaf spot of maize under field conditions during kharif 2017-2018. Among all the treatments, mancozeb @ 0.25% was found effective in the disease reduction (35.85%), followed by Trichoderma viride @ 2% (49.12%). Amoung the plant extracts, neem @ 10% was found effective in disease reduction (45.70%) followed by eucalyptus @ 10% with (45.94%),  bael leaf exract @ 10% (47.39%), tulsi leaf extract (48.64%), and onion bulb extract (49.55%).
