Abstract:
In vitro efficacy of various isolates of bio-agents against wilt of bottle gourd revealed that the isolate Trichoderma viride (Sardarkrushinagar) was the most effective against Fusarium oxysporum and it was followed by T. harzianum (Junagadh), viride (Junagadh), T. viride (Navsari), Bacillus subtilis (Sardarkrushinagar) and Pseudomonas fluorescens (Sardarkrushinagar). Among ten phyto - extracts evaluated, the maximum growth inhibition of F. oxysporum was recorded with neem extract (52.38%) and it was followed by nilgiri extract (41.62%). Among four oil cakes and three organic manures evaluated, the maximum inhibition of F. oxysporum was observed with neem cake (98.75%) and it was followed by poultry manure, castor cake, farm yard manure, cotton cake and vermicompost under In vitro condition.
