Abstract:
Onion (Allium cepa L.) is one of the most widely used vegetable due to its flavouring and seasoning the underground vegetable, both at mature and immature bulb stage in tropical and sub tropical countries. The foliar blight complex of onion resulted due to combined infection of Alternaria porri and Stemphylium vesicarium. The investigation on the fungitoxic effects of widely utilized rhizome, clove, bulb, seed and leaf extracts of various plants belonging to different families against the combined radial growth of A. porri and S. vesicarium revealed that Ginger extract recorded 83.70 and 86.85% while, garlic extract resulted in 79.81 and 82.04% growth inhibition at 10 and 20% concentration, respectively. The in vitro efficacy of various isolates of bio-agents indicated that Trichoderma viride (Junagadh) was highly efficacious followed by T. harzianum (Junagadh), T. viride (Sardarkrushinagar), T. harzianum (Sardarkrushinagar), T. viride (Navsari), T. longibrachiatum, P. fluorescens and Bacillus subtilis.
