Abstract:
A laboratory experiment was conducted to study the efficacy of seven botanicals against Aspergillus niger, Aspergillus flavus and Fusarium oxysporum f. sp. cepae which are associated with post-harvest bulb rot of onion using poisoned food technique in vitro (each @ 10%). Among the botanicals garlic (71.11%) showed the highest mycelial growth inhibition. This was followed by ghaneri (70.37%) and tulsi (8.52%) was found less effective with minimum mycelial growth inhibition against A. niger. However, Garlic (69.26%) showed the highest mycelial growth inhibition. This was followed by Neem (61.85%) and tulsi (9.63%) was found less effective with minimum mycelial growth inhibition against A. flavus. Among the botanicals evaluated aginst F. oxysporum f. sp. cepae, Onion (60.37%) showed the highest mycelial growth inhibition. This was followed by Garlic (51.11%), Eucalyptus (47.04%) and Ginger (32.59%) was found less effective with minimum mycelial growth inhibition respectively.
