In vitro evaluation on inhibitory nature of some Neem formulations against plant pathogenic fungi.
Different Neem formulations derived from the Neem tree (Azadirachta indica) have been found to be potential fungicides against a broad spectrum of plant pathogenic fungi. Some Neem formulations viz. Achook (0.15% EC), Bioneem (0.03% EC), Nimbecidine (0.03% EC) and Neemark (0.03% EC) were examined against some plant pathogenic fungi such as (Fusarium oxysporum, Alternaria solani, Curvularia lunata, Helminthosporium sp. and Sclerotium rolfsii). Among these Achook (0.15% EC) was found to be more active in terms of Minimum Inhibition Concentration (MIC) value followed by Bioneem, Neemark and Nimbecidine. Remarkably, although all these formulations are oil based, Neem oil itself did not exhibit any fungicidal activity.
