The efficacy of different extracts of neem leaf on seed borne fungi
Aspergillus
,
Rhizopus
and
chemical characterization of the neem leaf extracts were studied in vitro on the culture medium. The growth of both
the fungal species was inhibited significantly (p<0.01) and controlled with both alcoholic and water extract of all ages
and of the concentrations used. The alcoholic extracts of neem leaf was most effective in comparison to aqueous
extract for retarding the growth of
Rhizopus and
Aspergillus. The crude aqueous and alcoholic leaf extracts of neem
was more effective in inhibitions of growth of the fungi
Aspergillus in comparison to inhibitory effects on
Rhizopus
growth in the artificial culture medium. Leaf extracts of neem which are cheap and environmentally safe are
promising for protecting crop species against the fungal infestation and leading towards improvement of the crop in
terms of yield and productivity. @ JASEM
