Abstract
Description
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
