A Recent Study: Effect of Neem Leaf Extract and Neem Oil on Penicillium Growth, Sporulation, Morphology and Ochratoxin A Production

September 2, 2020 BIOLOGY 0

In vitro trials were conducted to evaluate the effect of Azadirachta indica (neem) extracts on mycelial

growth, sporulation, morphology and ochratoxin A production by P. verrucosum and P.

brevicompactum. Azadirachta indica A. Juss (Meliaceae) (neem plant) extract is one of the most

important plant products which inhibit mycotoxin production. The effect of neem oil extract from seeds

and leaf was evaluated at 0.125, 0.25 and 0.5% and 6.25 and 12.5 mg/mL, respectively, in Yeast

Extract Sucrose (YES) medium. Ochratoxin A production was evaluated by a thin-layer

chromatography technique. Oil extracts exhibited significant (p ≤ 0.05) reduction of growth and

sporulation of the fungi. No inhibition of ochratoxin A production was observed. Given its accessibility

and low cost, neem oil could be implemented as part of a sustainable integrated pest management

strategy for plant disease, as it has been shown to be fungitoxic by inhibition of growth and

sporulation. Evidences from the current and other studies shows that fungal species react differently

to compounds from the neem tree.
