Abstract

The anti-fungal activity of some chemicals, herbal compounds/spices and plants at different concentrations were evaluated against the toxin producing Aspergillus flavus and Aspergillus parasiticus growth. Among the chemicals screened, benzoic acid (0.1 – 0.5 %), propionic acid (0.1 – 0.5 %) and copper sulphate (0.2 – 0.5 %) showed complete inhibition of Aspergillus flavus growth. In case of the herbal compounds/spices, clove (0.5 %) and clove oil (0.5 %), while among the plants garlic (0.5 %) and onion (0.5 %) showed complete inhibition. All the samples were also screened against Aspergillus parasiticus growth. Among the chemicals screened, benzoic acid (0.2 - 0.5 %), copper sulphate (0.1 - 0.5 %) and propionic acid (0.2 - 0.5%) showed complete inhibition of growth. In herbal compounds/spices, clove and clove oil (0.5%), while among plants, garlic and onion (0.5 %) showed complete inhibition of growth. Thus some herbal compounds/spices and some chemicals as preservatives may successfully replace synthetic pesticides and provide an alternative method to protect our staple food from the toxic fungal contamination.
