Abstract: Pest control is one of the important challenges of the agriculture and food commodity. The contamination of pistachio with a flatoxin produced by Aspergillus flavus is the main problem in the export of this product in recent years. Aspergillus flavus is one of the fungus which has a wide range of hosting in seed, air and soilalong within animal foods. In the present research, the effect of aqueous extracts of zataria (Zataria multiflora Boiss) and peppermint (Mentha piperita L.) aerial parts were examined against A. flavus isolated from contaminated pistachio using agar dilution method. The extracts with concentration of 100-600 ppm were added to Potato Dextrose Agar (PDA) medium and all tests were done at least in triplicate. In order to eliminate the effect of osmotic potential of the extracts, Poly Ethylene Glycol (PEG) was used with similar osmosis pressure. The fungus growth diameter were calculated and expressed as mean±Standard Deviation (SD).
