Abstract

The present study aimed to investigate the effects of some essential oils on inhibiting fungal growth of A. flavus and aflatoxin production. Clove oil was found as the best among six different oils tested against the radial growth at the concentration of 0.05 mL/100 ml. However, other oils were also significantly better than the control except the pumpkin oil. Although pumpkin oil was slightly effective than the control at its higher concentration (0.05 ml per 100 ml), but it was not effective at its lower concentrations (0.00, 0.01 and 0.03 ml/100 ml). All tested oils were significantly better than the control in suppression of mycelia growth and highest suppression was accomplished by clove oil at 0.05 ml/100 ml concentration, while, pumpkin oil was not effective. Although pumpkin oil was slightly better than the control at its higher concentration (0.05 ml/100 ml), it was not effective at its lower concentration (0.00, 0.01 and 0.03 ml/100 ml). Spore germination was also affected by the oils tested. Clove oil gave complete inhibition at its higher concentration followed by Cummin, Rehan, Garlic and Desert date, while Pumpkin oil was the least one. Aflatoxin production was highly affected by the essential oils tested. Clove and Cummin exhibited a complete inhibition followed by Rehan, Garlic and Desert date while Pumpkin oil was not effective.
