Abstract:
This study was conducted in the poisoning laboratories affiliated to the College of Agriculture and Forestry / University of Mosul for the year 2021 AD, where the study focused on knowing the effect of two types of extracts, first: the extract of red cabbage, the second: fenugreek seed extract, on the growth of each of the fungi Aspergillus flavus, A. ochraceus and Fusarium graminearum in a solid medium using concentrations of 25, 50 and 100 μl/treatment and in a liquid medium using concentrations of 125, 250 and 500 μl/treatment and compared with the standard treatment free of the extract, the treatments were incubated for 5, 7 and 10 days at a temperature of 28° C. The results showed that the addition of red cabbage and fenugreek extracts in all the concentrations used caused a significant decrease (P≤ 0.05) in each of A. flavus, A. ochraceus and F. graminearum, the inhibition rates ranged from 9.88-21.18% and 36.83-69.50% for A. flavus using red cabbage extract in solid and liquid media, respectively, and 7.79 – 17.99% and 27.88-65.03% by using fenugreek extract in solid and liquid media, respectively, while for A. ochraceus, the inhibition percentages by using red cabbage extract in solid and liquid media ranged 11.15-24.05% and 41.78-74.69% and by using fenugreek extract 9.02-19.11 and 36.97-68.13% for both mediums, respectively. The percentages of inhibition of F. graminearum using red cabbage extract ranged from 12.28-24.14% to 44.52-81.26% in solid and liquid media, and 10.84-20.94% and 31.01-71.30% were inhibited by using fenugreek extract. For both mediums, respectively, the lowest inhibitory concentration (MIC) of A. flavus occurred when red cabbage extract was added at 400 μl, which was higher than the minimum inhibitory concentration of A. ochraceus and F. graminearum, which was lower than the concentration used of fenugreek extract.
Key words: Red cabbage extract, Fenugreek extract, A. flavus, A. ochraceus, F. graminearum, MIC.
