Abstract
Isolation from diseased peanut seeds showed that Aspergillus flavus, A parasiticus and A. ochraceus were the most dominant fungi associated with tested seeds and the frequency of their occurrence were 63.5.27.4 and 7.9 % respectively.
Acetic acid vapors at 4.0 1-1111 caused complete inhibition for A flavus and A. parasiticus and, at 6.0 1-1111 for A ochraceus in vitro. In vivo , under natural infection ,acetic acid vapors at 150 1-1111 completely inhibit fungi associated with peanut seeds. High reduction in infected seeds was obtained with acetic acid vapor at 125 and 100 1-1111 ,which reduced the infection by 85.8 and 73.7 % respectively, as compared with untreated seeds. Moderate effect was obtained with concentration at 751-11/1 which reduced the natural infection by 61.9%. Peanut seeds were artificially inoculated individually with spore suspension ( ,.' spores/ml) of A flavus, A . parasiticus or A ochraceus, then stored for 7 days. Inoculated seeds were fumigated with different concentrations of acetic acid vapors, in fumigation chamber. Results indicate that acetic acid vapor at 40.0 1-111111 completely inhibit A. flavus and A. parasiticus infection of peanut seeds and at 50.01-1111 for Aochraceus. Higher reduction was obtained with acetic acid vapor at 30.0 1-1111 lit reduced the artificial infection more than 69.7% for all tested fungi as compared with unfumigated seeds. While acetic acid vapors at 20.01-1111 has moderate effect.
It can be suggested that acetic acid vapors might be safely used commercially for controlling storage fungi of peanut seeds ..
