Abstract
Peanut seed samples collected from different localities in Ismailia a d EI-
SharKi8 governorate in Ihe two seasons. 1999 and 2000 showed that the percentages
of contamination with aflatoxin were 17% and 11.4% in the lsrnailia governorate, while
Ihe percentages In EI-Sharkia governorate were 18.4% and 4% in 1999~2000
seasons.
The highest percentages of seed contaminated with the yellow mold we,e
obtained from peanut samples presenting Ismallla (wesl Kantara locality) followed by
EI-ShClrkia gOllernorate (Belbles locality). 68.3%&48.5%in 1999 season. Seed
presenting Ihe 2000 season which Aeou- Hamaad (EI. Sharkia) and Faied (tsmailia)
localities recorded the mold aI43.6% and 37.3% respectively. The COll)mon
\so\a~ed pathogenic fungi from seeds in \he governorate was Aspergillus navus
followed by A. paras/ficus, while A. ochraceus was the lowest In this respect. The
highest rate of A. flavus frequency was showed in peanut seeds collected from
ismama followed by EI· Sharkla gOllemorate In the first season. while the opposite
results were obtained in the second season. Also. the frequency in A. navus presence
was higher in the seeds than obtained in the peanut sheUs of samples collected from
the gOllernorate in the two seasons.
The highest percentage and frequencies of A. flavus and A. parasiticus were
recorded in peanut samples contaminated with high level of ana toxins. Also. all
contaminant samples wilh aflatoxins were found infected wilh A. flavus andior A.
parasilicus. Data obtained here indicated that East Kantara and EI-korain in Ismailia
and EI·Sharilia governorate. respectlvely, were free from contamination with aflatoxins
in the two successive seasons of the investigation
