| Abstract | ||
| The experiment was carried in the laboratory of pestcides and mycotoxin. In Dept. Plant Protection. College of Agriculture, University of Baghdad during 2006. The aim of the study was to test the effect of Fylax and Urea and powder of Cinnamon bark and powder of the peels and leaves of sour orange for inhibition Aspergillus ochraceus and detoxification of Ochratoxin A.and to powder of Cinnamon bark and powder the peels and leaves of sour orange in the inhibition of growth Aspergillus flavus and preven of production of Aflatoxin B1 in media. Results of the isolation and idenitification showed that brofler chicks were accompanied with several fungi Aspergillus spp,Penicillium spp, Fusariums, ssp, Rhizopus spp, Mucor spp., Cladosporium spp. In percentage reached 37%, 34%,20%,7%, 1% and 1% respectively,The most dominanate fungus was A. ochraceus which reached 8%.Thin Layer chromatography (TLC) showed that about 35% of A. ochraceus isolates produced Ochratoxin A on isolated from brofler chicks, and some grain. The number of isolates produced this toxin were (7) from (20) isolates. The results revealed that the addition of Urea or Fylax to PDA (Potato Dextrose Agar) had caused 100% inhibition the growth of fungus growth and sporolation when concentration of 5%, 0.2% was used. Cinnamon bark powder at concentration of 5% has caused inhibition around 95% to both A. ochraceus and A. flavus. However , the peels and leaves powder of sour orange at 5% concentration have caused 49.5% and 45.6% inhibition to both A. ochraceus and A. flavus respectively | ||
