Abstract
This study was conducted from December through May (2010-2011), to study the contaminants inherent for irrigation water in the fields of college of Agriculture in University of Baghdad. Two hundred and eighty one fungal isolates were isolated from the wells, Abu Ghraib river and the sewage water in the collegel of Agriculture which belonging to 16 genera, 13 of them belong to fungi imperfacti and one to either of Zygomycetes and Oomycetes and one to the sterile fungus. The experimental results showed that Pythium, Aspergillus, Rhizoctonia, Rhizopus, Fusarium were found mostly throughout all the months. The months results were all most same In the Percentage rate of the frequency of fungi, its was (99.96 –100) fungaI Isolation with anaverge of 6.247-6.25 % and the following fungi were found: Pythium, Aspergillu,s Rhizoctonia, in the water of the source studied, while Penicillium and Diplococcium in the water taken from the wells near the Dean office and the central Library, the plastic houses and Abu Ghraib river. Alternaria and Fusarium were found in the water taken from the wells near the Dean office, the central Library and from Abu Ghraib river, while Candida fungi was found in water taken from central Library wells and Macrophoma fungus was found in the water taken from the well near the Dean office, while Cladosporium was found in the water taken from the wells near the Dean office, the central Library and also in the sewage water. The Rhizopus was found in the water taken from all the College wells except the well near the plastic houses. Ulocladium fungus was found in the water taken from the wells near the Dean office and the plastic houses and Abu Ghraib river, while Thielaviopsis was found in the water taken from the wells near the Dean office and Abu Ghraib river, while the sterile fungus was found in the water taken from the wells near the Dean office and the plastic houses. This study showed that using seeds trap wae the best method of fungi isolation more than the direct method of isolation and both of them get the following percentage of fungus 11.17 and 8.53 % respectively.
