Abstract
The study included isolation and identification of Fusarium Species from three soil types by dilutions plate method and plant debris in soil , the soil location were desert soil beside Najaf - Karbala road , Alkufa riverside soil and Hurriya rice field .The soil samples and plant debries were taken from half of July ,October 2009 and January and April 2010 . In this study 13 species of Fusarium were isolated , the study showed that the following species : F.konzum , F.circinatum , F.phyllophilum , F.pseudonygamai , F.beomiforme , F.hostae , F.dlamini , F.lateritium F.nelsonii and F.denticulatum . were recorded as first time in Iraq . The results revealed that the high frequency 6.6 % of the Fusarium species was in desert soil during the summer season . F.konzum was isolated 100 % frequency from the desert soil in July 2009 compared with other species . The pathogenecity tests to radish seeds on P.D.A. showed that the F.beomiforme killed all the tested seeds while seed germination in F.hostae and F.semitectum treatments were 94.67 and 92 % respectively . F.lateritium non significantly decreased the Shoot length (12.2 mm) of radish compared with control treatment (12.4 mm) while the F.nelsonii (isolate B) incrased the shoot length (12.63mm) compared with control that rate (12.oo mm) . F.denticulatum produced Aflatoxins while the other species gave negative result .
