Abstract
Isolation and Identification of the fungi Cladosporium herbarum associated with the date palm leaf spot disease in Basrah was carried out. And the results of the pathegenicity test showed the ability of the fangi C. herbarum to cause the infection and gave symptoms of the leaf spot disease on the tested leaves. And the study showed the activity of the disinfectants phenole, iodine, cetrimide and Hypochlorite against the fungi C. herbarum phenole showed high activity in the inhibition of the fungi growth at the concentrations 1.25% , 2.5% and 5% while iodine showed killing of all isolates at the concentrations 2.5% and 5% , however at the concentration 1.25% six cells staied alive after passing one minte And Hypochlorite showed killing at all isolates at the concentrations 2.5% and 5% and however at the concentration 1.25% ten cells staied alive after passing one minute And two cells staied alive after passing two and half minute and one cell alive after passing five minute. And cetrimide showed killing of all isolates at the concentration 2.5% and 5% , however at the concentration twenty cells staied alive after passing one minute and seven cells staied alive after passing two and half minute and three cells staied alive after passing five minute.
