| Abstract | ||
| The study was coducted to evaluated to efficiency of control agents (bio–cidal Fluoramil) and chemical control agent ( Ridomil MZ–50) to control seed decay and damping–off of wheat seedlings caused by Pythium aphanidermatum . The study has shown that bio-cidal Fluoramil compltly inhibited the pathogenic fungus growth in culture P.D.A. medium(% 100).The same result was given when the chemical fungicide Ridomil MZ – 50 was mixed with culture medium P.D.A. The Biological experiment has shown the positiveness of bio–cidal Fluoramil in the control of Wheat crop infection by the fungus P. aphanidermatum, the increase of growth markers through increasing germination percentage to(89.7 %)and the decrease of post-emergence damping-off seedlings to (0.6%) compared with control treatment (pathogenic fungus only) which were (32.6%) and (24.9%) respectively. The markers growth has shown that the bio – cidel Fluoramil significantly effects the dry weight of shoot that reached (0.522) gm at same time these markers decreased to (0.05) gm in the control treatment (pathogenic fungus only) . | ||
