Side effect of two herbicides (iodosulfuron-methyl/Na + mefenpyr-diethyl = Husar and isoproturon = Tolkan) on micromycetes on winter wheat was study. Herbicide treatment reduced the whole number of fungi and number of genera in phyllosphere. It reduced number of the rhizosphere fungal genera, too. Population of Chrysosporium sp. markedly increased after Husar application, whereas population of Trichoderma harzianum was markedly reduced. Tested herbicides inhibited the development of Fusarium avenaceum on wheat leaves. Iodosulfuron-methyl/Na + mefenpyr-diethyl significantly reduced the growth of F. avenaceum in vitro.Keywords:
