Abstract
Health status of winter wheat roots and thecomposition of wheat root fungi were studiedover 1996-1999 following the cultivation ofoats in a pure stand and mixed with otherplants as forecrops. The infection of wheatroots by >Gaeumannomyces graminis wasobserved to be largely dependent on the kind offorecrop; the best being oats in a pure stand,and then oats with pea or lupin mixtures. Inthe emergence and shooting phases, saprophyticfungi were dominant, while in the stage of harddough stage mainly pathogenic fungi, especially>G. graminis were common. The pathogenicfungi were mostly represented by >G.graminis and >Fusarium spp., while >Rhizoctonia spp. were much less frequent.The composition of the fungal communitydepended considerably on the forecrop anddevelopment phase of the plant. The kind offorecrop significantly affected the frequencyof infection by >G. graminis. The highestnumber of isolates was obtained from wheat rootsof crops grown after a mixture of oats andbarley.
