The 1996-1999 research investigated the health status of stem base of winter wheat cultivated after spring cereals in pure stand, their mixtures and mixtures with pea. The forecrop showed the greatest impact on the plant infection with Gaeumannomyces graminis, followed by Fusarium spp. The lowest number of plants infected by G. graminis was observed after oats and oats with pea. Infection by Fusarium spp. was the lowest after oats with barley, however the highest after triticale. The pathogens occurring on stem base were represented mostly by Fusarium spp., especially F. avenaceum.
