Observations on the occurrence of foot and root rot diseases were conducted in 2006–2009, on commercial plantations of winter triticale. Disease index and percent of infected plants were calculated. Root rot was recorded in the highest intensity, followed by eyespot and Fusarium foot rot, in lower. Significant differences in the occurrence of root rot and eyespot, were stated in particular years. A previous crop significantly affected the occurrence of root rot and eyespot. The lowest intensity of diseases occurrence after legume were recorded, and the highest after winter cereals and root crops. The intensity of root rot was also higher after maize. The lowest occurrence of eyespot was observed after a fungicide treatment at the start of stem elongation. No significant effect of cultivar factor on the intensity of disease occurrence was shown. Studied factors did not affect stem base infection by Fusarium spp.
