Integration of herbicide and fertilization treatments as well as search for effective fungicide preparations are of a particular importance in plant disease control. The aim of this three-year experiment w to assess the effect of herbicide treatments and methods of nitrogen application on the occurrence of root and foot rot caused by Gaeumannomyces graminis, Fusarium spp., Oculimacula spp., Rhizoctonia spp., and to determine frequency of fungi infesting the stem base. The results have demonstrated that soil nitrogen fertilization limited symptoms of take-all but favoured more intensive presentation of sharp eyespot. The symptoms of cereal and grass eyespot as well as those of take-all became more visible when nitrogen was applied to the soil than on leaves. A mixture of the herbicides Chwastox 300 SL and Starane 250 EC was the most effective in controlling sharp eyespot, while soil and foliar application were the most effective in controlling take-all. Granstar 75 WG, applied separately or in combination with the herbicides Starane 250 EC and Chwastox 300 SL, resulted in more pronounced symptoms of sharp eyespot and take-all.
