The trial was designed to assess the influence of fungicidal treatment (seed treatment, seed treatment and fungicidal spraying) on barley yield, grain quality and malt quality of spring barley. The experiment was performed in 2008–2009 using three brewer’s cultivars of spring barley: Ryton, Scarlett and Blask. The barley plants were protected with three seed treatment preparations, which contained triadimenol + imazalil + fuberidazole, cyproconazole + fludioxonil, triticonazole + prochloraz and a fungicide for spraying application which contained propiconazole + fenpropidin. The level of leaf infection and retained green leaf area were also assessed, along with grain yield and determination of hectoliter weight and one thousand grain weight. Laboratory tests were performed to determine grain quality characteristics, protein content, germination energy and malt quality. The elements considered in malt quality determination include malt extract content, Kolbach index, diastatic power, wort viscosity and final attenuation. The value of each parameter was used to give a numerical score of overall grain malting quality according to Molina-Cano. In relation to the untreated plots, the plots receiving seed treatment that contained triadimenol + imazalil + fuberidazole combined with the application of a fungicides during vegetation provided significant control of fungal infection, caused the increase in yield and a noticeable, from the technological point of view, improvement in quality of grain and malt.
