The purpose of this research was to assess the functional value of the Super Trawnik lawn mixture. The studies were carried out between 2017 and 2019 at the Experimental Station of the University of Agriculture in Krakow (50 degrees 07 ' N, 20 degrees 05 ' E), and the experimental factor was the AGRO-SORB(R) Folium, a biostimulant containing amino acids and applied at three doses: 1, 2, and 3 L center dot ha(-1). Lawn visual quality was assessed on a 9-point scale, with 10-11 mowings at 4 cm during the growing period. An increase in the concentration of the stimulant applied as a spray resulted in a significant increase in its effectiveness; plants in plots with the highest dose of amino acid solution (Variant III) had the highest aesthetic and functional values. The AGRO-SORB(R) Folium reduced the occurrence of fungal diseases; compared to control plants, there was a 16% reduction of Fusarium patch (Microdochium nivale) infection and a 20% reduction of Dreschlera leaf spot (Drechslera siccans). Satisfactory effects were also recorded on plots where the product was applied at a dose of 2 L center dot ha(-1) (Variant II). Those plots had more favourably rated turf, with higher resistance of plants to Fusarium patch by 12% and to Dreschlera leaf spot by 20% compared to control.
