Popis: Monitoring of Puccinia graminis subsp. graminicola and Puccinia coronata f. sp. lolii was carried out in Plant breeding station called Větrov. The pathogens were estimated on turf grass (Lolium perenne L., Deschampsia caespitosa (L.) P. B.) from 2009 to 2014. Puccinia graminis subsp. graminicola was detected in the increased level in 2009 and 2012. The highest amount of mixed infections was determined in 2014 because of the warmest winter from all monitored years and low precipitations. Significant differences were found out in the resistance of similar plant materials grown in different fields. Significant effect of weather conditions and supposed effect of different infectious pressure on various fields were reflected in these facts. At evaluated grasses, the highest (P < 0.05) occurence of Puccinia graminis subsp. graminicola. Lolium perenne L. was observed and the infection of Puccinia graminis subsp. graminicola (P < 0.05) was determined higher than in Deschampsia caespitosa (L.) P. B.
