The aim of this work is the accurate diagnosis of the Puccinia species of the selected turf grass species under field and laboratory conditions and evaluate influences on the intensity of occurrence. The laboratory tests will be recommended for the best stage of plants to artificial infection. The experiment was carried out in collaboration with SŠ Větrov. In the two-year follow-up (in 2011 and 2012) were at particular times of samples of infected plants, which were then evaluated microscopically. And at the same time experimental work was carried out in laboratory conditions (artificial infection) in plant material of the same origin and assessed degree assault with a precise diagnosis of the type of pathogen. Between 2011 and 2012, was higher occurence stem rust than crown rust.. From a total of 514 tests was stem rust in 379 cases, while crown rust in only 40 cases. In 95 samples was observed incidence of both simultaneously rust and mildew spores remaining plants were discovered. Greenhouse resistance tests were performed on younger plants (3 sheets) and older (6 sheets) in 16 variants, of which 4 were control. Infected leaves were spray uredispor with talc and injected with an aqueous suspension followed by looking drops and were then sealed under insulators at 23 ° C for 24 - 48 hours.
