Abstract
Effect of Puccinia spp. and application of chemical control on seed yield components and seeds germination capacity of perennial ryegrass was investigated. Field trials were carried out over two seasons evaluating triazole fungicides applied one or three time. The weather condition were favoured for rust development in both years of the experiment. The rust disease symptoms were observed only during the first year. It was possible to observe a big effect of rust disease and application of chemical control on seed yield components and seeds germination capacity.
