The brown rust of couch grass (Puccinia persistens var. persistens) in Bohemia hibernates on Agropyron repens growing in regularly cut fodder plantations. Under suitable climatic conditions (warm temperatures and precipitation), the inoculum spreads rapidly. Transfer to wheat cultivars Triticum aestivum cv. Mironovská 808 and Little Club was confirmed by infection trials and differences in urediospore wall thickness.
