    Description

    Cronartium flaccidum is a serious pathogen of twoneedle pines, especially of Pinus sylvestris, in northern Fennoscandia (Samils et al. 2010). The rust spreads via a number of alternate hosts in natural forests and gardens, among which species in genera Melampyrum, Pedicularis, Vincetoxicum, and Paeonia are the most important known ones (Gäumann 1959; Kaitera et al. 1999). In northern Europe, the most important species is Melampyrum sylvaticum (Kaitera et al. 2005), while in southern Europe the respective species is Vincetoxicum hirundinaria (Gäumann 1959). Cronartium ribicola is a common pathogen on fiveneedle pines in arboretums, botanical gardens, and parks in northern Europe (Gäumann 1959; Kaitera et al. 2013). The rust spreads mainly via Ribes (Kaitera and Nuorteva 2006).
