Abstract: The polyphagous pathogen Sclerotinia sclerotiorum (Lib) de Bary causes significant diseases of sunflower and oil-seed rape while Diaporthe wilt, invoked by the pathogen Diaporthe (Phomopsis) helianthi Munt-Cvet. et al., is another important disease of sunflower in Slovakia. Since 2001 we have identified S. sclerotiorum on Iva xanthiifolia Nutt. in three locations and the infestation of I. xanthiifolia by D. helianthi has been observed only in one location of western Slovakia. The infestation of I. xanthiifolia by Sclerotinia disease and by D. helianthi has been observed only after secondary ascospore infection in sunflower fields.
