Zusammenfassung:	The polyphagous pathogen Sclerotinia sclerotiorum causes significant diseases of sunflower and oilseed rape while Diaporthe wilt, invoked by the pathogen Diaporthe (Phomopsis) helianthi, is another important disease of sunflower in Slovakia. Since 2001 we have identified S. sclerotiorum on Iva xanthiifolia 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.
