There is lack of reports of silver scurf resistant potato cultivars. NO had been negatively correlated with silver scurf disease previously. Therefore, a direct adverse effect between silver scurf and NO is not likely to happen. The disease cycle of silver scurf can be divided in two phases (field and storage). Silver scurf on tubers can be reduced by the systemic broad-spectrum fungicide TBZ. Furthermore, the silver scurf causes water loss which makes it difficult to peel the tubers. However, "Cephalosporium" does not reduce silver scurf on previously infected potatoes. In harvest (mostly in summer), silver scurf symptoms are not too apparent. Silver scurf is a plant disease that is caused by the plant pathogen Helminthosporium solani.
