Silver Scurf of Potato

Silver Scurf of Potato

Silver scurf is a surface blemish caused by the fungus Helminthosporium solani.  In addition to affecting the appearance of the tuber, the lesions on the tuber skin result in increased moisture loss in storage. 

How do you prevent your tubers from looking like the one in this photo? These suggestions were given at the Storage Workshop on Disease Control at the 2013 Idaho Potato Conference held in Pocatello, ID on January 23, 2013.
