Late-Season Management of Black Dot and Silver Scurf in Wisconsin Potatoes

As the potato harvest season advances, late-season tuber diseases are of concern. Two diseases in particular—black dot (Colletotrichum coccodes) and silver scurf (Helminthosporium solani)—can diminish tuber quality, reduce storability, and lead to post-harvest losses. Managing these diseases requires careful attention in the late season, as cultural and harvest practices can influence disease.
