When the potatoes have been harvested, graded and put into storage a great weight has been lifted. The spuds aren’t going to be stuck in the ground due to late season rain. Grubs and bugs aren’t going to start affecting the tubers, and it looks like most of the disease issues have been avoided. They’re safe. Except there is another consideration, and that is storage diseases.

Storage diseases discussed in Issue 12 of PotatoLink magazine includes:

  • Soft rot (Pectobacterium spp., Dickeya spp.)

  • Pink rot (Phytophthora erythroseptica or P. cryptogea)

  • Gangrene (Phoma exigua var. foveata)

  • Black dot (Colletotrichum coccodes)

  • Silver Scurf (Helminthosporium solani)

  • Pythium leak or Leak rot (Pythium spp.)

  • Fusarium dry rot (Fusarium spp.)
