Potato problem...

Asked November 21, 2017, 11:32 AM EST

Planted some Russet eyes in the Spring and harvested a few several weeks ago, and all were fine. Left most in the ground until the past week, then harvested the remaining spuds and put them in a vegetable draw. Took them out to use for Thanksgiving, only to find them all with bored holes with dark trails throughout each spud. They had looked fine when I dug and washed them. Thanks for any help on this matter. Art Dietz

Thanks for your question! This sounds like wireworm damage and may be the result of extended time in the field after maturity. It is best to harvest potatoes about two weeks after vines die down.
