Hi all, I ordered some potatoes from a reputable company, and these potatoes were planted in 2 totally separate gardens (mine and my parents). I just dug up a few of the earliest ones, and they are awesome. Unfortunately when my parents dug up their potatoes they were covered in worms or maggots (??). They tried growing potatoes several years ago in a garden bed adjacent, but not connected to the one they used this year, and the same thing happened. I'm not sure what these are, and why they appeared in their garden and not mine. They were burrowing right into the potatoes themselves, and causing quite a bit of damage. Does anyone know anything about what these might be, and how to prevent them if possible? P.S. We are in Northern Ontario, zone 3b/4a. Our potatoes were planted within a week of each other (mid June), and had sprouted nicely and looked healthy at the time of planting. I've attached a couple of pictures: Thank you!
