Entomologists continue to find aphids in traps near seed potato fields in the region. University of Minnesota Extension entomologist Ian MacRae says the green stems and vines on the potatoes will attract aphids, increasing the risk of PVY virus. “There are some large populations in isolated areas for commercial potatoes,” says MacRae. “There’s some foxglove aphids and green peach aphids. These are important virus vectors for PVY into seed potatoes.”
