Spud Scoop August 14, 2020

Hi and welcome to Spud Scoop! Late blight was confirmed in Wisconsin and genotyped as US-23. No late blight spores were found in the traps this week. Aphid numbers took an even bigger jump this week with the vector numbers and the PVY Vector Risk Index tripling over last week. A number of efficient vectors were found at most locations, including Green Peach Aphids being recovered from both the Crookston and Hoople traps.
