Spud Scoop, September 12, 2020

Welcome to Spud Scoop for the week ending on September 12, 2020. No late blight has been reported in ND, MN and MB. This week no late blight spores were found in the spore traps. Aphid vectors were down at all locations this week with cooler temperatures slowing down reproduction and movement. With multiple nights of freezing temperatures, potato vines in many areas have died. Because of this we will be ending the spore trapping network and this newsletter for this growing season. The cooler temperatures have provided favorable harvest conditions. Ideal tuber pulp temperature for harvest is 45 to 65 F. Yesterday was 9/11, and as Dr. Ian MacRae said “let’s take a moment to remember those brave individuals who run towards danger in order to safeguard us all.” Have a happy and safe harvest!
