This week on Scaffolds, I talk to Shianne Linsday, a graduate student in Dr Scott McArt’s lab, about our cool weather’s impact on pollinators, Kerik talks about getting through extended/multiple apple scab infection periods, and the lack of fire blight risk in a cold early bloom, and Anna gives us our state of the state update on trap captures and degree day accumulation around the state.

This week on Scaffolds, I give some reminders to think about as the season starts, Kerik talks scab predictions, and Anna gives us our weekly state of the state update on degree day accumulations around the state. Kerik: Apple Scab Disease forecast predictions for New York as of 4-12-26: There’s a lot of variability for Apple Scab risk across the regions. Eastern NY and the capital district have an easy week with few wetting periods and low levels of ejection. The lake champlain region may not all be at green tip. Western NY and the fingerlakes have accelerated apple scab maturity and prolonged wetting periods that span the week with high risk. In this region, the average temperatures during wetting periods are low 60s and could lead to many infections.
