In this week's regular episode, we hear from Kerik about the basics of fire blight management in blossoms, and scab and blight forecasting. Anna brings us the State of the State update on degree day accumulation and phenology. This week for the entomology update we have a bonus episode on pollinators with Monique and Dr. Scott McArt, so be sure to check that out!

This week we're joined by Dr. Julianna Wilson, Assistant Professor of entomology at Michigan State University. In this episode, Monique brings us some brief entomology updates, and then talks with Julianna about mating disruption for San Jose scale. Kerik continues with apple scab and fire blight forecasts, as well as a bonus fire blight seasonal outlook. Finally, Anna brings us the State of the State phenological and pest updates from around the state.
