On this week’s episode of scaffolds, Monique talks to Dr. Tracy Leskey, an entomologist at USDA ARS and the director of USDA’s Appalachian Fruit Research Station and we are also joined by Dr. Laura Nixon, a postdoctoral researcher in her laboratory working on apple pest management. Kerik lets us know about the potential for powdery mildew and other disease updates, and Anna gives us our weekly state of the state update on trap captures and degree day accumulations.

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.
Segments recorded April 21 (Kerik), April 22 (Monique) and April 23 (Anna), and released April 23.
