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.  ____________________________________________________________________________________ Phenology & DDs for NY NEWA Stations from 1/1 - 5/27 Station || Stage || DD 43F Geneva || fruit sizing || 906 Highland (HVRL) || fruit sizing || 965 Clifton Park || fruit sizing || 844 Peru (Forrence) || fruit sizing || 704 Medina - Inland || fruit sizing || 889 Appleton North - Lake || fruit sizing || 770 Fairville (The Apple Shed) - Inland || fruit sizing || 841 Williamson (DeMarree) - Lake  || fruit sizing || 833 *all DDs Baskerville-Emin, B.E ____________________________________________________________________________________ Upcoming Pest Events Pest/Phenology Event || DD Base 43˚F || Approx.
