Win Cowgill is an emeritus Rutgers Professor who currently owns his own consulting company called Win Enterprises where he consults on horticulture and pomology. And consults from New Jersey up to Maine. Kerik continues to talk about getting through extended/multiple apple scab infection periods, and the lack of fire blight risk in a cold bloom. This week on Scaffolds, I talk to Win Cowgill an emeritus Rutgers professor about what is going on in the north east region with all of the freezes and some options for what to do if you have damage in both apple and peach, Kerik gives us an update on scab and fire blight management strategy, and Anna closes the episode with the state of the state update on phenology, degree days, and trap captures around the state.  LInk from Win Cowgill MSU Critical Spring Temperatures for Tree Fruit Bud Development Stages https://www.canr.msu.edu/fruit/uploads/files/TreeFruitCriticalTemperatures.pdf Historical Phenology and Average Degree Day Accumulation Base 43 (for reference) -            Tight cluster (McIntosh) || 228 ± 27 || 27-Apr ± 7 days -            Pink (McIntosh) || 289 ± 26 || 3-May ± 7 days -            Full bloom (McIntosh) || 378 ± 35 || 10-May ± 6 days -            Petal fall (McIntosh) || 479 ± 42 || 18-May ± 6 days   Phenology & DDs for NY NEWA Stations from 1/1 – 5/4 Station || Stage || DD 43F || DD 43 Forecast Through 5/10 || Geneva (AgriTech North) || Early Bloom || 460 || 476 Highland (HVRL) || Petal Fall || 524 || 616 Clifton Park || Bloom || 421 || 494 Peru (Forrence) || Open Cluster || 284 || 346 Medina (Roberts) - Inland || Early Bloom || 420 || 464 Appleton North - Lake || Early Bloom || 310 || 346 Fairville (The Apple Shed) - Inland || Early Bloom || 447 || 491 Williamson (DeMarree) - Lake  || Early Bloom || 375 || 404 *all DDs Baskerville-Emin, B.E Upcoming Pest Events Pest/Phenology Event || DD Base 43˚F || Approx.
