We're back with a new look and sound for Season 2 of Scaffolds! If you've been following along, welcome back. And if you're new here, Scaffolds is a a weekly roundup of the timely updates on insect and disease management as well as phenological developments across New York State for apple growers.

We also have a new co-host, Dr. Kelsey Tobin, postdoctoral researcher in the Rivera Lab. Kelsey will take over for Anna Wallis, bringing us phenological, degree day, and pest event updates. Don't fret, Anna will still join us from time to time to share her expertise and news from around the state.

In this episode, we talk about what to expect and how to manage risk after a mild winter and warm temperatures in February and March. Monique talks about scouting and action thresholds for European red mites, and when to apply dormant oils. Kerik shares how to select a biofix, reducing early season inoculum, and the current apple scab forecast. Anna tells us about some exciting statewide scouting initiatives and events this season. Lastly, Kelsey brings us current degree day and phenology around the state.

All segments recorded March 25 and published March 26, 2024.
