Welcome to Scaffolds Podcast, a weekly roundup of the timely updates on insect and disease management as well as phenological developments across New York State for apple growers.


This week we are joined by Monique Rivera, assistant professor of entomology at Cornell AgriTech; Kerik Cox, associate professor of plant pathology; Līga Astra Kalniņa, Cox Lab graduate student; and Anna Wallis, Fruit IPM Coordinator.


In this episode, Monique talks about future directions in IPM and the function of peptides. Kerik and Līga warn of a major fireblight infection event and overview general fireblight management strategies, and Anna brings us the latest phenology and pest captures from around the state.
