19 - 1 August 2023

This week our hosts include Monique Rivera, assistant professor of entomology at Cornell AgriTech; Kerik Cox, associate professor of plant pathology; and Anna Wallis, fruit IPM coordinator.

In this episode, Monique talks about optimizing pesticide efficacy via managing pH, water quality, proper mixing, and application rates. Kerik tells us about how to spot and avoid fruit finish disorders including apple scarf. Anna brings us her State of the State on current growing conditions and pests around the state. Recorded July 31 and released August 3, 2023.
