Flight Seasonalities of Main Fruit Pests During the Growing Season56 min - Season 7, Episode 4 - April Freeze
Don is joined by Kari and Shan this week to discuss what happens what a spring freeze doesn’t just “nip” buds. Shan highlights what to do after the frost: how to sample across a block, cut buds to spot real freeze damage in the reproductive tissue.
Kari gives an early fire blight heads-up as warm weather accelerates bloom, plus a smart “minimal spray program” mindset for blocks that lost fruit to winter injury.Frost Protection Strategies: https://extension.psu.edu/frost-critical-temperatures-and-frost-protection
