Flight Seasonalities of Main Fruit Pests During the Growing Season

Don, Kari, Greg, and Shan walk through the overnight freeze and the chain reaction it triggers across fruit set, disease risk, and insect timing in our orchards. We share what to scout first, what to spray only when it makes sense, and how to protect pollinators while the weather keeps changing.

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.
