When treating trees and shrubs for insects, mites, or diseases, applicators must be precise in their timing so that control can be established. We commonly use growing degree days to predict vulnerable stages of insects, mites, and diseases but with our climate shifting, growing degree days are not always a reliable source. What if a more predictable way to time treatments, such as plant growth stages, existed? Plant phenology uses cyclical biological events based on climatic conditions (bud swell, leaf development, flowering, fall color, etc) to coincide with insect, mite, and disease vulnerability. This session will explore the benefits of adding plant phenology to your treatment program so that you can reduce pest resurgence from the use of broad spectrum pesticides and deliver a more predictable outcome for your clients.
