As of June 23, Sparganothis fruitworm has accumulated 1,225 degree-days (DD) since the April 15 biofix, based on our degree-day model. This suggests that flight activity has surpassed 90%, with peak flight likely occurring around June 19, 2025. The model reflects average conditions across multiple beds, so some variation may occur depending on the variety. We will continue to provide updates as the season progresses. If needed, an insecticide application is recommended two weeks after peak trap catches—around July 3.
