Based on our degree-day model, Sparganothis fruitworm has accumulated 867 degree-days (DD) as of June 18, using April 15 as the biofix date. This indicates that flight activity has reached the 25% mark. We anticipate that peak flight will likely occur by the end of this week. This model uses averages across several beds, so there may be slight differences depending on the variety. We will continue to provide updates as the season progresses.
