Thanks for reaching out. The OSU Orchard Extension specialist, Nik Wiman, runs a list serve for commercial fruit tree growers. He collects data from area growers and monitors several traps on the OSU research station. Biofix date for our area was set at 4/29 for this year.

Here is some information, I also included a screenshot of the model output.

In the model interface, set your biofix and most relevant weather station. For a 4/29 biofix the first cover spray (250 Degree-Days) is predicted to be May 30.
