The codling moth biofix dates for this season are June 10 for early regions and June 14 for late regions determined by Erika Bent, APM.
Suzanne Blatt, AAFC, has run Jeff Franklin's calculations for the degree day model today according to the current forecast to predict when degree day thresholds will be met for treatments. The models were run today with a degree day threshold of 10 degrees (C) using Kentville weather station data.
