Update for codling moth and oriental fruit moth at Winchester


As of today (June 20), 1423 degree days (DD) have accumulated since biofix for oriental fruit moth (OFM) at Winchester (April 14). OFM is now entering the second half of its second generation of the year. If captures in pheromone traps are exceeding the 10 moth/trap/week threshold, optimal timing to control this portion of second generation OFM in both peaches and apples is between 1450 and 1500 DD, which will occur between June 21 and June 23.

As of June 20, 913 DD have accumulated since codling moth (CM) biofix at Winchester (May 1). The next sprays for CM management would target second generation at the following timings: Rimon at 1250-1320 DD, Assail, Belay, CM virus, Esteem or Intrepid at 1350 DD, and all other products at 1450 DD. The NEWA website predicts 1054 DD for CM on June 26.

Until next time, best wishes.
