Predicting Third Generation of CM

Saturday Aug 01, 2020

Predicting the extent of the third generation of codling moth (CM) is based on a statistical relationship of the degree-days historically found on 1 August and at the end of the season on 1 November. We update this prediction roughly every 10 days after 15 August because the DD prediction for 1 November gets more accurate as we get closer.

Those expecting to export apples to Taiwan need to have their training updated every two years and use the sampling protocols negotiated with Taiwan. Three Orchard and Field Bin Sampling Protocol training sessions are scheduled for August.

Bin Piles Are a Source of CM Off the Normal Model

Wednesday Jul 01, 2020

Bin piles placed in the orchard are often a source of codling moth. Larvae spin up in the bins in the fall and emerge when the bins are placed in the field. Because the bins in the center of a pile are insulated from temperature changes, adults emerge from bins at different times than predicted by the model.

Fire Blight Model Turned Off June 21 – August 20

Monday Jun 15, 2020

The Fire Blight (CougarBlight) model is a blossom infection model and intended for use during moderate temperatures (50-86°F) that usually occur during spring and early summer and when flowers are open. This blossom infection model attempts...
