Storage Scald of Apples

Sunday August 12, 2018 12:00am
The appearance of storage scald has been related to orchard temperature during the final weeks of fruit maturation. DAS provides accumulated hours below 50°F as well as orchard management recommendations for this postharvest disorder.

Predicting Third Generation of CM

Wednesday August 01, 2018 12:00am
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.

NEW Model: Fruit Growth

Thursday July 26, 2018 8:38am
The range of fruit sizes at harvest can now be predicted well before harvest with the new fruit growth model. The current model makes predictions for Gala, Red Delicious, and Cripps Pink.

Stinkbugs Seek Orchard When Shrubs Dry

Saturday July 21, 2018 12:00am
Adult stinkbugs puncture fruit with their beaks to feed on the fruit flesh. Stinkbug damage in apples can occur beginning in mid-summer and accumulate through the harvest period when new adults move into the orchard from outside habitats.

Taiwan Protocol and Export Required Sampling

Saturday July 14, 2018 12:01am
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.
