Bin Piles Are a Source of CM Off the Normal Model

Sunday July 01, 2018 12:00am
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.

Weather Data Makes DAS Run

Wednesday June 20, 2018 4:28pm
Around-the-clock and accurate weather data are at the core of DAS. But when they are missing, DAS cannot make model predictions. While insect and plant development models are less prone to disruption, disease models cannot run without the necessary weather input.

Monitoring Codling Moth Damage

Thursday June 14, 2018 9:42am
Monitoring codling moth at the end of each generation gives a good indication of the success of your management program and where in the orchard damage occurs. The sampling protocol for the Taiwan protocol can give you good accuracy and is simple to implement. Banding trees can serve as monitoring and control technique.

Which Type of Apple Sunburn is in Your Orchard?

Wednesday June 06, 2018 12:00am
Sunburn browning is the most prevalent type of sunburn, and is caused by high fruit surface temperatures (FST) and ultraviolet radiation. The FST required to induce sunburn browning varies by cultivar, but is in the range of 113 to 120 °F (45 to 49 °C).
