In southern counties we have accumulated approximately 102 DD base 45 since the biofix set on 4/16. Based on the current forecast, insecticides for OFM control should be applied in 7-10 days. In northern counties, only 14 DD have accumulated since the biofix set on 4/22 so no applications for OFM will be needed for about 2 weeks.

Disease Alert for Tree Fruit: Fire Blight; Apple Scab
In southern counties there is a significant risk for fire blight from Thursday through the weekend for any Pear or Apple orchards with blossoms open. If your orchards are at risk apply antibiotics at the first opportunity. The forecast rain will also be the first significant scab infection for apples. Growers can personalize their risk by visiting the NEWA website. Enter your zip code and follow the links for fire blight and apple scab. You will be prompted to enter phenology information for your location. Using April 6th for 50% McIntosh green tip, the model indicates approximately 40% ascospore maturity on April 20th for South Harrison Township Gloucester County.
