Fruit Research & Extension Center
Fruit Research and Extension Center
The Fruit Research and Extension Center (FREC) in Biglerville is situated on 180 acres of fertile land in south-central Pennsylvania, in the heart of the major tree fruit production area of the state. In addition to providing site-specific conditions for research, the facility increases opportunities for growers, consultants, consumers, and students to observe experiments and to consult with scientists. Extension specialists apply experimental findings to local conditions, and, in turn, make suggestions to scientists about new research needs.
Weekly Insect Bytes for July 25, 2014 and Spotted Wing Drosophila Update
July 25, 2014While in most orchards the brown marmorated stink bug numbers are still very low, at some locations we spotted the first fruit injuries caused by this pest. Populations of spotted wing drosophila might be higher than in the past this season due to tart cherry blocks that were not harvested because of a light crop and their potential as reservoirs for SWD populations to build.
Necrotic Leaf Blotch Appearing on Apples and the Home Stretch for Controlling Diseases of Stone Fruit
July 25, 2014Management is discussed for controlling the physiological disorder necrotic leaf blotch, which is being reported throughout the area. Managing late season bacterial spot and rot diseases on stone fruit is also discussed. Disease infection periods to date for apple scab, fire blight, cedar apple rust and cherry leaf spot are included to help growers determine where control failures may have occurred this season.
Late Summer Management of Orchard Pests
July 25, 2014Second generation flights of tufted apple bud moth and obliquebanded leafroller are underway in South-Central PA orchards, and third generation Oriental fruit moth and second generation codling moth flights are beginning. During our weekly searches on various actual and potential BMSB hosts we are continuously finding all instars of brown marmorated stink bug.
