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: May 24, 2013
May 24, 2013The first treatment to control codling moth is needed early during the week of May 27th (around 250 DD50, 5 percent CM egg hatch on May 27th). If hand applied mating disruption materials (Isomate® or CheckMate® products) are planned for the control of CM, Oriental Fruit Moth (OFM), dogwood borer, peach tree borer and lesser peach tree borer, the dispensers should be already placed in the orchards. First generation Oriental fruit moth flight is winding down across the state. Plum curculio (PC) adults will need to be controlled for at least another week. Brown marmorated stink bug (BMSB) is continuing its movement away from overwintering shelters and feeding on multiple species of plants, most likely not inside orchards. All pheromone traps for monitoring fruit insect pests should already be placed in orchards.
