10/10/11

'Tis almost the season -- again -- and most people are just beginning to think about gift lists and travel arrangements. But for Christmas tree farmers like Gordon Repine of Scotia, Pa., the holidays last all year. One thing many growers do to prepare is attend the Christmas Tree Management Short Course offered by Penn State's College of Agricultural Sciences. Thanks in part to Penn State's assistance, Repine "went from having 2,000 trees here to 20,000 trees," he says. Penn State for PA (PSU4PA) tells the stories of Pennsylvania residents whose businesses, communities and lives have been transformed by Penn State teaching, research and service.

Under the direction of Cathy Thomas, Pennsylvania Integrated Pest Management (IPM) coordinator, the project will focus on scale pests from Asia such as Elongate hemlock scale and Cryptomeria scale that cause a lot of damage to hemlock and fir trees. "Scale pests attack Fraser, canaan and balsam firs, all of which are important Christmas tree varieties in Pennsylvania," said Thomas.

In a paper to be published later this month in the journal Ecological Applications, the team's results indicate the best strategies for managing the destructive pests.
