What Do Washing Dishes and Sanitation for Plant Production Have in Common?

Room B113

Speaker: George Grant, GGSPro Technical Specialist Supervisor, Griffin Greenhouse Supplies

Regardless of your standard operating procedures, sanitation is a key factor in having a successful season. Very few management practices have the duality of being preventative, curative, and cost-effective whereas a strong pre-season and mid-season sanitation plan does. For this reason, we strongly focus on maintaining clean production spaces, inputs, and equipment to manage a wide variety of plant-related issues. Surprisingly, there are scenarios we run into in our daily lives that overlap with plant production such as washing dirty dishes. We will use these common scenarios to help demonstrate the cultural and chemical steps necessary for effective sanitation.

Biopesticides: The Ideal Team Players in Plant Health Programs with a Focus on Biofungicides

Room B113

Speaker: Michael Brownbridge, Ph.D., Biological Program Manager, Plant Diseases, BioWorks Inc.

In North America, moves to adopt more biological inputs in plant production are driven by issues with pesticide resistance, market trends and restrictive re-entry intervals. This is where biopesticides can help. Their unique modes of action bring value in resistance management. The fact that they are derived from natural sources makes them more acceptable to consumers, and their safety means they can be applied with minimal disruption to day-to-day crop management activities. Yet there are still many misconceptions around what biopesticides are, their efficacy, and where and how they can be used. This presentation focuses on the use of biofungicides and their effective positioning in plant health programs.

Flathead Borers in Nursery and Orchards

Room B113

Speaker: Melissa Scherr, Ph.D., Research Associate, Nursery Crops, Oregon State University Extension

Flathead borers can be serious pests of nursery trees and tree nut and fruit crops in the Pacific Northwest. In particular, two flathead borers in the genus Chrysobothris — C. femorata (flatheaded apple tree borer) and C. mali (Pacific flatheaded borer) — contribute damage in many different deciduous trees and shrubs grown commercially, weakening or even killing trees by girdling the trunk or branches. A third species, C. nixa, attacks cedar and juniper nursery trees. The flatheaded apple tree borer is a common pest in the Eastern and Central United States, while the Pacific flatheaded borer and flatheaded cedar borer are only found west of the Rockies. The Pacific Northwest region is home to all three species.
