Crop Protection and Cultural Considerations When Propagating

Room B113

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

Propagation is a balance between maintaining an environment conducive to young plant production while managing a myriad of insect and disease pests that also thrive in these conditions. We will walk through various cultural, chemical, and biological inputs useful when propagating to ensure an efficiently and cleanly grown product. Strategies discussed during this presentation include moisture management, biological and conventional pesticides for below and above ground pests, cleaning up material using plant dips, sanitation steps, use of plant root stimulants and more!

A Milkweed Contamination Study Spotlights Pollinator-Safe Growing – An Oregon Nursery Shows the Way

Room B113

Co-Presenters:
Sharon Selvaggio, Pesticide Program Specialist, Xerces Society for Invertebrate Conservation
Sam Bidwell, Integrated Pest Manager, Log House Plants; Founder, Sunnyside Sam’s Wholesale

People across the country are working to help restore monarch butterflies by planting milkweed. A recent study showed that milkweed plants purchased from garden centers across the country contained a wide variety of pesticide residues, putting monarchs at risk. In this seminar, we invite a thoughtful conversation about how nurseries can use practices that result in pollinator-safe plants. We will present the findings and implications of the milkweed study and share examples of how a local nursery, Log House Plants, puts pollinator-safe growing into practice.

What it Takes To Build A Robust IPM Program & Resistance Management

Room B113

Speaker: Brock Martindale, National Nursery & Greenhouse Strategic Account Manger, Corteva

Broch will cover the importance of building a robust IMP program and how you can avoid building resistance in your facility. You are bound to find several things that you can take back to your facility to improve your process. Broch will cover the 7 steps to success and a deep dive into preventing resistance.

Phytophthora Root Rot – Understanding a Complex Problem

Room B113

Speaker: Dr. Jerry Weiland, Research Plant Pathologist, USDA-Agricultural Research Service

Phytophthora root rot has been a persistent problem in the nursery industry for almost 100 years. Yet, despite decades of research, there has been little progress in improving control of this disease. This session will explain why root rot has become more difficult to control over time and will cover the latest research on pathogen biology and fungicide management. Case studies will be used to illustrate the consequences of nursery production decisions on overall disease control and management recommendations will be provided.

Defining and Building Your Culture to Create a Thriving Team (SPANISH ONLY)

Room B119

Speaker: Elizabeth Peña, Value Stream Leader, Peoria Gardens Inc.

A culture is how you solve problems and how you behave toward others. You must strike a balance between knowledge and behaviors, between head and heart. If you want your team to thrive, you must first define your culture, then do the important work of building your culture into everything you do together. You are invited to learn how Peoria Gardens, a second-generation greenhouse in Albany, Oregon, defined their culture, then built that culture into a business that continues to be recognized as one of the best places to work in the horticulture industry.

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.
