10:00 - 11:00 a.m.: Biological Cheat Sheet – To Boldly Go Beyond Neonics

Kathleen Baughman, IPM Manager, Iwasaki Bros. Nursery and Brian Spencer, President, Applied Bio-nomics Ltd.

In this hour, Kathleen Baughman and Brian Spencer will discuss 10 things you should know about biologicals that will improve your understanding of how and why they work and what you need to know about the pests. More and more commercial nursery and greenhouse growers are using, or deciding where and how, to use beneficial insects, and reduce or eliminate insecticides and miticides from their available tools for control. Concrete examples will be given and a higher level discussion will take place based on strategies that are working at nurseries in Oregon and across North America. Attendees will walk away with several ideas to reduce the costs of pest control and make it easier to manage the pests.

Ulrike Mengelberg, Outreach Manager, Energy Trust of Oregon

1 – 2 p.m.: The Current Status of Rose Rosette and Other Emerging Diseases Affecting Ornamentals

Luisa Santamaria, Ph.D., Assistant Professor, Extension Nursery Specialist in Plant Pathology, OSU – North Willamette Research & Extension Center 

New plant diseases caused by fungal, bacterial, and viral pathogens are constantly appearing in different areas of the United States. It is important for all members of the nursery industry to be informed and aware of the current situation with these emerging diseases. This presentation will focus on current developments in the symptoms, prevention, and management strategies of rose rosette disease. Also updates of other emerging diseases affecting ornamentals in landscape and greenhouse production such as downy mildew, boxwood blight, and other viral diseases will be discussed.

2 – 3 p.m.: Unleashing Monsters: Global Trade in Live Plants Inadvertently Puts U.S. Forests at High Risk 

Wyatt Williams, Ph.D., Invasive Species Specialist, Oregon Department of Forestry 

Ever since European explorers first arrived, more than 400 non-native insects and pathogens have been introduced to American forests. Some of these have turned into notorious invasive species, all but eliminating their hosts from the face of the planet. For example, chestnut blight arrived from Asia and decimated the once mighty American chestnut. All in all, invasives have caused irreversible ecological harm, resulting in billions of dollars in economic damage.

According to Wyatt Williams, an invasive species specialist with the Oregon Department of Forestry, the nursery trade is indirectly responsible for introducing nearly 70 percent of the most damaging of these exotic species. He will discuss the implications of global trade in live plants and the risk to forest resources of the Pacific Northwest. Most importantly, he will outline steps that the nursery and the forestry industries can take together to avoid introducing the next invasive species while at the same time maintaining production and profitability.
