10 - 11am: Resist Developing Herbicide Resistance

Speaker: Tim Miller, Extension Weed Scientist, Washington State University NWREC, Mount Vernon, WA.

We used to think that weeds just aren't capable of becoming resistant to herbicides. We now know that to be false—weeds are quite fast becoming resistant to even our most effective herbicides. In this talk, WSU's Tim Miller will discuss how herbicide resistance develops, what the scope of the problem is, and how to best combat herbicide resistant weed species.


11am - Noon: Bee-Friendly Noxious Weed Control

Speaker: Alison Halpern, Executive Secretary, Washington State Noxious Weed Control Board

Noxious weeds are detrimental to our native ecosystems and agriculture; however, many of them provide pollen and nectar for bees and other important pollinators. Don't despair – you can control those invasive, noxious weeds while still helping our crucial pollinators out. Learn how in this presentation.


1pm – 2pm: El Nino Update, and the rest of the Winter and Early Spring forecast!

Speaker: Phil Volker, President, ERF Company, inc. Water Management Group Inc.

The latest on the massive El Nino that developed last summer, 2015, and continued to build through the early Fall. We should be seeing the effects over the West and Southwest, and certainly here in the Pacific Northwest too. I will also look ahead at the remainder of the winter and early Spring. It will be interesting to see how this shifts and turns.


2pm – 3 pm: The Dark Side of Combination Fungicides

Speaker: Jay W. Pscheidt, Extension Plant Pathology Specialist and Professor of Botany and Plant Pathology, Oregon State University

Several new combination fungicides have been registered for the ornamental industry. Some of these fungicides contain two active ingredients but a few may have 3 or more. Many of the new ingredients are at high risk of encouraging the development of resistant fungal pathogens. These new combinations represent a challenge for sustained plant disease management. Ideas will be discussed on how to best deploy these materials.
