Nate Stacey, WSU Extension, Puyallup

Turf Management Strategies that Prevent and Control Pests, Weeds, and Diseases

Turfgrass IPM starts by answering the question, “Is turfgrass the appropriate plant material in this environment?” We’ll look at common pest, disease and weed problems, and show how cultural practices can prevent or control those problems in a variety of turf areas, from high-use, high maintenance turf to general park areas.



Steve Manning

Invasive Plant Control, Inc.


Practical Control Techniques for invasive plant species

Invasive species management must employ an integrated approach that includes both innovative and known techniques to be most successful. Steve will present environmentally and economically sound control strategies that can be readily used to meet goals and actions for weed management in the Pacific Northwest.


BREAK 15 min




10:05 – 11:00am

Clay Antieau, SPU

Science-based strategies to enhance resilience to soil-borne pests and diseases.

Wood chips have been commonly used as a mulch to suppress weed growth, but this is based on misconceptions and narrow understandings of the function of wood in and on soil. A more strategic use of wood chips in ecosystem restoration and ornamental landscapes remediates soil compaction, diversifies soil food webs, and support healthy plant growth. Diverse plant communities resist pests, diseases, and invasion from noxious weeds—resulting in reduced need for application of herbicides and other chemicals. Put wood chips to work!


Karen Peterson and Maria Winkler

Weeds on the Move: Preventing the Spread of Invasives

With the ever-increasing challenges with managing noxious weeds in urban areas, preventing the spread is the first step in effective control. Karen and Maria will talk about prevention strategies that work for the common invasive plants in our landscapes.

Nolan Rundquist, SDOT

The Top 5 Pests of Urban Street Trees in Seattle

Street trees health is difficult to achieve, given that urban vegetation is under constant stress from exposure to excess heat and injury. This scenario I provides an avenue for insect pests and diseases. Nolan will explain how Seattle Department of Transportation monitors these threats and how IPM strategies are implemented.


Chris Rippey, Seattle Parks

Identification, effects of and management strategies for the most problematic decay organisms found in Seattle Parks trees.

This presentation will cover how the Urban Forestry Unit of Seattle Parks manages an urban forest system with both natural areas and developed parklands. We often make tough choices in regards to trees with decay organisms. We know these organisms play a key role in forest regeneration and creating habitat and foraging space for wildlife while structurally compromising these trees. Before making the tough choice of removal or retaining a tree, we must know what we are dealing with. This talk I will introduce you to the five most problematic decay organisms that we find, what effects they have on trees and how we address those trees.



BREAK 15 min



10:05 -11am

Kevin Jensen, WSDA

Tales from a WSDA Inspector

Kevin will cover Investigations and inspections he has conducted, plus describe problems and the solutions when using pesticides. He will also cover the dos and don’ts of proper recordkeeping

11:00am -12:00pm

Becky McGuire, WSU

Managing pesticide Applications for Bystander Risk and Drift.

As a licensed pesticide applicator, you know how to read and follow the label and how to use your application equipment. But a successful application is not just following the label and using the equipment correctly. You need to be observant before, during and after a pesticide application to reduce the risk of bystander exposure. This presentation will examine bystander exposure incidents that have occurred in Washington. We will explore what caused the exposure and what can be done to prevent exposure in the future.


12 noon-1pm

WSDA credit scan and LUNCH




Larry Garcia and Barb DeCaro

The Latest Innovations in Rodent Control

Rodent control strategies and products are evolving toward better prevention of rodent invasions, better sanitation practices and away from use of highly poisonous baits. Learn about new IPM strategies that are working for large US cities and how we can employ these in Seattle and King County.
