Bowers, with funding from the Western Integrated Pest Management Center, is measuring the cold-hardiness of puncturevine-eating weevils from New Mexico to see if they can tolerate cool northern climes and potentially boost biocontrol efforts throughout the region.

Lessons Learned from 20 Years of Management of Invasive Knotweed on an Unregulated Western River
Presenters: Jill Silver, 10,000 Years Institute and Lauren Kuehne, Omnifishient Consulting
Description: Invasive knotweed was introduced into the Hoh River during a flood in 1999 and efforts to manage it began shortly thereafter. Those efforts were well documented with extensive data collection, and this presentation looks at some of the lessons learned during the 20-year effort.

Integrated and Cooperative Russian Thistle Management in the Semi-Arid Pacific Northwest
Presenter: Judit Barroso, Oregon State University
Description: This presentation will focus on Russian thistle ecology (seed germination, seed viability, seed longevity) and the amount of water extracted from the soil if it is not controlled; Russian thistle control post-harvest and some ideas to improve the control at that time; and whether cooperative management is helping to reduce Russian thistle infestation and its control cost.

Use of Precision Applied Steam to Control Soilborne Pathogens and Weeds in Lettuce
Presenter: Mark Siemens, Department of Biosystems Engineering, University of Arizona
Lettuce drop (Sclerotinia spp.) and in-row weed control are major concerns of California and Arizona lettuce growers. Soil disinfection using steam is a highly effective technique for controlling plant pathogens and weeds, but is cost prohibitive since conventionally steam is applied to the entire soil profile. To address this, a prototype band-steam was developed where only narrow strips of soil centered on the seed line are treated. The device is principally comprised of a 35 BHP steam generator mounted on a bed shaper. The system's design and operation, as well as field trials results will be presented and discussed.
Developing Non-chemical Harvest Weed Seed Control Strategies in Dryland Crops
Presenter: Eric Westra, Department of Agricultural Biology, Colorado State University
Talk will cover updates on field trials evaluating how chaff lining fits into dryland cropping systems in the Central Great Plains as an integrated weed management tool. Evaluation of chaff lining weed control efficacy in wheat, corn, and grain sorghum will provide information on how this integrated weed management tactic will fit in new geographic regions.

Topic: Spot It! Report It! Remove It! Mobilizing Residents in the Fight Against Invasive Weeds
Presenter: Qiting Chen, IPM Coordinator, City of Edmonton, Alberta
Description: Public education and awareness of invasive plant species are essential to support integrated pest management efforts in municipalities. The public plays an important role in detection, data collection and early intervention of invasive plant species. In Edmonton, efforts to engage the public in IPM activities have been ongoing and in 2019 the city launched a social marketing campaign called Spot it, Report it, Remove it. Tactics used include public outreach events, community weed pulls, door-to-door outreach campaigns, and the weed identification feature in the Edmonton 311 app. We will discuss the results and lessons learnt from the campaign.

Revegetating Weed-Infested Rangeland
Presenter: Jane Mangold, Montana State University
Seeding desired vegetation to compete with weeds is sometimes necessary when weeds have
dominated rangeland for many years and remnant vegetation is scarce. This presentation will share research results from a variety of Montana studies where seeding was integrated with other weed-control strategies.

Ecological Management of Kochia in Irrigated Western Cropping Systems
Presenter: Prashant Jha, Associate Professor and Extension Weed Specialist, Iowa State University
Description: This presentation will highlight on how to best implement sustainable integrated weed management programs to reduce herbicide reliance and manage weed resistance to herbicides in sugar beet-based crop rotations of the Western United States.
