The Weed Science Society of America and five affiliated scientific societies have announced plans for upcoming annual meetings that will spotlight new innovations and best practices in weed control.

Each of the events will be conducted virtually. First up are the annual meetings of the Canadian, North Central and Northeastern weed science societies.  Details are below, along with “save the date” information for additional events.

Canadian Weed Science Society, Nov. 23-27, 2020

This year’s CWSS annual meeting will focus on the past, present and future of weeds and invasive plants.  Plenary speakers include: Jacques Cayouette, Owen Olfert and Meghan Vankosky of Agriculture and Agri-Food Canada; Claude Lavoie of Laval University; Toni DiTommaso of Cornell University; Ruojing Wang of the Canadian Food Inspection Agency; Marie-Josée Côté of the Ottawa Plant Laboratory; and Clarence Swanton, professor emeritus at the University of Guelph and a former CWSS president.

The many topics on the agenda include:

  • Use of meta barcoding to find weeds and invasive species in seed lots

  • Forage, rangeland, forestry and industrial vegetation management

  • A proactive approach to managing multiple herbicide resistant waterhemp

  • Robotic weeding for vegetable crops

  • Using electricity for weed control

There will be live-streamed content throughout the week, including question and answer sessions, awards presentations, a general business meeting and social events.  All presentations will be prerecorded and available for at least a month after the meeting.  Certified crop advisor (CCA) credits will be available for attendance in select sessions.

Conference registration is now available online.  The $150 Canadian fee ($25 for students) includes a year’s membership in CWSS.  Further details are available at

North Central Weed Science Society, Nov. 30-Dec. 2, 2020

The upcoming 75th annual meeting of NCWSS will kick off with a general session on the past, present and future of weed science.  Two special symposia are planned during the event, including:

  • How extension services are being adapted to limit direction interactions during the COVID-19 pandemic; and

  • Innovations in equipment and application methods, including nozzles, wind tunnels, spatial modelling, UAVs, See ‘n Spray and other technologies.

More than 160 prerecorded oral and poster presentations will be offered on a wide range of topics – from resistant weeds and riparian buffer strips to advances in “Harperian” ecology.  Each oral presentation will be followed by a live question and answer period.

Other activities include a popular session on what’s new in industry, a weed science “Quiz Bowl,” awards presentations, a gathering of women in weed science, virtual tours of member facilities for graduate students, and chatrooms for networking.

Northeastern Weed Science Society, Jan. 4-7, 2021

NEWSS will host its annual meeting as part of the Sixth Annual Northeastern Plant, Pest and Soils Conference with the Northern Region of American Society of Horticultural Science and the Northeast Branch of the Tri-Societies.  Theme for the meeting is “Opportunities for Mutual Learning: Pests and Pandemics.”

Breakouts will feature agronomic crops; fruit, vegetable and tree crops; turf and ornamentals; and vegetation management/restoration.  Each will include prerecorded research presentations, with a corresponding live Q&A session, topical keynote and roundtable discussions. In lieu of student poster presentations, prerecorded “lightning talks” will feature two-minute research overviews, with a corresponding live Q&A.

Live content will include a general session featuring keynote speaker Laura Meyerson of the University of Rhode Island, oral competition presentations by students, a social networking event, and business meetings with awards presentations.

All content, whether prerecorded or live, will be available for on-demand viewing for one year after the meeting. For more information, visit
