We are conducting a survey of uncontrolled weeds in winter wheat and early-seeded spring wheat (or durum) fields in Saskatchewan. Please contact me if you are interested in participating or learning more.

OK trying to get back on track after a busy few weeks - here's your #WeedIDWednesday! I love finding this one, it's so small and delicate!

Trying to get an idea of where kochia has spread to in the Prairies. If you've got kochia, especially a newer problem, we'd love if you would upload your observation to iNaturalist so we can get a feel just how far it's moved! Please retweet! Project here: inaturalist.org/projects/kochi…

🌿 Aquatic plants in irrigation canals may seem harmless, but unchecked growth can block water flow, damage infrastructure, & reduce water delivery to farms. 🚜 Keeping canals clear protects our #foodsupply and agricultural economy. #WAPMS

🌾 4-year study in #Saskatchewan is targeting herbicide-resistant #Palmeramaranth & #Waterhemp through early detection, cultural control & outreach. Farmers can send pigweed samples for genetic testing—$4K/yr in support available. 🔗 bit.ly/3VxJkRa #WSWS #weedscience

Wildfire risk is high in the West for 2025: record heat, early snowmelt, invasive grasses booming after a wet winter - PLUS federal staffing cuts in USA. Weeds fuel fires. Managing them is critical to protecting lives, land & ecosystems. #WSWS #WildfireRisk #WeedScience

🎯 Size matters when managing #waterhemp! Effective foliar herbicides work best when this weed is 3 inches or smaller. 🚨 Wait too long, and control drops fast. With heat and moisture, waterhemp takes off quickly! ⚠️ I know, easier said than done. This spring/summer has been

#Cheatgrass is challenging to control in #drylandwheat due to widespread #herbicideresistance, and cause #winterwheat yield losses of up to 92%. Oregon State University shares how cultural practices at seeding time might help on #weedersofthewest. smallgrains.wsu.edu/weeders-of-the… #downybrome

My grad student, Renan Favera, is doing a great job advancing our understanding of bristly hawksbeard (Crepis setosa) biology and management in white clover. I look forward to his contributions. Stay tuned.

📅 The 2026 WSWS Annual Meeting is headed to Tucson, AZ — March 2–5, 2026 at the Tucson Marriott University Park. Join us for in-depth discussions on #weeds, #invasiveplants, & integrated management strategies tailored to #weedscience in western North America. #WSWS #WSWS2026

Always great to see more outreach resources highlighting the importance of preventing and managing #invasiveplants. Nothing new for us in #weedscience - but critical for raising public awareness and protecting ecosystems! 🌱 nytimes.com/2025/07/02/rea… #WSSA #weedmanagement #weeds

🔥 Important reminder from the Western Society of Weed Science: Fireworks, drought, and weeds are a dangerous combo. Dry vegetation can fuel #wildfires - especially this time of year. #WSWS #firesafety #weedscience #invasiveplants #drought #wildfireprevention #fireworks
