The final installment of our @UTturfgrass video series on #PoaAnnua control is now live. In this video, we explore strategies for control in overseeded ryegrass. Check it out @TnTurfAssoc @TennesseeGCSA @TVSFMA @utextension @UTAgResearch youtu.be/r9ANwyaqrHQ

Our @TAMUWeedNinjas PhD student Bholuram Gurjar @gurjar_bho24226 trained a YOLO model to recognize Poa in bermuda turf. Still needs some more improvement, but looks promising! @txresearch @ResistPoa @tamusoilcrop

Annual bluegrass possesses both an annual and perennial lifecycle at the same time. Learn more: bit.ly/3IG6vnl @GCSAA

That’s a wrap for Poa herbicide trials in North Texas! Some PRE+POST combos provided >120 days of >90% control…
Best treats included a SU herbicide (Katana or Tribute) + a PRE (Specticle, Barricade, or Kerb) + simazine…one application on 5 Nov 2023

Lots of questions about #PoaAnnua control this time of year, often on UDB greens. Plenty of good treatments in this trial and some that haven't met the challenge. #PicOfTheMonth for February @UTturfgrass

2nd to last app in 2-yr study comparing spring v. fall v. both apps of @PoaCure & cumyluron. Thus far, fall apps are most important for either herbicide. Two timely apps/yr of PoaCure (1.2 oz) or cumyluron (3 or 6 oz) all that’s needed when initial Poa populations are low (<10%). – at Sacramento, CA

3 new annual bluegrass videos are live on our YouTube. Go check them out! One tests a popular anti-dandruff shampoo as a POST option. youtu.be/VFPWXaX2Kdw

Check out our video on late season POST Poa control. This includes 3 different carrier rates of Glufosinate and others. Must watch for those with Poa outbreaks this spring, wondering what to do. youtu.be/uzvwpUy2jYA

Learn from @VTTurfweeds, Ph.D., as he provides both chemical and cultural control strategies for Poa annua. #PBIGordonTurf #GCSAA pbigordonturf.com/webinar-ch…

Cryogenic treatments work, even on cold adapted weeds such as Poa. This is 6 days after treatment of liquid nitrogen at 10, 20, or 30 mls. With an engineered application system, I may be able to go lower than 10 mls.

Highlights from a recent @ResistPoa study (led by @dervin_env) regarding lawn care operator insights on contemporary challenges with weed management were featured in this month's @lawnlandscape. Read the L&L article here: shorturl.at/ehtQV

Congratulations to @jbunruh as this year's recipient of the GCSAA President's Award for Environmental Stewardship. The @FGCSA knows first hand how instrumental he has been in the development and expansion of Golf BMPs in FL and the country. @GCSAA gcmonline.com/headlines/gcsa…

Very proud of Andrew Osburn for presenting his research on Poa seed persistence at the @ASA_CSSA_SSSA annual meeting in Baltimore. Proud to be his co-advisor alongside @MBagavathiannan. – at Baltimore, MD
