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: https://t.co/eI1vLQPi3u @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%).

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. https://t.co/nfFa7cS60v

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. https://t.co/4Kzn0Ngrc7

Learn from @VTTurfweeds, Ph.D., as he provides both chemical and cultural control strategies for Poa annua. #PBIGordonTurf #GCSAA https://t.co/LMMWFaSlKp

Andrew Osburn confirming Poa annua cross resistance to pronamide and prodiamine in Florida and Texas populations at @SouthWeedSciSoc.

[Shawn Askew, Ph.D. @VTTurfweeds]

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: https://t.co/RP201PD2mm
