Installing bentgrass into this P. annua green to evaluate encroachment. One study has mat layer pH gradient from ~5.0 to 7.5. Large differences in P. annua quality across the gradient. 2nd study will evaluate pH, phosphorus and PGR programs. Supported by USGA Davis and Tri-State

One week after seeding KBG, which means these are P. annua seedlings. Mesotrione applied at seeding is controlling the broadleaf seedlings, but most of these Poa seedlings will survive. One mesotrione application is usually not enough where there is a strong seedbank.

Don't forget to include MSO with quinclorac. Smooth crabgrass control with Drive XLR8 at max rate (64 oz/A) 2 weeks after application in both photos. Right side has MSO at 1% v/v.

My group will be discussing goosegrass, kyllinga, bare ground weed management, and more. Hope to see you there!

I suspect we will see some Japanese stiltgrass emergence this week. But probably still some time before crabgrass emergence since things cooled off.

Brandon McNally (@McNally_Brandon) was recognized for his outstanding work while at @RUturfCenter. Brandon continues his career at Purdue with @PurdueTurfDoc. Congratulations Brandon!

Reseeding safety after preemergence herbicides applied in May. Good ryegrass but poor bentgrass establishment from a mid-August seeding. For unplanned seedings, check herbicide label for safe reseeding interval, especially if seeding bentgrass.

It's the time of year to keep an eye out for goosegrass breakthrough. Standard pre programs provided good control so far, but closer inspection reveals goosegrass seedlings. Scout for seedlings and apply post herbicides before plants get too big.

Excited to chat annual bluegrass with @UTturfgrass next week. Note that NJ and PA credits offered.

Early emergence likely one of the reasons stiltgrass is problematic. Most have not yet applied crabgrass preemergents.

Great work by @KatieHDiehl publishing her work on ABW for Poa annua control AND landing the cover photo of the latest Crop Science. More to come in future publications. Thanks @theEIFG @NJTA_Turfgrass and @GCSANJcharities for funding. acsess.onlinelibrary.wiley.c…

Enjoy the weather today, and then join me, Mike Reed, and Matt Lindner online tonight from 7 to 8 PM. We will discuss grassy weeds and sedge control in L&L thanks to @NJTA_Turfgrass. Register: attendee.gototraining.com/r/…

Thanks to @NJTA_Turfgrass I'll be covering goosegrass in a free webinar tomorrow at 1 PM. I don't have many slides since @Turfman77 and @JasonOsterhoudt will be joining the conversation. Looking forward to attendee questions as well. Register: attendee.gototraining.com/r/…

Best part is the session is prerecorded, so @MSTurfgrass and I will be available and furiously typing to answer YOUR questions via chat throughout the session. Warm and cool-season turf.
