I'm having trouble knocking back Poa on Tifgreen 328 Golf Greens. Applied Revolver at .40 with moderate success but would like to see better.

Thinking of trying Rimsulfuron. I've Never used it before. Any users out there? Results?

What do you think?

 

[greendoctor]

Are the greens greening up? If so, Rimsulfuron or else Flazasulfuron are possibilities

 

[ArTurf]

Starting to greenup but a ways from full.
can you be more specific

 

[greendoctor]

If they were not greened up, Diquat or Glyphosate or Glufosinate. Since they are starting to green up, Rimsulfuron or Flazasulfuron.

I haven't tried Negate (rimsulfuron) or anything else that contains it yet.

But I don't think it would hurt the green.

Rimsulfuron is labeled for Bermuda greens. So is Flazasulfuron.

Do you think one over the other would be more effective?
I'm was considering Rimsulfuron at 1oz. but really wasn't aware Flaza was labeled for greens.

Almost seems the Poa is showing resistance to Revolver

Flazasulfuron + some Urea tank mixed seems to be a pretty sure killer of cool season contaminants.

I am sure Rimsulfuron + 0.1 lb Urea N/M will perform as well. Flazasulfuron has a dual use in that it is also active against sedges. Labeled for weed control on greens.

I’m with Rey on this one. Flazasulfurin is the go to here due to efficacy and labeling.

And yes, *Rimsulfuron will nuke the poa in 14-21 days @ .25oz/a.I. per acre + MSO @ your preferred rate. Water that in on day 2 if possible.

May want to consider a Flumioxazin/Gly app at 12oz in the January timeframe on the greens to cleanup - unless you use Oxadiazon. This will easily keep them clean through August with no ill rooting effects.

* Rimsulfuron will delay greenup

Do you work on greens much?

Thanks for the input CAN & GD

Any idea what effect Rim might have on Bull Paspalum ?

 

[grassmasterswilson]

Not golf greens but I considered trying some negate( rimsulfuron + msm) but msm doesn’t do well in cold weather.

I think the stand alone rimsulfuron is not labeled for residential

Might mess it up a little. I know Metsulfuron, Iodosulfuron, Trifloxysulfuron, and Foramsulfuron are very hard on Paspalum species.

Flumi and gly mix on greens seems risky to me

Gly is sprayed locally on 328 greens at a muni track. Only issue I see is algae. Aeration is never done, yet a quality calcium product would relieve that.

Maybe a dumb question but what is a muni track ?

Municipal Golf Course (local government owned).

Do you do the apps on this golf course ?

I spray for the local golf course with 328 greens (for the most part). While I'm knowledgeable on regular cut height grasses I have some questions specific to greens height grass. You care if I bug you with questions? What grasses do you deal with on the fairways and roughs?
