Anyone have a link that still sells the smaller packets? I have some Poa I'd like to kill but can't seem to find a site that sells the 0.5 gram packs.

I don't think it's labeled but... I've kill poa with Celsius at the max rate, only one application so it maybe effective at lower rates.

I know that's not your question, just putting it out there.

FWIW, the Certainty label says it will take care of it too.

 

[Movingshrub]

I think the key is going to be the maturity of the plant and how many there are to control. If only a few, pull them.

According to the Certainty label, best results are obtained when poa annua weeds are in the early stages of growth and prior to tillering.

Quote from UGA Cooperative Extension Bulliten 1463 - Annual Bluegrass Control Programs from Georgia Lawns.

"Turf managers using Celsius (thiencarbazone + iodosulfuron + dicamba), metsulfuron (Manor, MSM, others), and sulfosulfuron (Certainty) may control seedling annual bluegrass, but applications do not provide acceptable control of mature plants."

I used a mixture of prodiamine at 0.75lb/acre, one 5 gram packet of monument (putting me at the max rate equiv of 15g per acre since my yard is 1/3rd of an acre), and simazine at the rate of 0.75 fl oz per 1,000 sqft.

No poa annua at all in my yard.

If you haven't bought certainty or monument, I'd suggest considering katana. I think it was cheaper in price per application than monument and will get tillered poa, unlike certainty.

There are some 5 gram packets of Monument on ebay for $71 shipped.

Has anyone try to use Tenacity on non-dormant bermuda? It is not like it is going to kill it. We all know it doesnt die.

Are you set on monument?

I haven't tried that before. Was your question checking the viability of blanket spraying Bermuda with tenacity to control poa annua specifically, using a blanket app to control winter annuals in general, or something else entirely?

 

[high leverage]

I ran the numbers on Certainty, Monument, and Katana a few months ago. If my math is correct Katana is by far the cheapest per 1000ft2 at $1.44 and can be reduced even more when tank mixed with Urea (46-0-0). Certainty came out at $2.61 per 1000ft2 but as Movingshurb pointed out above is not effective on mature plants. Monument is the most expensive at $5.79 per 1000ft2.

So the question is when will Katana replace Certainty in the majestical "Bermuda Triangle"? Lol @dfw_pilot

Glad to see I'm not the only one to make that suggestion. If you're making a Bermuda/zoysia only Bible, then monument or Katana and call it a day.

However, katana isn't listed for St. Augustinegrass and monument isn't listed for centipede.

Revolver would be another contender also for poa control but none of the aforementioned items are as compatable as Certainity.

I wish I had your herbicide budget. :lol:

I second high leverage.

I think my winter pre-em of monument, simazine, and prodiamine came out to about $65 for the application and the spring app was $10 worth of prodiamine and simazine.

Touché. :lol:

I'm sure those are all great products or they wouldn't make them, and maybe I'm just living right, but weed control is not something I've struggled with.

I agree. There is nothing better than dense turf to keep the weeds out. And by the looks of your lawn you check all the boxes. Keep up the excellent work. Nothing but respect. I know a a lot of golf courses that don't hold a candle to your lawn. :thumbup:

@dfw_pilot No disrespect on the Bermuda Triangle. It is a sound cost effective approach. In fact I believe Certainty is still the cheapest to control nut sedge. But maybe Katana is more versatile.

I'm a cool season guy, so just wondering. Tenacity is so inexpensive. We use tenacity for poa annua control in the spring. 2 oz/acre rate in blanket (make poa shine), repeated by 2-3 spot weekly treatments. It might work on Bermuda too.

 

[dfw_pilot]

I too, have very few weeds to deal with. There are lots of good herbicide options and "there are many roads to Dublin."

Am I missing something. Tenacity is labeled for pre-emergent POA suppression not Post emergent. There are far cheaper option on the warm season side for pre-M POA than Tenacity. Simazine or Atriazine.

 

[g-man]

Yes, we use it off label as a post emergent. Our POA annual germinates in the falls, it goes dormant in the winter and it is full tiller in the spring. PreM in the fall works, but sometimes a few still manage to grow.

I'm just curious if anyone has tried it on non dormant Bermuda.
