KILL POA on a Budget - The Lowdown on the Best Method.

[@WeatherNut27]

I tried this and I am impressed! Horrible year for Poa. No tenacity available to ship here so I used .5 ounces of Torocity and 6 ounces of Triad Tz mixed in 5 gallon bucket of water.. Sprayed again in 2 weeks. Boom, dead. I'll be doing this next spring before it emerges. Thanks for the video!

[@TurfCulture]

Awesome! I’m glad you went for it. I was taught this method by a group of excellent turf managers.

Man, I have been pulling them out by hand. Unfortunately they are taking over my lawn. I wish you posted this video earlier, I will keep it in mind. Thank you for all you do

[@TurfCulture]

No shame in mechanical control of it, the seed heads are the real kicker.

[@WeatherNut27]

Did you use this spray?

[@TheLawngineer]

Oh man! This is a great video! Well done, sir!

[@TurfCulture]

Thank you sir! Appreciate you watching and commenting!

[@user-kj5uc9vo9d]

The drawback to putting down the pre-emergent for the seedheads in the fall is it's the same time of year that you reseed fescue. Might consider ethofumasate in that case.

[@TurfCulture]

You may have to sacrifice over seed for one season to get control of the poa. Give and take!

[@user-kj5uc9vo9d]

@@TurfCulture DId that last year (put down pre-emergent) but as you probably know, poa annua seeds can lie dormant for years. That is, skipping overseeding for one season is not enough; would have to skip overseeding for a few years. Instead, I put down ethofumasate which allows reseeding of fescue at the same time (which is coming up nicely by the way). We'll see how effective this is in the spring. In the event, I also have a big poa trivialis problem (poa annua is merely an annoyance in comparison) and will be putting down Velocity PM in the spring for the trivialis, which also happens to kill annua.

[@TurfCulture]

@@user-kj5uc9vo9d Agreed 100% on the efficacy but ethofumesate is labeled for use by licensed commercial applicators only, the only reason why I don’t recommend it to homeowners in this video.

[@darrickb1964]

Awesome info can't wait to try it I really wish I wasn't so into this grass game because I would have thought this was just weird looking grass years ago

[@TurfCulture]

You can’t escape it now!

[@arkrainflood]

i have used a weed torch (after rain while the grass is still wet) to kill poa in my tall fescue lawn. the fescue is of the RTF type. unfortunately it takes at least a month for the RTF is "heal" the burnt patches.

[@TurfCulture]

And the POA is prone to come back because the plant is still alive, just has burned leaf tissue.

[@nATHAN-rk9hf]

You sprayed both of those chemicals every week for 3 weeks? I always thought if you sprayed tenacity more than once a month it would kill the grass. Any tips to kill in the fall? Not sure if your mix killed or the heat did it. I want to kill before it seeds again in the spring

[@lettersandlove]

Great suggestions!

[@jfarm_1311]

Good info. Good to know that something works🤣. I’ve been hand pulling annua. I did find prodiamine in the fall helped in the spring too. Makes it hard if you need to overseed at some point though. Nice video Brandon!

[@TurfCulture]

Nothing wrong with hand pulling and then using a pre to control seed germination.

[@possession3929]

What rates did you apply at. I'm reading the triad application rate is (1.2 to 1.5 Fl oz per 1000 sq ft) so I use a syringe and that would be (35 to 44 ml per 1000 sq ft). Is that for a 1-gallon mix, 2-gallon mix of water or does water amount not matter. For tenacity I use (2.5 ml per 1-gallon water mix). I'm assuming combing it would be okay, but I want to know what rates per gallon of water you did to not harm the grass.

[@rkcadet]

Same here. I’d like to know myself!

[@TurfCulture]

There are max rates and low rates stated on the label. Follow the label instructions and apply at the lowest rate for each product and tank mix them together. I simply followed the label rates and instructions.

[@robertbarrett863]

I want to give your combination (Tenacity, Triclopyr Ester & Sulfentrazone 4F) a go at eliminating the poa annua in my tall fescue lawn here in Oregon. My question is about the use of a non-ionized surfactant. The Tenacity product says it requires a surfactant but the Sulfentrazone 4F product says "surfactants are not advised unless surfactant/sulfentrazone combinations have been previously proven to be safe to a particular turf variety." So, would you recommend using all three agents WITH a surfactant, WITHOUT a surfactant or do one application with only the Tenacity and the Triclopyr Ester in combination with a surfactant and then a second application a few days later with the Sulfentrazone 4F without any surfactant? I also plan to use Prodiamine 65WDG as a pre-emergent separately in the Fall and again next Spring. Thank you.

[@TurfCulture]

Since you are applying at the low label rate you’re fine to add a surfactant.

[@jpzsports]

@turfculture - checking in to see if the triv came back or if the combo ingredients worked well?

[@TurfCulture]

This method works wonderfully on poa annua, the only way to get rid of the triv is glysophate.

[@michaelireland4191]

When your applying the pre emergent are you not seeding in the fall?

[@TurfCulture]

No, you cannot do both.

[@rodrigoalonso9196]

Hey, just checkin in a a couple years later. Are you still happy with the results from this mix? Starting to deal with a lot of Poa on my new lawn reno. Thanks

[@TurfCulture]

Yes! I am happy with the results on the poa annua. This process with burn the leaf tissue on triv but wont kill it. Glyphosate is the only option for triv. Also, I am not sponsored by any chemical companies, this process was recommended to me by reputable sports turf managers.

[@tommybennett737]

I see you linked tzone is that what you used? Or straight triclopyr? Also what about surfactant? I use one with tenacity but not sulfetrazone?

I linked Triad TZ it contains both active ingredients. You can use a surfactant if you want to.

[@SteveHeim-dw2qy]

How long did it take after the application to see that the POA was starting to die?

[@TurfCulture]

next day I could tell the poa was starting to suppress.

[@SteveHeim-dw2qy]

@@TurfCulture Thank you for the reply. It's been a few weeks so I can share my experience. I had about five patches of Poa Annua (the really seedy stuff) in my shady back yard. Honestly, i think my irrigation was set too high for the shady condition and created wet spots. It seems the Poa settled into the wet spots. When I first posted, I was almost a week into the first application of Tenacity + Triad. It was yellowing the POA slightly, but didn't seem to be killing it. I was probably a little light on the mix as I feared harming my turf grass. On the second application, I adjusted the ratio to about midpoint (between min and max). Wow, did that stuff die! The turf grass did bleach slightly around the edges, but is already showing recovery. I did not even bother to do the third application as I would have been spraying bare spots. I just reseeded the bare spots yesterday and am hoping for good germination. Next step will be trying to time preemergent to avoid having to deal with it again next year. For what its worth and hoping this helps someone!

[@kbgking7921]

Great content as always. Did you use pre emergent in the effected area? I wondered how effective it was against poa.

[@TurfCulture]

No, only in post.

[@Cuzntime]

If I use Prodiamine in the Fall and Spring, when can I use grass seed to fill in the dead spots from the Herbicide I used to kill the existing Poa that was in my lawn?

[@TurfCulture]

It would depend on the rates that you are using, if you apply a pre for 4 month control you are good to seed at that time and then continue with your pre application in the fall.

[@BenNawrath]

So did you get any bleaching from so much tenacity? Also, I’ve been doing mini sod farms for patching. Plastic under-bed storage containers with some holes drilled, couple bags of soil, and seed. Self made sod patches of whatever seed you want!

[@TurfCulture]

No bleaching issues here

Depending on which products you are using and the concentration of active ingredient I would suggest going off of the label at low rates.

[@majikman7355]

3 applications within 7 days....How much does your cocktail mixture cost?

[@TurfCulture]

1 application, every 7 days, 3 consecutive weeks at the low rate.

[@davidhires7403]

Are you convinced your cocktail killed the poa not just the the heat? I’m in Seattle and my poa doesn’t die off in summer. It it stays all year. I need something that will kill it. Do you think your solution will kill it without the heat?

[@TurfCulture]

The annua did die, triv not so much.

[@NathanCrosty]

@@TurfCulture Did all of the triv come back? 100% as bad, worse, or you reduced the problem a little bit from when you sprayed? An update on this would be fantastic

[@cunninghamlawncarellc1695]

As a professional applicator, I can say Prodiamine is terrible at controlling Poa Annua. At least in the south. I have tried combining it with Simizine as well. Very bad results. I have seen better results with Dimension 2EW and one extremely expensive product is called Specticle Flo. That one is fire for preventing Poa Annua. Are you still having luck with Prodiamine in your cool season grasses?

[@TurfCulture]

Prodiamine is only good for suppressing seed heads the following year.

[@marcl9232]

How are you going to seed your thin spots but apply prodiamine?

[@TurfCulture]

You can time the applications appropriately, also amending the soil will break up the pre-m vapor barrier.

[@timd5597]

Did you water in after each application?

[@TurfCulture]

You can water it in after a few hours

[@johnavgoustis3372]

Yes, that is why you would want to use a pre emergent in the fall.

[@bear532]

@@TurfCulture Since I did a full lawn reno last fall and knew I would have to seed bare patches come spring, I couldn’t apply pre emergent for poa (I did spray tenacity). It’s ok though, poa may be stubborn, but I’m more stubborn. Spent many hours this week hand picking all the poa. Nipping this in the bud before it takes hold. I’ve completely filled 6 5 gallon buckets and I’m about 75% done. I really hope this makes a huge dent on the poa population for the foreseeable future. Obviously, I will be applying pre emergent once my bluegrass fills in nicely and there’s no bare patches that need seeding.

Interesting stuff. Poa triv is extremely tough to kill besides Glyphosate and many have tried different things that they thought killed triv but it ended up coming back in the fall. Do you really think the triv in your yard was killed off?

Probably not all of it, I’m expecting to treat for triv again next year and use a pre for and annua seeds that germinate next spring.

[@jpzsports]

@@TurfCulture How has this been working for you? spending literally hundreds of hours spraying, digging out, and reseeding all the poa triv patches I could find over the past year and recently pulling out 1000sq ft, I found another 10+ patches today that seem to be thriving after the cooler temps have hit and all the recent rain. I just can't keep up any more. I've come to the realization that triv loves the shady, wet areas. I basically give up. Curious to know if the areas you had triv and sprayed this mix are still dead or just were dormant and are coming back?

Hate to be the bearer of bad news but you'll get all of that triv back next spring. Tenacity does nothing to kill that. Best way I've done it is to kill it with roundup in the early spring and seed early enough so that the summer heat won't get to the new grass.
