Poa Constrictor - Will It Eliminate Poa Annua? (Annual Bluegrass)

[@76MUTiger]

Thanks for your PNW perspective! I see other lawn guys in other regions who cannot speak to our environment, so I really appreciate your knowledge. I renovated my lawn last Fall in Beaverton with SS9000 rye grass mix from the Superseed Store. Now I want to take out the Poa that has emerged. I look forward to your updates to this video.

[@PacificNorthwestLawns]

I really should do a follow up soon.. I'll just say this, if the poa annua is well established, save yourself the money.

[@jwstein19]

Thank you for doing these tests for us! Many days of 95+ degree temps this summer in northeast Oregon did nothing to the poa in my yard. I resorted to an aggressive plant removal regimen. My thought was "no plants, no seeds." I know I didn't get everything, so I'm hoping my pre-emergent program helps out for next year.

[@PacificNorthwestLawns]

Honestly, a good pre emergent is going to work a whole lot better.

[@shadylawndude9488]

Sounds like you and me are in the same boat Jeff. As I’m mowing a rip them out just applied my pre-emergent yesterday

[@mikemorris8497]

Thanks for being the guinea pig. I live in eastern PA and kinda gave up on the POA. We’ve had over 20 days of 95+ degrees and the POA just keeps growing. So I’m looking forward to your results. If it works I’m in. Thanks.

[@PacificNorthwestLawns]

I'll definitely post updates. I'm not sure if I'm doing something wrong or not. I've read the label multiple times and have been following it. Maybe it just takes multiple applications. I do another one here soon.

[@Dsaubt]

Thanks for the video. I did a full lawn Reno and put down 100% Lesco Double Eagle Perennial Rye. Lawn came in beautiful. However I didn't get my lawn fully established until mid-October and got my Dimension down a little late. This spring I have very little poa, a few isolated spots that are very small, about the size of the bottom of a water glass. I think I am going to hand cut the spots out and just apply new seed or let it grow back in itself. I just don't want it to spread. Luckily my two neighbors next to me take care of their lawns and houses pretty well. The neighbors across the street are the complete opposite - salad gardens and they feed the birds.

[@PacificNorthwestLawns]

I have a few isolated spots in the front yard myself. I just hand pull what I can find before every mow. Each time I find less and less.

[@Dsaubt]

@@PacificNorthwestLawns right on.

[@shadylawndude9488]

I appreciate you show your efforts and struggles with poa. At least it makes me feel like I am not the only one lol. I’ve resorted to hot shots of round up in the spring before overseeding and then pre emergent in the fall. I read it’s going to take a long time somewhere between 7-10 seasons 🤦🏼‍♂️

[@PacificNorthwestLawns]

It's definitely a struggle. If this doesn't work long term, I'm going to kill it off again next year and start over but I will not forget to use the pre emergent this time.. 🤦🏻‍♂️

How did this product end up working out for you. I’m currently battling poa and trying to find the most effective approach. Thanks ahead of time.

[@shadylawndude9488]

Freddy how does it look? I’ve thought about doing the same thing but the seed is super expensive. I live in south Puget sound and I fight the same thing. I was hoping that it would die off this year with the heat but to no avail like PNW lawn. I guess that’s why TPC Snoqualmie ridge and Chambers Bay golf courses all switched their greens to Poa so they don’t have to fight it any more

Always wondered how Poa Constrictor work, read about it a lot but always wondered. Not that we are allowed to use or import it to Sweden, but still. Man they have to come up with a good answer to Poa, my knees are killing me from pulling it all the time. Awesome Nate!

[@PacificNorthwestLawns]

Thanks Sam. I need to do follow-up video. Spoiler.. it seems to be starting to work rather well.

[@coachkevin6229]

I'm interested to see the results. I did my 1st app of poa constrictor and tenacity just before Laboratory day and rained within 4 hrs of the app with no rain in the forecast. Didn't see any change. Applied my 2nd dose late in September. No rain this time, and after 2 weeks, I'm finally seeing progress,

[@zmjackson1]

Keep going! I found the best way to control poa a in my western wa lawn is scrape off top two inches of soil, renovate with high sand/all sand top root zone, bag always and use hands to catch any invaders. Chems are not the answer for everything.

[@PacificNorthwestLawns]

Interesting idea but there's no way I'm going to do that...lol. I'll keep trying this. Looks like it's gonna take some time to get it manageable.

[@drlovety]

I'm a little north of you and poa loves my yard. I did a reno last year because of the amount of poa and when Spring came, my poa was worse. I rented a sod cutter and removed the grass and brought in several yards of lawn mix soil, I figured I'd try to remove all the seeds hiding in my soil. I'm hoping this works, but who the heck knows what seeds are in the soil I just brought in.

[@PacificNorthwestLawns]

It very well could be worse than what ya had. Honestly the best way to prevent it is with a Fall pre emergent.

[@TheLawnShark]

Great and honest review! Appreciate your thoughts.👊

[@PacificNorthwestLawns]

Thanks Dino! 👊🏼

[@whereisthedollar]

We need Poacure (Methiozolin) in the lawn industry to control Poa and Poa trivialis. From Purdue " Two or Three applications of Ethofumesate applied needed. Results are rarely seen that autumn". I've used it before. It helps. But, I also just glyphosated a small area prep and reseeded too. Good Luck.

[@PacificNorthwestLawns]

PoaCure is way too expensive. $250 for a 16 oz bottle that only treats 4400 sq ft. No thanks. 😁 I'll keep plugging away at this .

[@SuperTA329]

@@PacificNorthwestLawns Does Poacure actually work ?

[@PacificNorthwestLawns]

@@SuperTA329 that's a good question. I have done some reading and there's a few golf course guys reporting that it works well. However, we seem to be a few years away from it being available to homeowners.

[@NextLevelLawnCare]

Poa is the devils grass. hopefully that combo knocks it back. Tenacity works much better at max rate imo. Everyone goes with the 1 teaspoon per 2 gallons of water(because that's what the syringe it comes with shows) then they still spray that over 2k sqft instead of 1k sqft because we are all trained that 1 gallon covers 1k.. Max rate is actually 1.1 teaspoon in 1.4 gallons of water per 1k sqft. And as a post emergent herbicide, surfactant is required for results. That being said its still not the BEST at some things, but I find its versatility with post emergent control and a short pre emergent window along with being able to seed with it makes it an amazing weed control.

[@PacificNorthwestLawns]

I plan on doing that here soon. That reminds me, I need more surfactant. 😬

[@Chrisbennett-k5h]

Label says use anuew in fall and spring. The research I read said it is best to start with it in fall and continue applications in spring along with ethofumesate.

[@PacificNorthwestLawns]

I did that and might continue here soon as we finally have a break in the rain but I'll tell you I did 3 applications in the fall and while it suppressed it, it definitely didn't kill it, at all.

[@PacificNorthwestLawns]

Actually the label on the Poa Constrictor specifically says to wait at least 8 weeks after applying any plant growth regulator.

[@Chrisbennett-k5h]

@@PacificNorthwestLawns Supposedly, you can keep it from going to seed in the spring with regulator. I just bought anuew, so have not had the chance to see if that works or not.

@@Chrisbennett-k5h I tried Anuew last year and it suppresses it but still came right back.

​@@PacificNorthwestLawns 8 weeks is quite a while. I will try to get an early start on overseeding. Hopefully it will have enough time to establish before a regulator app.

Hi Nate I'm already getting ready for winter I've cut back my water and I'm bringing down my height of cut put a little starter fertilizer and a good dose of bio-stim and a little experiment I have grown a turf patch and cut a area of poa out and put it in and see if it works and another area cut a section out added some composted soil and seeded and see if it comes back or not

do you have any ideas for California St. Augustine grass with a major Poa issue?

[@PacificNorthwestLawns]

St. Augustine is a warm season grass and to your advantage that opens you up to far better options than us cool season folks. That said, I have no experience with those particular herbacides or that grass type so I can't make a recommendation. There are however many guys on YT that have probably covered it. Try searching St Augustine Poa Annua in the YT search bar. I'm sure you can find someone better experienced with that than I am.

@@JLavoe111 exactly my point. No where on the label does it mention a pre emergent application process. It does however say to not water it in for 24 hours. That's why I question the pre emergent efficacy if it's only labeled for a foliar application.

Some of it does die, but most of it will get stunted growth. That’s when I just pull it out and put in some good dirt and seeds. I did buy and use that poa constrictor a few days ago.
