And I understand that some are "slowing" or stunting Torpedo growth. What are the different recipes being used in st. Augustine

 

I have battled torpedo grass for a while now in my St. Aug. If anything, selective herbicides seem to weaken my grass and the torpedoes grows in even worse! It is an extremely hearty and thick weed. I have pulled out some that are 10" with their root.

I tried picking it out by hand little by little but I gave up!
I would like to try Recognition, once it is released to the public.
Until then, I just try to ignore it and bag my clippings.

It's available to the public. Just hard to find right now. Just call around to landscape /chemical supply shops. I know a guy who got 2 bottles today

 

The Recognition label states that Recognition alone provides suppression of Torpedograss; I imagine adding Fusilade would offer better control.

I would think that if the safener in Recognition were of any benefit to Torpedograss, it wouldn’t provide any suppression by itself.

Try it out and report back!

 

I have not had any success with torpedo grass using the "high" label rate of Recognition/ Fusilade.

However, this is 13 days after application with Fusilade 0.75oz vs 0.55 oz. St. Augustine appears to be doing well.

 

Spray it all with roundup and re sod? I have been thinking about it for years. I have a big area that is dominated by this stuff for years. Haven't been successful at all

 

and in my area is difficult to get clean sod as well.

 

I just read on a FB page that people are using Recognition + Fusilade + Quinclorac on St. Augustine to eradicate Torpedo grass...if this is true I have a weedless yard🤔

 

Here is the 3 way combo in action.

The addition of quinclorac DID cause some pretty immediate damage to the SA lawn however it seems to be rebounding nicely. The torpedo grass has NOT come back


I'll pick the experiment back up in spring

Hey @redspot321 do you recall the rates per gallon for the three herbicides that you went with? It looks great btw

I used .045oz Recognition / .55oz fusillade / 1.45oz Quinclorac

Note! There was damage to the SA. Thankfully it seems to have injured the grass blades where it came in contact with the herbicide, not the stolons/roots.

In the spring Ill try again with 50% of the Quinclorac (0.725oz) to minimize the damage to my SA.

Here is an example of a spot treatment 12 days after treatment. Spot treatments are tricky and can easily be overapplied.

 

Final update. Very happy with results!

 

I'm having this issue in st Augustine now. It's completely infested with torpedo. Was thinking of ripping it all up and putting in zoysia but if there's a cheaper option to try, I would totally go that way

 

Suppression of Torpedo grass from Recognition/ Fusilade now that’s funny. Anyone who’s dealt with Torpedo grass knows it should be called “impossible weed”. During my cooler months my Torpedo grass will slow down in Central Florida and brown up a bit. That’s suppression in my book, and I get it for free every winter, but it has no impact on this impossible weed long term. The only herbicide I know that will nearly wipe it out is Glyphosate. I agree with previous comments if you want it out of your lawn then two passes of Glyphosate across two applications. Rip out your sod and move to Provista St Aug to keep your lawn nearly free of this impossible weed. Btw, take a look at Lawn Care Nut YouTube channel and look at his results from Fusilade and Recognition. Allyn’s pretty experienced with applying herbicides and from what I can see he wiped out his St Aug on a quest to remove bermuda, and the Torpedo is still running strong.

 

Recognition + Fusilade + Quinclorac on St. Augustine to eradicate Torpedo grass. It works! Read the entire thread.

 

Anyone else have a chance to give this a shot? I have one patch of toroedo grass in my Empire and 2 consecutive spot treats with 1tbspQuin/2tbsp MSO didn't even phase the torpedo.

Speedzone southern didn't even ding it either.

 

I'm going to do a side by side test tomorrow morning
1. Recognition/Fusilade
2. Recognition/ Fusilade/ Quinclorac

I'll report the details

 

@UFG8RMIKE Not surprised about the Speedzone but I would have thought the Quinclorac would get it.

 

I keep reading that it does, it smoked the crabgrass and it’s also taking care of all the st Augustine. I’ll give it a bit longer and hit it again. I’ll beworking on the doveweed this wknd with blindside.

redspot…please let us know how it goes.

9 Month update - There is sporadic Torpedo in the treated spot and a small patch where my wife drives on the grass I'm going to hit it again this week when I get the opportunity.

 

Wondering if the torpedo grass came back this year?

Also, I'm not familiar with the combination of Recognition + Fusilade + Quinclorac. Would this combination work on centipede? I'm currently battling torpedo grass in my St. A and centipede lawn. I've tried some other selective herbicides on torpedo with no luck.

 

So, cutting the Quinclorac dose 50% worked?

 

I haven't had time to try the reduced rate yet.

 

So, other than temp damage at the full rate… all turned out well and the St. Augustine rebounded?

 

That's correct

 

90% is excellent will most likely require annual treatment to control.

I might just paint the remaining torpedograss with glyphoste.

Was that the full rate of Recognition/Fusilade/Quinclorac?

Yes.

I still want to dial the dose in to prevent collateral damage

I saw little to no damage to the St. Augustine.

 

Pro Vista is not a good option for Floratam replacement if you have any kind of traffic. Regardless of what Scotts says, it requires more fertilization and is a dwarf variety that grows slow. Any kind of traffic will require regular aeration and will never be a thick plush lawn. If you push mow, have no pets or kids and love to water and fertilize, good luck.

 

I recommend Zoysia if you have a HOA that will allow it, weed control is much easier
