Cenlalowell Bermuda kill off trial

Post by CenlaLowell »

Here's what I'm trying start this fall. I will try to kill off the Bermuda in my yard. The yard I have now is about 60/40 or 50/50 give or take.

First the chemicals I have on hand

Tenacity+simizine
Ethofumesate+atrazine
Glyosphate

Wish me luck in this endeavor

Okay first experiment

This section is about 590 sq ft and has about 60/40 ratio with St Augustine in the lead.

Now I've sprayed this with ethofumesate 1/2 oz+atrazine 4 oz. Both are label rates and this took place on 9/4/19.

Here's the shot I'm probably going to use from here on with this area. It shows some discoloration, but I don't know if that's from pure heat or my chemicals

Would you say this has been effective? Or too early to tell? Any damage to the st. Aug? What air temperatures are you spraying at?

I think it's to early to tell. No damage to the St Augustine and the only time I spray is between 5-6 am. I will buy a 1/2 gal of ethofumesate and a gallon of atrazine for the spring and I will make a clear determination next year

New update. Still don't understand this.
Image

Some areas of the Bermuda loss color and this area loss all color. Now, the article I read said it was better to do this in the spring also. So, I will hit it hard in the spring time as well.

I'm using XR teejet nozzles and now I'm wondering if it would be better to use the TT teejet??? Advice

I spot sprayed a spot in the front yard and now I'm 100% it works as far as browning it out and stunning growth.

What I don't know is how long will this last and should I increase the rate of atrazine for even more effectiveness

Atrazine 8 oz and ethofumesate 2.25 oz 1k. I'm going to increase the atrazine by 2 oz every time I spray or until the St Augustine can't handle it

Update

Ok I now have a better understanding of this experiment. One there's no killing Bermuda short of glyosphate and maybe plyex(cool season).

Next, what seems to happen is more of a suppression. Bermuda turns really dark brown, but it's not dead at all. So I read the label and I sprayed this at the wrong time of season. Which is posted here⬇️⬇️⬇️⬇️
Image

So here is the new update of the lawn. This process will work but you will need to be very patient. Also this will not lead to a 100% removal of Bermuda in my opinion, but I'm just trying to get to 90/10

End of the season review.

First, this combination of chemicals does work for SUPPRESSION. there will not be any kill off of Bermuda what so ever. So the goal here is to see how much I can The St Augustine to take over.

Since this is a spring time combination I will spray next year in March and April then towards the end of the 2020 season see if the St Augustine has made any headway.

Lord willing

Hey @CenlaLowell, I think we talked about this combo last year so I'm very interested in your results!

Question, what strength Atrazine are you using? The only liquid atrazine I have is made by Hi-Yield. It's in 32oz bottle but only has 4% AI (max legal strength I can get I think). So 8oz/m of that would be only 0.32oz AI, or a little under 1 pound/acre...Is yours different? Max rate of atrazine AI is about 2lbs/acre I believe.

I'm going to try the lazy route to suppress or kill my invasive bermuda in my front yard this year with this cheap weed and feed with 1.39% atrazine. By my math 4lbs of prills/m (bag rate) would contain 0.89oz of atrazine...or 2.45lbs/acre. I think yearly max is 2.5lbs/acre.

I hit the lawn with a healthy dose last night and plan to spoon feed it weekly or bi-weekly the rest of the year to limit runoff. Maybe the bermuda won't like the constant harassment...time will tell! Good luck with your trials.

What I'm thinking is the suppression would be enough to let my st Augustine win the battle. My Atrazine is 4% as well. I'm going to spray this week coming, I believe and this is what I'm using. I never thought about weed and feed with atrazine. Seems like an expensive undertaking especially if you have a big yard.

I think you would need about 22 ounces of that liquid to equal the same amount of atrazine as 4 lbs of the granular W&F. Without doing too much drunken math, $11 per M for the liquid Vs about $4.25 for the HD granular/m? Plus you get the N and K...

My plan was to buy the cheaper W&F from Walmart...it has a similar concentration of atrazine as the HD stuff in a bigger 20lb bag for only $11 (~$2.50/m), but they were out of stock when I got there so I went to HD. www.walmart.com/ip/Rite-Green-St-August ... b/16782620

After learning the expensive way that the best broadleaf herbicide for my Floratam turned out to be the cheapest I own (MSM turf), I have no problem trying the cheapest solution possible. Celsius and Certainty left me wondering why I bought them...

I think the atrazine has some pre-M properties, so maybe spoon feeding all season will keep the common bermuda seeds from sprouting too? Dunno, can't hurt.

Great find on that Rightline stuff! Last year I was looking at Prograss or Poa Constrictor $$$$ for the same AI. Your mobile links are unreadable on a PC, just an FYI....

Celsius and Certainty are really good products as well. Matt Martin did a video on MSM and why people should use a sparingly. Okay on to the task at hand. Remember atrazine is going to turn your Bermuda brown so I'm only doing this experiment in the spring and maybe fall. Fingers crossed
