Cenlalowell Bermuda kill off trial

Post by CenlaLowell » Fri Sep 06, 2019 6:55 pm

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
