If the temp was over 90F there may have been some damage. Bermuda is resilient and will eventually come back or spread in from the damages edges. Keep it watered.

When the temp gets over 90F use at half Strength.

Bermuda32: how is your grass doing now? did it fully recover?
Neilaz: will 1/2 strength still kill the weeds?
How long after application of weed b gone do the temps need to stay under 90F to be safe?
Thanks

I still get a good kill rate of the weeds at 1/2 strength. For me it is spurge that i have to deal with. It may take two apps but it will work. I apply after dark (still over 90F but sun is down) then water say at noon or before.

granburyflowergirl...

As of today, my lawn has recovered. Some of those yellow spots eventually caused some of the bermuda to die, but in other spots...it didnt. Very odd to say the least. Where some of the grass died, the surrounding bermuda has already overtaken it. It's almost like I never sprayed my lawn :)

What I did do though is put on a heavy-nitrogen fertilizer recently and now the crabgrass issue I was having isn't really a problem anymore. In my part of the country (NC), we are in a drought. Everyone's lawn in my neighborhood is dried up and crappy looking. I don't think my grass has ever been greener.

Needless to say, I am happy that bermuda is such a tough grass.

bermuda32, so are you saying using the high nitro fertilizer caused the bermuda to choke out the crabgrass? I too have a crabgrass issue in my bermuda and put down some urea 35-0-5 fertilizer in hopes my bermuda will take off and win.

Ortho Wee B Gone with Crabgrass control has Quinclorac as one of the active ingredients and will bleach/set back most if not all Hybrid Bermudagrasses, however, the common types are not affected.

Also, apply during the early morning hours when the air is cool and the winds are calm. Do not exceed rate during the summer months.

One last thing, rainproof in 6 hours.

Bermuda32: Thanks, that's good to know!Glad your lawn is green again.

Sunfire: where did you find urea 35-0-5?

auteck: are you saying that using weed be gone may cause your hybrid Bermuda to be overtaken by trash Bermuda?

I am trying a new experiment in part of my lawn that is remote and was way more crabgrass than Bermuda: smothering! I am hypothesizing that the crabgrass will die from smothering but the Bermuda will come back...(this is in a spot that I may mulch over anyway for a path so if it all dies no big deal). I'm basing this theory on observations of the patch of land that had a 1000lb bag of sand sitting on it for a month. I'm just not sure how long to leave the piece of particle board down to kill the nasty crabs...

granburyflowergirl: I got the 35-0-5 urea at Home Depot. Its labeled under Vigoro Super Green. Let us know about the smothering experiment.

Wee-B-Gone without Crabgrass control does NOT affect hybrid bermudagrasses. Quinclorac is the active ingredient that kills Crabgrass and will bleached hybrid bermudagrasses, however, the common type Bermuda is not affect it by it.
