Lawn herbicide damage

Last week while spraying my Bermuda Lawn for weeds I inadvertently sprayed one patch of grass (200' x 12') with a herbicide (8.0% Glyphosate, 1.5% Oxyfluorfen, 0.1% Diquat). Well, it obviously did a great job killing the weeds, but it also killed this large patch of grass. I know that this is also in the soil and will probably prevent seeds from germinating for at least a month, but I wanted to know if it would be beneficial for me to bring in a couple of inches of new dirt and lay on top of the old "dead" sod and re-seed now?

Just wait a week and you are ready to go. These are contact post emergence herbicides and breakdown very quickly and do not prevent seed germination.

Since this is Bermuda grass, I wouldn't be so quick to assume it is dead yet, although 8% Glyphosate is very strong it may have done it in. I would water the heck out of it for a couple weeks before I would give it up as dead.

Also, if it is a hybrid bermuda lawn, you don't want to seed, as this type of turf cannot be seeded. The seeded varieties are lower quality and will not match the rest of your lawn. If you do have a hybrid bermuda lawn, I would buy a plugging tool and take some plugs out of your yard to plant in the killed area. The will fill in quickly to cover the area.

RE: Lawn herbicide damage

I agree with Tak. I've seen cluecless neighbors use common bermuda in hybrid bermuda lawn and it looks terrible...

RE: Lawn herbicide damage

I agree with the above and would add that any surrounding bermuda is not going to leave a bare spot for very long. Just leave it alone.
