    I recently used Speed Zone to kill some clover patches in my fescue lawn. I noticed it made the grass a little brown as well. I hope that is just temporary. It is same mixture I use for dandelions/weeds. Used 2-3 ounces per gallon. Did I burn the fescue a little too much? Maybe the mixture was a little strong?

    What was your application rate?

    Just walking around spot spraying 1.5 acres. Maybe too heavy for each patch??

    probably a bit much, whats the high temps over there? I spot treat with speedzone, and use about .75 to 1 oz per gallon for spot treatments, i don't go crazy with it either. More isn't always better.:laugh: lots of good info on the label too!

    I think probably too heavy and too much Speed Zone. Hope the grass recovers. It has been in the low 90s here in eastern KS.

    mabee its just tip burn? I just don't spray much fescue here. I have fescue in my back yard, i only mow it at this time of year, no treatments. Mine is ate up bad with brown patch from all the afternoon showers.

    you mixed it a little strong. i use it at 1.5 oz per gallon or 2 oz per gallon at the most.

    the grass will probably come back though.

    It is best to test out your sprayer buy putting in one gallon of water. Spray a concrete parking lot; measure the amount of sqft the gallon covered. Mix according to the sqft you cover. Cover weeds with the same amount of liquid.

    Do not spray weeds when you are angry with 'em. Just get them slightly wet and let the chemistry do its job.

    My test with Speedzone this week obtained good results. I mixed 1 ounce per quart in a squirt bottle and aplied one squirt to each weed.

    That would be 4 oz per gal which seems heavy but not for individual weeds I guess. I usually go 3 oz. per gal for dandelions alone or in the grass. In this case I was spraying small patches of clover in the grass and just kept sweeping the patch too long resulting in a overdose.
