How do you KILL Bahiagrass that invaded St Aug Grass

Bahiagrass is getting a step into my lawn. I have tried Bonus S and a weed killer that will not harm St Aug but the darn thing wont die. I really do not want a Bahi/StAug yard but do not know what else to do? Any product that will kill this grass and not St Augustine?

Good Luck…..

I asked Lowes and the lady told me a liquid form of, “Atrzine” I hope I spelled that right. It is ok for St Aug and Centipede grass but will kill everything else. I tried it but that darn Bahiagrass is still growing.

Are you absolutely sure it is Bahia Grass?

yes, I searched online and found pictures of it and it matches the garbage in my yard. It is a small problem now and before it gets crazy I would like to knock it out.

Doc, Standard Golf Makes a Product called a Weed Pro. Its a wand with a foam tip on the end. Go to Standardgolf.com and Go to products then click on Turf Products III The weed pro is there. I suggest you Put MSMA in it and spot treat your Bahia NOT the St Aug. We sometimes use this method with Acclaim on Bentgrass greens for Goosegrass. with little to no damage to the bent. Its the best I can do for now…..

Take Care and Good Luck…..

Atrazine seems to work, if that is how it is spelled.

Doc,Atrazine will work to control some weeds but don’t expect that it can be applied with impunity. I did just that and my 22K ft(2)St Augustine front yard looks like a UNF testing plot for every kind of weed from Alabama to Zanzibar. Atrazine will most definitely kill St A. And every other living herb it touches. In all fairness to its manufacturers, I didn’t follow label directions and am paying the price.

I use a product from Lesco called Riverdale Manor and it works great. It takes two applications from a hose end sprayer, six to eight weeks apart. It is a selective herbicide that provides control of Bahiagrass and other broadleaf weeds.

Cohiba has the right idea. Here is the poor man’s approach. Get roundup or MSMA and a sod plugger or 3″ piece of PVC pipe. Put the plugger/pipe over the bahia and spray it with roundup or MSMA. This limits the damage and should kill the bahia.

Good luck!

Take out bahiagrass with treatments of the new Manor herbicide or arsenicals. Control sedges with Basagran, Image, Manage or repeat applications of arsenicals.
