Will this product kill Saint Augustine grass invading tall fescue?

I think it will. But I would do a small test plot ( maybe about 3'X3') to see what it will do in my situation. Be careful to follow the manufacturer's recommendations as closely as possible and let the grass grow at least a month before judging how it performs. This should be done during the growing season for both grasses.

I do not have familiarity with this grass, so unfortunately I cannot help you with this question

Yes it will, It will kill anything you spray it on. Be careful around your good lawn.

Yes it can - I live in FL and have Floratam (a St Augustine variant) You may need to remove every other row of tines as shown in my review. I have used with all tine rows populated, but eventually the motor overheats and shuts down - too much stress on the motor. With every other row used, the motor keeps going and I saw no substantial difference in the amount dead grass pulled up.

I have know idea because we don't know anything about St Augustine grass. We use on Kentucky Blue grass and it does a fantastic job on the crabgrass. We use each year in early spring. I'm sorry that I can't help you further.

Works for me on actively growing crabgrass with less damage to fescue lawn than MSMA, but not as quick a kill.

I would doubt it. This kills grass and weeds well although there are some "tough" weeds that require a higher concentration. I've used it to kill weeds in ground cover evergreens where it gets the needs but not the evergreens (they may brown a little for a time). Maybe if you used a much higher concentration than recommended for weeds?

Yes, it will. It is designed to kill just about any living tree, shrub or plant. Be careful.

You can use Scotts crabgrass preventer with HALTS on St. Augustine as long as you do not overapply. If you overapply, it will burn the turf. If you use a Scott's spreader, use setting 2 1/4.

This herbicide works fantastic on removal of Bahia grass in your lawn. I used it in a lawn of St. Augustine and centipede, with patches of Bahia all over the yard. I used a pump sprayer and spot sprayed each patch lightly. after a summer of use with this product I removed every spot of Bahia from the lawn. this product will burn the other grass a little (turns a little red) but it recovered in no time. I used the MSM that came in white pellet form, you will get a measuring cup with the product. fill this cup to the bottom line on the cup. I put this in a Gatorade bottle with a little water to mix the pellets good by shacking the bottle vigorously (with top on bottle). then put this measurement in 1 gal of water. (just a dab will do the job). my 1- 2oz bottle will last for many years. this is very good herbicide to rid Bahia from lawn. Good Luck.

I used this product in the fall (sept/oct) on a section of my lawn that had Bermuda grass. I won't know if it killed off all the Bermuda grass till the warm weather (June) However I think it killed my lawn too. BE CAREFULL IF YOU USE IT.

I have sprayed twice at the end of this season,,30 days between sprays,,so far the bermuda grass is dead.The tall fescue has been completely unaffected.I will spray again in the spring,as directions call for..I have tried many products trying to kill the much unwanted bermuda,so far the Ornamec has worked.Directions state that it usually takes 2 seasons to completely kill the devil grass..So far so good!!

I only used on lawn so sorry I can't answer this question. It did not harm my Tifblair Centipede or St. Augustine grass. It did get rid of Bahia and wild burmuda.

It appears to have killed a good portion of my fescue grass. Half of my yard is now brown, I'm hoping the grass will come back with the rains here in California during the winter. How did it work on your lawn?

It works just fine. Follow directions. Will probably take more than one application. I spot sprayed on the Bermuda grass. Know that there is a possibility that your fescue grass may brown a bit but this will come out of it. Don't spray in the heat of the afternoon as this seems to cause browning of good grasses. Get the Bermuda grass wet and be patient, like was said earlier, will probably take more than one application. The label on bottle will tell you how often to repeat spray- BUT FOLLOW DIRECTIONS!

According to the label, this product can be used to "suppress" the growth of tall fescue (such as in orchards, etc.) if it is growing vigorously at the time of application. After two years, the Bermuda grass I treated is back with a vengeance. Perhaps I needed to do two applications as now I have more Bermuda than before.

i'm too dumb to know what tall fescue is and i was too lazy to look it up. i used it on what i believed to be fungus on St Augustine and it did nothing to help the problem. However, i'm not positive the problem was fungus.john bland, gainesville, fl

Atrazine is a very effective weed killer for St. Augustine grass. Be careful though, it will kill many other grasses. From what I can tell, you can't buy St. Augustine seed, but have to plant sod or plugs.
