.... Also, there is a new herbicide out that works for a lot of grasses including st. augustine. It is for broadleaf and weedy grasses. I used it on my St. Augustine this year and I am really happy with the results. My dad used it on his bermuda and was happier with that instead of mixing combos of msma and other stuff.

I used the medium rate in late March on the St. Augustine. My dad used the high rate on his bermuda. A few things you should know though.
1. It is expensive. $100 a bottle. Covers 3 acres at the high rate of application.
2. It only suppresses dallisgrass at the high rate. You can add Revolver to it to kill dallisgrass, but only add revolver to it if you are applying to Bermuda. As I said, I used the medium rate on my st. augustine. Letting the St. Augustine grow taller and flourish has helped get rid of the dallisgrass. Spot treat dallisgrass early with roundup. Let the good grass fill in.
3. It only lasts about 3 months after the application. I didn't have any crabgrass at all until late July from my March application. That's impressive.
4. Bermuda can handle just about anything except atrazine. It is a pest in my yard. I usually put an application of fertilizer with atrazine to help keep the bermuda back in my st. augustine lawn.
5. Also, do not apply it at the high rate on St. Augustine and especially don't spray it after temps get above 90. It will stunt the st. augustine and that's when the weeds fill in.
