    I am in north Alabama and the Dallis Grass is still green. Can I kill it with MSMA this time of year or will I have to wait until next spring. Any other suggestions for killing the DAllis grass?

    I HATE Dallis grass. Somebody help!

  3. MSMA will and I belive Drive and Acclaim will also, but I don't have the lables infront of me to check and make sure.

    You can still kill it, but once the first frost comes by you it will be gone for the rest of the season till it gets hot again.

    MSMA will kill dallis grass. What kind of grass is it? It is NR on certain types of grass. If it were me, I wouldn't worry about it because it will be gone in a couple of weeks or so, unless your in a really mild climate. Dallis grass is difficult to control, usually pre-m will not even control it.
  5. It is often mistaken for crabgrass here.

    MSMA will kill dallisgrass but it will take at least two applications 10-14 days apart. There are other herbicides out there that will also work. Primarily those that work on grassy type weeds. Dallisgrass is a perennial grass that initiates growth from rhizomes as well as seed so pre-emerge won't work. Plan on several seasons to totally elminate the problem.

    Check into Ally or Manor. I have used Ally to control bahia and it works like a charm. I am pretty sure it will knock out dallis. By the way, my supplier told me that Ally and Manor are the exact chemical. Manor is labled for lawns, Ally is labled for farm use. Manor is about twice the price. Ally is expensive enough. I've been using it on horse pastures. Not sure if it will do any good this time of year though.....don't have the label here in front of me.

    I agree with HLC. I've used Manor in application involving behiagrass, crabgrass and goosegrass in Centipede and St Augistine tufs. I've never used Ally. As stated, Manor works like a charm.

    I looked at labels for Ally and it didn't list Dallis grass as controlled. I also looked at the Drive label as suggested by some others. It didn't list Dallis Grass either. The grasses I have dallis grass problems in is mainly bermuda, so MSMA works, but you have to hit it hard and it yellows it a lot. If anyone else has suggestions, I would love to hear them.

    In bermuda, go with MSMA with applications about 2 weeks apart. My choice is the wettable powder formulation ( I seem to get a lot more bang for the buck) and add a little liquid soad, or some other sticker, to your solution as a sticker. I use Manor in St Augestine and Centipede because they won't tolerate MSMA. In my opinion, you may possibly equal MSMA for dallisgrass, but you won't beat it.
