    I live in North Alabama and I'm having a problem with dallisgrass in my common bermuda. I sprayed MSMA but it only turned it yellow, never killed it. The dallisgrass has actually turned backed to green. What can I get that will kill it?

    Dallisgrass is a booger and very hard to kill. You will need to treat the dallisgrass at least three times at 5-10 day intervals in order to finish it off. I use a rate of 1 oz per 1000ft2. Hope this helps you out.

    I use revolver and msma combined and it works very well.

    Alaturf,

    We usually start throwing in Revolver when the temps. start coming down in the fall when MSMA activity drops. Have you been using Revolver and MSMA during the summer with good results? What rate of Revolver are you using? We used it up until the middle of June but I could not tell a difference from using MSMA alone. Anything to better battle dallisgrass I would love to get your input. Thanks.

    Revolver or Triplet sf works good

    I've been using revolver w/msma all summer with good results. I usually use 1-1.5 oz per k but i only use the high side when i'm on a well irrigated lawn. I will also add iron to help offset any yellowing if needed. I've also read on here about mixing certainty and msma but i have not tried that yet.

    Thanks for the info. I may have to do some more experimenting with the Revolver and MSMA together. I have not tried Certainty and MSMA together for dallisgrass but Tim Murphy at Georgia told me they have seen no activity from using Certainty. I was asking what our alternatives would be once MSMA is phased out over the next few years and he told me a shovel would be the best option.

    Keep up the MSMA on a weekly basis and it'll be gone by the end of the month. If you delay the subsequent applications and let the plant turn back green, you have wasted your time.

    Go out there on a 90F day with msma and add some soap and it will take it out...obviously keep irrigation off for a couple days.
