Dallisgrass is extremely hard to control. It is not controlled very well with any over the counter products. MSMA used to be available for Dallisgrass control, but not any more. The EPA restricted its used a few years ago, and it is not available any longer to anyone for residential Dallisgrass control.
The best thing I can recommend for Dallisgrass control is to either 1) Use Certainty to suppress the Dallisgrass 2) Use RoundUp for spot control and for suppression 3) Use Monument for Suppression 4) Dig it up.
Unfortunately, there are not a lot of answers for Dallisgrass available to unlicensed persons. Even if you had a license, control can be very difficult.
Hope this helps.
