I have a lawn where the Dallis grass is up already. Is it ok to spray Bermuda with MSMA this time of year for the Dallis Grass? I am in north Alabama. Temps are now around 75-80 degrees F during the day and 50-65 degrees F during the night. Also, will there be less injury to the Bermuda in this temperature range? In the hot summer I get a lot of burning with the MSMA. I usually spray at a rate of 1.5 oz/gal with non-ionic surfactant for spot spraying. One other thing. There is some fescue or annual rye mixed with some of this Bermuda that I would like to disappear. Might the MSMA kill the fescue or rye or weaken it so the Bermuda would take over.
