I have more crabgrass this year than I ever had before. I used L pre-m. I do see a difference on a few select lawns that I used Dimension on. We have had record rain fall here this year, the boys at L say that is why. 2 years ago they blamed it on the drought. I used Team-Pro last year & was happy with the control. The boys lured me back over to Pre-m this year. The particle size was big this year, some times it appeared I was spreading gravel!!! Anyone else see excessive crabgrass?
