Yesterday while out doing maintenance accounts I noticed crabgrass in one of the nieghboring lawns. It is currently in the 2 tiller stage. I hope to finish with preemergent apps by Friday but was wondering what should I do if the crabgrass goes beyond the 3 tiller stage? Most of the lawns I do are Fescue but some are Bermuda. Drive doesn't work in my area. I was thinking of maybe adding some MSMA to the Dimension or do you have any suggestions? I know I will be dealing with this problem throughout the season as I pick up more weed control accounts and would like to know what options I have to deal with the crabgrass. I know I should have finished pre-m by mid Febuary which is the general rule around here.
