Too many preemergent herbicides can backfire by pruning the turf roots and thinning out the lawn.
Per your's and others suggestion I quit using the usual pre's. It does seem I will have to go back to using some pre on certain bermuda lawns to fight the crab. I will begin using Gallery on higher end lawns with broadleaf pressure.
Did you quit using Simazine because you felt it prunes the roots? I didn't think it was that much of a root pruner?
