Let me be sure of this before I go saying it. Weed control does have an effect on the turfgrass when applied to it, just not enough when used in correct amounts to kill it. Right? I'm trying to make a case for spot treatment. I can't justify blanket apps of weed control on a clean lawn that I've got growing well with granular slow release ferts. My logic is while weed control in a blanket application wont kill desirable turfgrass, it doesn't help it grow, i.e. it will stunt or reduce the health. Am I correct in this statement.
