| It could have been the timing of your spray, or the weather when you applied the crabgrass control. You didn't identify your turfgrass type so I'm not sure what to recommend. The following products are registered for crabgrass control in Marathon lawns: Acme Crabgrass & Nutgrass Killer (MSMA) Grassy Weeds, including; Crabgrass, Dallisgrass, Goosegrass, Johnsongrass, Nutsedge, Witchgrass. Green Light Crabgrass Killer (MSMA) Grassy Weeds, including; Crabgrass, Dallisgrass, Goosegrass, Johnsongrass, Nutsedge, Witchgrass.

You'll want to apply a pre-emergent herbicide on your lawn early next spring to get a jump start on stopping any crabgrass seeds from sprouting in your lawn next summer. If you are grow a different type of turf, read the product labels to make sure both crabgrass and your turf type are both listed on the label. Best wishes with your lawn! |
