It acts as a dual-threat solution by killing over 50 types of weeds—including morningglory and plantain—while simultaneously fertilizing the soil to thicken your lawn.

It is highly versatile, working effectively on everything from Bluegrass and Fescue to Bermuda and Zoysia. Covering up to 12,000 sq. ft., it is a heavy-duty way to crowd out future weeds and reclaim your curb appeal.
