Ferti-Lome Weed-Out Broadleaf Weed Control will not control wild violets. We recommend using a liquid post-emergent herbicide for this weed since it can be very tough to control. Fertilome Weed Free Zone can be used on ryegrass to control wild violet. You could also use a product with quinclorac, such as Solitare Herbicide.
