Prime Source Quinclorac 1.5L Select Herbicide is a selective, post-emergent herbicide that can be safely applied to many types of turf to control a variety of broadleaf and grassy weeds. Roundup QuikPRO is a non-selective post-emergent herbicide that will kill anything it is applied to. This formulation of RoundUp has two active ingredients: 73.3% glyphosate and 2.9% diquat. The addition of diquat, along with the surfactant, gives you even faster burndown. It controls broadleaf and grass weeds, or woody brush and trees - roots and all. If you are wanting to kill everything, RoundUp QuickPro would be the product to use over Quinclorac.
