Product Overview

Prime Source Triad QC Select offers a powerful formula to provide effective post-emergent control of a wide range of broadleaf and grassy weeds in commercial and residential turfgrasses. This group 4 herbicide features a unique blend of three active ingredients: 2-4, D, Quinclorac, and Dicamba to help get rid of hard-to-control weeds like dandelion, chickweed, black medic, knotweed, plantain, oxalis, clover, cocklebur, thistle, henbit, plantain, spurge, and more. It is ideal for late season application for areas that were not able to get pre-emergent treatment in the spring. The inclusion of Quinclorac makes it efficient in controlling grassy weeds such as barnyardgrass, foxtail, and signalgrass which is absorbed through the roots and foliage. It also works excellent on crabgrass, from newly germinated 1 to 2 leaf, to 1-tiller, as well as to matured 5-tiller crabgrass or more. This liquid concentrate can be applied as a broadcast spray or as a spot application. It is labeled for use on lawns, parks, roadsides, athletic fields, sod farms, and golf course turf except on tees, greens, and collars.
Note: Due to California state restrictions, this product cannot be sold to California residents.
