WOODY ORNAMENTALS SHRUBS, VINES, AND TREES
Quali-Pro Oxadiazon 2G is a selective, pre-emergent herbicide for control of annual grasses and many broadleaf weeds in commercial turf and on a wide variety of woody ornamental shrubs, vines, and trees. Quali-Pro Oxadiazon 2G controls weeds by killing the young weed seedlings as they come in contact with the herbicide during germination.
For best results, water-in the product as soon as practical after application.
10-10-10 fertilizer with secondary micronutrients is the carrier for the herbicide. Nutrients will be supplied according to the rates applied, but they are inert to the herbicide and its activity.
