I have dug up quack grass in rows between my Raspberries & have exposed the rhizomes of the Quack grass that is in the Raspberries for about one foot of their length will this produce kill the quack grass by spraying it on the exposed rhizomes. Also send an in-stock date, thank you.
Prime Source Quinclorac 75 DF Select Herbicide is not specifically labeled to target quack grass therefore cannot be recommended. Grass Out Max (Clethodim) would be an alternative herbicide to control quackgrass and other grassy weeds when tank mixed with a Crop Oil Surfactant that is safe for raspberries as well as many other vegetables, fruits, and crops. Please view the full product label for more information.
