I am currently using Speedzone and very happy with it, but now the crabgrass is starting to come up in spots. Can I use Quinkill at the same time or alternate, or would that stress the grass too much?
After speaking with the manfuacturer they have advised to use the Quinkill Max Crabgrass and Weed Killer to treat the crabgrass and to rotate your application with the Speedzone to prevent resistance of the herbicide. You can mix with Pendulum 3.3 EC to create a better residual effect. It is recommended to use a surfactant when applying the product to gain better control.
