Should I use a surfactant with Crossbow when folia spraying autumn olive
Yes, we would highly recommend to mix in a surfactant with Crossbow Herbicide (although it is not required for most Crossbow applications). Our most popular is Southern Ag Nonionic Surfactant. The Crossbow product label does not list autumn olive specifically, although it does list russian olive, which is similar. Autumn olive can be very difficult to control, so you will likey need to use a combination of mechanical and chemical means for treatment. This article from the Michigan Department of Natural Resources contains more information about this invasive species.
