Will Monterey Spurge Power kill Iris that it has invaded?


Monterey Spurge Power is used only as directed to turf lawns. Per the Monterey Spurge Power label: Avoid drift of spray mist to vegetables, flowers, ornamental plants, shrubs, trees and other desirable plants.  It could injure iris if contact is made but not completely kill it.

If you are looking to get rid of wild Iris, we recommend Quali-Pro MSM Turf Herbicide on listed turfs.
The usage rates for Quali-Pro MSM Turf Herbicide will vary depending on what type(s) of weeds you are treating for, what type of grass you have, whether you will be spot treating or broadcast spraying, and how much area you need to cover.  Please refer to the product label for complete application instructions.
