Best way to apply it?
While Rodeo is not labeled to control Yellow Flag Iris, being a glyphosate-based product it possibly could. We are unable to find any product listed to kill this plant specifically, but any glyphosate product is non-selective and would affect plants treated with it. If you are making an application with a sprayer you would use approx. 2 and 2/3 fluid oz. Rodeo per gallon water or 5 pints Rodeo per acre. Please refer to the product label for application.
