I sprayed 6 oz. per gallon on the catails in my pond and was wondering how long should it take before I start to see them dying back?
If you review the ERASER AQ LABEL, you’ll note it takes at least one week for them to show any signs of the treatment. And since cattails are mostly tan to brown naturally, it might take even longer for you to see for sure. I would wait two weeks before I attempted to remove them just to be sure the ERASER AQ has had plenty of time to take effect.
