Will Drexel Diuron 4L Herbicide kill yellow flag iris?


Drexel Diuron 4L Herbicide is not labeled for yellow flag iris, so we cannot say for sure that it would kill it.  Unfortunately, we are not aware of a product we carry that is labeled for yellow flag iris.  You may want to contact your local cooperative extension office to see what they would recommend.
