I live in Rochester Hills which is in Oakland County. Our subdivision has Phragmites in the common areas and we are looking for ways to treat them. Can you provide any help on how to treat, what has been done in the past, how effective it has been, where has phragmites been treated in Oakland County, concerns for not treating them and concerns for treating them related to potential health consequences. For instance I know using Glyphosate is an option but it has also been linked to some types of cancers. Thank you for your time
Rather than repeat the well documented information available on managing phragmites, it seems better to provide links to the original documents.
This first is a general article describing the invasive species: https://www.canr.msu.edu/news/invasive-phragmites-australis-learning-the-basics-msg19-gass19. The article has several links to other informative sites embedded in it, especially this one: https://www.michigan.gov/documents/deq/wrd-ais-guide-phragmites_622427_7.pdf,
MISIN (Midwest Invasive Species Information Network) also has good information, very similar to the resources listed above: http://www.misin.msu.edu/facts/detail/?project=misin&id=33&cname=Phragmites+%28Invasive%29.
As you'll note in the reading, herbicides are part of the recommended treatment protocol to manage this difficult species. It's important to read and follow all label instructions when using herbicides to minimize the risks associated with them, both to the applicator and the environment. Enlisting the aid of a certified pesticide applicator (licensed by the state) will minimize the risk.
Rochester Hills is a member of the Oakland County CISMA (Cooperative Invasive Species Management Area). You might contact this organization for information on existing management programs: https://www.michiganinvasives.org/occisma/.
