Phragmites are the primary invasive species target of Chesterfield Township. Phragmites create a major hindrance to our waterways: Reducing flow capacity to many of our drains, reducing visibility of the beautiful views of our lakes and streams, and limiting access for recreation by choking off our drains and streams. Phragmites are also limiting visibility along roadways, making unsafe conditions for drivers. Flooding and cutting in combination with multi-year herbicide applications can control Phragmites.
What can be done to control Phragmites?
• Prevention: Use clean equipment, free of the potential seeds which take root and expand quickly • Early Detection: Know how to identify this invasive species.
• Rapid Response: Begin mitigation the first season they are found.
The best method of controlling Phragmites without the use of chemicals and herbicides is to drown the plant by the repeated cutting of stems below the waterline. It is best to cut it when the phragmites reach four feet or more above the waterline, and by cutting the stems as low as possible below the waterline.
The best method of controlling Phragmites without flooding, is achieved with a multi-year plan of cutting in combination with herbicide and surfactant applied Mid-August through September.
