[ Scirpus spp ]

Bulrush (Scirpus spp) is a common emergent plant found throughout the United States. Found in marshes and shallow shorelines. Stems are long and thin shaped triangular or round. Cluster of browinish flowers and seeds are located at the end of the stem. Bulrush provides excellent fish habitat and helps stabilize shoreline sediments. When Bulrush growth inhibits lake access we recommend the following solutions.

The genus has a cosmopolitan distribution, and grows in wetlands and moist soil. Some species specialize in saline, marshy, environments such as intertidal mud-flats; others prefer ponds or lake-sides and river-beds. They have grass-like leaves, and clusters of small spikelets, often brown in colour. Some species can reach a height of 3 m, while others are much smaller, only reaching 20-30 cm tall.
Q. What are the best control options?

Herbicide Application:
Navigate herbicide is an excellent choice. Its granular formulation is easy to apply. Apply at a rate of 150 Lbs to 200 Lbs per acre. A 50 foot by 50 foot area would require a maximum of twelve (12) pounds. For Bulrush the next best method is the application of a herbicide with the active ingredient called glyphosate found in brands like Rodeo™ and Shore-Klear™. Rodeo herbicide is applied directly onto the dry emergent portion of the plant. Make sure to use a surfactant with Rodeo or Shore-klear

Cutting can also be effective in small areas. See water weed cutter.

Q. When is the best time to treat?
A.Early application is recommended for Bulrush control.
Q. Do I have to treat Bulrush every year?
A.Navigate and Rodeo are systemic herbicides and longer-term control can result.
Q. How long before I see results?
A.Be patient, Bulrush is stubborn and symptoms take a week to appear and at least several more for the plant to succumb. Your patience will be rewarded!
