Bulrush (scripus) is an emersed, perennial, grass-like weed that grows in shallow water. Bulrush grows up to 10 feet tall in colonies from rhizomes. A leafless stem can be triangular or round and comes to a point at the tip. Loose clusters of brown flowers and seeds gather just below the tip. There is no known biological control option.
Control methods:
1) Weed raking and weed cutting is an option for seed and root reduction. This method can be difficult because new weeds can sprout from seeds and root fragments left behind.
2) Aquacide Pellets are a systemic aquatic herbicide that is best applied early spring as new growth begins to appear. Repeat treatment 3-5 weeks after the first application may be needed to kill the entire root system.
3) Aqua Neat Liquid and Shore-Klear Liquid are a second systemic option best applied mid-season when all the weeds are above the water surface and in full bloom. Again, repeat treatment 3-5 weeks after the first application may be needed to kill the entire root system.
