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.
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.
