Herbicide Control of Bulrush

Herbicide control is a great option for Bulrush because you can literally apply the herbicide and then sit back and let it do its work. Most herbicides can control Bulrush throughout the season and only needs to be applied once a year.

Herbicide Products To Control Bulrush 

Rodeo Herbicide-          Rodeo Herbicide

Rodeo herbicide is extremely effective at killing Bulrush at their roots and preventing them from coming back for years. Its active ingredient is Glyphosate† N-(phosphonomethyl) glycine, isopropylamine salt which has shown to be practically not-toxic to freshwater invertebrates.

After applying Rodeo herbicide you should start to see results within 2 to 4 days and within 7 to 10 days your Bulrush problem should disappear. However, you want to make sure there is no rain in sight for 6 hours after applying for maximum results.
