Expert Response

Please refer to for positive identification.  Once identified, the Management Options tab will give you chemical recommendations, mechanical control options, and ways to manage that plants growth.

Remember that if using chemical control, only treat 1/4 to 1/3 of the pond at a time at a 2 week (or longer if the product label states) to allow decomposition before treating any more of the weed.  Failure to do so can cause a drop in saturated oxygen resulting in fish kills.
