The bushy pondweed is abundant throughout Mississippi in ponds, lakes, and slow-moving streams. Generally, it is found in alkaline waters but it can tolerate a wide range of chemical and physical factors. Where found, Najas becomes abundant in shallow water, forming dense mats. It can cause severe problems in commercial and sportfishing ponds. You can control bushy pondweed with any of the chemicals listed. Be sure to read and follow label instructions before using any chemical in water.
