Diquat is an industrial weed killer to control pond weed, pond algae, and other aquatic weeds. We carry Alligare Diquat which is a generic of Reward Herbicide and much more cost effective. Diquat is a weed killer concentrate that needs to be mixed with water before application. You will not find a safer aquatic herbicide to kill pond weeds and algae.
