I have about 1/2 acre of area to treat around my shoreline in a 50 acre lake. Will this product work for submerged, rooted weeds? If so, how much do you recommend and how to apply?
Diquat Water Weed and Landscape Herbicide should be applied at a rate of 1 to 2 gallons per surface area of water. For a 1 acre lake or pond - spray 1 to 2 gallons of Diquat into the lake. If using a hand sprayer, for example, 2 gallon sprayer, put 1 gallon of water and 1 gallon of Diquat into the sprayer and spray the contents over an acre of the area. Per the product label, it should be applied in the spring or early summer when the weeds are actively growing and when water temperatures have reached or exceeded 50 degrees.
