KnockDown Defense provides fast control of tough invasive weeds such as duckweed, watermeal, fanwort, hydrilla, as well as algae. KnockDown is an EPA-registered liquid herbicide that contains 42% of the active ingredient Flumioxazin. Ideal for controlling algae and submerged aquatic weeds in ponds and lakes. Effective in slow-moving or quiescent waters such as bayous, canals, drainage ditches, reservoirs, and marshes. KnockDown is versatile and breaks down quickly in water without accumulating in the sediment or clogging application sprayers. Best results when mixed with water and Treatment Booster Plus in a tank sprayer.
