Basis of Selectivity	None
Application Methods	Postemergence. Apply when weeds are visible and are actively growing. It can be applied: with a boat bailer device that injects the chemical below the water surface; sprayed over the water surface; or poured directly from a container onto the surface.
Residual Activity	Quickly inactivated by adsorption to soil particles.
Unique Characteristics	Must be used with and applied on non-turbid water, as the soil particles in muddy water drastically reduce the effectiveness of the material. Do not use treated water for swimming or consumption by humans or animals for at least 24 hr. Do not use water for irrigation for 5 days after treatment. To avoid fish kills caused by oxygen depletion, treat only 1/4-1/3 of the area at a time. Avoid application or drift onto crops, lawns, grazing areas, ornamental plants and other desirable plants.
