An aquatic control sleeve apparatus for enabling application of chemical agents to underwater aquatic vegetation accumulating in a body of flowing water and a method for enabling application of the same. The aquatic control sleeve apparatus has an aquatic control sleeve placeable within a body of flowing water substantially parallel to its normal flow path. A first collar attached to the upstream end of the aquatic control sleeve funnels the entire flow of water into the aquatic control sleeve. The water surrounding the aquatic control sleeve is stilled or pacified by the funnelling of the moving water into the aquatic control sleeve, thus permitting the application of chemical agents to the stilled water to treat underwater vegetation without the fear of the chemical agents being swept away by the water current. A second collar is provided at the downstream end of the aquatic control sleeve and discharges the water funnelled through the aquatic control sleeve. The second collar prevents a backwash which would disturb the stillness of the water on the outside of the aquatic control sleeve. In an alternative embodiment, an inflatable bladder assembly is provided which fits into the mouth of an underwater spring. The bladder assembly directs the water flowing from the underwater spring into the aquatic control sleeve. A method for permitting the application of chemical agents to the underwater aquatic vegetation is also provided.
