Trailing Hose System for Aquatic Ecosystem Liquid and Granular Materials Application

A trailing hose system is disclosed for the application of materials (liquid or granular pesticides, nutrient inactivation, water quality improvement compounds) in a water body. The trailing hose or hoses release the material (liquid or granular pesticides, nutrient inactivation, water quality improvement compounds) at the desired depth within the water column. The current technology for the subsurface application of these materials is surface injection, granular spreaders, and the use of weighted hoses deployed from a vessel (boat). Surface injection of these materials below the thermocline, or to the bottom of a water body in sufficient concentrations to control the target pest, to deactivate nutrients, and or enhance water quality is required in the industry. The current technology that utilizes the use of weighted hose is cumbersome, and is a slow process that allows for the application of these materials at approximately 1-2 miles per hour.
