An aquatic material application system is configured to disperse material on vegetation beneath water. The aquatic material application system includes a vessel that is configured to float upon the water. A propulsion system is attached to the vessel and configured to propel the vessel through the water. A cooling system is attached to the vessel and configured to pump the material, cool the material creating a cooled material and then dispense the cooled material from the vessel. The cooled material is configured to sink through the water to contact the vegetation.
