Claim of US Patent No. 10,765,102

1. An invasive species toxin application system comprising:a boat including a propulsion system for moving the boat along a surface of a body of water in a propulsion direction as directed by a steering wheel;
a tank supported by the boat for holding a toxin;
a nozzle extending perpendicular to the propulsion direction;
nozzle supports extending downward from the boat to hold the nozzle beneath the surface of the body of water at a predetermined depth; and
a pump for delivering the toxin from the tank to the nozzle at a predetermined delivery rate;
wherein the nozzle provides at least one laterally extending opening presenting a variable fluid flow resistance as a function of lateral distance to promote uniform flow rate as a function of lateral distance.
