Abstract

An aquatic pesticide application system for applying at least one pesticide to a body of water from a floating vessel is disclosed. The system comprises a dispensing system for the pesticide(s), a receiver on the vessel for receiving position data from a global positioning system satellite, a storage device for storing digital map data representing a predetermined pesticide treatment plan for the body of water, and a processor for receiving position data and digital map data wherein the processor continuously outputs pesticide delivery signals derived from comparing position data and digital map data to the dispensing system to dispense pesticide(s) to the body of water when the vessel is directed over the body of water.

the processor continuously outputs navigation signals derived from comparing position data and digital map data when the vessel is directed over the body of water, and

the aquatic pesticide application system further comprises a navigation device in communication with the processor for receiving the navigation signals from the processor, the navigation device indicating deviation from the predetermined path for the vessel on the body of water based on the navigation signals received from the processor.

6. The aquatic pesticide application system of claim 1 wherein:

the aquatic pesticide application system further comprises a speed sensor in communication with the processor for providing speed signals to the processor, and

the processor derives the pesticide delivery signals from comparing position data and digital map data and the speed signals.

7. The aquatic pesticide application system of claim 1 wherein:

the aquatic pesticide application system further comprises a water depth sensor in communication with the processor for providing water depth signals to the processor, and

the processor derives the pesticide delivery signals from comparing position data and digital map data and the water depth signals.

8. The aquatic pesticide application system of claim 1 wherein:

the aquatic pesticide application system further comprises a speed sensor in communication with the processor for providing speed signals to the processor,

the aquatic pesticide application system further comprises a water depth sensor in communication with the processor for providing water depth signals to the processor, and

the processor derives the pesticide delivery signals from comparing position data and digital map data, the speed signals, and the water depth signals.

9. The aquatic pesticide application system of claim 1 wherein:

the aquatic pesticide application system further comprises a water quality sensor in communication with the processor for providing water quality signals to the processor, and

the processor derives the pesticide delivery signals from comparing position data and digital map data and the water quality signals.

10. The aquatic pesticide application system of claim 1 wherein:

the dispensing system is fixed to the vessel and delivers at least one pesticide to the surface of the body of water.

11. The aquatic pesticide application system of claim 1 wherein:

the dispensing system is fixed to the vessel and delivers at least one pesticide under the surface of the body of water.

12. The aquatic pesticide application system of claim 1 wherein:

the dispensing system is movable with respect to the vessel and delivers at least one pesticide to the surface of body of water.

13. The aquatic pesticide application system of claim 1 wherein:

the storage device or another storage device stores position data and pesticide delivery signals received from the processor when the vessel is directed over the body of water such that the application rate of each pesticide at each position can be reviewed after the vessel is directed over the body of water.

14. The aquatic pesticide application system of claim 1 wherein:

the vessel is an airboat.

15. The aquatic pesticide application system of claim 1 wherein:

at least two different pesticides are applied to the body of water.

16. The aquatic pesticide application system of claim 1 wherein:
