Abstract

The present disclosure provides systems and methods for inoculating a plurality of plants. In various embodiments, an exemplary method includes spraying a plurality of plants with an inoculum utilizing an automated inoculum spraying subsystem of a mobile inoculation system. The method additionally includes spraying the plurality of plants with a grit medium utilizing an automated grit blasting subsystem of the mobile inoculation system. Spraying the plants with the grit medium inflicts a plurality of wounds to the tissue of the plants on a plurality of surfaces of the plants. The wounds inflicted by the grit medium allow the inoculum to be absorbed into the plants to inoculate the plants.

Claims

1. A method for inflicting a plurality of wounds to the tissues of plants, said method comprising:

spraying a plurality of plants with a grit medium consisting essentially of particulate matter, utilizing an automated mobile plant wounding system such that the grit medium impacts the plants and inflicts a plurality of wounds to the tissue of the plants.

2. The method of claim 1, wherein spraying the plants with the grit medium comprises:

positioning at least one grit spray nozzle of the wounding system at a selected height above a ground surface from which the plants are growing;

transporting the mobile plant wounding system across the ground surface such that the plants pass beneath or adjacent the at least one grit spray nozzle; and

dispensing the grit medium from the at least one grit spray nozzle onto the plants as the plants pass beneath or adjacent the at least one grit spray nozzle.

3. The method of claim 2, wherein dispensing the grit medium from the at least one grit spray nozzle comprises dispersing the grit medium in a grit medium field of spray such that all plant surfaces exposed to the grit medium field of spray incur a substantially uniform coverage of wounding across all the exposed surfaces.

4. The method of claim 3, wherein dispersing the grit medium in a grit medium field of spray comprises spraying the grit medium in fan-like pattern from the at least one grit spray nozzle.

5. The method of claim 3, wherein dispersing the grit medium in a grit medium field of spray comprises:

spraying the grit medium from the at least one grit spray nozzle; and

oscillating the at least one grit spray nozzle in a side-to-side motion substantially orthogonal to a direction of travel of the mobile plant wounding system across the ground surface.

6. The method of claim 1 further comprising:

tracking the movement of the mobile plant wounding system along rows of plants utilizing a global positioning system of the mobile plant wounding system;

identifying the location of the mobile plant wounding system with respect to the rows of plants; and

controlling the spraying of the grit medium based on the location of the mobile plant wounding system.

7. The method of claim 1 further comprising spraying the wounded plants with an inoculum such that the inoculum is absorbed into the plants.

8. The method of claim 1 further comprising spraying the wounded plants with an inoculum comprising a pathogen such that pathogens are absorbed into the plants.

9. The method of claim 1 further comprising an least one of:

reducing the health of at least one plant as a result of the inflicted wounds;

reducing the survivability of at least one plant as a result of the inflicted wounds; and

reducing the function of at least one plant organ as a result of the inflicted wounds.

10. The method of claim 1 further comprising causing at least one plant to not recover as a result of the inflicted wounds.

11. A method for inflicting a plurality of wounds to the tissues of plants, said method comprising:

positioning at least one grit spray nozzle of an automated mobile plant wounding system at a selected height above a ground surface from which a plurality of plants are growing;

transporting the mobile plant wounding system across the ground surface such that the plants pass beneath or adjacent and the at least one grit spray nozzle; and

spraying the plants with a grit medium consisting essentially of particulate matter dispensed from the at least one grit spray nozzle as the plants pass beneath or adjacent the at least one grit spray nozzle to inflict a plurality of wounds to the tissue of a plurality of surfaces of the plants.

12. The method of claim 11, wherein dispensing the grit medium from the at least one grit spray nozzle comprises dispersing the grit medium in a grit medium field of spray such that all plant surfaces exposed to the grit medium field of spray incur a substantially uniform coverage of wounding across all the exposed surfaces.

13. The method of claim 12, wherein dispersing the grit medium in a grit medium field of spray comprises spraying the grit medium in fan-like pattern from the at least one grit spray nozzle.

14. The method of claim 12, wherein dispersing the grit medium in a grit medium field of spray comprises:

spraying the grit medium from the at least one grit spray nozzle; and

oscillating the at least one grit spray nozzle in a side-to-side motion substantially orthogonal to a direction of travel of the mobile plant wounding system across the ground surface.

15. The method of claim 11 further comprising:

tracking the movement of the mobile plant wounding system along rows of plants utilizing a global positioning system of the mobile plant wounding system;

identifying the location of the mobile plant wounding system with respect to the rows of plants; and

controlling the spraying of the grit medium based on the location of the mobile plant wounding system.

16. An automated mobile plant wounding system for inflicting a plurality of wounds to the tissues of plants, said system comprising:

a chassis frame connectable to a mobile platform;

a plurality of wheels rotatably connected to the chassis frame such that the mobile plant wounding system can be transported across a ground surface from which a plurality of plants are growing; and

a grit blasting subsystem mounted to the chassis frame, the grit blasting subsystem including at least one grit spray nozzle that is positionable at a selected height above the ground surface and at a location such that plants pass beneath or adjacent the at least one grit spray nozzle when the mobile plant wounding system is transported across the ground surface, the grit blasting subsystem structured and operable to spray the plants, as the plants pass beneath or adjacent the at least one grit spray nozzle when the mobile plant wounding system is transported across the ground surface, with a grit medium consisting essentially of particulate matter dispensed from the at least one grit spray nozzle to inflict a plurality of wounds to the tissue of a plurality of surfaces of the plants.

17. The system of claim 16, wherein the grit blasting subsystem comprises a compressor assembly structured and operable to dispense the grit medium from the at least one grit spray nozzle at a velocity sufficient to create the wounds to the plant tissue.

18. The system of claim 17, wherein each of the at least one grit spray nozzles comprises a grit spray nozzle tip structured and operable to disperse the grit medium such that the grit spraying subsystem dispenses the grit medium in a grit medium field of spray that inflicts a substantially uniform coverage of wounding across all plant surfaces exposed to the grit medium field of spray.

19. The system of claim 17, wherein each of the at least one grit spray nozzles comprises a grit spray nozzle tip structured and operable to disperse the grit, and the grit spraying subsystem further includes a motor structured and operable to oscillate the at least one grit spray nozzle in a side-to-side motion such that the grit spraying subsystem dispenses the grit medium in a grit medium field of spray that inflicts a substantially uniform coverage of wounding across all plant surfaces exposed to the grit medium field of spray.

20. The system of claim 16 further comprising an inoculum spraying subsystem mounted to the chassis frame, the inoculum spraying system including at least one inoculum spray nozzle that is positionable at a selected height above the ground surface and at a location such that the plants pass beneath or adjacent to the at least one inoculum spray nozzle when the mobile inoculation system is transported across the ground surface, the inoculum spraying subsystem structured and operable to spray the plants, as the plants pass beneath or adjacent to the at least one inoculum spray nozzle when the mobile inoculation system is transported across the ground surface, with an inoculum dispensed from the at least one inoculum spray nozzle, whereby the inoculum is absorbed into the plants via the inflicted wounds.
