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.
