  • Publication number: 20200141079
    Abstract: A weed control apparatus for a vehicle includes a processing unit that receives at least one image of an environment. The processing unit analyses the at least one image to activate at least one chemical spray unit. A liquid weed control chemical is atomized and charged by the at least one chemical spray unit. The at least one chemical spray unit has at least one part configured to be held at high voltage with respect to zero volts potential. The at least one high voltage power supply and the at least one chemical spray unit are configured to hold the at least one part of the at least one chemical spray unit at one or a number of high voltages with respect to zero volts potential, such that the atomized liquid weed control chemical is electrically charged.
