ABSTRACT:
A selective spraying weed control system utilizes weed detectors that identify weeds in a field of view and releases herbicide from individual nozzles. The timing of the release of herbicide from each nozzle is controlled to correspond to the actual ground speed of each nozzle. Such actual ground speed is extrapolated from direct measurements of ground speed taken from two separate locations in the weed spraying apparatus, and from the location of each nozzle within the apparatus.
