Abstract: A spray system includes a spray boom attached to an agricultural vehicle. The spray boom including image sensors, first spray nozzles, and second spray nozzles. The first spray nozzles are fluidly coupled to a first fluid line that holds a first herbicide mixture that includes at least one residual herbicide. The second spray nozzles are fluidly coupled to a second fluid line that holds a second herbicide mixture that includes the at one residual herbicide and at least one non-residual herbicide. The spray areas of the first and second spray nozzles are at least partially spatially aligned with one another. Agricultural field regions where weeds are not detected are exclusively sprayed with the first herbicide mixture. Agricultural field regions where weeds are detected are exclusively sprayed with the second herbicide mixture.

Abstract: A system for spot or band spraying of a treatment applied to target areas includes nozzle units that are connected to a liquid conducting member and spaced at horizontal intervals. Each nozzle unit includes first and second nozzles configured to spray droplets around opposing spraying vectors. For each target area, a spraying vector of a first nozzle of a first nozzle unit crosses a spraying vector of a second nozzle of an adjacent second nozzle unit. When a boom is at an operation height, each location within a target area receives a predefined cumulative volume of treatment, and spray patterns of the first and second nozzles of adjacent nozzle units overlap by at least 10%. When the boom is within 5% deviation from the predetermined operation height, each location within the target area receives a predefined minimum percentage of the predefined cumulative value of the treatment.
