Over the spray operators right shoulder

A view from the drivers seat of a crop sprayer when looking back to see the spray boom and spray being evenly applied across the width of the machine. The view to the left should be relatively the same. The yellowish spray is a pre emergent herbicide that should allow the Wheat plant to grow but disrupt the germination of the black grass and wild oat weed seeds that need to be controlled.
