The boom system allows for multi-direction section activation control, allowing left-to-right and right-to-left deactivation, left-to-right and right-to-left activation, and piecemeal or discontinuous deactivation and activation of each section independent of other sections. A first set of deactivation/activation buttons may be arranged at a joystick grip and allow for left-to-right deactivation and right-to-left activation of sections. A second set of spray deactivation/activation buttons may be arranged at the joystick grip and allow for right-to-left deactivation and left-to-right activation of sections. A third set of spray deactivation/activation buttons may be arranged at a touchscreen and allow for individual deactivation/activation independent of position of the sections with respect to the boom and each other.
