To provide a spray controller for a chemical spraying vehicle vertically movably including right and left booms, allowing burden reduction on a worker accompanying spray resumption after a machine body turn when spraying a chemical.
The chemical spraying vehicle transferring to an adjacent area by a turn travel from a linear spray travel and starting a linear spray travel to the opposite direction vertically movably includes the right and left chemical-spraying booms (9b, 9b), and the positions of the right and left booms (9b, 9b) can be changed over between work positions for low position spray and non-work positions for high position shunting. This spray controller for the chemical spraying vehicle is provided with control processing of performing changeover control of the boom (9b) on a turn outer side to the non-work position by the first steering angle detection not less than a prescribed turn decision steering angle during the linear spray travel, deciding a turn end by the succeeding second steering angle detection not less than the turn decision steering angle on the same side, and changing over the boom (9b) to the work position by the decision of the turn end.
