A riding sprayer in rice field has been developed for large scale paddy fields. It is inevitable that the sprayer damages the rice plant when the sprayer is driven into the paddy field. This study was conducted to determine the practical use of the sprayer in paddy field and how to drive the sprayer without the injury of rice plant.When the sprayer moved in a straight line, the proportion of injured rice plant was negligible. The proportion of injured rice plant was 3.46% in turning area (6.3m×10.8m) estimated per one time. The proportion of injured rice plant was smaller in turning area where rice plant raw run paralled to sprayer's movement compared to the run vertical to the raw. The yield of the rice plants grown near the trace of the sprayer or under the sprayer was not significantly different from other rice plants.
