The spraying skill of the worker was evaluated by deposition index of the water sensitive paper. We compared the amounts of deposit when 6 workers sprayed by power sprayer. The eggplant model, made by suppor pipes was used for this investigation. The results were following;1) Only some workers can stain the water sensitive paper as target on eggplant model, following exposure to the spray.2) When the height of eggplant model was 2m, the deposition index was lower than the case of 1.2m or 1.6m.3) Spraying skill was different among workers and the difference was due to their experience of spray.4) Teaching from workers who have been experienced spraying the improvement of spraying movement for few experience one made the deposition index higher.
