    • PROBLEM TO BE SOLVED: To provide common use of a chemical sprayer for a rice transplanter having a different number of seedling planted rows and suppress the cost increase therefor as much as possible. SOLUTION: The chemical sprayer 7 for diffusing and spraying a chemical with a diffusion mechanism is composed by mounting thereof on a seedling planting apparatus of the rice transplanter. The chemical sprayer 7 is freely mountable through an intermediate member 46 mountable by turning upside down on the seedling planting apparatus. The mounting height of the chemical sprayer 7 can be changed in a plurality of stages by turning the intermediate member 46 upside down and mounting thereof. Furthermore, the diffusion mechanism is provided with rotating blades for diffusing the chemical. The mounting height of the chemical sprayer 7 and the spraying width of the chemical sprayed from the chemical sprayer 7 can be changed into the plurality of stages according to the number of seedling planted rows with the seedling planting apparatus by selecting the rotation blades from a plurality of kinds for use or changing the number of revolutions of the rotation blades into the plurality of stages.
