PROBLEM TO BE SOLVED: To provide a chemical-spraying device for tea gardens capable of increasing a control effect while suppressing the quality of a chemical used. SOLUTION: This chemical-spraying device for tea gardens is equipped with a first cover member 11 having a vent hole 11a and a first nozzle pipe 12 attached to the interior of the first cover member 11. Scattering of the chemical from the first nozzle pipe 12 is prevented by the first cover member 11. The chemical can surely be fed into the interior of a tea tree 51 by making air flow from the vent hole 11a into the interior of the first cover member 11 and generating airflow.
