PURPOSE:To enable sure application of an agent to objective bud, by placing plural nozzles along the circumferential part of a nozzle plate of a spray head attached to the tip of an ejection pipe, inclining the nozzle directions in a manner to converge at a front position of the nozzle plate and spraying an agent to the circumference of a trunk using the above nozzle. CONSTITUTION:A spray head 1 attached to the tip of an ejection pipe 2 is provided with a nozzle plate 3 having plural nozzle openings 4 arranged at the circumference of the nozzle plate 3. The plural nozzles 4, 4... are inclined in such a manner as to converge the opening directions at a position in front of the nozzle plate 3. The spraying direction of the agent can be accurately defined and the adhesion of the agent to leaves can be prevented.
