PROBLEM TO BE SOLVED: To provide a sprayer which facilitates spraying a liquid material, e.g. a chemical, in the form of bubbles in a field. SOLUTION: One or more chemical foam generating sections A are arranged in the front portion of the sprayer; a blower 15 connected to the chemical foam generating sections A is arranged in the rear portion of the sprayer; and an air flow control valve 27 is disposed in a blowing pipe 14 arranged between the chemical foam generating sections A and the blower 15, resulting in good balance between the front and rear portions of the sprayer. Because a manual operation lever 29 for the air flow control valve 27 is arranged close to the operator's seat 7, the operator being seated on the operator's seat 7 can easily control the air flow in spraying a chemical.
