SPRAY SUPERVISOR

Spray Planning

• Coordinate with the farm manager to determine spray requirements.
• Develop and implement spray schedules based on crop growth stages, pest and disease pressure, and weather conditions as provided by the farm manager.

Chemical Management

• Ensure the correct selection, mixing, and application rates of agrochemicals.
• Maintain an up-to-date inventory of chemicals and monitor stock levels.
• Store chemicals safely according to regulations and manufacturer guidelines.

Equipment Supervision

• Oversee calibration, maintenance, and repair of sprayers and related equipment.
• Ensure spray equipment is functioning efficiently to achieve accurate coverage.

Team Management
