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
