Wondering what really happens when you see this in a field? This is a field sprayer.
Field sprayers are machines that apply liquid products such as herbicides, fungicides or insecticides across crop fields through a boom fitted with many spray nozzles. They can be self‑propelled or pulled behind a tractor, and are designed to deliver a specific spray rate per acre, with controls for pressure, speed and nozzle type.
You will see this equipment on farms growing corn, soybeans, canola, wheat, barley, oats, pulses and other crops across Canada, particularly in late spring and summer when weeds and diseases are most active. Many sprayers now use GPS guidance and sectional or individual nozzle control to reduce overlap, as well as options like low‑drift nozzles and boom height control to keep spray where it is intended.
Sprayers give farmers a tool to protect crop health and yield when needed, while following label directions and environmental protection measures set by regulators.
