A crop duster is an aircraft specifically designed for agricultural purposes, primarily to spray pesticides, herbicides, and fertilizers over large fields. These planes help farmers protect their crops from pests and diseases, ensuring better yields. Crop dusting is often done from low altitudes, allowing for precise application of chemicals. The process of crop dusting involves flying over farmland and releasing the substances in a controlled manner. This method is efficient and can cover vast areas quickly compared to traditional ground spraying. Pilots who operate crop dusters must be skilled in flying and familiar with agricultural practices to ensure safety and effectiveness.
