0 a small aircraft used for covering crops with chemicals in order to kill harmful insects and diseases:
General aviation aircraft range from single-seat crop dusters to Boeing business jets that are as big as 737s.
Crop dusters dip and dive and fly just above the ground, leaving signatures in chemicals over fields and orchards.
Although crop dusters are occasionally scorned by environmentalists, they also fertilize and plant crops from the air, in addition to spraying pesticides.
The town has taken the unusual step of hiring a crop duster to spray lagoons and waste-water treatment plants against mosquitoes.
