"Duster" (plane spraying insecticide) over a field of beans. The mechanic in the foreground indicates the outside limit of the last "swath" which has settled by the time the plane returns. Note how low the plane flies. Bean fields like this, hundreds of acres in extent, are plowed, planted, cultivated, and even harvested by tractors.
