Hitting your target—and only your target—is a top priority when spraying pesticides from an airplane. And the use of a small object could be a big help in making sure that happens.
That’s the focus of the research being conducted by Daniel Martin, an engineer with Agricultural Research Service’s (ARS) Aerial Application Technology Research Unit in College Station, Texas. Martin has shown that attaching dime-sized metal clips to airplane wings—a technology known as “vortex generators”—can reduce pesticide drift.
