The goal was to let farmers precisely target pesticide spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest problems. Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3, 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running" fevers".
