Tractor giant John Deere just spent $305 million to acquire a startup that makes robots capable of identifying unwanted plants, and shooting them with deadly, high-precision squirts of herbicide.
John Deere, established in 1837 to manufacture hand tools, announced it had acquired Blue River Technology.
Pesticides and other chemicals are traditionally applied blindly across a whole field or crop. Blue River’s systems are agricultural sharpshooters that direct chemicals only where they are needed.
The startup’s robots are towed behind a regular tractor like conventional spraying equipment. But they have cameras on board that use machine-learning software to distinguish between crops and weeds, and automated sprayers to target unwanted plants.
This season Blue River tested a second system for cotton farmers, ahead of a planned commercial launch in 2018. That system can target weeds with squirts of herbicide no larger than a postage stamp. Willy Pell, director of new technology at Blue River, says the system has shown it can reduce herbicide use by 90 percent.
