Research Looks at Automating Weed Killing Function

Aug. 9, 2018

A research team at the University of Arizona has developed a precision spray assembly capable of delivering herbicides at the centimeter level of accuracy with minimal off-target spray at travel speeds of 2 miles per hour.

Killing weeds with technology may soon get easier.

Mark Siemens, associate specialist and professor at the Department of Biosystems Engineering at the University of Arizona, said the university is part of a multistate effort that aims to create a precision weeding machine.

The research effort began about three-and-a-half years ago, and a large part of the automated weeding research was spent trying to address and solve the problem of being able to differentiate between the crop plants and a weed, Siemens said.

Since the project began, there have been big advancements in artificial intelligence ... that provide computers the ability to recognize different objects within an image.
