Precision technology for weeds is helping to reduce labor and inputs. 

Michigan State University’s Dan Brainard tells Brownfield many specialty crop growers are searching for automated technologies to replace increasingly expensive and difficult-to-find labor.

“The conventional growers are using smart sprayers but the organic or those who have fewer herbicide options are using smart weeders, which are distinguishing the crop from the weeds and shooting these blades between,” he explains.

When compared to new equipment, Brainard says sometimes basic machines are just as effective.

“Don’t get too enamored with the robotics and the automation before you have everything else straight,” he recommends.

His research lab is currently studying autonomous weeders from Europe for their accuracy and cost benefits for growers.

Brownfield interviewed Brainard during this week’s Midwest Mechanical Weed Control Field Day in Benton Harbor, Michigan.
