Automated Thinner and Weeder Technologies Round-Up Field Day Event

Since last season, there have been several new developments in commercial automated thinning and weeding technologies. Companies that focused primarily on weeding have developed new algorithms and/or improved precision so that the machines can now also be used for thinning lettuce. Significant enhancements have also been made to existing lettuce thinning machines including improved speed, durability and the ability to spot spray inter-row weeds. Arizona Cooperative Extension is in the process of organizing the Automated Thinner and Weeder Technologies Roundup, a field day where these technologies will be demonstrated operating in the field. NEW for this year will be that demos will be at the field scale level (> 1 acre) so attendees will have the opportunity to more fully evaluate machine performance and have time to visit with company representatives. The event will be held November 13th at the Yuma Agricultural Center in tandem with the Desert Difference Ag Connect Event. We would like to showcase as many innovative technologies as possible, so please contact me if you are interested in demoing your thinner/weeder or know someone that is. It’s an open invitation - private companies, university and government researchers are all welcome!
