The Iowa Learning Farms conservation webinar taking place June 30 at 12 p.m. will feature Bob Hartzler, emeritus professor/extension weed specialist at Iowa State University (ISU). In his presentation, “Weed Management in Iowa: 40 Years of Progress?”, Hartzler will discuss the herbicidal-based approach to weed management that has been employed over the past 40 years. Hartzler has been recognized for his research that focused on identifying traits of agronomic weeds that contribute to their success, and developing management programs based on weaknesses of the weeds.
Hartzler will discuss the changes in weeds and the tools used to control them over the course of his career. He noted that since the mid-1970s, weed management has relied on the continuous introduction of new chemicals to account for weed adaptation.
“The pace of weed evolution is greater than that of herbicide discovery,” said Hartzler. “We cannot continue down the same path currently used to manage weeds.”
Participants in Iowa Learning Farms Conservation Webinars are encouraged to ask questions of the presenters. People from all backgrounds and areas of interest are encouraged to join.
