Prashant Jha, associate professor and extension weed specialist with ISU Extension and Outreach, will give an introductory talk and hand out copies of the field book explaining the different trials being conducted in 2019.

Jha said the major resistant weeds of concern in Iowa are waterhemp, giant ragweed and marestail. Members of the Iowa State Weed Science Program will be available to help answer producer questions and explain current research.

“We’ll be there in case there are some specific questions,” Jha said. “We will have some of the new herbicide technology updates and weed management information, including pre-emergence and post-emergence.”

The field day begins with on-site registration at 8:30 a.m., and there will be a brief overview at 9 a.m. The program will last until about noon.

The Curtiss Farm is located at 2219 520th Ave., Ames. For more information, contact Prashant Jha at 515-294-7028, or pjha@iastate.edu.
