The Harrison County Pest Resistance Project will hold a field day Tuesday, July 9th. Join us from 10:00 am to 1:00 pm to observe field trials, which include both herbicide and fungicide trials, at the farm operated by Larry Buss southwest of Logan. This event is free and open to the public. The Iowa Cattlemen’s Association will be grilling lunch for participants.
Current and future management of waterhemp, marestail, giant ragweed, and Palmer amaranth is a concern for area farmers. Ten herbicide programs will be available for comparison to evaluate success and implications for resistance management. Additional agenda details follow.
