Field Events

Field Day: Tuesday, July 9, 2019, 10 am to 1 pm

Come see results of the 2019 field trials, which will include diverse herbicide systems on both till and no-till sites. A comparison of fungicide treatments is also planned. Visit the event's page for more detail. 

Location: Immediately northeast of the intersection of Niagara Trail and 262nd Street, which is about 1.5 to 2 miles southwest of downtown Logan.

Field Day: June 18, 2018

A corn weed management field day took place June 18th southwest of Modale. Participants had the opportunity to observe the progress of field trials. They could also learn how to identify Palmer amaranth, as this site was the first case of Palmer amaranth in Iowa.

Field Day: July 13, 2018

The July field day was held at a no-till soybean field southwest of Logan, again featuring ten weed management programs. These replicated treatments allowed attendees to compare differences in weed management between treatments containing residual preemergence herbicides vs. no residual, and the effects of post-emergence residual applications. A video of the field day can be viewed at https://www.youtube.com/watch?v=ydTzOFrZREY&t=7s.

EPA Tour Stop: August 2, 2018

A group of researchers and representatives from the United States Environmental Protection Agency (EPA) and the United States Department of Agriculture (USDA) heard from the Harrison County Pest Resistance Project Team regarding its efforts to share information on local weed resistance in the county. The team hosted the EPA and USDA personnel on a tour of the no-till soybean field. The Harrison team recognizes that the EPA and USDA are also part of the overall agricultural community that must be engaged to fully deal with pest resistance management.
