What do we do? We evaluate new herbicide products, application timings, and efficacy for controlling an array of weed species of interest to Wisconsin farmers.

The herbicide evaluation trials use a randomized complete block design and replicate each treatment at least four times. This is different from a demonstration plot that only shows the weed control for a single instance of that particular treatment. Replication allows a researcher to observe the variability for that treatment across a field site.

During the Pest Management Field Day, at Arlington Agricultural Research Station, we showcase several of our herbicide evaluation trials to the public and provide a book describing all of our trials for the season.

At the end of the season, we compile and analyze all of the data and publish a report book in January. This year’s WCWS research report is available below.
