Herbicide Evaluation Program

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.
