Evaluation of new and existing herbicides for use in corn has annually occurred in Wisconsin for over 30 years. This program continues to compare effectiveness of weed control of herbicides applied at a range of timings and rates. In many cases crop safety and yield are also evaluated. 2015 corn herbicide results are now summarized and available (see below for details).
Research was conducted at Arlington Agricultural Research Station (2 trials) and Rock County farms in Janesville Wisconsin (4 trials). Please click on the Trial ID link for a pdf of the application information and summarized results. Note that values are an average of four replications. Standard deviations are also provided as often responses (e.g. weed control, crop yield) to any treatment can vary within a trial. Consider this variability in addition to average values when comparing treatments.
