Spring Herbicide Activity Progress

This is an update on corn preemergence herbicide research conducted at Rochester, MN. This video is a follow up to the video last week on: Preemergence Corn Herbicides Applied in Dry Conditions Followed by Wet and Cool Growing Conditions. We are checking-in to see how things have been progressing and will be discussing observations we have made in the past week. This year we have seen differences in the time it takes for different preemergence herbicides to activate, and differences in "reach-back" with different herbicide products. We have also seen the benefit of preemergence herbicides in taking some of the pressure off of postemergence applications by providing at least some of our weed control, and by extending the window to accomplish postemergence applications. We will be following this trial during the 2017 growing season, providing periodic video updates
