Dealing with weed escapes in non-GMO or “identity preserved” soybeans can be challenging because many of the herbicides available don’t control a large spectrum of weeds nor will the handle larger weeds the way that glyphosate does in a glyphosate tolerant (RR) soybean crop.
I have summarized the performance of several post-emergence herbicides for non-GMO soybeans based on University of Guelph research and I have also included the label statements around application timing and weed species listed as “controlled”.
