Cade Hayden is a Master’s student in Dr. Bryan Young’s lab studying dicamba volatilization and the effects of auxin herbicide off-target movement on sensitive soybean. The first objective of Cade’s research is to quantify the volatilization of dicamba in a controlled environment. This research will isolate individual application factors to determine their impact on dicamba volatilization. The second objective of Cade’s research is to evaluate the response of dicamba-resistant soybean to low doses of 2,4-D as a tank contaminant when applied with a full rate of dicamba. This research will determine if additional soybean injury and yield reduction can be expected when 2,4-D tank contamination occurs in a dicamba application. Cade’s final research objective is to evaluate the interaction of various postemergence herbicide programs with low-dose dicamba exposure on soybean varieties sensitive to dicamba. The results of these studies will provide soybean growers with more information regarding unintended exposure of auxin-sensitive soybeans to auxin herbicides and the potential impact on yield and profitability.
Expected graduation: August 2019.
