Cade Hayden is a M.S. student in Dr. Bryan Young’s lab studying the effects of tank contamination with auxin herbicides. The main goal of Cade’s research is to examine the effects of both dicamba and 2,4-D herbicides on Roundup Ready 2 Xtend and Roundup Ready 2 Yield soybeans. The response of the treatments will be will be characterized by observing the growth, development, and yield of the soybeans. The effects that herbicide rate, herbicide combinations, and soybean growth stage have on injury will also be determined. The interaction between these herbicides and varieties will be characterized to provide soybean growers with more information on how unintended exposure will impact yield and profitability.
