The latest wave of herbicide-resistant soybean varieties will play a crucial role this year in managing the Mid-Atlanticâs toughest weeds.
As marestail and Palmer amaranth have developed defenses against glyphosate and other common herbicides, seed and chemical companies have rolled out bean varieties that tolerate the sprays â like 2,4-D, dicamba and glufosinate âthat still work.
Indeed, those three herbicides are about the only ones left that will kill post-emergence marestail.
âOur sort of conventional herbicides that are labeled across all types of soybeans just wonât control them anymore,â said Mark VanGessel, a University of Delaware weed scientist.
VanGessel spoke Jan. 22 during the Pennsylvania Agronomic Education Conference.
