LSU AgCenter researchers and extension specialists are working diligently to come up with alternative control programs to combat the problem of emerging resistance to glyphosate herbicide (Roundup) among weeds in cotton and soybean fields in Louisiana. Two weeds have been confirmed as resistant – Palmer amaranth (pigweed) and johnsongrass. Glyphosate resistance has proved costly to soybean and cotton farmers in other states. AgCenter scientists are hoping to minimize the losses in Louisiana.
