This is the time of the year when late-season pigweeds (waterhemp and Palmer amaranth) poke through the soybean canopy and produce seeds. These late-season pigweeds either emerged after herbicide applications, or survived inappropriately timed or less-than-effective postemergence herbicides. Given waterhemp and Palmer amaranth’s propensity to evolve resistance to herbicides, it is also possible that the survivors are resistant to the postemergence herbicide that was used.
