AMVAC Corn and Soybean Marketing Manager Nathaniel Quinn says there are options for farmers managing resistant waterhemp and giant ragweed. “There are several new corn herbicides we’ve launched this year, including Impact CORE, that can help. Impact is a post-emergence corn herbicide with a wide application window. We’ve found there are instances when farmers want to combine a residual herbicide with the post herbicide to get the one-two punch for weeds.” Quinn says SINATE is another post-emergence corn herbicide for farmers to consider in 2021. “We’ve found that glufosinate used in conjunction with Liberty Link corn can provide a second mode of action on these weeds.”
