NEW OPTION AVAILABLE SOON Sikkema previewed the arrival of diflufenican, a Group 12 herbicide and a new mode of action in corn. It’s the active ingredient in Convintro Corn and Convintro Corn 12 (diflufenican/isoxaflutole + S-metolachlor) and is expected to be available in Canada in 2026. The good news is it will provide control of a limited spectrum of weeds, including complementary activity on Amaranthus (waterhemp, redroot, green pigweed, and Palmer amaranth) species. However, he emphasized it is not a stand-alone herbicide, but it should control emerged weeds up to five centimetres in height. Table 1.
