Next Generation Herbicides

The EPA just cleared three new herbicide active ingredients for corn, soybeans, and wheat — and they’re aimed squarely at the weeds giving Southeast growers the most trouble: resistant Palmer amaranth, waterhemp, and marestail. In this episode we break down what each one actually is and where it fits: epyrifenacil (Valent’s Rapidicil, sold as Empera) and trifludimoxazin (BASF’s Tirexor and Voraxor) — two next-generation Group 14 PPO inhibitors built to control PPO-resistant pigweed that older chemistry can’t touch — plus diflufenican (Bayer’s Convintro), the first effective Group 12 “bleacher” residual for pigweed control in corn and soybeans. We keep it practical: how they differ from glyphosate, glufosinate, and the PPOs you’re already running; where they slot into burndown, preplant, and pre-emergence programs; why none of them is a silver bullet for Italian ryegrass in wheat; and how to use them to diversify sites of action instead of burning them out. If resistance management is on your mind heading into next season, this one’s for you.
