It is well known and accepted that there are no new herbicide modes of action in the offing. However, soybean producers can look forward to new herbicide formulations and premixes that are being marketed to enhance weed management in the soybean crop. Producers can also expect added complexity when applying both old and new products to their crop [see article here with a link to article about EPA’s new herbicide strategy]. The following is a brief summary of what is “new” in this regard
Beyond Xtra. This Group 2 [ALS inhibitor] herbicide from BASF is labeled for postemergence [POST] control of certain broadleaf and grass weeds in soybeans [see label for weeds that are contolled]. Its active ingredient [AI] is imazamox.
Enversa. This herbicide, developed by Corteva Agriscience, is a residual with a proprietary formulation of encapsulated acetochlor [Group 15] that is labeled for preemergence [PRE] control of broadleaf and grass weeds that include Palmer amaranth, barnyard grass, and fall panicum. It is touted to be a preferred residual tankmix partner with Enlist One herbicide for Enlist E3 soybean varieties. Enversa has a wide application window that ranges from preplant to R2.

Liberty Ultra. BASF has developed this next-generation formulation of Liberty [glufosinate–Group 10] that contains L-glufosinate, which is a more active isomer of the glufosinate AI. It can be applied to soybean, corn, and cotton crops that are glufosinate-tolerant. Click here for BASF’s news release announcing the product and here for the recently-approved label. It is the first herbicide released under EPA’s herbicide strategy that was recently adopted.
Voraxor. This herbicide premix from BASF contains the AI’s trifludimoxazin [new herbicide AI] and saflufenacil [AI in Sharpen], both Group 14 herbicides that are PPO inhibitors. It is intended for use as a PRE herbicide that should be applied no more than 3 days after soybean planting.
