New Herbicides and Application Rules for 2025

Nov 27, 2024

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.

Video: Dicamba Returns for Georgia Farmers: What the New EPA Ruling Means for Cotton Growers

After being unavailable in 2024 due to registration issues, dicamba products are returning for Georgia farmers this growing season — but under strict new conditions.

In this report from Tifton, Extension Weed Specialist Stanley Culpepper explains the updated EPA ruling, including new application limits, mandatory training requirements, and the need for a restricted use pesticide license. Among the key changes: a cap of two ½-pound applications per year and the required use of an approved volatility reduction agent with every application.

For Georgia cotton producers, the ruling is significant. According to Taylor Sills with the Georgia Cotton Commission, the vast majority of cotton planted in the state carries the dicamba-tolerant trait — meaning farmers had been paying for technology they couldn’t use.

While environmental groups have expressed concerns over spray drift, Georgia growers have reduced off-target pesticide movement by more than 91% over the past decade. Still, this two-year registration period will come with increased scrutiny, making stewardship and compliance more important than ever.
