What’s new in the herbicide world for 2025 and beyond? Don’t count on any new modes of action.

Most “new” products have additional active ingredients or are new premixes. Still, here’s a list of some of the new stuff you will find for next year, and some other stuff that is on the horizon:

Beyond Xtra 1SL, BASF. This will be the new name for imazamox-containing products. It will essentially combine the two labels of Beyond and Raptor, and can be used in alfalfa, soybeans, snap beans, Clearfield sunflowers and a few other crops. Only Beyond Xtra is being produced now, but Beyond and Raptor stocks can be marketed until they are depleted.

Enversa 3CS, Corteva. This is a new, proprietary encapsulated formulation of acetochlor (Group 15) for use in soybeans and corn.

This new formulation is designed to easily move from the foliage to the soil to provide residual control of many small-seeded annual broadleaves and grasses, and the capsule thickness varies to allow release of herbicide over an extended period. It also has excellent crop safety, easy handling and tank-mix compatibility.

The typical use rate is 3 pints an acre, and it can be applied in soybeans from pre- up to post-R2 stage, and post in corn up to 30 inches tall. It can be tank-mixed to broaden the weed control spectrum. It is currently registered and being marketed.

Intrava DX (amicarbazone + metribuzin; Group 5), UPL. This is a new experimental premix for use as a burndown or pre residual in field corn. It has activity on many annual broadleaf and grass weeds, including Palmer and waterhemp. It is currently not registered.

Kyro 3.07CS (acetochlor, or Warrant + topramezone, or Impact + clopyralid, or Stinger; Groups 15, 27, 4), Corteva. This an encapsulated formulation, and it provides foliar and some residual control of annual grasses and broadleaves when applied post up to 24 inches tall in field corn. The typical application rate is 45 fluid ounces an acre, but can range from 35 to 60 fluid ounces. It will likely be tank-mixed with glyphosate or atrazine to broaden the control spectrum. This product is registered and currently being marketed.

Liberty Ultra 1.76SL (glufosinate, Liberty; Group 10), BASF. This is considered the next generation of Liberty.

It contains L-glufosinate, which is a more active isomer and thus allows for lower use rates. For example, 24 fluid ounces of Liberty Ultra will be equal to 32 fluid ounces of current Liberty 280 formulation. This improved formulation causes greater spray droplet retention on the weed foliage and provides consistent performance and crop safety. It can be applied to glufosinate-resistant crops.

The application timing in soybeans is from emergence up to early bloom (R1 stage) and from emergence through R6 in corn. It is best to include AMS, spray at 15 to 20 gallons an acre and use nozzles that produce medium to coarse spray droplets.

It recently received EPA approval and will be marketed in .2025. Liberty 280 2.34SL may still be found in the marketplace until it is sold out.

NovaGraz (florpyrauxifen, or Rinskor active + 2,4-D; Group 4), Corteva. It was recently labeled for use in grass pastures and hayfields, as well as Conservation Reserve Program acres. It is safe on many types of forage grasses and preserves white clover. However, it will severely injure or kill other legumes such as red and crimson clover, alfalfa, and bird’s-foot trefoil.

It will control or suppress many broadleaf weeds such as ironweed, cocklebur, wild carrot, buttercup, biennial thistles, ragweeds, plantain, poison hemlock, dandelion, marestail and others. Unfortunately, it is weak on horsenettle, milkweed, hemp dogbane, Canada thistle and smooth bedstraw.

The typical rate is 24 fluid ounces an acre, plus methylated seed oil (MSO). It has minimal grazing restrictions (three days) after application for any class of livestock, including lactating animals. You must wait 14 days after application to harvest for hay, and wait 30 days to move manure to sensitive areas unless it is being applied to areas used for pasture, corn or wheat. These restrictions are unlike Milestone or GrazonNext products.

NovaGraz received federal registration and should be available in our region pending state approvals. This product was previously referred to as ProClova.

Rapidicil 0.46EC (epyrifenacil, Group 14), Valent. This is a PPO inhibitor herbicide, like Sharpen, and has activity on many annual broadleaves and certain grasses. However, it is weak on marestail.

Currently, it is being tested as a burndown product but might possibly be used to control weeds post in PPO inhibitor-tolerant crops currently being developed. It is still pending regulatory approval and might be launched by mid-decade.

Rely 2.34SL (glufosinate, Group 10). It will be discontinued by BASF and will no longer maintain its label for specialty crops (certain tree, vine, berry, cucurbit crops). Existing inventory of Rely can be used until it is exhausted. It is unknown if another company might add these crops to their glufosinate product label.

Resicore REV 3.26CS, Corteva. This is a reformulation of Resicore (acetochlor, mesotrione and clopyralid) and the old formulation will be phased out.

Resicore REV can be used in field corn, pre or post. The major change is the switch to encapsulated acetochlor for better crop safety and improved handling. This allows for a wider application window, up to 24-inch-tall corn (the original Resicore was up to 11-inch-tall corn).

The typical rate is 2.5 quarts an acre on medium soils. It can be tank-mixed to broaden the weed control spectrum and can be applied in a liquid fertilizer carrier. This product is currently being marketed.

Storen 3.2ZC (S-metolachlor, or Dual II Mag. + pyroxasulfone, or Zidua + mesotrione, or Callisto + bicyclopyrone; Groups 15, 27), Syngenta. This is a newer premix of four active ingredients, but it does not contain atrazine. It can be tank-mixed with atrazine or other products to broaden the weed control spectrum.

It can be applied from pre to post (V8 growth stage) in field corn and can be used in sweet corn, but only as a pre. The typical use rate is 2.1 to 2.4 quarts an acre and will provide residual control of many annual grasses and broadleaves, as well as foliar control of certain annual broadleaves.

Surtain 1.62ZC (saflufenacil or Sharpen + pyroxasulfone or Zidua); Groups 14, 15), BASF. This is a premix in a novel solid encapsulation formulation referred to as ZC. This new formulation allows pre or early post (V3) applications in field corn, not sweet corn, and is compatible with liquid fertilizer carriers.

Surtain will provide residual control of annual grasses, and large- and small-seeded broadleaves. A typical use rate is 14 fluid ounces an acre and can be tank-mixed. Also, if applying after corn emergence, include only NIS and AMS since COC/MSO and UAN can cause crop injury. Surtain is currently registered and being marketed.

Voraxor 3.13SC (saflufenacil, or Sharpen + a new PPO; Group 14), BASF. This is primarily a pre or burndown herbicide but has some residual activity on broadleaf weeds. This combination provides improved control of purple deadnettle, henbit, common chickweed and mouse ear chickweed compared to Sharpen. It will be labeled for use in soybeans, corn and wheat but does not yet have a federal registration.

Zalo 2.57SL (glufosinate + quizalofop; Groups 10,1), AMVAC. This is a specially formulated premix that is designed to provide post control of many annual broadleaf weeds and improve weedy grass activity in glufosinate-resistant soybeans.

Apply from 32 to 43 fluid ounces an acre and include AMS, plus a crop oil (COC or MSO) to improve activity. To avoid antagonism, apply one day before or seven days after when using 2,4-D-containing herbicides and avoid tank-mixing with dicamba. Zalo is now registered.
