Every year I get asked the same thing: Are there any new herbicides coming for the upcoming growing season?

Unfortunately, for the past several years, my reply has been that there are no new herbicide products with a new or unique mode of action, and that remains the same for 2024. But there are some new product premixes, revised formulations of existing active ingredients and trade names to consider for next growing season.

Here’s what’s coming:

Beyond Xtra 1SL. Beyond Xtra 1SL from BASF will be the new name for the imazamox-containing products. It will essentially combine the two labels of Beyond and Raptor, and it can be used in alfalfa, soybeans, snap beans, Clearfield sunflowers and a few other crops. Only Beyond Xtra is being produced now, but some Beyond and Raptor stocks may still be found in the marketplace until units are sold out.

Kyro 3.07CS. Kyro 3.07CS from Corteva is an encapsulated formulation that provides foliar and some residual control of annual grasses and broadleaves when applied post, up to 24-inch-tall field corn. The typical application rate is 45 fluid ounces per acre, but it 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 will be available for the 2024 growing season.

Liberty Ultra 1.76SL. Liberty Ultra 1.76SL from BASF is considered the next generation of Liberty herbicide. 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 formulation and will provide the same consistent performance and crop safety. It is expected to be available in 2024, pending EPA approval.

Maverick 2.04SC. Maverick 2.04SC from Valent has a wide application window from preemerge to 18-inch-tall corn, and it provides foliar and residual control of many annual grasses and broadleaves at 14 to 32 fluid ounces per acre. It can be tank-mixed with atrazine and other products. It is fully registered and will compete with products such as Resicore, SureStart II and Acuron.

Reviton 2.83SC. Reviton 2.83SC from Helm Crop Solutions can be used in a burndown program before field corn, soybeans or wheat. Corn or wheat can be planted immediately after application. Wait seven days to plant soybeans if using 2 to 3 fluid ounces, and at least four months to plant other crops. It has a low use rate (1 to 3 fluid ounces per acre) and can be tank-mixed with other herbicides, especially glyphosate. Methylated seed oil or crop oil concentrate, plus ammonium sulfate, must be added to the spray solution. Reviton is similar to Sharpen and is less active on marestail, but has better activity on field pansy/violet, primrose and some grasses.

Roundup PowerMax3. Roundup PowerMax3 from Bayer is a newer, high-load herbicide (4.8 pounds an acre equivalent) and glyphosate formulation. Since it is a higher-load product, the rate structure has been modified. PowerMax3 at 20 fluid ounces is equal to 22 fluid ounces of PowerMax (0.75 pounds an acre equivalent). The original PowerMax formulation is being phased out.

Storen 3.2ZC. Storen 3.2ZC from Syngenta is a new 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 preemerge application. The typical use rate is 2.1-2.4 quarts per acre, and it will provide residual control of many annual grasses and broadleaves, as well as foliar control of certain annual broadleaves.

Surtain 1.61ZC. Surtain 1.61ZC from BASF 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 and will be compatible with liquid fertilizer carriers. Surtain will provide residual control of annual grasses, and large- and small-seeded broadleaves. Possible registration by 2024, pending EPA approval.

Tendovo 4.14ZC. Tendovo 4.14ZC from Syngenta will primarily be used as a burndown with some residual in soybeans. It can be tank-mixed with other herbicides. Its use rates are 1.5-2.1 quarts per acre on medium soils and will provide residual control of many annual grasses and broadleaves. It is registered for use in our area.

TriVolt 4.09SC. TriVolt 4.09SC from Bayer can be applied from pre to V2 corn and provides residual control of many annual grasses and broadleaves. The typical use rate is 10-20 fluid ounces per acre. It is registered for use in field corn.

Voraxor 3.13SC. Voraxor 3.13SC from BASF is primarily a pre-burndown but has some residual activity on broadleaf weeds in soybeans. 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, with a possible sales launch by 2025.

Some wonder why there have not been any new and unique herbicide modes of action registered in the past decade or so. For that answer, wait until the next Talkin’ Weeds article for a discussion about that.
