New herbicide premixes announced at Commodity Classic

Antares Complete, Perpetuo will be available for farmers in 2020.

There’s activity in the corn and soybean herbicide market at this year’s Commodity Classic in San Antonio, Texas. Here are some of the product announcements and other developments that have occurred so far.


Helena unveiled two new herbicide premixes. Antares Complete is a preemergence residual herbicide that aims at a number of grasses and broadleaves in soybeans including pigweeds, lambsquarters, common ragweed, cocklebur, and weeds that resist glyphosate and herbicides from other herbicide groups. It combines the active ingredients of:
* Metribuzin (Group 5)
* Sulfentrazone (Group 14) 
* S-metolachlor (Group 15) 

Antares Complete will be available during the 2020 cropping season. Mark Wayland, manager of Helena herbicide brands, says the ratio between the three active ingredients was balanced to help ensure optimal performance and crop safety.

Empyros is a preemergence and early postemergence corn herbicide that’s set to hit the market in 2021. Wayland says the herbicide mix contains tolpyralate, an HPPD inhibitor (Group 27) herbicide that’s new to the U.S. Also included in the mix is S-metolachlor (Group 15). This mix aims at a mix of grasses like barnyardgrass and the foxtail species and also broadleaf weeds.


American Vanguard Corporation (AMVAC) officials outlined four herbicides that the firm purchased from Corteva Agriscience last year. 

Classic is a Group 2 postemergence herbicides used in soybeans that can serve as a tankmix partner for a number of postemergence products to expand the weed-control spectrum, says Nathaniel Quinn, AMVAC marketing manager for corn and soybeans. 

Hornet is a premix of flumetsulam (Group 2) and clopyralid (Group 4) herbicides that controls broadleaves in corn, including glyphosate-resistant ones, says Quinn. 

FirstRate is a Group 2 preemergence and postemergence soybean herbicide that targets glyphosate-resistant weeds. 

Python is a Group 2 herbicide that is used in situations like burndown applications. 

AMVAC is also developing chemistry to bring to market including Sinnate herbicide. It’s a new glufosinate premix that also contains the active ingredient topramezone (Group 27) that’s in Impact herbicide.

Company officials expect EPA registration to occur in the first quarter of 2020. A commercial launch is expected this fall. Company officials say it aims at postemergence weed control of herbicide resistant and driver weeds in LibertyLink corn. 


EPA registration is still pending for the Group 27 herbicide (Alite 27) that matches BASF’s GT27 and LibertyLink GT27 stacks. Farmers did plant 8 million acres of GT27 and LibertyLink GT27 stacks in 2019. However, all other Group 27 herbicides are off-label and illegal to apply to these soybeans. 

BASF also has a new herbicide site of action for the corn and soybean market that’s slated for the early 2030s. It also has a new PPO inhibitor (Group 14) technology that will control some current PPO-resistant weeds. Slated for the early 2020s, one of these herbicides will initially be launched for preplant and burndown situations. The trait technology that allows it to be used postemergence is slated for the early 2030s. 

Operation Weed Eradication

Last September, BASF launched Operation Weed Eradication. “Its objective is to shift how we as an industry think about weed control,” says Darren Unland, BASF technical marketing manager. “It shifts from managing weeds to eliminating them in a given field.” 

The driver for this has been the explosion of Palmer amaranth and waterhemp. BASF officials have calculated these weeds have burned through $2.5 billion worth of chemistry so far. 

Besides chemical, Operation Weed Eradication also stresses mechanical and cultural ways to eliminate weeds. As part of Operation Weed Eradication, BASF announced a collaboration with AGCO at Commodity Classic. “In some cases that means developing new sensors, systems, or machines; but in others it means collaborating with industry partners like BASF, to solve problems together,” said Darren Goebel, AGCO director of global agronomy and farm solutions, in a BASF press release. 

Perpetuo Herbicide 

Valent has launched Perpetuo, which Valent has positioned as an overlapping residual postemergence herbicide to follow a foundation preemergence residual herbicide.  Perpetuo is a mix that includes pyroxasulfone, a Group 15 herbicide, and flumiclorac, a Group 14 herbicide. 

Enlist Weed Control System

The Enlist Weed Control System has its full-scale launch in soybeans this year. It confers herbicide tolerance to a new 2,4-D formulation – 2,4-D choline – and glyphosate in corn, soybeans, and cotton and fop herbicides in corn. Herbicide options include Enlist Duo, a mix of glyphosate, and 2,4-D choline. Enlist One is straight 2,4-D choline that can be tankmixed with approved label herbicides.

Corteva  announced last November that Liberty is the preferred tankmix partner for its standalone (just 2,4-D) Enlist One herbicide. 

Corteva has raised its market share estimates for the system’s E3 soybeans from 10% to 20% for this year, says Shawna Hubbard, Corteva product marketing manager.
