Helena Readies Production of Empyros Corn Herbicides

Corn weed control gets a fresh take this season as production starts on three Empyros corn herbicides from Helena Agri-Enterprises, LLC. Empyros, Empyros Triad, and Empyros Triad Flex recently received federal registration from the U.S. EPA. These groundbreaking pre- and early post-emergence herbicides provide excellent control of broadleaf weeds and grasses with novel combinations of the newest HPPD inhibitor to hit the U.S. corn market.

Empyros corn herbicides are built on tolpyralate, or what Mark Wayland, Manager of Herbicide Brands at Helena, calls a “backbone chemistry.” It’s combined with industry-standard herbicides, s-metolachlor and atrazine, to create exclusive two- and three-way pre-mixes. Together, these highly complementary active ingredients broaden the weed control spectrum and offer more versatility across geographies and planting conditions.

“When we talk to customers about what they want in a new herbicide, they often tell us flexibility, and that’s what we’re providing with the Empyros family,” says Wayland. “Each formulation is tailored for different needs across the country, and with long application windows, they can be applied on your schedule.”

Empyros is a pre-mix of tolpyralate and s-metolachlor, while Empyros Triad and Empyros Triad Flex add atrazine to the mix. Three years of research show Empyros herbicides rival and often exceed the performance of market-leading two-, three- and even four-way corn herbicide pre-mixes. With the introduction of tolpyralate, Empyros herbicides take a different approach to weed control with selectivity that provides strengths lacking in other corn herbicides.

“Tolpyralate is very strong from a post-emergence perspective, so along with activity on pigweeds, ragweeds and other common broadleaf weeds, we’re also able to get really good grass control that you don’t see with some of the other HPPD herbicides currently in the market,” says Dr. Michael Cox, Crop Protection Specialist for Research and Development at Helena. “When we couple that with a residual herbicide, we get a really complete product that gives a nice punch from one formulation.”

Empyros, Empyros Triad and Empyros Triad Flex will be available for the 2021 growing season, pending approval by state regulatory agencies. Customers are encouraged to contact their Helena representative or an authorized Empyros dealer to secure their orders now. Empyros herbicides are labeled for use in pre- and early post-emergence applications in corn.
