North Dakota farmers reap multiple benefits from cereal herbicide choice
Cereal farmers embrace Tolvera® herbicide, which offers robust broadleaf and grass control and more crop rotation flexibility. With two modes of action — including tolpyralate, an active ingredient new to the cereals market — Tolvera herbicide helps improve herbicide resistance management and season-long weed control in cereal grains.
Fourth-generation farmer Brooks Heer farms with his brother, growing canola, soybeans, corn and spring wheat in central North Dakota, where kochia has historically been their most troublesome weed.
Then after touring fields sprayed with Tolvera® herbicide in 2024 and seeing how it performed, the brothers were impressed, so they added it to their herbicide program in 2025.
“We made one pass on our wheat when it was about the four- or five-leaf stage, and it cleaned up the kochia and also controlled pigeon grass, lambsquarters, green and yellow foxtail and Russian thistle,” Heer said.
If kochia is not controlled, it will deposit seeds into the seedbank, compounding weed control efforts next season. Heer rotates crops not only for the agronomic benefit but also for the weed resistance management benefit of rotating herbicides with different modes of action, like tolpyralate, a novel active ingredient in Tolvera herbicide new to the cereals market.
Heer likes the tank-mix flexibility of Tolvera herbicide, and the short plant-back periods to many other crops add value to his overall production and crop marketing efforts.
“Because we grow canola, we stay aware of chemical carryover that could limit our rotation options,” Heer said. “But Tolvera herbicide eliminates any concern there. It allows us to come back next year with canola, soybeans, corn or other crops that allows us to capitalize on commodity market fluctuations.”
“It’s reasonably priced, and that’s another reason we switched to it this year across almost all our acres,” Heer said.
Extending value with Tolvera® Plus Program
The value of Tolvera herbicide can be realized not only through the effective weed control it delivers but also from the benefits offered beyond the turnrow through the Tolvera® Plus Program.
“Tolvera herbicide is no doubt a game-changing product, but no herbicide is labeled to control every weed in the spectrum,” said Allen Pfennig, territory manager, Corteva Agriscience. “Because our team realizes farmers growing cereals need the added value of additional tank-mix options, we created the Tolvera Plus Program.”
The Tolvera Plus Program awards growers for purchasing other industry-leading herbicides within the Corteva Agriscience portfolio.
