Nearly all farmers will tell you among the best parts of agriculture is the independence to operate their businesses as they see fit. But across the crop-diverse northern Plains, weeds often can be the decision-makers.

“The big issue when it comes to crop rotations is we don’t have a lot of choices,” explains James Baguley, territory manager for Corteva Agriscience in western Montana. “Ideally, we can plant a cereal crop and then rotate to what we would consider our cash crops — lentils, chickpeas, oil seeds, potatoes, etc.”

Until now, herbicide carryover and subsequent crop injury have limited that flexibility. New Tolvera^™ herbicide from Corteva Agriscience significantly broadens cropping options following spring or winter wheat, durum or barley. Tolvera herbicide allows producers to control or suppress their most troublesome broadleaf weed and grass species, including green and yellow foxtail (pigeongrass), kochia, lambsquarters, prickly lettuce, Russian thistle, pigweed, and many others, while preserving the flexibility to rotate to the crop they determine fits best for their individual situation.

“With Tolvera herbicide, a producer doesn’t have to lock in to a crop for next year,” Baguley says. “That’s important, given the constant market fluctuations. It opens the decision-making window. They don’t have to speculate so far out whether prices will be better for canola versus the pulse crops or versus another crop. This can alleviate a lot of anxiety for producers.”

SUCCESS WITHOUT SACRIFICE

Tolvera herbicide is a Group 6 and Group 27, 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor. Two modes of action — tolpyralate, an active ingredient new to the cereals market; and bromoxynil — help combat the spread of resistant weeds while providing flexibility in application and crop rotation. It offers a nine-month plant-back rotation to many important crops, including field peas, lentils, canola, chickpeas, soybeans and sunflower, in the northern Plains and Pacific Northwest regions.

“Previously in the cereals market, you could mix modes of action, but you always had to sacrifice one thing,” says Marcus Weatherhead, a Montana-based strategic account manager, Corteva Agriscience. “The nice part about Tolvera herbicide is when you look at crop safety, rotation flexibility and weeds controlled, you can mix up your modes of action without sacrifice. It’s a real easy button for growers.”

BROAD-SPECTRUM CONTROL

Dr. Joe Yenish, a Corteva Agriscience field scientist, has conducted extensive field trials with Tolvera herbicide. He sees an excellent fit across the northern Plains into the Pacific Northwest.

“Tolvera herbicide has been very consistent on kochia, Russian thistle, common lambsquarters, pigweeds and secondary species, such as narrowleaf hawksbeard,” Yenish says. “Bringing in a new active ingredient that adds green and yellow foxtail — locally known as pigeongrass — and barnyardgrass control without slippage on the broadleaf weeds is a huge benefit for the eastern half of Montana and the bulk of the Dakotas.” Moving into the Pacific Northwest, where kochia is less of a driver, Tolvera herbicide is just as strong on pigweed and lambsquarters.

An emulsifiable concentrate (EC) formulation, Tolvera herbicide is tank-mix-friendly and -compatible with many grass and broadleaf herbicides. Growers can apply Tolvera herbicide to spring and winter wheat, durum and barley starting at the one-leaf stage all the way up through jointing, giving growers a wide application window for maximum control of actively growing weeds less than 4 inches tall.

“Rotational flexibility with Tolvera herbicide lets producers select the crop they want to grow and still keep a rotation window that allows them to adjust with the fluctuation of commodity prices and input costs,” Weatherhead says. “They can pick the crop that best fits the economics of their individual operation.”
