Trials investigate potential quinoa herbicides

 University of Idaho trials are identifying good possibilities for herbicides that could be used in quinoa production.

Quinoa is raised in replicated trial plots at University of Idaho’s Aberdeen Research and Extension Center to find herbicides that control weeds in the crop.

 

 

 

ABERDEEN, Idaho — A weed scientist has found a few promising leads in her field trials to identify herbicides that can be used in quinoa production.

University of Idaho Extension weed specialist Pam Hutchinson explained U.S. growers currently have no herbicides labeled for weed control in the high-protein, gluten-free specialty grain.

Production of quinoa — which contains every amino acid and is regarded as a health food — is on the rise in Eastern Idaho, where it’s proven to be a good fit in potato rotations. The buyer who has contracted for all of the region’s quinoa acreage, Jeremiah Clark, has opened a quinoa processing facility in Idaho Falls and is already considering plans for expansion.

Hutchinson, who is in the second year of her quinoa replicated herbicide trials at UI’s Aberdeen Research and Extension Center, has expanded the number of herbicides she’s testing this season. Hutchinson said a challenge with finding an effective quinoa herbicide is that the crop is a close relative of the common weed lambsquarters. Products that control lambsquarters are also likely to kill quinoa.

Hutchinson has found several products that kill quinoa, to help growers clean their fields and prevent the crop from escaping and becoming a weed. She’s also evaluated herbicides that are known to effectively control lambsquarters and some that offer only moderate control.

Hutchinson said she’s found three products that are safe to quinoa and may control a host of weeds, while at least offering some degree of lambsquarters control.

Hutchinson said Syngenta’s Dual Magnum can be used both pre-emergence and post-emergence without harming quinoa.

Hutchinson has also had success with two older herbicides that were used in sugar beets before the release of genetically modified beets that resist glyphosate herbicide, rendering other products obsolete. Hutchinson said the beet products that tested well in quinoa, Ro-Neet and Norton, could be tough to find.

Clark, who supplied seed of his own proprietary quinoa varieties for Hutchinson’s trials, said his growers under contract planted 1,600 acres this season, and will likely plant more next season. He’s optimistic that Hutchinson’s efforts will lead to special-needs or permanent labels for quinoa herbicides. The absence of labeled herbicides has been a “big stumbling block” for growers, Clark said.

“A lot of farmers stay on top of their weeds, and if they go one year without controlling their weeds, they’ve got weed seed in the ground for several years,” Clark said.

Clark said many of his growers have kept weeds in check by increasing quinoa seeding density.

Hutchinson said a federally funded program that seeks to modify product labels to benefit minor crops, called Interregional Research Project No. 4, has also expressed interest in her trial results.

UI agronomist Xi Liang, is in the third year of trials in both Aberdeen and Tetonia investigating quinoa agronomic practices, including planting date and row spacing. Liang said her trials aren’t working well this season, due to challenging early season conditions, but she said it appears yields are higher in Tetonia, where the weather is cooler, and early season planting is preferable.
