Herbicide hard on kochia, easy on the crop rotations

Apr 11, 2023

Growers in the dark brown and brown soil zone have a new herbicide option designed to control kochia in cereals.

Corteva Agriscience’s OnDeck has a Group 6 (bromoxynil) and a Group 27 (tolpyralate), an active ingredient that is new to the western Canadian cereal market.

Jason Smith, Corteva’s western portfolio marketing manager for cereal herbicides, said OnDeck will be a valuable tool to help fight herbicide resistant kochia.

Essentially, all kochia on the Prairies is considered resistant to acetolactate synthase inhibitor and there are populations resistant to glyphosate, dicamba, and fluroxypyr.

Last summer, kochia resistant to PPO inhibitors may also have surfaced in Saskatchewan.

Video: Our Own On-Farm Research Is the Best Source - Managing White Mold in Northeast Nebraska

If you assumed Nebraska was too hot and dry for white mold to be a problem in soybeans, think again.

This week we're featuring Galen Samuelson, a farmer and dealer from Wakefield, Nebraska, who knows all too well how devastating white mold can be.

"We don't have it consistently every year, but with our temperature and humidity, it can hurt us quite bad," Samuelson says. Looking for alternatives, he explains, "What I like about Heads Up is that it's non-harmful to the beneficial fungal colonies in the soil." Galen has been using Heads Up for several years now, after first hearing about it through a small ad in a regional newspaper. Watch below to hear about his journey.

When asked to write about Samuelson Seed, Galen said the following:

"Samuelson Seed is a 4th-generation, family-based company. It started with my grandfather, and I'm now starting to pass the torch to my son, Caleb."

"In the early 1990s, I started working with a company whose focus was on plant and soil health before those benefits were widely known. I've continued to keep plant and soil health the main focus in our farming operation decisions."
