If you haven’t heard, it’s the only canola system that delivers control of flushing weeds.

The word is spreading - Clearfield® canola is giving growers the kind of results they can’t stop talking about. It’s easy to use and the benefits are exceptional. So say goodbye to your weeds and hello to your neighbour, because you’ll be dying to tell them all about Clearfield.

Clearfield controls weeds with a single in-crop weed control application, saving time you might ordinarily have to spend in the sprayer. And less weeds means less time worrying about losing yield potential.

Clearfield also works hard to take out volunteer InVigor Liberty Link® or Roundup Ready® canola.

Common Questions

What is the Clearfield Production System?

Clearfield is a crop production system combining specific herbicides and seeds from crop varieties that have been traditionally bred for herbicide tolerance and high yields.

The wide range of available Clearfield herbicides allows growers to customize weed control for pressures specific to their crops while maintaining sustainability in resistance management plans.

Are Clearfield canola varieties Genetically Modified Organisms (GMO)?

No. All registered or soon-to-be registered Clearfield canola varieties were developed using traditional plant breeding methods. Therefore, Clearfield crops are treated as non-GMO, conventional crops and are approved for export worldwide.

Which herbicides can I use on Clearfield canola?

One of the key benefits of the Clearfield Production System for canola is that it offers choice. Growers can select the herbicide that best matches their weed control needs, depending on specific weed pressure, timing, rotation plans and sustainability strategies.

The current herbicides registered for use in Clearfield canola are: Ares, Odyssey® Ultra*, Odyssey NXT, Odyssey Ultra NXT, Solo®, Solo ADV, and Solo Ultra.

How do I control volunteer Clearfield canola in my peas?

You can use Basagran herbicide to control volunteer Clearfield canola in your field peas. Basagran is also a Group 6 herbicide, making it an excellent resistance management tool.

What is the Clearfield Commitment?

The Clearfield Commitment is an agreement between a grower and BASF that serves as a license, allowing the grower to access the benefits of The Clearfield Production System technology. It has now changed from a yearly Commitment to an evergreen Commitment for all Clearfield crops. This means that growers who sign a Commitment in 2015 will not be required to sign again in the future. If growers did not sign a Commitment in 2015 or 2016, a signed Commitment will be required for the 2017 growing season. Similar to previous years, growers must sign and have the Commitments submitted by July 7, 2017. In the case of Clearfield canola, growers pay a Clearfield Commitment Fee of $70/bag when they purchase seed.

Overview of the Clearfield® Commitment for canola.

The Clearfield Commitment, an agreement between the grower and BASF, is an important part of growing Clearfield canola.
