What tank-mix partners can I use with Liberty® herbicide to optimize its efficacy.

Before deciding on a tank-mix partner, scout your fields to know what your weed population looks like. By tank mixing Liberty herbicide with Centurion® herbicide, you enhance your grassy weed control. By adding Facet® L herbicide to the mix, you provide your fields with enhanced cleavers control.

How does Facet® L herbicide compare with Command® herbicide?

Facet L herbicide offers industry-leading, consistent control of cleavers with both systemic and contact activity (when tank mixed with Liberty® herbicide) for improved efficacy. It also provides flexibility to apply in-crop to effectively respond to pressure from cleavers.

How can I sign an LTA?

  • Through your authorized retailer, your local BASF Rep or call the AgSolutions® Customer Care at 1-877-371-BASF (2273)
  • Allow 5 business days for the LTA to be received and processed. An email will then be sent to the grower with his or her customer number and a copy of the signed LTA

What are the optimal conditions I should be looking for when applying Liberty® herbicide?

For optimal performance, Liberty herbicide should be applied in warm (10°C or higher) and sunny conditions. Wind, excessive moisture and cool, cloudy weather should be avoided when possible.


How do I control volunteer LibertyLink® canola?

  1. Do not use a Group 10 herbicide the following year after producing the commercial crop
  2. Preferably choose a crop that is not LibertyLink tolerant 

Can I apply Liberty herbicide more than once a season?

Yes, Liberty herbicide can be applied up to three times (up to 4.86 L/ac) in a single season. If considering a two-pass system, take the second pass in the reverse direction to target any foliage that could have been sheltered during the first pass.

The Liberty herbicide product label says to use high water volumes, why is that?

Liberty herbicide is a contact herbicide—meaning it only affects areas it comes in contact with. Maintaining higher water volumes (minimum 10gal/ac) will help to ensure good contact, improve coverage and increase the efficacy of the product.

How should I setup my sprayer when applying Liberty® herbicide?

Aim for coarse droplets (between 250 and 350 microns), while keeping pressures between 40 and 80 psi to increase coverage and reduce potential drift.

What is the Liberty and Trait Agreement (LTA?)

  • An evergreen agreement between BASF and the grower which grants a license to the grower to purchase LibertyLink® seed and Liberty® herbicide for use in growing a single commercial crop in Canada
  • Pertains to all LibertyLink canola (including InVigor® hybrid canola) and Liberty herbicide
  • Applicable to all patented traits contained in LibertyLink seed, not just LibertyLink traits
