Red Jug, Different Rate — Key Considerations for Liberty AMP | Canola School

Why It Matters

Liberty AMP offers canola growers a more efficient, lower‑rate herbicide option that helps manage resistant weeds while reducing chemical use and application costs.

Key Takeaways

• Liberty AMP is 20% more concentrated, identified by red jug.
• Use lower application rate for Liberty AMP than Liberty 150.
• Maintain high water volumes and slower spray speed for efficacy.
• Rotate modes of action; Liberty Link offers new option for canola.
• Check labels, PPE, and weather; ensure proper coverage and safety.

Summary

The video introduces Liberty AMP, a new 20 percent more concentrated version of BASF’s Liberty herbicide for canola, distinguished by its red jug. Growers are warned that the formulation carries a lower use rate than the traditional Liberty 150 (blue jug) and that the color change is intentional to avoid confusion. Key insights include maintaining high water volumes, slowing sprayer travel to about 2 m / hour, and using a robust pre‑emergence burn‑down to reduce in‑crop stress. The product retains the same tank‑mix partners and application recommendations as Liberty 150, but its built‑in adjuvants (30‑50 % of the jug) reduce the need for additional surfactants. Rotating modes of action, especially with Liberty Link, is emphasized to combat resistant weeds like kochia. Sean McNite highlights practical tips: “Don’t be surprised if one of them is red,” and notes that the red jug signals the lower‑rate, higher‑concentration formula. He also stresses that proper PPE, weather checks, and maximizing coverage are essential for optimal performance. For growers, the launch means adjusting label rates, confirming jug color, and applying best‑management practices to preserve herbicide efficacy and delay resistance. The higher concentration can lower overall chemical usage and potentially reduce the need for a second in‑season application, delivering cost and labor savings.

Original Description

A new formulation of Liberty herbicide is hitting farms this season, and growers will want to pay close attention before heading to the field.

In this episode of RealAgriculture’s Canola School, Sean McKnight, technical marketing specialist for herbicides with BASF, says the launch of Liberty AMP brings a 20 per cent more concentrated formulation compared to Liberty 150, along with a few important management considerations for growers.

While the agronomic fundamentals of Liberty applications remain unchanged, McKnight says growers need to be especially mindful of product rates if both formulations are on the farm this year.

“Don’t be surprised if one of them is red… Liberty AMP is going to be different than 150,” says McKnight, noting the new formulation was intentionally coloured differently to help distinguish the products. “One is going to have a lower use rate than the other one. And so we don’t want anybody to be over applying herbicides, or under applying potentially on their fields as well.”

McKnight says the key to maximizing Liberty performance still comes down to strong application practices, especially as resistant weeds such as kochia continue to spread across Western Canada. He recommends using an effective pre-seed burnoff to reduce weed pressure ahead of the in-crop pass and rotating herbicide modes of action wherever possible.

When it comes to spraying Liberty products, water volume and coverage remain critical. McKnight says growers should prioritize warm, sunny spray conditions, increase water volumes in dry years, and even consider slowing sprayer speeds to improve efficacy.

“Even slowing down on your sprayer like two miles an hour… might save you from having to do a second application,” he says.

Tank mix partners, droplet sizes, and application recommendations remain largely unchanged between Liberty Amp and Liberty 150, and McKnight notes the product already contains built-in adjuvants, meaning additional surfactants typically are not required.
