Liberty Herbicide



A powerful extra tool for annual ryegrass control

Mode of action: Group 10 herbicide (formerly N)
Active ingredient(s): 200 g/L Glufosinate-ammonium
Formulation: Soluble concentrate (SL)

The Australian release of the LibertyLink® cropping system means Liberty Herbicide can now be sprayed over the top of those crops to enhance existing annual ryegrass management programs.

Liberty introduces an extra mode of action for our broadacre cropping and will help maximise the profitability of canola varieties that are tolerant to it.

Liberty can control a very wide range of weeds, including annual ryegrass populations with any level of resistance to glyphosate, clethodim and other herbicides that growers have previously relied on.

Key benefits

  • Added flexibility to deal with in-crop annual ryegrass pressure
  • Rapid control of many other grass and broadleaf weeds as well 
  • Reduced resistance issues and selection pressure on other modes of action

How it works

The active ingredient in Liberty is glufosinate-ammonium, a Group 10 herbicide which works by inhibiting the enzyme glutamine synthetase. Lack of glutamine synthetase leads to plant death through multiple disruptions of the plant metabolism, including the breakdown of photosynthesis.

Despite the absence of visual symptoms, the treated plants stop growing within the first day after application of Liberty. Complete death of the weeds usually occurs between two - four weeks after treatment.
