Glufosinate-ammonium (Basta®, Liberty®) is the only Group 10 herbicide registered in Australia.
Resistance to Group 10 herbicides is rare and currently there are no documented cases of resistant weeds in Australia. Group 10 resistance has been discovered in other countries for 2 weed species – crowsfoot grass (Eleusine indica) and Italian ryegrass (Lolium perenne spp. multiforum) – which demonstrates the potential for weeds to develop resistance to this mode of action.
The risk of resistance to glufosinate-ammonium will be highest in situations where there is a reliance on this herbicide alone for weed control. This includes situations where:
Weed control from glufosinate-ammonium is affected by climatic conditions (refer to the product label).
In high summer rainfall areas, weed control in fallow is heavily reliant on herbicides. Multiple sprays are often required to maintain a clear fallow between winter crops.
The above recommendations should be incorporated into an Integrated Weed Management (IWM) program. In all cases try to endure surviving weeds from any treatment do not set and shed viable seed. Keep to integrated strategies mentioned in this brochure including cultural weed control techniques to reduce the weed seedbank. Make sure you mix and rotate herbicides from different mode of action groups. Always consult the product label prior to use.
