Determining the incidence of herbicide resistance in Australian grain cropping
There are currently 47 weed species which have confirmed herbicide resistance status in Australia. These are resistant to 10 different Modes of Action and 30 of these species are known to be weeds in crop production systems.
This investment seeks to further understand the incidence and extent of herbicide resistant weeds. Data from this project will inform investment decisions to develop strategies to manage and prevent resistance and support optimal weed management decisions.
