This service is available to improve efficiency of herbicide use, improve weed management decisions, and help to minimise herbicide wastage.
Charles Sturt University conducts screening of weed populations for resistance to commonly used herbicides. Identifying herbicide-resistant weeds enables producers to avoid using herbicides that are no longer effective against herbicide-resistant weeds, and provides valuable information to researchers about the incidence of herbicide resistance. This information is essential to efforts to limit the development and spread of herbicide resistance.
At present, the weed species that are routinely screened include annual ryegrass, wild oats, barley grass, brome grass, and wild radish. Seed of other weeds can be submitted for evaluation, but dormancy issues may prevent accurate determination of resistance
A summary of findings of testing for previous years can be on the Graham Centre Website
