Researchers say 23 weed species are now at high risk of developing glyphosate resistance, including several important grasses and damaging environmental weeds like fireweed and parthenium weed... Two hundred weed species were analysed to determine their innate likelihood to evolve and change in response to continued selection by herbicides in projects funded under the recently completed Department of Agriculture, Fisheries and Forestry (DAFF) National Weeds and Productivity Research Program managed by Rural Industries Research & Development Corporation (RIRDC), involving Department of Agriculture, Fisheries & Forestry Queensland and a number of other organisations... Project member, David Thornby, Queensland Department of Agriculture, Fisheries and Forestry (DAFF) says weed managers have a range of weed management tactics available to them for each species...

'Insurance' choices must be made between choosing to pay extra now to reduce resistance risk, and choosing to pay less now but more later when or if resistance occurs... We calculated total weed management costs per season for each scenario based on the number of applications of each control tactic assumed in Table 1... The grasses tested in these scenarios show a range of overall risk levels (Table 3), though all have high to very high levels of risk for glyphosate resistance...
