Abstract

Herbicide resistance develops if the weeds exist in the population and set fertile seed. Being vigilant, keeping weed populations low and stopping seed set is the best way to prevent glyphosate resistance development:

  • know the herbicide use history of each paddock. If glyphosate has been the dominant knockdown and spray-topping product used, it's time to change
  • conduct herbicide resistance testing to determine what herbicides are effective on key weeds
  • aim for maximum control
  • establish a more diverse rotation to increase the number of control tactics available
  • use non-herbicide control tactics at every opportunity
  • always monitor the success of each control tactic
  • rotate between herbicide moa groups
  • ensure survivors do not set seed to replenish the soil seed bank
  • avoid introduction or spread of weeds by contaminated seed, grain, hay, stock or machinery
  • manage weeds in surrounding non-crop areas (e.g. fencelines, tracks, silos and sheds)
  • review the control achieved, and adjust future management strategies accordingly.
