Implementation of specific management strategies for onion weed under stubble retention (chemical control trial) locations
Aims

To assess the chemical control options for effective control of onion weed without cultivation.

Key messages
  • Paraquat Treatments provided 100% control of all sizes of onion weed.
  • Ally treatments (metsulfuron) were slower than paraquat, however provided 100% control.
  • Double knocks improved the speed of burn off and control.
  • Glyphosate does not provide complete control of onion weed and recovery can occur.
  • Glyphosate mixed with Pyresta or Starane Advanced showed reduced glyphosate efficacy.
  • Glyphosate mixed with Valor and Sharpen showed no increase in control compared to glyphosate applied alone on all sizes of onion weed.
  • Local seeding machines successfully established canola into a heavy barley stubble and there was no benefit in pre-sowing cultivation or burning.
