Research Interests

The Weed Science lab has a range of interests in weed management issues. These include the evolution, biochemical mechanisms of herbicide resistant weeds, gene flow from herbicide tolerant crops and its implications for farm management, risk assessment for weeds and herbicide tolerant crops and patterns of genetic diversity in weed populations. Current projects include:

  • Understanding and management of glyphosate resistant weeds

  • New management practices for herbicide resistant grass weeds in no-till cropping systems

  • Integrated weed management of grass weeds in Southern Australian cropping systems

  • Gene flow in glyphosate tolerant canola

  • Mechanisms and inheritance of glyphosate resistance in Bromus diandrus

  • Mechansims and inheritance of resistance to 2,4-D, diflufenican, atrazine and ALS-inhibiting herbicides in Sisymbrium orientale

  • Mechanisms and inheritance of glyphosate resistance in Echinochloa colona

  • Biology and management of emerging weeds

  • Understanding behaviour of pre-emergent herbicides in disc seeding systems

  • Resistance to ACCase-inhibiting herbicides in Hordeum spp. and its management

  • Managment of resistance to clethodim in Lolium rigidum

  • Glyphosate resistance in Conyza bonariensis and its management

  • Novel herbicide tolerance in pulse crops
