Christophers' expertise include crop protection (weed management, herbicides, herbicide resistance); crop protection (resistance); weeds (management and control) and genetically modified crops.
The work Christopher does in The Weed Science lab includes a range of 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
Managing the risks of trifluralin resistance in no-till cropping systems
Integrated weed management of grass weeds in Southern Australian cropping systems
Dispersal and genetic variability of Sonchus oleraceus on a landscape scale
Ecology and management of trifluralin-resistant annual ryegrass in southern Australia
Gene flow in glyphosate tolerant canola
Mechanisms and inheritance of multiple glyphosate resistance in Lolium rigidum
Detection and management of weed patches
Mechansims and inheritance of 2,4-D resistance in Sisymbrium orientale
