Christopher Preston

Professor Christopher Preston is a weed management specialist at the University of Adelaide's School of Agriculture, Food and Wine. His research focuses on herbicide resistance mechanisms in agricultural weeds, including biochemical pathways and population genetics. He leads the Weed Science Group studying resistance evolution in species like Sisymbrium orientale and Lolium rigidum.

Research interests include auxin herbicide resistance, gene amplification mechanisms (e.g., EPSPS in barley grass), and cross-resistance patterns in global weed populations. His work spans field surveys, molecular biology, and integrated pest management strategies.

Recent studies analyze glyphosate-resistant Conyza bonariensis populations and explore fitness costs of resistance mutations. Publications highlight genetic engineering applications for herbicide tolerance in crops.
