My project investigates herbicide resistance in annual ryegrass (Lolium rigidum) and the evolution of resistance to pre-emergence herbicides used for its control. This project is funded by the Grains Research and Development Corporation (GRDC). The main focus of this work is to provide strategies to prolong the effectiveness of these herbicides by incorporating diverse and sustainable crop production practices.


Group J herbicide dose-responses

Group J herbicide dose-responses: Resistant L. rigidum biotype (far back) vs two susceptible biotypes (front 2 rows). L. rigidum plants were sprayed with increasing amounts (L-->R) of triallate (top photo) or prosulfocarb (bottom photo).



This research is funded by a GRDC Research Scholarship and The University of Adelaide.
