My role in the department

Alexandra leads a National research project, Locally Important Weeds, with co-funding from GRDC. This project focuses on four weeds of local importance to specific areas of the WA grainbelt. The weeds of concern are matricaria, marshmallow, feathertop Rhodes grass and stinking lovegrass. Biology and management of these weeds is being studied and the project aims to develop best practice guidelines for each weed. In addition to field research, Alexandra coordinates communication activities by members of DPIRD’s Crop Protection portfolio.
