The current lack of suitable options for controlling aquatic plants in Australia creates great challenges to managers of aquatic ecosystems. In particular, the low number of herbicides registered for control of submersed and floating aquatic weeds greatly hampers management of aquatic invasive species.

Through data collection, this project will measure the efficacy of a new herbicide, and determine environmental limitations and factors that affect control success. You'll test native and introduced aquatic plants to identify suitable target plants and assess non-target damage. The information you gather will help register a new herbicide product in Australia that could be of great value to the management of aquatic weeds. It will also reduce the direct and indirect impacts of the herbicide on the aquatic ecosystem.

To improve the efficacy of a herbicide, it's crucial that the relationship between herbicide concentration and exposure time and resulting control of aquatic plants is established. This project will include experimental work in artificial pond systems to establish the minimum required exposure time needed for efficient control of target plants. You'll also investigate the effect of environmental factors, such as light availability or water turbidity, on herbicide efficacy.
