This project aimed to develop biocontrol agents for the control of ten weeds of importance in Australia. Five of these weeds are Weeds of National Significance (WoNS): cabomba, Sagittaria, prickly acacia, silverleaf nightshade and African boxthorn. New candidate biocontrol agents have been identified and underpinning research undertaken; applications have been made to the relevant authorities for their consideration for release into Australia. The project has also identified ways to integrate novel biocontrol solutions with other on-farm and off-farm weed management techniques.
