City of Canning trial combats beetle development and fungal growth in urban forests

An Australian-first scientific study using systemically-injected chemicals in the City of Canning local government area is showing early success, signalling a breakthrough in urban forest protection.

In collaboration with BioHerbicides Australia (BHA), ArbWest, the University of Queensland and Curtin University, the Council’s trial of 131 trees, which tests systemic chemicals to combat the Polyphagous Shot Hole Borer (PSHB), has produced promising results in managing the invasive pest.

The ground-breaking trial is showing significant progress in combating the Polyphagous Shot Hole Borer (PSHB). By testing innovative systemic chemicals, the trial of mature trees in the Canning River Regional Park, is proving to be a powerful solution in managing this invasive pest and safeguarding local ecosystems.

Explaining that the results demonstrate that the chemicals are effectively inhibiting beetle development and fungal growth, marking a significant advancement in the battle against the PSHB crisis, Canning Mayor, Patrick Hall advised "the initial trial results are incredibly encouraging and are a major milestone for the project team.

“This represents a game-changing approach to preserving our urban forests. It is absolutely vital that we build on this momentum, yet whilst other local governments stand ready to participate in further trials, those trials can only occur if additional government funding and support is provided.”

BHA researcher, John Szymanski added "while the initial results are promising, continued funding is essential to extend the trials and ensure long-term solutions

“The evidence shows we’re moving in the right direction, but to make a real impact, we need additional support.”

The Council has been working closely with the City of Perth, City of Vincent, Town of Victoria Park and the City of Gosnells, sharing information and collaborating to combat the PSHB infestation.

While these and other Local Government Authorities are eager to participate in the BHA trials and continue their efforts, the Council says securing Government support and funding is crucial to enable a coordinated, collaborative approach that can expand the trial and ensure long-term solutions for protecting urban forests.
