Bad news on managing #PSHB (though not, sadly, entirely unexpected, given that no other place has managed to eradicate it): https://www.abc.net.au/news/2025-06-19/shot-hole-borer-eradication-not-possible-wa/105435866
I haven't seen an update on the combined herbicide/fungicide treatments that seemed to be showing promise, so I don't know if those fell through.
Some very welcome good news!
I've seen enough amazing results in smaller trials that proved difficult to scale up that I'm holding on to some caution, but this is so promising - not just for Boorloo/Perth but also for other places that are struggling to manage PSHB.
The Polyphagous Shothole Borer #PSHB has been impacting trees across the Perth metro area, with devastating consequences. What can you do to identify infected trees and help minimise the spread?
Join us for a community training session facilitated by staff from the Department of Primary Industries and Regional Development, to get the latest information about identification and containment of the PSHB threat.
An overview of the polyphagous shot hole borer in Western Australia from Aleisha Orr in @ausgeo. It not only has the potential to deplete urban tree canopy, but also to degrade native ecosystems and impact agriculture.
