About Dieback.

Phytophthora Dieback is a wide spread and serious plant disease caused by a group of microscopic soil-borne water moulds in the genus Phytophthora.

This video is an introduction on what you can do about it.

We can Treat Dieback on your land.


The Friends of Inglewood Triangle have been very appreciative of the work done by Bruno and his staff to treat the reserve for Phytophthora Dieback. They also delivered a great training workshop and worked with us to develop a set of Dieback management protocols for bush care. We have asked Bruno to come back and deliver that workshop to members who missed out last year

The overall course was very thorough. Great to learn from someone passionate about saving the environment.

From first contact Bruno was very professional about providing an engaging and relevant learning experience at a very reasonable price. He was easy to work with and very efficient. We began the incursion with an interactive classroom presentation that held the children’s focus through-out. The children (and teachers) loved it. We then went and did a field work activity. I highly recommend this incursion to support Biological Science and Sustainability Education programs.
