tree chemo..

...to fight off Phytophthora Dieback, 'a devastating plant disease of native plants, horticultural crops and garden plants worldwide.'
The jarrah and karri trees in our morning walk forest are currently being treated for dieback with many trunks braceleted by these chemjet syringes introducing phosphite into the tree.
A biodegradable fungicide that protects against dieback by boosting the plant's natural defences, phosphite is injected it into the plant's water transport system.
Sadly, human activity has caused the most rapid spread of the pathogen. Our park has newly installed very basic boot and shoe brushes which I will use religiously having read about dieback for this blip.

Meaning 'plant destroyer' in Greek, in Western Australia the species that causes the most severe and widespread damage to native plants in WA is P. cinnamomi .
Acting 'like a Biological Bulldozer in bushland by killing many susceptible plant species. Over 40% (2,300) of the native plant species and half of the endangered plant species in the south-west of WA are susceptible. When Phytophthora dieback spreads to bushland, it kills many susceptible plants, resulting in a permanent decline in the diversity of the whole ecosystem. It can also change the composition of the bushland by increasing the number of grasses and reducing the number of shrubs. Native animals that rely on susceptible plants for survival are reduced in numbers or are eliminated from sites infested by Phytophthora dieback.'
