Post subject:  Research into Myrtle Rust Resistance on Australian Natives

Myrtle Rust is a fungus that was recently discovered which can have devastating effects on many popular plants. It is very distinctive, and produces masses of powdery bright yellow spores on infected plant parts consisting of spore-filled lesions on young growing leaves, shoots, flower buds and fruits.

Myrtle rust affects plants belonging to the Myrtaceae family including popular Australian natives such as Callistemons, Lilly Pillies, Tea Trees and Eucalyptus.

Understandably people have recently become weary of chosing popular Bottlebrush and the like, based on the risk that Myrtle rust poses. However, recent research into the effects of the fungus have shown that there are in fact many varieties of Australian natives available on the market that are resistant to Myrtle Rust.

This research conducted by Dr. Karanjeet Sandhu, a Myrtle Rust Pathologist from the University of Sydney, concluded that varieties of Bottlebrush and other native shrubs and trees in the Myrtaceae family can offer varying degrees of resistance to this toxic fungus.

Many plant varieties were tested and here are some of the results... read the full article here http://ozbreed.com.au/research-papers/r ... tives.html
