An exotic plant disease now in Mackay
Myrtle Rust Uredo rangelii is a serious fungal disease affecting the plant family Myrtaceae, which includes many Australian natives commonly found in our gardens, parks and natural environment. Paperbarks, Bottlebrushes, Lilly-pillies, Beach Cherry and Lemon-scented Myrtle are just some of the plants affected. The disease causes plant tissue to deform and die and is identified by its distinctive bright yellow spores and red pustules. The disease is easily spread on plants, via wildlife and on clothing and vehicles.
Recently introduced into Australia - Myrtle Rust is now widespread on our eastern seaboard from Victoria to the Wet Tropics. Myrtle Rust may slow regeneration of our native forests and could change forest biodiversity by reducing species and causing canopy leaf loss, affecting normal light and shade.
On May 8 2012, Biosecurity Queensland confirmed that Myrtle Rust had been found in Mackay on private property. On May 9, it was confirmed that Myrtle Rust had been detected at the Mackay Regional Botanic Gardens. The disease continues to spread and has now been recorded in several suburbs and natural environment areas around Mackay including Andergrove, Beaconsfield, Bucasia, Marian, North Mackay, Sarina, Slade Point, South Mackay and West Mackay.
The Mackay Regional Botanic Gardens is continuing to implement its Myrtle Rust Procedure to help protect our site from the spread of Myrtle Rust.
