Abstract
A review of previous studies indicate that many organically approved fungicides have moderate
field efficacy at best for the control of rust pathogens. This particularly poses a management
challenge for organic growers when faced with a rust incursion. Blueberry rust is caused by
Thekopsora minima, which was first detected in Australia in 2001 and has established widely
in Queensland and New South Wales. It was first detected in Tasmania in 2014 and whilst the
state was then declared rust free in mid-2016, several detections followed from late 2016 until
the present. Infected premises are managed under strict site management plans, as part of the
ongoing blueberry rust containment plan, which mandate hygiene protocols and include regular
fungicide sprays and monitoring. Organically certified blueberry growers currently have access
to only one registered fungicide, copper hydroxide. Trials are underway to compare efficacy of a
range of suitable products to expand options for organic blueberry producers. Glasshouse trials
using inoculated plants have demonstrated that a range of products (including biologicals and
inorganic compounds) can significantly reduce rust severity with efficacy close to that of copper
and mancozeb. Field trials in New South Wales using natural inoculation will be used to validate the
field efficacy of these results.
