A recently published paper by Australian researchers (Effect of Austropuccinia psidii inoculum concentration on myrtle rust disease incidence and severity) has relevance for the wider myrtle rust community in this country. A key finding is that "disease incidence and severity were found to increase across all species as inoculum concentration increased, with notable increases for species considered to be tolerant or of lower susceptibility to myrtle rust".
