Puccinia psidii is a rust pathogen native to Brazil in 1884 by some Brazilian guy who noticed his plants looked pretty rusty and then they made it a fungal disease, it has a very broad host range in the myrtle family and is a species of Puccinia
Thanks to globalisation it has managed to spread to places like africa and hawaii(not the phone)
The disease is proberbly native to brazil but has spread throughout the world
*basically rose black spot buta different colour lmao*
there is currently no cure : (
Puccinia produces spores which are released under wet conditions and usually spread by rain-splash. The disease can also be passed from plant to plant on hands, clothing or tools. Spores overwinter mostly on the shoots, but can survive on fallen leaves and within the soil.
There is under a 10% minor leaf spots. foliage, stem and branch dieback to reduced fecundity. Tree death, in most cases rust will grow over parts such as leaves,stem and shoots (i have no idea what pranav or louie wrot ehere lmao)
To prevent Puccinia from spreading you should remove all infected parts and destroy them. For bramble fruits, remove and destroy all the infected plants and replant the area with resistant varieties.Clean away all debris in between plants to prevent rust from spreading and Avoid splashing water onto the leaves, as this can help spread rust.
There is no resistance , usally just cover a plant in some spray and it will be fine , you can try scraping off the rust or cutting off infected branch
It kills the plant becaus it stops sunlight reaching it and stuff and uses up surface resouces , its basically another skin for the black rose spot disease
Thanks for reading
