Many gardening friends have recently encountered this situation, where the leaves of the roses either have many brown spots or look like they have been scalded, even though nothing has been done to them. In severe cases, they even wither, which is really difficult.

What are the brown spots on the leaves of roses?

How to treat the rose rust disease?
In the early stages of rust disease, red spots will appear on the infected parts of the leaves. If left untreated at this stage, the rust disease will progress further and cause the leaves to develop necrotic scars that look like they have been smeared or scalded.
As the rust disease progresses, the leaves of the roses will gradually turn yellow and fall off, and in severe cases, it can cause the entire plant to wither.
Prevention and treatment methods for rust disease
The germination temperature of rust disease spores is between 1-25 degrees, so it is more common in late autumn. The pathogenic spores of rust disease enter through the stomata on the back of the rose leaves and require the presence of water droplets for invasion. Therefore, preventing rust disease requires more effort in environmental management.
