Hi everyone! I’ve noticed some yellow markings on a leaf of one of my miniature roses. So far, I’ve only found it on this one leaf. Does anyone know if this could be rose mosaic virus？
It’s possible but I’m no expert. If the plant is loosing vigor then it is more likely. The good news is it is not contagious between plants. There is a question of still using it in hybridizing as there is a very small possibility it transfers to the offspring.
Yes, that pattern strongly suggests infection with the Rose Mosaic Virus complex.
