If rose rust occurs in flowers, first observe whether it is the whole disease or just a few leaves, if only the leaves get sick, then just remove the pathogen, that is, remove the leaves that get rust; if the whole plant gets sick, it is sprayed with 15% strychnine solution diluted a thousand times.
