In the later stage of the disease, the leaves of the whole plant were all covered with summer spores, resulting in the death of the aboveground part of the plant, the proliferation of phloem tissue at the junction of the stem base and the root or stem, the germination of latent buds, and the dwarfing of the plant. After the summer spores were re-infected, the leaves scattered on both sides.
