By observing the leaves of this plant, I find that there are many irregular reddish brown spots on the leaves, which vary in size. These spots may be caused by Grape black measles disease. The symptoms of Grape black measles disease on leaves include fading, circular, or irregular spots between leaf veins or along leaf edges. Under favorable conditions, these spots usually quickly spread outward to the distal end of the branches. Initially, small spots were scattered on the leaves, gradually expanding and merging, with some necrosis. Finally, the diseased leaves have dark yellow brown or reddish brown petioles. Sometimes the necrotic areas of the leaves become dry and separate, leaving irregular leaf edges.

Under favorable conditions, these spots usually quickly spread outward to the distal end of the branches. Initially, small spots were scattered on the leaves, gradually expanding and merging, with some necrosis. Finally, the diseased leaves have dark yellow brown or reddish brown petioles. Sometimes the necrotic areas of the leaves become dry and separate, leaving irregular leaf edges.
