These are two unrelated rust diseases. The one on the pear is due to cedar trees and wet springs.

The hollyhock rust Puccinia malvacearum,  infects hollyhock, causes yellow spots on the upper leaf surface, and orange-brown raised pustules on the lower leaf surface. Wet conditions promote infection by the rust fungus. The lower leaves typically show symptoms first, and the disease slowly progresses to upper leaves over the summer. Infected leaves eventually turn brown, wilt, and die. Wind and splashing rain help spread the spores of the fungus, so spacing plants to promote good air circulation can help slow the progression of the disease. Because wet conditions favor infection, water the soil around the plants rather than wetting the leaves with overhead irrigation if possible. There are hollyhock cultivars which are resistant to this disease.
