Ink painting/drawing of peach leaf curl disease, caused by Taphrina deformans.

The painting shows a peach twig, which terminates in six leaves. The leaves are puckered and distorted. Two leaves are more heavily infected than the others, showing a characteristic downward and inward curl. The thickened, puckered leaf areas are orange-red, with some nearby zones showing chlorosis (turning yellow).
