Ozone symptoms on leaves of egg plants cv. Viserba are irregular, dark and small stipple (A, B, C, and E). In the beginning the injuries are hardly noticeable in the apex of the oldest leaves (E). In advanced stages, leaves are dried, chlorotic and senescent, however the ancient lesions still are easily recognizable (A and B).

The injuries are necrotic and irregular stipple (A and B). At the end of ozone exposure, leaves shows tan and stippling that gives an overall chlorotic appearance to the upper leaf surface (C).

Symptoms observed in the field
