Tomato spotted wilt

Symptoms - On vegetables symptoms can include stunting and yellowing, line patterns, mosaics, spots, concentric rings, necrotic streaks and distortions.

Tomato plants show bronzing, stunting and may be killed by severe necrosis. Leaves may be curled and have streaks and spots. Dark brown streaks may also appear on leaves, stems and growing tips. Ripe fruit may have paler red or yellow areas on the skin. Unripe fruit may develop necrotic rings.

On lettuce, infection usually starts on one side of the plant; the leaves become chlorotic with brown patches. The infection spreads to the heart leaves and stops growth on one side of the plant.

On ornamentals symptoms can include stunting, leaf mosaics and mottling, vein clearing, chlorotic spotting, leaf discoloration, ringspots, leaf and stem necrosis, flower breaking and general distortion of the plant.
