| 5424478 | Tomato Spotted Wilt Virus | Tospovirus TSWV | Infected plant in the field showing symptoms on one side of leaves that might be confused with Fusarium wilt. |
| 5424475 | Tobacco Ringspot Virus | Nepovirus TRSV | Single TRSV-infected plant. |
| 5424476 | Tobacco Ringspot Virus | Nepovirus TRSV | Leaf on left with ringspots and small areas of "oak leaf" symptom. |
| 5424477 | Tobacco Streak Virus | Ilarvirus TSV | It is characterized by striking patterns of necrotic leaf tissue usually bearing a close relation to the veins. Some leaves may be affected on one side only. Midribs have dead streaks and the small veins are darkened. Stalks can show depressed dead areas. Apparently normal-growing plants develop necrosis, puckering, and curling of the young leaves. Affected plants appear permanently injured and likely to die; this severe stage soon passes, however, and the plants resume apparently normal growth, with only the originally affected leaves being misshapen and dwarfed. |
