Losing all tomatoes to wilt with brown vascular streaking in western NC suggests bacterial wilt (Ralstonia solanacearum)—not Fusarium/Verticillium, since resistant varieties (Better Boy, Early Girl) were grown. The glass water test (white streaming from cut stem) confirms bacterial wilt.
| Disease | Key Sign | Management |
|---|---|---|
| Fusarium/Verticillium | Brown streaks in lower stem; resistant varieties available | Plant resistant cultivars (V, F, N labels) |
| Bacterial wilt | White milky stream in water test; no resistant varieties | Rotate to non-solanaceous crops for 3+ years |
| Southern blight | White mycelial fan at soil line; tan sclerotia | Daconil drench; corn rotation; solarization |
Phlox, hibiscus, blanket flower, and zinnia wilting with negative glass test indicates Rhizoctonia crown rot or similar soil fungi—not tomato pathogen spread. Drench with Daconil (2 tbsp/gal, ½–1 cup/plant) for suppression.
Sterilize pruners (10% bleach or alcohol) between plants—good practice, though bacterial wilt spreads mainly via water/soil, not tools.
