Nothing is more depressing than losing an entire crop of tomatoes. Tobacco mosaic virus, verticillium wilt and root-knot nematodes can damage and kill tomato plants. Crop rotation, garden hygiene measures and sterilizing tools can only control these problems to a limited extent. When these problems are present, the key to reducing tomato crop loss lies in selecting disease-resistant tomato plants.
Choosing Tomatoes Resistant to Disease
The production of disease-resistant tomato varieties is one of the main objectives of modern hybrid development programs. While this has been successful to some extent, no single tomato hybrid has yet been developed which is resistant to all diseases. Additionally, resistance does not mean total immunity.
Gardeners are urged to select disease-resistant tomatoes which are relevant for their gardens. If tobacco mosaic virus was an issue in past years, it only makes sense to select a variety resistant to this disease. To find disease-resistant tomato varieties, look on the plant label or seed packet for the following codes:
- AB – Alternarium Blight
- A or AS – Alternarium Stem Canker
- CRR – Corky Root Rot
- EB – Early Blight
- F – Fusarium Wilt; FF – Fusarium races 1 & 2; FFF – races 1, 2, & 3
- FOR – Fusarium Crown and Root Rot
- GLS – Gray Leaf Spot
- LB – Late Blight
- LM – Leaf Mold
- N – Nematodes
- PM – Powdery Mildew
- S – Stemphylium Gray Leaf Spot
- T or TMV – Tobacco Mosaic Virus
- ToMV – Tomato Mosaic Virus
- TSWV – Tomato Spotted Wilt Virus
- V – Verticillium Wilt Virus
