Disease resistance codes are a way of indicating the susceptibility of a plant to specific diseases. The codes are typically abbreviations that correspond to specific diseases, and they can help gardeners select plants that are resistant to those diseases.
Here are some common disease resistance codes for vegetables:
-
A: Alternaria (a fungal disease that affects a wide range of vegetables, including tomatoes, peppers, and eggplants)
-
F: Fusarium (a fungal disease that affects a wide range of vegetables, including tomatoes, peppers, and eggplants)
-
V: Verticillium (a fungal disease that affects a wide range of vegetables, including tomatoes, peppers, and eggplants)
-
N: Nematodes (small worms that can damage the roots of plants)
-
T: Tobacco mosaic virus (a viral disease that affects a wide range of vegetables, including tomatoes, peppers, and eggplants)
-
PM: Powdery mildew (a fungal disease that affects a wide range of vegetables, including pumpkins, squash, and cucumbers)
-
DM: Downy mildew (a fungal disease that affects a wide range of vegetables, including pumpkins, squash, and cucumbers)
-
CMV: Cucumber mosaic virus (a viral disease that affects a wide range of vegetables, including cucumbers, melons, and squash)
-
WMV: Watermelon mosaic virus (a viral disease that affects a wide range of vegetables, including watermelons, cucumbers, and squash)
-
TSV: Tomato spotted wilt virus (a viral disease that affects a wide range of vegetables, including tomatoes, peppers, and eggplants)
-
P: Potato virus Y (a viral disease that affects potatoes and other vegetables in the Solanaceae family)
-
BB: Black leg (a bacterial disease that affects a wide range of vegetables, including potatoes, tomatoes, and peppers)
-
BS: Black scurf (a fungal disease that affects potatoes)
-
RL: Root-lesion nematodes (small worms that can damage the roots of plants)
-
S: Southern blight (a fungal disease that affects a wide range of vegetables, including tomatoes, peppers, and eggplants).
It's important to note that disease resistance codes are not a guarantee that a plant will be completely immune to a specific disease. Instead, they indicate that a plant has a lower level of susceptibility to that disease compared to other varieties. It's always a good idea to practice good gardening techniques, such as rotating your crops, avoiding overcrowding, and watering properly, to help prevent the spread of diseases in your garden.
These codes can be found in our seed catalog on page 7.
