Late blight, caused by Phytophthora infestans, is a common and devastating disease for potatoes. Unfortunately, Black Queen potatoes have low resistance to late blight on their tubers. This means that the tubers are susceptible to rot and damage if exposed to the pathogen, especially in wet conditions. To manage this risk, gardeners should focus on preventive measures such as crop rotation, careful irrigation practices, and, if necessary, the use of fungicides during times of high disease pressure.

2. Resistance to Late Blight on Foliage: Mixed (Low to Medium)
The resistance to late blight on foliage is also limited for Black Queen potatoes, with laboratory tests showing low resistance but field tests indicating a medium level of resistance. This mixed result suggests that, while the foliage can endure some exposure to late blight, it may still be susceptible under severe conditions. Gardeners should monitor the plants closely for signs of blight, especially during humid and rainy periods, and consider proactive measures to protect foliage, such as applying copper-based fungicides and promoting good air circulation.

3. Wart (Synchytrium endobioticum): Field Immune
One of the strong points of Black Queen potatoes is their field immunity to potato wart disease, a serious soil-borne disease caused by Synchytrium endobioticum. This immunity is highly advantageous, as wart can devastate potato crops and persist in soil for many years. With field immunity, Black Queen potatoes are a safer choice for planting in areas with a history of wart disease.

4. Resistance to Gangrene (Phoma foveata): High to Very High
Black Queen potatoes show strong resistance to gangrene, caused by Phoma foveata. This fungal disease affects tubers in storage, causing dark, sunken lesions. With high to very high resistance, Black Queen potatoes are well-suited for longer storage periods, making them a good option for growers and consumers who wish to keep their harvest fresh for extended use.

5. Resistance to Dry Rot (Fusarium spp.): Low
Dry rot, caused by Fusarium species, is a common storage disease that affects potatoes with weakened resistance, leading to shriveled, rotting tubers. Black Queen potatoes have low resistance to dry rot, making them vulnerable to this disease under poor storage conditions. To prevent dry rot, it’s important to cure Black Queen potatoes properly after harvest and store them in cool, dry, and well-ventilated conditions.

Black Queen Potato Resistance to Bacterial Diseases

While fungal diseases are a major concern for potatoes, bacterial diseases can also impact crop quality and yield. For Black Queen potatoes, the primary bacterial disease of interest is the common scab, which is caused by Streptomyces scabies. Here’s a look at the Black Queen variety’s resistance to this disease and tips for managing scabs in the garden.

Resistance Profile to Bacterial Disease

Resistance to Common Scab (Streptomyces scabies): Medium
Black Queen potatoes exhibit a medium level of resistance to common scab, which means they have a moderate capacity to withstand the disease but can still be affected under unfavorable conditions. Common scab causes rough, cork-like lesions on the surface of tubers, which can reduce their market quality and make them less visually appealing. While these scab lesions don’t affect the flavor or nutritional value of the potato, they may be undesirable for certain culinary uses and for presentation.

With medium resistance, Black Queen potatoes can generally produce healthy tubers in conditions that are less conducive to scab development, though additional care may be required to manage this disease in soils prone to it.

Black Queen Potato Resistance to Virus Diseases

Virus diseases can be a significant challenge for potato crops, as they are often spread by aphids and other insects and can lead to reduced yield and quality. For the Black Queen potato variety, resistance to several common potato viruses is mixed, meaning gardeners should take precautions to protect their crop from potential infections. Here’s a detailed look at Black Queen’s resistance to major potato viruses and tips on managing these risks.

Virus Disease Resistance Profile of Black Queen Potatoes

1. Resistance to Potato Virus A (PVA): Low
Black Queen potatoes have low resistance to Potato Virus A (PVA), which can cause symptoms such as leaf mottling, stunted growth, and reduced tuber production. PVA is typically spread by aphids, so it’s important to control aphid populations to prevent infection. Regular monitoring and using organic insecticides or beneficial insects like ladybugs can help reduce aphid numbers.

2. Resistance to Potato Virus B (PVB): Medium to High
For Potato Virus B (PVB), Black Queen potatoes show a medium to high level of resistance, making them more resilient to this particular virus. While PVB can affect plant growth, the higher resistance level of Black Queen potatoes reduces the likelihood of infection and the potential impact on crop health and yield.

3. Resistance to Potato Virus C (PVC): Low
Resistance to Potato Virus C (PVC) is low in Black Queen potatoes, meaning they are susceptible to this virus. PVC can cause a range of symptoms, including leaf curling, yellowing, and reduced tuber quality. Since PVC is also spread by aphids, managing aphid populations is essential to minimize the risk of infection.

4. Resistance to Potato Virus X (PVX): Low
Potato Virus X (PVX) is another virus to which Black Queen potatoes have low resistance. Although PVX often causes mild or no symptoms on its own, it can lead to severe damage when combined with other viruses, a phenomenon known as “synergistic interaction.” Maintaining good crop hygiene, using certified disease-free seed potatoes, and practicing crop rotation can help prevent the spread of PVX.

5. Resistance to Potato Virus Y (PVY): Low to Medium
Black Queen potatoes exhibit low to medium resistance to Potato Virus Y (PVY), a virus that can cause mosaic patterns on leaves, leaf drop, and yield reduction. PVY is spread primarily by aphids, so controlling aphid populations can help mitigate the risk. Choosing certified seed potatoes and regularly inspecting plants for symptoms can also reduce PVY impact.

6. Resistance to Potato Leaf Roll Virus (PLRV): Medium
The Black Queen potato shows medium resistance to the Potato Leaf Roll Virus (PLRV), which can cause leaf curling, plant stunting, and poor tuber development. PLRV is spread by aphids and often causes greater damage in later stages of plant growth. The medium resistance provides some protection, but additional care, like aphid management and monitoring, is essential.
