What is Beet Crown Gall Disease?
Beet Crown Gall Disease is a plant disease that affects beets and other members of the Chenopodiaceae family. It is caused by the bacterium Agrobacterium tumefaciens, which infects the roots and causes the formation of galls or tumors on the crown of the plant. These galls disrupt the normal functioning of the plant, leading to stunted growth, reduced yield, and overall decline in plant health.
| Definition | Symptoms | Control Methods |
| Beet Crown Gall Disease is a bacterial disease that affects the roots and crowns of sugar beets. | – Swollen and distorted roots and crowns.- Reduced plant growth and yield.- Wilting and yellowing of leaves.- Stunted and deformed plants. | – Use disease-free seed.- Rotate crops to prevent buildup of bacteria in the soil.- Practice good field sanitation.- Apply appropriate chemical treatments if necessary. |
What are the symptoms of Beet Crown Gall Disease?
The symptoms of Beet Crown Gall Disease include the formation of galls or tumors on the crown of the plant. These galls may vary in size and shape, but they are usually round and can range from small nodules to large swellings. The galls are often soft and spongy in texture and may be white, pink, or reddish in color. Infected plants may also exhibit stunted growth, yellowing of leaves, wilting, and overall decline in vigor.
- Swelling and distortion of the roots and stems
- Formation of rough, tumor-like galls on the crown and roots
- Reduced plant vigor and stunted growth
How does Beet Crown Gall Disease spread?
Beet Crown Gall Disease spreads through infected soil, contaminated tools, or infected plant material. The bacterium Agrobacterium tumefaciens can survive in the soil for several years, making it difficult to control. When healthy plants come into contact with infected soil or contaminated tools, the bacteria can enter through wounds or natural openings in the roots and establish an infection. Infected plant material can also introduce the disease to new areas if not properly managed.
- Infected beet plants release bacteria into the soil.
- The bacteria can survive in the soil for several years.
- Healthy beet plants can become infected when their roots come into contact with the bacteria in the soil.
- The bacteria enter the plant through wounds or natural openings in the roots.
- The bacteria then multiply and form galls, which are abnormal growths on the roots and crown of the plant.
What are the management strategies for Beet Crown Gall Disease?
Managing Beet Crown Gall Disease involves a combination of cultural, biological, and chemical control methods. Crop rotation is an important strategy to reduce the buildup of the bacteria in the soil. Avoid planting beets or other susceptible crops in infected areas for several years. Using certified disease-free seeds or transplants can also help prevent the introduction of the disease. Additionally, practicing good sanitation, such as cleaning tools and equipment, and removing and destroying infected plant material, can help reduce the spread of the disease.
| Prevention | Chemical Control | Cultural Control |
| Plant resistant varieties. | Application of bactericides. | Practice crop rotation. |
| Sanitation and cleanliness in the field. | Soil drenching with antibiotics. | Removal and destruction of infected plants. |
| Use of clean planting material. | Soil solarization. | Proper irrigation and drainage management. |
Are there resistant varieties available for Beet Crown Gall Disease?
Currently, there are no commercially available beet varieties that are completely resistant to Beet Crown Gall Disease. However, some varieties may exhibit partial resistance or tolerance to the disease. It is recommended to choose varieties that have been bred for resistance to other diseases and pests, as they may also have some level of tolerance to Beet Crown Gall Disease.
Yes, there are resistant varieties available for Beet Crown Gall Disease.

Can Beet Crown Gall Disease be controlled organically?
Controlling Beet Crown Gall Disease organically can be challenging, but there are several strategies that can help manage the disease. These include improving soil health through organic amendments, such as compost and cover cropping, to promote a balanced soil microbiome. Crop rotation with non-host plants and intercropping with pest-repellent crops can also help reduce disease pressure. Additionally, using biological control agents, such as beneficial bacteria or fungi, may provide some level of suppression against the pathogen.
Beet Crown Gall Disease can be controlled organically through cultural practices, crop rotation, and the use of resistant varieties.
What other crops are susceptible to Agrobacterium tumefaciens?
In addition to beets, Agrobacterium tumefaciens can infect a wide range of crop plants and ornamentals. Some of the susceptible crops include tomatoes, potatoes, peppers, cucumbers, melons, grapes, roses, and fruit trees. It is important to be aware of the potential for cross-infection when managing Beet Crown Gall Disease and to implement appropriate control measures for other susceptible plants in the vicinity.
Tomatoes
Tomatoes are also susceptible to Agrobacterium tumefaciens. Infection by this bacterium can lead to the development of crown gall disease in tomatoes.
Potatoes
Potatoes are another crop that is susceptible to Agrobacterium tumefaciens. This bacterium can cause the formation of galls on the roots of potato plants, leading to reduced growth and yield.
Cucumbers
Cucumbers are also known to be susceptible to Agrobacterium tumefaciens. Infection by this bacterium can result in the formation of galls on the roots and stems of cucumber plants, affecting their overall health and productivity.
