What is Bacterial Canker & Gummose Disease?
Bacterial canker and gummose disease are plant diseases caused by bacterial pathogens. Bacterial canker primarily affects fruit trees, such as cherry, plum, and peach trees, while gummose disease can affect a variety of plants including citrus trees, roses, and stone fruit trees.
| Definition | Symptoms | Treatment |
| Bacterial canker and gummose disease is a plant disease caused by bacteria. | – Dark sunken cankers on branches or trunks- Gumming or oozing of sap- Wilting or yellowing of leaves- Stunted growth- Dieback of branches | – Pruning and removing infected plant parts- Application of copper-based fungicides- Promoting plant health through proper watering and fertilization- Preventive measures such as planting disease-resistant varieties and maintaining good hygiene in the garden |
Bacterial canker is characterized by the formation of sunken cankers on the branches, trunks, or fruit of infected trees. These cankers may ooze a sticky substance and cause wilting or dieback of branches. Gummose disease, on the other hand, leads to the formation of gummy exudates on the affected plant parts, including branches, stems, or fruits.
What are the symptoms of Bacterial Canker & Gummose Disease?
The symptoms of bacterial canker and gummose disease vary depending on the plant species affected. In general, common symptoms include the presence of sunken cankers or gummy exudates on the infected plant parts. Other symptoms may include wilting, dieback of branches, leaf yellowing or browning, and fruit rot.
- Yellowing or wilting of leaves
- Formation of cankers on branches and stems
- Excessive production of gummy substances on affected areas
It is important to note that these symptoms can also be caused by other factors such as fungal infections or environmental stress. Therefore, proper diagnosis by a professional is crucial to accurately identify bacterial canker and gummose disease.
How are Bacterial Canker & Gummose Disease diagnosed?
Diagnosing bacterial canker and gummose disease requires a combination of visual inspection, laboratory tests, and analysis of symptoms. A trained professional will examine the affected plant parts for characteristic symptoms such as sunken cankers or gummy exudates.
- Visual examination of the affected plant: The first step in diagnosing bacterial canker and gummose disease is to visually inspect the affected plant. This involves looking for characteristic symptoms such as lesions, cankers, gummosis, or oozing of bacterial exudates.
- Laboratory analysis: To confirm the presence of the bacterial pathogens causing canker and gummose disease, a laboratory analysis is conducted. This may involve taking samples from the affected plant and culturing them on specific media to isolate and identify the bacteria.
- Molecular techniques: In addition to traditional culturing methods, molecular techniques such as polymerase chain reaction (PCR) can be used to detect and identify the bacteria causing canker and gummose disease. PCR amplifies specific DNA sequences, allowing for accurate identification of the pathogens.
- Diagnostic tests: Several diagnostic tests, such as serological tests or enzyme-linked immunosorbent assays (ELISAs), can be used to detect the presence of specific bacterial antigens or antibodies in the plant samples. These tests provide quick and reliable results.
- Symptom progression and host range: The progression of symptoms and the host range of the disease can also help in diagnosing bacterial canker and gummose disease. Observing how the symptoms develop and which other plant species are affected can provide valuable clues for accurate diagnosis.
In some cases, samples may be collected and sent to a laboratory for further analysis. These samples can be tested using techniques such as bacterial culturing or DNA analysis to confirm the presence of the bacterial pathogens causing the diseases.
What are the causes of Bacterial Canker & Gummose Disease?
Bacterial canker and gummose disease are caused by specific bacterial pathogens. The most common pathogens associated with bacterial canker include Pseudomonas syringae and Xanthomonas arboricola. Gummose disease, on the other hand, can be caused by various bacteria including Pseudomonas spp. and Xanthomonas spp.
| Poor Plant Hygiene | Infected Pruning Tools | Environmental Factors |
| Leaves and debris left on the ground provide a breeding ground for bacteria. | Using contaminated pruning tools can spread the bacteria from infected plants to healthy ones. | Excessive moisture and humidity create favorable conditions for bacterial growth. |
| Improper disposal of infected plant material can lead to the spread of the disease. | Not disinfecting pruning tools between cuts increases the risk of transmission. | High temperatures and prolonged periods of rain can promote the development of bacterial canker and gummose. |
| Failure to rotate crops and practicing monoculture can contribute to the disease’s spread. | Transplanting infected plants without proper precautions can introduce the bacteria to new areas. | Overwatering or poor drainage can create a moist environment ideal for bacterial growth. |
These bacteria can enter plants through wounds or natural openings, such as stomata or lenticels. They can also be transmitted through contaminated tools, pruning equipment, or infected plant material.
How can Bacterial Canker & Gummose Disease be managed?
Managing bacterial canker and gummose disease involves a combination of cultural, biological, and chemical control methods. Cultural practices such as proper sanitation, pruning infected plant parts, and removing diseased debris can help reduce the spread of the pathogens.
Effective management of Bacterial Canker & Gummose Disease includes pruning infected branches, applying copper-based fungicides, and maintaining proper sanitation practices.

In some cases, biological control agents or beneficial bacteria can be used to suppress the growth of the pathogenic bacteria. Additionally, applying copper-based fungicides or bactericides at appropriate times during the growing season may help control the diseases.
Are there any preventive measures for Bacterial Canker & Gummose Disease?
Preventing bacterial canker and gummose disease starts with selecting healthy plant material from reputable sources. It is important to inspect plants for any signs of disease before purchasing or planting them in your garden.
Preventive measures for Bacterial Canker & Gummose Disease include proper sanitation, pruning infected branches, and applying copper-based fungicides.
Other preventive measures include practicing good sanitation by regularly cleaning and disinfecting gardening tools, avoiding overhead irrigation that can promote disease spread, and providing proper nutrition and care to maintain plant health.
Can Bacterial Canker & Gummose Disease be cured?
Unfortunately, there is no cure for bacterial canker and gummose disease once a plant is infected. However, early detection and prompt management practices can help minimize the impact of the diseases and prevent further spread.
1. Prevention and Management
Bacterial canker and gummose disease can be managed through various preventive measures. These include:
– Proper sanitation practices, such as pruning and removing infected plant parts.
– Regularly inspecting plants for symptoms and promptly treating any infected areas.
– Providing optimal growing conditions, such as good drainage and appropriate watering.
– Avoiding over-fertilization, as excessive nitrogen can increase susceptibility to the disease.
– Using disease-resistant plant varieties whenever possible.
2. Chemical Control
In severe cases, chemical control methods may be necessary. This typically involves the use of copper-based fungicides or bactericides, which can help reduce the spread of the disease. However, it is important to carefully follow the instructions and dosage recommendations provided by manufacturers, as excessive or improper use of these chemicals can lead to negative effects on the environment and plant health.
3. No Absolute Cure
It is important to note that bacterial canker and gummose disease do not have an absolute cure. Once a plant is infected, it may be difficult to completely eradicate the bacteria. However, with proper management and control methods, it is possible to minimize the impact of the disease and prevent further spread. Regular monitoring, early detection, and timely intervention are key factors in successfully managing this disease.
It is important to remove and destroy severely infected plants to prevent the pathogens from spreading to healthy plants. Regular monitoring and implementing appropriate control measures can help reduce the risk of bacterial canker and gummose disease in your garden or orchard.
