Bacterial Canker & Gummose Disease: Causes, Symptoms, and Treatment
Bacterial canker and gummose disease are two common plant diseases caused by bacteria. These diseases can affect various types of plants, causing the development of cankers and gummy lesions on the affected plant parts. Understanding the symptoms and implementing proper management strategies is crucial to prevent the spread of these diseases and protect plant health.
Bacterial canker & gummose disease is a common bacterial plant infection that affects various fruit trees, including citrus and stone fruits. This destructive disease is caused by the bacteria Pseudomonas syringae, which enters the tree through wounds or natural openings. Symptoms of bacterial canker & gummose disease include oozing gum from infected areas, sunken lesions on branches and trunks, and dieback of twigs. To prevent the spread of this disease, it is important to practice good sanitation measures, such as removing and destroying infected plant material. Additionally, applying copper-based sprays during the dormant season can help control bacterial canker & gummose disease. Regularly monitoring trees for signs of infection and promptly treating affected areas can help minimize the impact of this destructive disease on fruit tree orchards.

What is Bacterial Canker & Gummose Disease?
Bacterial canker & gummose disease is a plant disease caused by bacteria that affects various fruit trees, such as cherry, plum, peach, and citrus trees. It is characterized by the formation of cankers or lesions on the branches, trunk, and fruit of the infected trees. These cankers may ooze gum or sap, giving the disease its name.

Bacterial infection that affects fruit trees, mainly citrus trees. | Fungal infection that affects various fruit trees, such as peach, cherry, and plum trees. |
Caused by the bacteria Pseudomonas syringae. | Caused by the fungus Botryosphaeria spp. |
Leads to the formation of cankers on branches, twigs, and fruit. | Leads to the formation of gummy exudates on branches, trunk, and fruit. |
What are the symptoms of Bacterial Canker & Gummose Disease?
The symptoms of bacterial canker & gummose disease vary depending on the affected tree species but commonly include sunken or raised cankers on the branches or trunk, wilting or dieback of shoots, gumming or oozing of sap from the cankers, and browning or discoloration of leaves and fruit. In severe cases, the infected trees may experience stunted growth and eventually die.
- Yellowing and wilting of leaves
- Formation of dark, sunken cankers on stems, branches, and trunk
- Exudation of gummy substance from cankers
How does Bacterial Canker & Gummose Disease spread?
Bacterial canker & gummose disease spreads through various means, including rainwater splashes, insects, contaminated pruning tools, and infected plant material. The bacteria enter the tree through wounds or natural openings and establish themselves in the vascular system, causing damage to the plant tissues.
- Through infected plant material: Bacterial canker and gummose disease can spread through infected plant material, such as infected branches, leaves, or fruit.
- Through contaminated tools: The disease can be spread through the use of contaminated tools, such as pruning shears or saws, which can carry the bacteria from one plant to another.
- Through insects: Certain insects, such as aphids or beetles, can act as vectors for the bacteria and spread the disease from infected plants to healthy ones.
- Through rain or irrigation water: Bacterial canker and gummose disease can be spread through rain or irrigation water, which can carry the bacteria from infected plants to healthy ones.
- Through human activities: Human activities, such as improper pruning techniques or the use of contaminated equipment, can also contribute to the spread of the disease.
Can Bacterial Canker & Gummose Disease be controlled?
Controlling bacterial canker & gummose disease involves a combination of cultural practices and chemical treatments. It is important to maintain good tree health through proper pruning, irrigation, and fertilization practices. Infected branches should be pruned and destroyed to prevent further spread. Copper-based fungicides or bactericides may also be applied to protect healthy trees or manage existing infections.
Preventive Measures | Chemical Control | Cultural Control |
Prune infected branches and dispose of them properly. | Apply copper-based fungicides to affected areas. | Plant disease-resistant varieties. |
Maintain proper tree nutrition and irrigation. | Use antibiotics to suppress bacterial growth. | Keep trees well-pruned to improve air circulation. |
Practice good sanitation in the orchard. | Apply biological control agents. | Remove and destroy infected plant debris. |
How to prevent Bacterial Canker & Gummose Disease?
Preventing bacterial canker & gummose disease involves implementing several preventive measures. These include planting disease-resistant tree varieties, providing adequate spacing between trees for good air circulation, avoiding over-irrigation or waterlogged conditions, and practicing proper sanitation by cleaning pruning tools between each use.
To prevent Bacterial Canker & Gummose Disease, practice good sanitation, remove infected plants, and use disease-resistant varieties.
Are there any natural remedies for Bacterial Canker & Gummose Disease?
While there are no specific natural remedies for bacterial canker & gummose disease, maintaining overall tree health through organic practices can help improve the tree’s ability to resist infections. This includes promoting a balanced soil ecosystem, using organic fertilizers, and applying beneficial microorganisms to the soil.
There are several natural remedies such as copper sprays, baking soda solutions, and neem oil that can help in managing Bacterial Canker & Gummose Disease.
Can Bacterial Canker & Gummose Disease affect other plants?
Bacterial canker & gummose disease primarily affects fruit trees but can also infect other plant species, including ornamental trees and shrubs. It is important to identify and manage infections promptly to prevent the spread of the disease to neighboring plants.
1. Bacterial Canker & Gummose Disease
Bacterial canker and gummose disease is a plant infection caused by certain bacteria, such as Pseudomonas syringae and Xanthomonas campestris. These bacteria primarily affect fruit trees, such as cherry, plum, apricot, and citrus trees.
The disease manifests in the form of cankers, which are localized areas of dead tissue on the branches, trunk, or fruit. These cankers can ooze gum, giving the disease its name. Infected plants may also exhibit symptoms such as wilting, leaf spots, and fruit rot.
Bacterial canker and gummose disease can be spread through contaminated pruning tools, insects, or wind-driven rain. It is important to properly sanitize tools and practice good plant hygiene to prevent the spread of the disease.
2. Impact on Other Plants
While bacterial canker and gummose disease primarily affect fruit trees, they can also infect certain other plants. Some ornamental trees, such as cherry laurel and flowering almond, are susceptible to these bacterial infections.
Additionally, certain crops like tomatoes and peppers can be affected by bacterial canker. These plants can serve as hosts for the bacteria, allowing them to survive and potentially spread to other susceptible plants in the vicinity.
It is important to identify and treat infected plants promptly to prevent the disease from spreading to other susceptible plants in the area.
3. Management and Prevention
Managing bacterial canker and gummose disease involves a combination of cultural, chemical, and biological control methods. Pruning infected branches and applying copper-based sprays can help control the spread of the bacteria.
It is also important to avoid overhead irrigation, as moisture promotes bacterial growth. Instead, water plants at the base to keep foliage dry.
To prevent the disease, select resistant varieties when planting fruit trees and maintain proper spacing between plants to improve air circulation. Regularly inspect plants for signs of infection and promptly remove and dispose of any infected material.
