Symptoms of bacterial infection in plants are much like the symptoms in fungal plant disease. They include leaf spots, blights, wilts, scabs, cankers and soft rots of roots, storage organs and fruit, and overgrowth. Bacterial spots: the most common symptom of bacterial disease is leaf spots.
Plants infected with bacteria will develop an area that looks dark, black and wet, with angular borders since bacteria struggle to punch through major veins in the plant. As bacteria move through the plant, they digest cells and leave the plant looking water soaked and mushy.
These include fire blight in fruit trees, bacterial wilt in banana, bacterial blight in rice and crown gall in many perennial plants. In some cases, the epidemics caused by bacteria can cause significant economic burden on crops (FAO, 2018).
Fungus diseases are common during wet, humid seasons. Bacteria are single-celled microscopic organisms. Some attack living plants and cause plant disease. Bacteria can be carried from plant to plant by wind, rain splash, insects and machinery.
Symptoms Caused by Bacteria
Plant pathogenic bacteria induce as many kinds of symptoms on the plants they infect as do fungi. They cause leaf spots and blights, soft rots of fruits, roots, and storage organs, wilts, overgrowths, scabs, and cankers (Fig. 12-4).
There are several signs that can indicate a plant is diseased, including changes in leaf color, shape, or texture; wilting or yellowing of leaves; and the presence of spots, blotches, or lesions on the plant.
Using bacteria-free seeds and then monitoring the plants in all their stages of growth can ensure better control over any bacterial disease that might spread. Such control can help gardeners and farmers grow better, healthier plants.

Plant diseases can affect plants by interfering with several processes such as the absorbance and translocation of water and nutrients, photosynthesis, flower and fruit development, plant growth and development and cell division and enlargement.
As a general rule, bacterial infections are easier to treat than viral infections, since the armamentarium of antimicrobial agents with activity against bacteria is more extensive.
Plant pathogenic bacteria cause many different kinds of symptoms that include galls and overgrowths, wilts, leaf spots, specks and blights, soft rots, as well as scabs and cankers. In contrast to viruses, which are inside host cells, walled bacteria grow in the spaces between cells and do not invade them.
Symptoms include chlorosis, necrotic spotting, marginal scorch, twisting, growth abnormalities, leaf or needle drop, dieback, general decline, and plant death. As with environmental factors, cultural factors can affect plant health in many ways and result in a wide range of symptoms.
Heat. Heating the soil is very effective and the soil can be used immediately after cooling, unlike chemically treated soil. Many plant pathogens are killed by short exposures to high temperatures. Most plant pathogens can be killed by temperatures of 140°F (60°C) for 30 minutes.
Using 3% hydrogen peroxide like Forsana, mix equal parts hydrogen peroxide with water. Water into soil or mist infected areas to kill bacteria and fungi. If the plant is sensitive or you are unsure, treat a test area first at least 2 days before treating the rest of the plant to check for a reaction.
Bacterial leaf spot symptoms typically have a more angular appearance than fungal leaf spot, with the spots bounded between the veins. Fungal leaf spots will cross veins. This is because the bacteria is inside the plant and cannot cross vein easily.
After a microbe, such as a virus or bacterium, enters our body without being stopped by our immune system, the incubation period begins. This is the period between infection and the first signs and symptoms associated with a disease. We then enter the prodromal period.
Legionnaires' disease is a flu-like illness caused by the Legionella bacteria that can live in potting mix and compost. It can lead to severe pneumonia and even death. Garden safely by being Legionnaires' aware.
