Diseases of plants caused by bacteria

Diseases of plants caused by bacteria are very often easily confused with other diseases. Bacterial diseases can have differentmanifestations similar to the defeat of flowers fungi or viruses. Unfortunately, there are currently no effective means of combating bacterial diseases of plants. And existing control measures are not always effective. The fact is that pathogenic bacteria enter the body of plants through damage or the slightest holes in the leaves. Throughout the plant, bacteria spread through conductive vessels. It is the reproduction of bacteria in the vascular system of flowers that leads to the development of various plant diseases.

Bacterial rot

Do not forget that bacteria can spread on the tissues of plants. In this case, different bacterial decay. Most often, such diseases of plants can beTo observe flowers with juicy fleshy leaves. Bacterial rot often begins with the root system of the plant, gradually moving to the root neck. But also the plant can begin to rot and from leaves or stems. The cause of bacterial decay is usually the wrong condition of plant maintenance: excessive application of nitrogenous fertilizers or waterlogging of the soil.

Bacterial spotting and wilting

The development of bacterial disease of plants can also indicate the appearance spotting. In contrast to fungal lesions of leaves,Stains caused by bacteria do not have clear boundaries. Such spots grow very quickly in size, and the leaf dries and turns yellow. Wet conditions of plant maintenance only contribute to the rapid spread of the disease.

Bacterial wilting is accompanied by loss of a common plant turgor. First, this disease of the plant appears only on the tops. But soon the whole plant becomes very sluggish. Such wilting can also cause fungal diseases of plants. But unlike fungi, bacteria multiply in the vascular system of the plant, and they delay the flow of water. The life activity of bacteria is also accompanied by abundant release of toxic substances. To distinguish bacterial wilt from late blight, it is enough to look at the cutoff section. For late blight, the presence of a brown ring of vessels is characteristic.

Bacterial cancer

Very often on healthy plants, one can observe abnormal compaction and thickening of tissues. They are very similar to tumor growths. This disease of plants is called bacterial cancer. More often such bacterial diseases of plants are found on begonias, Kalanchoe, oleanders and succulent milks. Bacterial cancer is difficult to notice, because the tumors appear on the roots and root neck. With very rapid progress of the disease in the development of plants, there is a delay in growth. In the future, the plant dies.

Most often, weakened plants suffer from bacterial cancer: small tumors begin to appear on themthe size of a couple of millimeters to a few centimeters. Over time, tumors turn into sores that never heal. In the middle of ulcers, one can observe the accumulation of mucus, the product of the vital activity of bacteria. If on such ulcers you notice small points of sporulation of black color, then the disease is caused by a fungal lesion of the plant.

Any bacterial disease of plants is easier to prevent than treat. Therefore, be sure to disinfect the land andinventory that you use. If you touched a sick plant, always disinfect your hands with alcohol, so as not to transfer bacteria to healthy flowers. When transplanting plants into old pots, be sure to fill them with boiling water from the inside.

Infected with bacteria, flowers can be saved only at the initial stage of the disease. The diseased parts of plants are removed by capturinga small part of a healthy tissue. After each cut of the plant, the scissors or knife should be disinfected with alcohol. When all the diseased areas have been completely removed from the plant, the flower should be sprayed and poured with a Bordeaux mixture or any other preparations containing copper. If such measures did not help the plant, it will have to be burned. The pot, in which the flower grew, should be well scalded with boiling water.
