Due to the presence of chlorophyll in all plants there is a green color of the deciduous plate. However, it often happens that even yesterday the green leaves suddenly begin to lose their color. This is due to a lack of chlorophyll, and the disease of plants itself is called chlorosis.
How does chlorosis develop in plants?
The sign of the disease is the "burning out" of the leaf plate. " At first it only becomes a little lighter, but in time it can become completely yellow. At the same time the drying of the tips begins, and perhaps even the dropping of the foliage. The ability of the plant itself to reduce photosynthesis. Young leaves that appear are no longer so large.
Depending on which element is missing, the external signs of chlorosis may have specific features.
Causes of chlorosis
The most common sources of plant diseases are:
- the presence of diseases (viral or infectious);
- lack of individual microelements in the soil;
- increased acidity of the soil, as a result of which plants simply can not "get" from it nutrients;
- stagnation of water in the root system due to poor drainage, which also does not allow the assimilation of substances.
In case the cause of chlorosis is other diseases, it will be very problematic to save green pets.
Common types of chlorosis
In the suburban areas most often there are such types of plant diseases as chlorosis:
Iron chlorosis is caused by a lack of iron. Leaves in the upper part of the plants become yellow almost completely, only veins remain green. Treatment: simultaneous use of leaf and root dressings with iron preparations. For spraying on the sheet, a solution of iron sulfate works well. For watering under the root, you can prepare a chelated form of iron-containing top dressing: po, h. l. citric acid and ferrous sulfate dissolved in 1 liter of boiled chilled water.
To prevent disease, it is necessary to feed the plants with "Gilea-antichlorosis" fertilizer.
Of the traditional methods of preventing iron chlorosis, one can single out the use of rusty nails - they are buried in the soil when planting vegetables, flowers, trees, bushes and other plants.
To acidify the soil, you can dilute the citric acid (at the tip of the knife) in 1 liter of water and water the plants every two weeks.
Magnesium chlorosis is manifested in the form of yellow spots on the leaves in the lower part of the plants. For treatment, it is recommended to use calimagnesium or magnesium sulfate.
