Diseases and pests of indoor plants: protection and treatment
Indoor plants are susceptible to various diseases. These diseases are the result of exposure to adverse environmental conditions, as well as the result of inappropriate care. It can be: excess humidity or dry air, too high or too low temperature, lack of fertilizing or excess, the quality of the soil mixture does not meet the required, not suitable capacity, etc. Most of the diseases are not transmitted to other plants. Sometimes the problem is that outlets sell greenhouse plants, which are sometimes difficult to adapt to the conditions of modern apartments, as a result of which they may develop poorly or drop leaves, indicating that the conditions for this plant are not entirely suitable. If such a precedent holds, then the plant needs to be removed from the pot and examined the roots. If the root system is damaged, the plant will have to say goodbye, otherwise, it must be transplanted and experimentally established, what is the reason. Perhaps there is little light for this plant or it lacks nutrients. The object can be fed and moved to a more lighted place. If the plant before this stood in a lit place, then it should be moved to partial shade or shadow.
In any case, it is necessary to check how effective the drainage is and whether it exists at all. In its absence, you need to transplant the plant in accordance with all the rules. Many indoor plants do not tolerate or poorly tolerate temperature fluctuations, as well as the presence of drafts. This is an important factor that should be taken into account when keeping indoor ornamental plants or flowers.
Dry air, especially in winter, when the heating season begins, can cause significant harm to plants. It can cause thrips and a spider mite if preventive measures are not taken.
Watering plants is carried out with water at room temperature and only soft (rain or melt) and only settled.

Common indoor plant diseases
Leaf stain fungi
As a rule, plants are affected, for which poor quality care is performed. Basically, this affects: camellia, anthurium, certain types of palm trees and orchids.
Such defeats characterized by the appearance of spots on the leaves, and not large sizes. If no measures are taken, then these spots grow, and the leaves begin to die.
Ways to fight the fact is that the affected plants are not sprayed with water, and the affected leaves are removed.
This common disease can develop in warm and humid conditions, which may be relevant when growing plants in greenhouses.
Symptoms appear in the form of the appearance on the leaves of plants such as palm trees and ficuses, dark brown streaks.
Methods of struggle with such diseases it comes down to the systemic treatment of plants with fungicides and the destruction of damaged leaves. In addition, for several weeks, watering and spraying of plants is stopped.
This type of disease appears in dry and warm air. At the same time, various types of plants can be found and various types of fungi. In other words, the fungi appearing on begonias cannot appear on the rose. Plants such as hydrangea, cretone, begonia, Kalanchoe, cyclamen, chrysanthemum, roses, and uzambers are affected by powdery mildew.
Appearance This disease is characterized by the presence of a white, easily spreading coating. This plaque can be found on leaves, buds, young shoots and flowers.After that, the affected areas begin to blacken and die off. The fungus can quickly switch to other plants of the same species.
Methods of struggle consist in isolating the diseased plant and destroying the affected areas, after which the plant is treated with the appropriate chemicals.
It develops well in a moist, but at the same time cold environment. It can affect certain types of plants, such as primrose, calceolaria and gloxinia.
Symptoms serves as the appearance of an indelible white coating on the lower part of the leaves. To prevent the onset of this disease, Do not overmoisten the soil, as well as the air around the plant. Plant disease should not be sprayed with water. Since the fungus lives inside the leaf tissues, it makes no sense to spray the plant with various drugs.
This disease manifests itself in the stem cuttings of many plants, but pelargonium suffers most of all. It can occur as a result of high humidity or excessive compaction of the soil, which prevents the free passage of moisture.
Symptom the appearance of such a disease is the blackening of the base of the stem, which indicates the defeat of its fungus Botrytis.
The affected stalk should be removed immediately and a new one planted, while making sure that the ground or substrate is not so wet, and the stalk should not be covered with film or glass.
The gray rot fungus is able to appear in conditions of moist and warm air, as a result of the incorrect location of the plant, since it is weakened. Most affected by plants with thin and soft leaves
It can be chrysanthemum, gloxinia, cyclamen and others.
Appearance This disease can be detected by the appearance of gray mold on the stems and leaves, which can rise into the air when strong air currents appear. The consequence of such a lesion may be the darkening and dying of the affected areas.
Methods of struggle with this disease, you need to carefully and carefully remove the affected area. After this, the plant is not sprayed and less often watered, and the room is regularly ventilated.
This disease appears on plants such as rose, fuchsia, pelargonium, etc.
Symptoms rust can be identified by the appearance of brown or orange wart-like pustules located on the upper side of the sheet. They can be easily pried off with a fingernail, and light spots appear in their place.
If the plant is damaged by rust, it is better to destroy the entire plant, and not just the affected parts. If the plant is very rare and expensive, then you may need to treat the plant with a systemic fungicide.
The appearance of such a fungus contributes to its rapid spread, which leads to the death of the plant. After that, the entire plant is produced, along with a pot and soil.
Appearance this disease can be determined by softening the stems or the entire crown, after which decay occurs. In this case, the whole plant can be affected.
Methods of struggle very conditional and it is unlikely to save the plant, even at the initial stage of the disease.
Preventive measures are to keep the plant in normal conditions, while trying not to “flood” the plant, maintain an appropriate temperature regime and regularly ventilate the room.
The basis of this disease are fungi that affect the base of the stems, as well as the roots of the seedlings.
Symptoms such diseases are changes in the structure of the stems in the region of the root system, as a result of which they begin to rot, after which young plants die.
Prevention Methods such diseases lie in the plane of observing the golden rules for sowing seeds: seeds are planted in sterile soil, not very thick and with optimal watering.As soon as the disease begins to manifest itself, the affected young plants are immediately removed, and the rest are moved to a cooler place, where the room is regularly ventilated.
The cause of the manifestation of this disease can be both fungi and bacteria.
Manifested it appears on the leaves of dieffenbachia, citrus, dracaena and other plants of weeping brown spots. If no measures are taken, then these spots will grow and merge into one whole spot, as a result of which the whole sheet will be affected.
Methods of struggle include fungicide treatment, as well as burning of affected leaves, after which the plant is no longer sprayed and watered for several weeks.
This disease is a consequence of waterlogging of the soil in low light conditions.
Manifested this reaction by the appearance of dense cork growths on the back of the leaves.
It is better to remove diseased leaves, since they will not take their original form, and the plant itself should be moved to a more illuminated place with a decrease in watering activity. In this case, new leaves will grow, completely healthy.
Succulents, palm trees, begonias, senpolia, etc. are unstable to such a disease.
Symptoms appear in the form of yellowness appearing on the leaves or stems, after which the plant begins to fade. Then the affected areas darken, as a result of which the plant dies. This disease appears as a result of fungal root disease, which develops as a result of severe soil moisture.
Fight the root rot is possible only at an early stage of its detection and only by the surgical method, which consists in the fact that the plant is released from the pot and the roots are washed, after which, with a sharp knife, all affected roots are cut out. After that, the plant is transplanted into a new pot with fresh substrate. A pot with a plant must be placed in a lit place, but without direct sunlight. As soon as new sprouts appear, the plant must be watered, but not in large doses, so as not to overmoisten.
The black appearance of the fungus may appear in places where aphids, whiteflies or mealybugs leave behind sweetish secretions.
Symptoms appear in the form of not a beautiful plaque, which does not pose a danger to the plant itself, but closes the leaf surface from the passage of sunlight, which greatly inhibits the plant.
Wrestling with a black coating consists in mechanically removing it with wet rags, and rinsing the places with fresh warm water. To avoid this, it is necessary to timely treat plants from pests.
Plant viral diseases
Plants, as a rule, become infected at the stage of their propagation in greenhouses, after which they enter the distribution network.
Symptoms may be different, but basically, infections also slow down the development of the plant or the plant does not develop properly: the stems are bent, and growth is inhibited. Dots or stripes of various colors may appear on the leaves and stems of the plant.
Methods of struggle with such a disease does not exist, since the reason is not known, therefore, it would be better if the plant is simply thrown away.
