Many housewives love to grow orchids in their homes. But sometimes on these flowers you can see a lot of sticky drops. Today we will talk about why they appear and how to properly treat indoor plants.
What it is?
Sticky liquid stains, as a rule, cover leaf blades (both above and below), young shoots, stems and branches of orchids. They are called non-flowering nectarine. They should not be confused with the natural formation of nectar, which cannot harm flowers.
Reasons for the appearance
There are various reasons why sticky drops form on orchids.
- pest activity;
- improper care;
Often on orchids you can see sticky drops due to the appearance of ticks and aphids on them. Most often in this case, you can find on the plants and small dots on the outside and back of the leaves, on the trunk, on the flower shoot (these are small insects that have fallen into the liquid). In this case, the greatest amount of plaque appears in the leaf area.
Sweet bloom can appear on the flowers due to the use of too much fertilizer. If the feeding is adjusted in a timely manner, the drops themselves will gradually disappear.
With an excessive amount of fertilizer, the flower should be transplanted immediately, regardless of whether it is currently blooming or not. If this is not done in a timely manner, the orchid may die.
Especially carefully you need to handle dressings containing phosphorus, nitrogen and potassium. After all, they, along with mineral fertilizers, can significantly increase the metabolism of a plant, which will lead to the formation of a layer of mucus on it.
Excessive watering of orchids can also be harmful. Therefore, you need to carefully monitor the amount of water for such flowers. Sometimes sticky spots may appear due to the natural process of formation of flower nectar. In this case, the liquid will not do any harm to the plants.
To determine the level of moisture in the earth, you need to inspect the soil. If he began to clump or lose its aeration properties, then the plant should be transplanted immediately. The same is done with the formation of white mold or in the presence of an unpleasant odor.
It is necessary to monitor the temperature, lighting in the room where the orchids are. They require good lighting, but they can not be placed in direct sunlight. Often, a hygrometer is placed next to the plant. This device is designed to control temperature changes in the room.
Orchids can often get powdery mildew, which is a common fungal disease. It arises from small spores that are easily carried through the air.
With this disease, in addition to copious sticky fluids, large dots of white color may also form. Together with them, a gray coating may appear on the leaf blades.
Currently, there are a large number of ways to cure orchids and rid them of sticky plaque secretions.
- At first it is recommended to pay attention to watering . In the winter season, it should be significantly reduced. Indeed, due to the increased level of humidity, the infection will only develop.
- If the plants are covered with small insects, they must be removed. This can be done manually, after which it is recommended to pour the flowers with warm water. If the orchid is damaged by a mealybug, it is also necessary to treat it with a solution of a special preparation containing oil.
- Sweet nectar, which appeared on the leaves and on the trunk, is a product of the activity of the mealybug. At the same time, on the plates it will be possible to see the harmful insects themselves, which got into the liquid.
- Often, plants are affected by a scab. This insect can be easily identified by an almost transparent semicircular carapace. These parasites secrete a waxy substance that accumulates around them and eventually forms a protective film.
- If the flowers are affected by a tick, then you should first remove all damaged parts of the infected plant. After this, it must be transplanted, and the pot in which it was located should be thoroughly washed with clean water.
If the orchid was hit by a spider mite, a small amount of moisture can be seen on the surface of the leaf blades, which eventually turns into a sticky liquid.
In addition, today there are a huge number of different drugs that will help fight sticky spots.
- Alirin-B. Often, instead of watering, damaged orchids are soaked in containers with water and dissolved tablets of this drug (2 pieces).
- "Phosphamide . " This drug is diluted in water and orchids are sprayed with it only if there are few parasites on the plants.
- Mospilan. Such a tool is an insecticide. It should be used several times with an interval of ten days for the best effect.
- "Fitosporin." This drug is a universal remedy for the treatment of fungal infections in plants.
- "Purebloom". A similar tool is intended exclusively for indoor plants. Often it is used not only for the treatment of sticky plaque, but also for prophylaxis.
- Bordeaux mixture . It is a substance consisting of copper sulphate and lime, which copes well with bacteria on flowers.
- Quadrice. The basis of this drug is the substance azoxystrobin, which has a strong therapeutic effect. It can also be used for plant prophylaxis.
- "Fundazole". It is a fungicide (a substance that suppresses the development of fungal infections). Most often it is used against powdery mildew. Treat affected orchids several times with an interval of 3-5 days.
- Zircon . This drug is able to significantly increase the stress resistance of orchids. After its use, plants become less susceptible to rot formation, powdery mildew and bacteriosis.
- Trichodermin . It is a biofungicide. It should be used as a prophylaxis or in case of damage to the root system and soil treatment.
- "Topaz" . Such a tool is used specifically for fungal diseases. It is sold in small bags in the form of an emulsion. For the best effect, Topaz should be used with contact fungicides.
In addition, today there are a considerable number of folk methods to combat sticky plaque on orchids. So, you can treat the flowers with ammonia, hydrogen peroxide. These substances are used to wipe the affected areas of plants with cotton wool. With severe damage to colors, it is best to immediately use special chemicals. At the initial stages of infection, damaged parts can be treated with laundry soap, but after that it is necessary to use a chemical agent to completely eliminate the infection.
Sometimes, cinnamon is taken to treat such flowers. It is sprinkled with pre-treated infected areas of plants. If mold has formed in the pot, then you need to pour cinnamon over the entire substrate. Moreover, this procedure must be repeated several times with an interval of several days.
We must not forget that in some cases, the formed plaque can be harmless. After all, it can act as a protection against harmful insects, since such a sticky substance is a “trap” for them. Once in a liquid, insects will not be able to get out of it.
If over time, instead of small drops, whole sticky patches appear, then this means that the pathological process of the disease has begun. In this case, rusty, black or yellow spots may later appear on the leaves and stems. Also, over time, leaf blades can completely change their natural color. They turn red or yellow, and are completely covered with plaque and liquid.
To prevent the appearance of sticky fluid on the orchid, it is recommended that a series of preventive measures be taken periodically. So, you should use special granules of special polymers, which can be found in almost any flower shop.
In addition, today there are various vitamin cocktails for damaged flowers. They can be cooked even at home. Most often they are made with succinic acid, drops of zircon, glucose.
It is also necessary to monitor the amount of water for orchids. Indeed, excessive watering can lead to the appearance of fungus, bacteria. We must not forget that such flowers require good lighting. Otherwise, powdery mildew may appear.
It is necessary to conduct regular examinations of orchids. If the first liquid drops are detected, treatment should be started immediately. Also, the affected flower must be isolated from other healthy plants. As a prophylaxis, you can use the drugs "Actellic" and "Actara". In appropriate dosages, they enhance the immunity of such indoor flowers.
