Sometimes it happens that an orchid gets sick. Most often this is due to poor conditions, improper handling and various parasites. Experienced growers recommend to inspect immediately at the time of purchase. Most of the symptoms can be identified visually. The main causes of core rot are pathogenic bacteria and fungi.
External manifestations
Rot is a disease caused by phytopathogenic fungi and bacteria. In the process of development, decay leads to the defeat of leaf blades, stem, roots, at a more advanced stage - to the complete rotting, drying out and early death of decorative flowers. Externally, it appears as dark spots near the base of the exotic. Over time, they tend to grow. Entails the yellowing and darkening of the leaves, and their further fall off.
The condition of the orchid in this disease:
- Weakness.
- Poor decorative quality.
- The duration of flowering is reduced.
- Growth stops.
- The turgor is lost.
What are the consequences?
Since the flower has one growth point, you need to ensure that it does not rot. Indeed, after its death, development will cease, and the plant will subsequently die. Also, if the heart has rotted, the orchid loses its foliage. It becomes soft, loses elasticity, and then completely falls off. Next comes the root damage.
With a high humidity in the room, infected areas of the flower overgrow with spores of rot, and this is fraught with throwing the disease on other pets. Therefore, it is very important to know what to do if the orchid is rotting and to take urgent measures to eliminate the ailment. Only timely help will give orchids a second chance for life. In the later stages will not save anything.
What is the cause of damage to the trunk?
- Mechanical damage.
Rot can be formed as a result of the fall or injury of a part of the flower. If time does not provide assistance, that is, to treat the damaged area with an antiseptic, the result will be rotting of the stem.
- Frostbite.
Novice flower growers carelessly produce watering. They make a warm shower for the orchid, but at the same time they forget about the water that accumulates in the sinuses. In the summer, there is nothing dangerous about it. Due to the hot weather, the water will evaporate quickly.
Important! But in the winter, the flower is threatened with frostbite, especially standing on a stone window sill. The fluid will not evaporate, but will remain in the sinuses for a long time.
- Fungal and bacterial infections. In case of violation of the indoor microclimate, infectious diseases occur. It is also possible if the quarantine was not respected. As soon as an infection was detected, the flower must be immediately isolated from the rest of the plants so that the ailment does not spread to them.
How to determine that the plant has a rotten stem?
- The foliage becomes less elastic, has a not so bright color, loses a tone.
- At the base of the sheet you can see a brown tint.
- Green mass quickly dies.
- Dark spots on the trunk and neck.
- Green traces of sporulation are visible on the walls of the pot.
- The upper part of the flower is loose and unstable.
The better to handle?
Chemicals
One of the most effective drugs are fungicides. These funds are intended for the elimination of pathogens of fungal diseases in plants. The composition of fungicides may include the following components: mercury, manganese, organic substances, copper, aldehydes.
The most famous drugs:
- Fitosparin-M actively destroys fungus and bacteria.
- Quadrix - has a wide spectrum of action, azoxystrobin is taken as a basis. It is used for prophylactic and therapeutic purposes.
- Copper sulfate - made on the basis of copper sulfate, the result is visible after only 3-4 hours.
- Bordeaux mixture - prepared on the basis of copper, and also includes lime, which lowers the acidity of the soil.
- Mikosan - well helps in the initial stage of the disease, stimulates the immune system.
Folk methods
With small areas of damage at the initial stage of the disease, it is possible to use folk remedies:
- Iodine solution. 5-7 drops of a substance are diluted with 5 liters of water and a flower is sprayed once a week.
- Mustard Infusion. It will take 5 liters of hot liquid, in which you need to dilute 50 grams of mustard powder. Then the solution should be infused for at least 2 days. Before you apply, diluted 1: 1 with water.

Although natural products are harmless and easy to prepare, they can only help at the onset of the disease.
