Many houseplant lovers are familiar with a flower called gloxinia. Gloxinia diseases with photos we will consider today. This tuberous plant has a shortened stem and velvety leaves. Funnel flowers have a beautiful color.
- standard with a height of up to 25 cm;
- compact with a height of 12.5 to 25.3 cm;
- miniature, having a height of 5 to 12 cm;
- microminiature up to 5 cm high.
The cause of its diseases can be fungi and pests. It is rather difficult to grow a flower of predominantly blue-violet and red-pink color.
Fungal Gloxinia Disease
Why does gloxinia not bloom? This question torments many gardeners. Gloxinia often get sick with various fungal diseases, in which the natural color of the leaves disappears and parts of the plant blacken. If the buds of a plant begin to rot, you can find several causes of this problem:
- excessive watering;
- acidic soil;
- excess nitrogen.
With abundant watering, it is enough to adjust it so that the earth is not excessively wet. With acidic soil, you need to transplant the plant with a complete replacement of the soil. Excess nitrogen may occur after nitrogen-containing fertilizers. It is better to feed complex fertilizers for gloxinia. They necessarily include nitrogen and potassium. In addition to these elements, complex fertilizers contain phosphorus and many other chemicals. If the wisteria tuber rots, you need to spray the plants with fungicide 2-3 times.
Why else does gloxinia not bloom? Of the diseases of fungal origin, it is worth noting anthracnose. Its symptoms are brown spots on the leaves. They gradually switch to shoots and to the trunk of the plant. In the end, this leads to their decay and destruction. Anthracnosis in gloxinia must be treated without fail. This disease can attack plants with mechanical damage. Increased humidity and acidity of the soil, the lack of phosphorus and potassium in it can also provoke the disease.
To prevent pathology, complex care is required: you need to spray the plant with copper chloride, cuproxate or oxychrome and feed it with fertilizers. Otherwise, with working equipment and with the help of various pests, the disease will pass to neighboring plants. Do not expose diseased specimens to the street in the rain. All work equipment should be disinfected after use. If the infection of the plant is very strong, then it is better to destroy the flower by burning. The initial stage of this disease is eliminated. The treatment is as follows:
- you just need to remove the diseased parts of the flowers with brown spots (leaves, stems, buds);
- spray the plant with fungicide 2-3 times with an interval of 2-3 weeks.
Another disease is ascochitosis. Its signs are the appearance of red spots with brown rims on the leaves of the plant. The spots may have a brown color. This can happen when air humidity rises. For treatment you need:
- completely remove all stained leaves;
- to prevent the spread of infection it is better to burn them;
- treat the diseased plant with Bordeaux fluid;
- after 7-10 days, repeat the treatment.
Instead of Bordeaux liquid, you can use copper sulfate, fungicides such as "Abiga peak" or "Vectra."
Phyllosticosis is a fairly common disease. Dark rounded spots appear on the leaves. Their middle is brown. The leaf grows, there are tears at the spots. When these signs appear, you must immediately spray the diseased plant. The treatment of gloxinia consists in treating them with preparations containing copper. It can be Bordeaux liquid, copper sulfate or copper oxychloride.
A few more fungal diseases
To diseases having a fungal nature, Septoria is related. It can be carried with raindrops and with the wind. Optimal conditions for the appearance of this disease:
- staying in a room with a temperature of 20-25 ° with a humidity of 98%;
- moisturizing leaves for a long time (up to 48 hours);
- low light level.
On the leaves of the diseased plant, spots appear that have a gray-brown color. Outwardly, they resemble rust. The leaves then begin to fall off. The stems dry and die off gradually. Buds may also suffer. It is recommended to treat the plant with fungicides such as Benomil and other or any copper-containing preparations. Treatment should be repeated after 7-10 days.
Late blight is a disease caused by fungi. It can spread through soil and equipment, through planting materials and rainwater. The causative agents of the disease are able to live in the ground up to 8 years. Blight occurs under the following circumstances:
- re-compacted soil;
- stagnation of water during irrigation;
- dense population of plants;
- the soil is poorly prepared;
- watering is done by rain water;
- too frequent spraying;
- humidity 80% and above;
- temperature changes from 10 to 22 ° during the day.
Signs of late blight are brown spots with a pale green border. The inner side of the leaves may be covered with plaque in the form of white mold. It is well manifested in wet weather. The leaves dry and die off when dry weather sets in. Stripes of dark brown color may appear on the stems. The plant withers. It’s very difficult to treat a patient with gloxinia. Chemicals do not help. Only proper prevention will be effective. It is necessary to water the plants with cuprosan. Polycarbocide and polymarcin can be used for this. Before planting gloxinia or when transplanting it, you need to sterilize the soil. Keep the roots of the plant well for 5 minutes in a suspension of captan. It is almost impossible to cure a diseased plant, so the only right way out is to burn it.
Gray rot also has its own characteristics. A white fluffy coating appears. It affects pedicels and petioles of leaves. The flower rots and dies. The reasons are the cramped arrangement of plants, increased humidity in the room, insufficient ventilation of the roots due to caked soil. You just need to provide moderate watering and add sand, perlite or vermiculite to the soil. These additives will provide quality root ventilation. In a room with gloxinia there should be no drafts. Fungicide disease is treated with an interval of 7 days.
Powdery mildew is a fungal disease. With him, all parts of the plant are covered with a bloom of white color, which quickly turns into powdery. The disease develops with heavy watering, with temperature changes, with dampness in the room. It is better to burn a completely infected plant right away. The initial stage of the disease can be treated with fungicides.
Save indoor plants from pests and diseases (video)
Pests are very harmful to flowers. The most popular type of gloxinia pest is thrips. These are insects that feed on plant juices. In the photo their individuals are perfectly visible. Their size in adulthood is up to 1.5 mm. Signs that pests have appeared are small dots of light color on the leaves of the flower. If they are found, you need to isolate the flower pot from other plants. After this, you need to treat gloxinia with insecticides such as Intavir, Fitoferm, Aktara, Aktellik or Karate. To completely destroy thrips, you need to carry out triple processing at intervals of 7 days. You can take photos to track the dynamics of treatment. Otherwise, the leaves turn black and fall off.
Conclusion on the topic
Gloxinia, due to abundant and very beautiful flowering, is very popular among gardeners.
This plant of artificial origin came to us from South America. It requires a special approach. It needs to be fed on time, remove dried leaves, make additives to the soil. Caring for her is quite complicated. If it is disturbed, the plant may stop blooming. We must not forget about the introduction of fertilizers into the soil for gloxinia. The leaves of a plant in a normal state only dry when it goes to rest. It usually happens immediately after flowering.
At rest, the tubers of the plant can be cleaned in the refrigerator. But special control and care is required, otherwise gloxinia from frozen tubers does not germinate. At the most careful observation, gloxinia does not wake up. It’s better to just put the flower in a darkened cool place. The plant sleeps 3-4 months. Then small leaves appear on the tuber, the flower stretches, buds appear. During this period, special attention should be paid to caring for him. Otherwise, you can not wait for the flowering period. Beautiful buds of this plant can be seen in numerous photos in special stores and magazines.
