Gloxinia disease overview with photos and treatments

Gloxinia is a delicate ornamental plant, characterized by colorful and long flowering. But various diseases and pests can spoil the appearance of a flower or lead to its death.

This can be prevented if you know the most common diseases, and direct all efforts to prevention.

In the article, we will examine why gloxinia withers and dries, as well as other ailments and how to bring it back to life. Also watch a useful and informative video on the topic.

Plant features

Gloxinia - a spectacular flowering houseplant. Its peculiarity is in lush flowering, and with careful care and favorable conditions, up to 15-20 buds can form on one flower. Gloxinia is a perennial herbaceous crop native to Brazil. Her dimensions are small: the height of an adult plant is 15-30 cm.

On a note. Gloxinia tubers live 3-4 years, but as they age, the flowers become less beautiful.

The leaves reach a length of 15-25 cm, oval, covered with a fluff, with scalloped edges, located by a rosette. Gloxinia blooms from April to August. On long peduncles large, “gramophone” flowers are formed. Their diameter is 10 cm. The color can be pink, purple, white.

Fungal diseases and methods for their treatment

Below we will talk about the main fungal diseases that affect pelargonium, as well as what and how can be done for treatment.

Late blight

This is the most dangerous disease, since it is impossible to cure it. Late blight develops due to increased humidity and temperature jumps of 9-20 degrees. For late blight, the following symptoms are characteristic:

• general wilting of the plant;
• the formation of brown spots on the leaves;
• white plaque on the inside of the sheet.

The development of infection occurs everywhere, and spreads rapidly. The affected bush cannot be cured, it is removed along with the ground. For prevention, spraying with such drugs is carried out: Kuprozan and Tseneb (40 g per 10 liters of water).

Powdery mildew

Attention! This disease is formed against a background of increased humidity and temperature changes.

For him, the formation of a whitish cobweb plaque is characteristic. Infection can occur with soil or through inventory. Remove the affected elements of the plant, and treat the flower itself with fungicides:

1. Bayleton.
2. But.
3. Quadris.
4. Rayok.
5. Coming soon
6. Tilt.

Downy mildew

it fungal disease affects the upper part of the plant. Sick leaves frown, begin to curl into a tube (read about other diseases of gloxinia leaves here). When the leaf petiole is affected, it dries and falls away. Blurry spots form on the outside of the leaves. They can be of various colors:

• yellow;
• reddish brown;
• purple.

The following causes affect the development of downy mildew:

• low air temperature at night;
• heavy acidified soil;
• high humidity.

There are several ways to treat a flower.:

1. Treatment with preparations with a copper compound:
   • Thanos;
   • Topaz;
   • Vectra.
2. At the beginning of fruit formation, spray the plants with Gamair (with an interval of 15 days).
3. Treatment with iodine milk. Combine 1 liter of non-fat milk with 9-10 liters of water, add 10-14 drops of 5% iodine.
4. Processing infusion of ash. Pour 200 g of ash with 3 l of boiling water. Bring the volume of water to 10 liters, filter and process the plants.

Anthracnose

Reference. The disease is characterized by the formation of small brown spots. First, they hit the leaves, and then move to the stems and buds.

The disease is characterized by rapid spread, so that the affected plant is removed.

For prevention, treat the flower with the following drugs:

• copper oxychloride;
• Cuproxate;
• Oksikhom.

Ascochitosis

The disease is accompanied by brown or red spots on the leaves, and along the edge they have a brown border. The reason for the appearance is increased humidity in the room. Ascochitosis is a dangerous disease. All affected leaves must be removed and burned.

To save the plants, conduct treatment with copper sulfate or with drugs such as Vectra, Adiga-peak. After 7-10 days, repeat the treatment.

Septoria

Fungal disease occurs against the background of increased humidity, insufficient lighting and prolonged contact with water. Stains form on the leaves, which look like rust. The stem, leaves and buds quickly wither and dry. The treatment is based on the use of fungicides: Maneb, Benomil.

Phyllosticosis

The disease develops due to increased humidity. Dark rounded spots form on the leaves, brown in the middle.

As the disease progresses, tears are added to the spots. If you find the first signs, you need to dry the plant.

Then carry out processing with such drugs:

• Bordeaux fluid;
• Oxychloride;
• Copper sulfate.

Fusarium

It occurs due to improper irrigation regime and contaminated soil. The leaves of the plant wither and twist, acquire a brown color. Cracks and stripes of dark color are visible on the shoots.

Treatment consists of the following steps:

1. Soil replacement.
2. Wash tubers and roots in a weak solution of potassium permanganate (5 g of potassium permanganate in 1 liter of water).
3. Transplant the flower into a fresh substrate. It should be light and nutritious (on how to properly transplant a flower, read here)
4. Carry out a fungicide treatment.

Gray rot

Reference. It occurs with insufficient soil ventilation and high humidity.

The leaves and stems are affected by a gray coating. Treatment includes the following:

1. Reduce room humidity.
2. Add some sand or vermiculite to the soil. This will provide good ventilation to the roots.
3. Reduce watering.
4. Remove rotten leaves.
5. Treat with fungicides.

What to do with other ailments?

Of other diseases, the plant is most often threatened with virosis and bacteriosis. We will find out whether it is possible to somehow help in these cases.

Viroses

This disease develops against the background of viruses that penetrate insect pests or with fungal spores. On leaves and flowers spots, stripes and dashes are formed. This disease is not amenable to treatment. Remove the affected plant from the pot and burn.

Bacteriosis

Bacteria can be introduced with untreated equipment, a pot, or non-sanitized soil. They defeat:

• a tuber;
• buds;
• the kidneys;
• leaves;
• to the stems.

Bacterioses are not treatable. When infected, you need to get rid of the flower. Prevention includes regular use of Zircon and Epin. These drugs stimulate plant immunity.

Pests and how to eliminate them

Pests cause no less damage to plants compared to various diseases. Consider representatives of such a fauna.

Spider mite

These pests appear due to insufficient humidity and dry air. Settling on one flower, they form a colony of about 100 individuals. The plants feed on the juice, which is why light spots form on the leaves. Over time, they brighten and dry.

On a note. Prevention of the appearance of a spider mite is reduced to a timely inspection of the plant.

Humidity in the room where the flower is located increase. To combat the pest, the following measures are provided:

1. Processing plants with Fitoverm, Intovir preparations.
2. Soil treatment with drugs that destroy the larva shell - Aldikabr, Temik.
3. To increase humidity, spray the plant and place it in the greenhouse.

Repeat similar events in 10 days to eliminate stronger individuals. Cyclamen tick These small pests inhabit the lower part of the leaves. With damage, the plant stops growing, and all its parts are deformed. At the edges, the leaf is curled down, and the stem is twisted. The buds wither and crumble, and the blossoms take an irregular shape.

The upper part of the shoots dries, acquires a brown color. When there are multiple individuals, their colonies look like dust accumulation. To combat the cyclamen tick is carried out:

1. Processing plants with Fitoverm, Intovir preparations.
2. Soil treatment with preparations destroying the larva shell - Aldikabr, Temik

Thrips

From other pests, thrips are distinguished by an elongated body. Some individuals populate the buds of plants and live there all their lives, while others prefer leaves. They feed on juice or nectar. In the presence of thrips, light spots are formed on the leaves of the flower - stripes or strokes. They merge over time.

This leads to wilting of flowers and leaves. They dry up and fall away. Treatment comes down to the following activities:

1. Inspection of the flower. If a colony is found on any one plant, then remove it from the rest.
2. Disinfect the location of the flower.
3. All plants that were nearby should be treated with such preparations:
   • Fitoverm;
   • Akletik;
   • Vermitek;
   • Intavir.

   To breed them according to the instructions. After 10 days, repeat the treatment.

Shield

You can recognize the scab by the presence of a sticky pad on the leaves. The pest spreads throughout the plant, affecting the stem, leaves and buds. He eats the juice of the culture, depriving it of trace elements. The leaves turn yellow, dry out, the growth of young shoots stops.

Attention! If treatment is not started on time, then gloxinia will die.

The treatment consists of the following events:

1. Cleaning plants from insects. Take a cotton pad and moisten it in miennoy solution (1 liter of water and 20 g of soap). To process with a solution all parts of the plant, removing the scale.
2. Spray a flower with an insecticide - Bankol or Actar. Cover with foil for 1 hour. To get the maximum result, re-process after 3-4 days.
3. Clean infected plants for quarantine and thoroughly wash the infection site with a soapy solution.

Whitefly

This insect has a white color, so it's easy to notice. Of particular danger are growing individuals. Pests feed on the juice of leaves and stems.

Adults leave leaves of their vital products on the leaves. This creates unfavorable conditions for photosynthesis. The leaves begin to rot, the stem changes, the buds are not tied.

Pests can be introduced through the soil, other plants, by a stream of air from other diseased flowers. If infection has occurred, then the following chemicals are used to control pests:

• Vertimek CE;
• Actellic CE;
• Admiral
• Kinmix;
• Oberon.

They act on the intestines of the parasite, causing its death.

Mealybug

This pest leaves a sticky layer on the leaves. Because of this, they turn yellow and fall. The growth of shoots stops. Mealybug is a parasite that looks like an aphid, only he has a white body. Insects feed on the juice of leaves and flowers. The specimens are quite fertile.

Adult parasites populate not only leaves, but also roots, flower capacities.

Reference. Mealybugs love dry and warm places, so the main reason for their appearance is low humidity in the room.

Treatment includes the following activities:

1. Wipe the affected parts with a cotton swab dipped in alcohol. and wait 30 minutes, it will be easier to remove pests.
2. Perform treatment with the following drugs:
   • Karbofos;
   • Tsvetofos;
   • Intavir;
   • Decis;
   • Fosbezid;
   • Actellik.

   To insecticide stick better to the protective shells of insects, add 20 ml of dishwashing liquid.

The most common problems and ways to reanimate a flower

Gardeners often wonder about the etiology of plant ailments and methods of dealing with them. We will study the causes of various problems and how to solve them.

Peduncles turn black

Why can the flower stalks turn black:

• excessive waterlogging;
• too acidic reaction of soil pH;
• excessive amount of nitrogen-containing fertilizers.

You can fix this problem as follows:

1. Change the ground, adjust the watering.
2. In order not to over-saturate the soil with nitrogen, use complex formulations containing even phosphorus and potassium.
3. Carry out the treatment with Fitosporin, Maxim. This will save the peduncle of gloxinia from decay.

Why does the stem stretch?

Many flower growers do not know why this happens and what to do in a situation where the stem of gloxinia is very long. To solve this common problem, first of all, it is important to consider that this happens for two reasons:

1. Bad light. Gloxinia is a photophilous culture and in insufficient light begins to lengthen the stem. To solve the problem is simple - install a flower pot in a more lighted place.
2. The stem is drawn from those plants that were not sent to "rest". It is necessary to perform pruning, otherwise elongated shoots will not give a long and beautiful flowering.
3. Feature of a grade. Nothing can be done about these, you need to carefully monitor the lighting. Under varietal lengthening, a lack of light may be hidden, which can affect the splendor of flowers.

Crochet flower

Important! If the gloxinia flowers began to curl, then this indicates that the wintering culture was too cold or watered too often.

Problems can affect the development of:

• too low temperature;
• drafts;
• poor soil, not enriched with minerals.

Complex fertilizers containing phosphorus, potassium and nitrogen will help to cope with the problem. Set the flower pot to the south side, adjust the watering.

Home Care Organization

Most often, gloxinia rots due to non-compliance with agricultural regulations. Consider what this plant needs for health.

Lighting

Gloxinia prefers bright but diffused light. For her, direct sunlight is unacceptable. A suitable place for placing pots are windows that face west or east.

Plants growing on the southern windows need additional shading, as direct rays of the sun will lead to burns on the leaves.

Temperature

Note! Since the plant has pronounced periods of active growth and dormancy, it is important to observe the temperature regime.

In the summer, in the room where gloxinia grows, maintain a temperature of 20-22 degrees. At night, it is permissible to lower the temperature to 18 degrees. In winter, during the rest period of gloxinia, indicators of 10-14 degrees are considered comfortable.

Humidity

Humidity should be between 70-80%. If water gets on the leaves and flowers of gloxinia, they will begin to rot. To humidify the air, place the pot on a pallet filled with wet expanded clay or pebbles.

The soil

Gloxinia is demanding on the soil. Plant a plant in special soil mixtures:

• Violet;
• Begonia;
• Saintpaulia.

When preparing the substrate yourself, use the following components:

• sheet earth - 2 parts;
• peat land - 1 part;
• river sand - 1 part.

Drainage is mandatory for the flower. Suitable for him:

• expanded clay;
• washed eggshell;
• Styrofoam.

Other important preventive measures

Humidify the earth as it dries. In this case, pour water into the pan or into the edge of the pot. During the growing season, watering should be plentiful.In this case, excess water can destroy the flower, and it will rot. After watering, the pot is placed on wet gauze. Then excess moisture is absorbed. To moisten the soil, use settled water at room temperature.

Gloxinia requires periodic fertilizing with fertilizers for flowering indoor plants. Deposit from April to August every week. Apply ½ dosage indicated in the instructions (Giant, Gumi). During rest, feeding is not necessary. Read how to properly water and feed gloxinia here.

So, gloxinia is a rather fragile and delicate houseplant, which, if the rules of agricultural technology are not followed, can infect pests and diseases. The task of the grower is to timely detect the lesion and urgently take rehabilitation measures.
