Plaque on plant leaves


White bloom on the leaves of garden or indoor plants does not just spoil the appearance, it is also a sign of some kind of disease. It will be possible to get rid of this plaque only if the reason for its appearance is correctly determined. And there may be several reasons.

Powdery mildew

Most often, plants are infected with this fungal disease, which causes the appearance of white bloom. To confirm the diagnosis, lightly rub the surface of the leaf. If it is powdery mildew, then small pellets of very small filaments of mycelium will remain on the fingers. It is recommended to fight a fungus from the powdery mildew family with sulfur-based fungicides or proven folk remedies and recipes.

  • This recipe is recommended to be used only at the initial stage of the onset of the disease, then its effectiveness will be very high. Plants must be treated with a manganese solution prepared from 10 liters of water and 1.5 g of manganese. Spraying should be carried out immediately after the end of the rain.
  • Treatment of plants with a solution according to this recipe should be carried out 2-3 times every 7-10 days. It is necessary to prepare an infusion of mullein. Three parts of water is mixed with one part of mullein and left to infuse for 72 hours. After three days, the infusion must be filtered and 3 times more water must be added to the resulting volume.
  • Spraying with this solution gives a good effect after the second application. You need to mix 7 liters of warm water, 3 liters of milk whey and 1 teaspoon of copper sulfate.
  • The most popular folk recipe is the treatment of plants with onion peel infusion. It is prepared from 10 liters of water and 200 g of onion husks. The composition is brought to a boil, and then infused for a day.

Downy mildew signs are yellow spots on the upper side of the leaf and a gray-purple bloom, as well as white bloom on the underside of the leaf plate. Copper preparations will help to get rid of this disease.

Mold

Mold on plant leaves is a fungal disease that appears most often from repeated excessive moisture in the soil during watering, frequent and abundant spraying, as well as high humidity in a room with indoor flowers. Mold is a fibrous or woolen-looking formation on the surface of sheet plates that resembles a small layer of dust. The fungus develops very quickly and is capable of destroying the entire plant in a short time. That is why it is necessary to take urgent measures to destroy it. At the initial stage, all damaged leaves are removed and the culture is treated with antifungal agents.

Gray rot

When this fungal disease appears on the leaves, stems and petioles, a fluffy coating of a gray tint appears, which eventually turns into rot. Gray rot can destroy a flower completely in a short time. It is very important to notice its first signs and immediately move the plant away from other specimens. If half of the plant or most of it is infected, then it will have to be destroyed, since there is no cure for this disease yet.

Fungal diseases appear where all conditions are created for them. It is very important to remember that when growing indoor plants, you must not violate the basic rules of care and maintenance. For example, you need to strictly observe the frequency and volume of watering, regularly ventilate the room. You cannot put flower pots with plants very close to each other, they need free air passage.

Plaque of black, red and other colors

It happens that raids of red, black and various other shades appear on indoor plants. They all signal the appearance of some kind of health problem.

Rust - a fungal disease, the signs of which are plaque on the back of the leaf surface of a yellow, orange or brown hue. After a while, the leaves covered with such a bloom dry out. Rust appears in a damp, cool room with a temperature of 10 to 20 degrees Celsius and a high level of humidity. Experienced growers recommend first stopping the growth of the fungus with high temperatures. To do this, cover the flower with a dense plastic bag and place it near a battery or heating device. And then, for a month, carry out the fungicide treatment once a week. During the "treatment" period, it is not recommended to spray the flowers with plain water, as it is an excellent place for spores to ripen.

Black bloom - a fungal disease that most often affects palm and citrus crops, as well as camellias and azaleas. Black sooty mushrooms like to settle on a sticky leafy surface, which becomes so from the presence of harmful insects (for example, worms, thrips and aphids). The upper and lower parts of the leaf plate seem to be sprinkled with black powder or covered with a thin black crust, which prevent the flower from breathing and fully developing. Photosynthesis also slows down.

To restore the decorativeness of indoor crops and return them to a healthy appearance is possible only by completely destroying the pests. After all, it is the parasitic insects that leave traces of their vital activity on the leaves, which attract the fungus with their sticky structure. Such a sweetish bloom becomes an excellent breeding ground for a dangerous fungus. When the pests are gone, each leaf should be washed with a soft sponge dipped in warm water.

Features of the disease

The fungus lives in almost all pots with indoor plants, but its pathogenic activity is far from always manifested. If a green pet is kept in comfortable conditions, provided with all the necessary micro and macro elements, then he is not afraid of diseases. But there are situations when the fungus begins to multiply actively:

  • if the room is kept at a low temperature at the level of 10-15 degrees
  • with excessive humidity, excessive watering and stagnant water in the container
  • when the substrate is oversaturated with nitrogen-containing fertilizers
  • when the plant is too crowded in the pot
  • if the flower is rarely watered, the earthen coma is brought to dryness, and then abundantly watered
  • any fungal infection spreads very quickly and can infect other plants located nearby:
  • when you touched a diseased bush, and then touched a healthy
  • if mealy fungal microorganisms got into the water intended for irrigation
  • with the movement of air masses - the fungus is able to move even through the air.

Often, plants at home encounter insect pests - their pathogenic activity also often leads to the appearance of spots and plaque on plants.


We create the right care

To get rid of white bloom, it is necessary to provide comprehensive care for the diseased plant. First you need to understand the cultivation technique:

  • Water the plant only when the topsoil begins to dry out
  • During the treatment of the plant, you can not spray it (except for medicinal purposes). This also applies to healthy plants in order to prevent
  • The flower needs to increase the sunny day, it is advisable to transfer the flower to a dry and warm place, with little direct sunlight
  • Withered and dry leaves and buds must be torn off
  • With this disease, you can not use any fertilizers and dressings.

Hide the plant from direct sunlight

Provide the plant with proper care, otherwise powdery mildew will become your regular visitor. Now let's move on to treating the disease.

Succulents Wax Plaque - What Is It?

Cosmic Succulents - 05/29/2019 01/12/2020

"Epiticular wax", "gray leaves" are completely unfamiliar terms not only among succulent lovers, but also plants in general. They refer to the "wax-like" bloom on the leaves of succulents, which you see so often and which surprises you, and some are surprised even so much that they thoroughly wash it, mistaking it for dust, which is absolutely contraindicated to do - this is a common mistake not only of novice succulent growers but also experienced growers in greenhouses or nurseries who are simply not informed. This plaque is a natural substance for succulents and is their natural sword and shield against many troubles.

Epiticular wax is a coating of wax-like substances (waxes) that covers the outer surface of the cuticle of a plant in terrestrial plants and plays a protective role. It can form a whitish film on leaves, fruits and other plant organs. You can also see the same wax, for example, on blueberries, plums, black grapes, nectarines.

Waxes - the class of lipids, esters of higher fatty acids and high molecular weight alcohols (usually monohydric) with an even number of carbon atoms. They also contain free acids, alcohols, often triglycerides and hydrocarbons.

  • Crystals of epiticular wax on a rose leaf.
  • Wax bloom on the leaves of different plants.

Why do succulents need plaque?

Plants produce epiticular wax that allows them to survive in extreme climates. For example, for succulents, wax helps to retain moisture reserves during a drought. It helps them grow safely in the burning direct sunlight and protects them from infestation from insects. For some plants, such as camellias, epiticular wax gives their leaves a glossy appearance and a strong sheen (some succulents also have this glossiness). In succulents, most often it manifests itself in a soft powdery bloom or "gray" (bot. Covered with a whitish bloom, gray-gray covered with efflorescence).

The role of epiticular plaque in succulents

  • Protects against moisture evaporation

On succulents, plaque turns the water into rolling beads rather than moisturizing the plant. Although it attracts dust and dirt, which sit tightly on it and it will be possible to remove it only together with the plaque itself, which is contraindicated, however, water beads can help you with this, rolling on a leaf, they take dust on themselves.

  • Protects from solar radiation

Plaque reflects ultraviolet radiation, essentially acting as a protective shield and preventing burns.

  • Makes the surface uncomfortable for insects to walk on or to lay eggs
  • Protects against mechanical damage.

Moreover, thanks to him, in bright light, succulents are painted in such bright and juicy colors as fruits! It is necessary to handle the plants as carefully as possible without erasing the plaque, because it does not recover and the spots left on the leaves make the succulents a little less aesthetically attractive. If you need to remove dirt from the leaves, just use a very soft brush to paint or simply blow it off.

Succulents are not only beautiful but also smart. Nature amazes with its care and forethought for each of its creatures, which it has created, from the smallest, almost invisible to the eye, to the largest. And only a rapprochement with her gives spiritual satisfaction, which no materialistic form or object in our life can give.


Gray rot

When this fungal disease appears on the leaves, stems and petioles, a fluffy coating of a gray shade appears, which eventually turns into rot. Gray rot can destroy a flower completely in a short time. It is very important to notice its first signs and immediately move the plant away from other specimens. If half of the plant or most of it is infected, then it will have to be destroyed, since there is no cure for this disease yet.

Fungal diseases appear where all conditions are created for them. It is very important to remember that when growing indoor plants, you must not violate the basic rules of care and maintenance. For example, you need to strictly observe the frequency and volume of watering, regularly ventilate the room. You cannot put flower pots with plants very close to each other, they need free air passage.

Plaque of black, red and other colors

In my almost 20 years of floriculture experience, I have seen different types of plaque. For example, red spots on hibiscus and pelargonium, which turned out to be a disease known as rust - mycosis caused by parasitic fungi. It looks like this: a bloom of orange, yellow or brown appears on the underside of the leaf, and soon the damaged part of the plant dries up.

  • The cause of the disease is dampness in the room at a low air temperature, from 10 to 20 ° C. The damaged leaves must be removed, and the plant must at least temporarily create a "hot climate". I temporarily closed my hibiscus with a transparent bag and put it in a warm place - near the heater.When the temperature under the hood reaches 30 degrees, the fungi will stop actively multiplying, but in order to cure the plant, you need to spray it with special fungicides several times (once a week for a month).

    It is impossible to spray with ordinary water at this time - spores ripen in droplets on the leaves.

    Another type of disease is black bloom on the leaves... It is caused by black sooty mushrooms, or rabble, as they are often called. They like to settle in the sticky traces of the vital activity of parasitic insects (thrips, aphids, worms). Most often citrus fruits, azaleas, camellias and palms suffer from black bloom.

    The leaf of a diseased plant looks like it is covered with black powder or a dark crust. This disfigures the plant, prevents it from breathing and inhibits the process of photosynthesis.

    Florists are advised to fight insects that leave a sweet bloom in which fungi settle, and you can improve the appearance of the plant by washing it well in the shower, carefully cleaning each leaf with a sponge. I have no plants that are susceptible to black bloom disease, and although any flower can get sick under favorable conditions for fungi, I am glad that I was lucky to avoid this trouble.
