Violet leaf spots
Content:
The most famous consequence of the formation of spots on violets is improper care: irregular, irregular watering of the plant, excess or lack of moisture in the soil. It is necessary to adjust the humidity in the room where the violets are grown; diagnose the composition of the soil. Perhaps there was an excess or lack of essential nutrients, and because of this, spots appeared on the leaves of the violet. Or the plant is incorrectly positioned - constant direct rays of the sun or drafts.
Only after checking all the above points, correcting as necessary, can we hope for the plant to recover and its further prosperity.
If you have eliminated all the shortcomings in care, and the violet is still stained, then the reason is the defeat of fungal or infectious diseases, as well as parasitic pests.
This problem, at more common stages, is practically not solved, only the elimination of the plant will help. But to exclude such a situation, try to adhere to the schedule of preventive maintenance.
Reasons why spots are formed on violet leaves
When you made the decision to grow violets, then you know exactly what you want. Violet is a capricious plant, and most importantly, it is completely devoid of natural immunity to various diseases, parasite lesions and reacts negatively to all the minuses in care. It is necessary to take this into account and take care of the pets. Especially so gentle and defenseless.
Important! It is very easy to break the rules of care, but to eliminate the consequences is very difficult and sometimes even impossible task. Since most diseases are not treated, and the plant affected by the disease must be urgently destroyed.
The most common causes of stains on violet leaves are:
- violation of the system and rules of plant care;
- the onset and progression of diseases;
- the appearance of parasitic pests.
Stains appeared on the leaves of violets - the rules of care were violated
The appearance of spots on the plant is, initially, improper care of the violet. Below we list the most popular points (mistakes) of violation of care:
- lighting is disturbed: either not enough, or an overabundance, direct sunlight also causes irreparable harm to the flower;
- the plant, of course, needs a transplant, but this must be done only at a certain time and subject to all the rules. Violation of the system leads to a weakening of the plant and the formation of spotting;
- untimely, irregular, improper watering of the violet has a detrimental effect on the full well-being of the flower, respectively, the formation of violations on the surface of the leaves will follow;
- the presence of constant drafts leads to a violation of the temperature regime, this is also the reason for the appearance of spots.
Constant unsettled care will lead the plant to death. Even with the slightest signs of the manifestation of diseases, it is necessary to take urgent measures, but first of all, it is necessary to identify the cause of such a problem.
Why did spots appear on violet leaves - lighting is disturbed
The delicate plant has a negative attitude towards direct sunlight. Being constantly in the bright sun, the leaves receive a fairly severe burn, specks of a rounded shape, yellow in color, appear rapidly. Over time, the spots turn brown. The appearance of small holes in the center of the sheet plates is observed.
How to determine if the spots are a consequence of the burn? Spotting appears mainly on the side of the windows. All pots of violets must be moved to a place that is well lit, but out of direct sunlight. Leaves affected by burns - remove. Inflorescences are also capable of getting burned, therefore, damaged flowers are also removed. The most optimal solution to the problem would be to place flowers on the northwest or northeast side.
Transplant was made unnecessarily or out of time
When the inner side of the leaf is affected by the spot, the spots are predominantly brown in color, then we can say with confidence that a transplant is necessary.
Brown and brown spots on violet leaves
There is one more indication, with the manifestation of brown or brown spot. This is the alkaline state of the soil, it cannot be changed, so only a transplant is needed. It must be carried out according to the following rules:
- Remove the flower very carefully from the pot, just carefully, be sure to check the moisture content of the soil, it is not recommended to transplant when dry. All events should be carried out neatly. The root system is very vulnerable, try not to cause even microscopic damage, which can later cause rot diseases;
- Old soil with a root is gently shaken off;
- Cut off all affected leaves with sharp instruments, which must be treated, for example, with alcohol. Treat each cut point with charcoal powder.
- Plant the bush in a new pot and renewed, prepared soil. Keep in mind that the plant will increase in size as it grows, so pick up the pot 2 sizes larger than the previous one.
- Soil for violets is sold in any specialty store, but drainage must be created with your own hands, for which it is recommended to use sphagnum (moss). Make sure that there is no phosphorus in the purchased composition of the soil mixture, since this element provokes a very rapid aging of the plant.
Violation of proper watering, as a result - spots on violet leaves
Watering is a very important process when growing violets. It provides a number of rules to be followed when growing violets:
- when watering with water at a low temperature, the plant instantly reacts negatively, specks of light tones appear on the leaves. When a direct sunlight hits a plant, or rather wet leaves, a leaf plate is burned, and brown spots are formed.
- watering is necessary only with water at room temperature. The process itself is carried out as recommended, in the evening. At such a moment, your plant will not be able to get burned if it is located on the windowsill on the sunny side.
Are there stains on violet leaves? Drafts are one of the possible causes
The delicate violet plant is categorically afraid of any draft. Even warm, sunny summer weather shouldn't force you to create drafts in the room. Or move the plant a sufficient distance from open windows. Leaves, which are caught by a draft, begin to become covered with spots of white and brown. The form of heel formation is different, it all depends on the degree of damage.
As a solution to the problem, simply locate the violets in a permanent place where the draft will not threaten it. The plant is able to independently grow new foliage, restore strength, although this will take time.
Diseases and pests
The appearance of spots on the plant, a change in the color of the leaf plates - these can be not only the consequences of improper care. It's just that the violet was struck by the disease. What kind of diseases can harm a plant, we will consider below:
- powdery mildew;
- various rot;
- fusarium;
- late blight.
- virus of bronzing and stains on the plant.
Causes of the appearance of diseases
The disease can be caused by various reasons. This may be the wrong approach to care, the growing process itself, even a small non-observance of the conditions will serve as a disease of the violet, since this flower is a very delicate plant, the natural ability to self-defense is completely absent.
The most common causes of sores are listed below:
- you initially selected the wrong soil. The largest percentage of infestation of violets occurs when grown in forest soil or soil from a site. It is recommended to purchase a special soil composition, this is sold in any flower shop;
- the formation of a fungal disease can lead to a lack of the following nutrients: phosphorus, potassium, various minerals;
- also the fungus reacts positively and begins active development in the soil where the nitrogen content is exceeded;
- the appearance and activation of diseases is caused by improper care of the plant, literally provoking the appearance of a sore. High humidity will have a categorically negative effect on development, especially on flowering. Temperature changes lead to diseases, making the plant very weak, unable to cope with the disease on its own. Poor lighting or too much direct sunlight.
Types of diseases
Powdery mildew - when affected by such a disease, the leaf plates are coated with a bloom of gray or white. This can be easily wiped off with your fingers or a cloth. This is certainly not a solution to the problem. Plaque leaves look and feel very weakened. The fungus, if urgent measures are not taken, can rapidly spread to the buds and neighboring plants, which later will also be affected by the disease and the infection will already take on a large scale.
Leaves infected with a fungus begin to turn brown and gradually die off, crumble. A bud affected by a fungus stops in development, does not bloom, a little later it will simply disappear. Fungal diseases are very difficult to treat and it is not a fact that the violet can be saved.
As a recommendation! Systematically carry out preventive work with your plantings.
But if this happened and your flowers still get sick, then you must follow the following instructions:
- be sure to cut and destroy all damaged leaves. The instrument must be sterile at the time of cutting and after work it must also be treated with a special agent;
- urgently isolate the violet bush from other healthy plants, this must be done for the safety of neighboring plantings;
- with minimal damage, all leaves, sick and healthy, can be processed simply by rinsing with a solution of ordinary manganese. With a very weak solution, it will be enough to dilute one liter of water and 1/4 g of potassium permanganate. Repeat this procedure again after about 5-7 days to exclude a relapse.
- When the scale of the lesion is of great importance, the following, already the most powerful drugs, are used: Topaz, Zircon, Skor, Epin, Copper sulfate.
Rot Infecting Violet
Rot is one of the many diseases that affect violets. This is an equally dangerous infection that can harm the health of flowers. The following circumstances can cause the appearance of rot of the root system and leaf blades:
- the plant is incorrectly divided;
- it is possible that the tops of the rosette were trimmed at the time of transplantation and the rules for pruning and transplanting were violated, or the tools were not processed, or microscopic injuries were caused to the violet;
- it is possible that the children were separated by breaking the rules;
- there is a variant of damage by pests carrying similar diseases;
- violated the rules of watering, the amount of water for a one-time application.
How to identify the disease at the first sign for emergency care?
Listed below the main signs of disease:
- the appearance of brownish specks that grow as the sore spreads quickly throughout the plant.
- leaves and buds become lethargic, elasticity is lost;
- further on, the leaves and stalks of the violet wilt;
Treatment should be started immediately, regardless of the extent of the lesion. If the damage is significant, then it is necessary to completely remove all damaged areas. If this does not help, then the bush is completely destroyed. And a new bush can be obtained by rooting healthy leaves, with a successful process, it develops further and a new outlet is obtained.
Brown rot - such a disease affects all parts of the violet - young rosettes, all available children, rooted leaves, petioles. There is a color of the stems, those that have taken root, in brown and brown tones, gradually they become weaker, thinner. At the rosettes at the soil level, a thin filament of mycelium of a whitish color appears.
When a disease is detected, urgent measures are taken to combat the disease. Rot, like a fungus, rapidly spreads not only along the infected bush, it follows further, affecting all neighboring plants in the room, and not only the neighboring ones.
For each rooted plant, periodically carry out preventive work to prevent the appearance of the disease: use known fungicides for this, only for the ground part of the plant. Spill all parts underground with phytosporin.
Root rot - initially, the disease begins to appear on the surface of the leaf plates - they are covered with a spot of a pale shade, then an inevitable wilting occurs. When the affected plant is removed from the soil, you can observe the softened mass of the root system.
The cause of the appearance of a sore is high humidity or low acidity of the soil. To combat the disease, simply reduce the quality and quantity of irrigations.
As with any disease, it is recommended to systematically carry out preventive work, preferably by root treatment. Fitosporin is used in this case. If you choose a moisture-retaining soil composition when planting, then you can avoid the appearance of such a disease.
Gray rot - with this kind of disease, a plaque appears, fluffy to the touch and gray in color, spreading occurs preferably on leaf plates. A very serious illness and no less dangerous. The plant weakens very quickly and the green parts of the plant begin to liquefy.
There is practically no treatment, you can reduce the risk of damage to even healthier leaves by cutting off dead ones, only very carefully, since rot can get into the soil, where it will calmly wait for time for further activation on young, rescued shoots.
To reduce the risk of infection, take the following measures:
- observe the mode of humidification of the plant and the room separately;
- moistening should be carried out only by watering under the roots, in no case spray the leaves;
- watering is carried out correctly, without disturbing the regularity. Stagnant moisture and condensation formed will lead to the manifestation of the disease.
- do not spray violet leaves.
Spots on violet leaves - signs of fusarium and late blight
Originally fusarium affects the root system of the violet.Mass decay begins. Having mastered the roots, the disease begins to actively spread to other parts, moving along the vascular system of the plant, then to the stems and the lower sides of the leaf plates. The leaves are covered with brown spots, the edges of the leaves become watery. Over time, the violet fades and a complete dying off occurs.
What are the reasons for the spread of the disease? See below:
- the temperature in the room drops sharply, the maximum degree is +16;
- after flowering, the violet is the most weakened. At this moment, any little thing can provoke a disease;
- exceeded doses of fertilizers or their lack lead to the appearance of such diseases;
Having discovered the appearance of fusarium on your violets, urgently isolate the plant from neighboring flowers. The bush itself is destroyed completely, along with a lump of earth. It is advisable not to reuse the pot, in extreme cases, after some time and with good treatment, for example, with fungicides.
Unfortunately, the plant itself cannot be saved, since there is no cure for such a disease.
Regularly, systematically treat violet bushes with phytosporin to prevent disease.
Late blight - The signs of this disease can be considered the appearance of brown, dry spots on the leaf cover of the plant. It spreads very quickly, rapidly, the tissue of the plant is damaged by necrosis in a short time, the rosette of the flower withers.
At the moment when the disease is detected, but the tops of the sockets are not touched, they can simply be removed, cut off. The cut site is treated with fungicides, the damaged areas must be cut off at the root.
The plant can be rooted, while using young shoots, individual leaves. The remaining parts are subject to immediate destruction. Treat all neighboring plants with a special prophylactic agent.
Leaf viruses
Viruses cause significant damage to the plant, have the ability to inhibit the development of violets, the appearance of the leaf plates changes dramatically, and flowering stops.
A number of reasons can be emphasized that provoke the appearance of the disease, for example, pest parasites have settled in the bushes. The bronzing virus manifests itself in the form of a change in the appearance of the leaves - disfigurement occurs, color in brown tones.
It is almost impossible to cure the virus, the plant is completely destroyed, along with the soil.
Parasites
The diseases themselves are very dangerous, but some of them are manifested due to the appearance of parasites on the flowers. This phenomenon is even more dangerous than illness. The main danger from the parasite is the spread of the disease, which, in turn, causes irreparable harm. Violet bushes die.
Let's highlight the most popular and dangerous insects for violets:
- Cyclomen mite - it is possible to detect the parasite only after the development of young leaves. When infected with a tick, the violet will completely stop developing, flowering stops. The leaves curl in the center of the rosettes. Brown spots appear. When fighting, use Fitoverm or insecticides.
- Nematode - insects live directly in the vascular system and violet roots. The insect feeds by sucking out the juice, during this process the plant is poisoned with toxins. It is they who destroy the process of tissue nutrition. The development and flowering of violets stops. When infected, the shape of the plant changes, the size, that is, the plant becomes smaller, a large number of additional children appear, and nodes are formed on the root system. There is no cure for this disease, so the violet bush is completely destroyed, the pot must be disinfected.
- Aphid - this pest makes itself felt at an early stage, so it will not be difficult to detect it.The sticky content of the discharge begins to cover the back of the leaves, petioles and the main bush. To wash off plaque, you can use a solution of ordinary soap. For a more radical solution, Fitoverm is used, you can use the drug Antitlin. From folk remedies, tobacco dust is applicable.
- Thrips Is almost the most dangerous parasite pest. Reproduction is accelerated, it also quickly spreads to neighboring plants. They are carriers of many diseases of the violet. In this case, treatments with Aktara are recommended. It is necessary to process the entire flower-bearing plant, the bush completely, even the root system along with a lump of soil.
- Mealy bug - manifests itself in the formation of white flakes, directly on the leaf plates and petioles. On the surface of the soil, you can see lumps of a whitish hue, this is the lair of the parasite. The consequences of damage by a worm: yellowing of the leaves, their rapid wilting occurs. To get rid of the pest and restore the violet, it is recommended to apply - Regent or Mospilan. All parts affected by the worm must be cut off and destroyed immediately.
- Sciarids - outwardly, these are just small black flies. Such a parasite feeds on violet juice. And the larva of the pest can harm the root system of the plant. To combat, insecticide preparations are used. The most important thing is quality care for violets.
Conclusion
So, in our article we examined many reasons for the formation of spotting on violets. But only one conclusion can be drawn, and the most important one is the correct approach to planting, high-quality, regular care during the entire activity of the flower. That is, a simple attention deficit will cause flower disease.
Since, without proper care, various destructive sores and no less dangerous parasites - pests begin to manifest themselves. A well-established care system will bring a beautiful, healthy state of violets, flowering will become long-lasting, abundant, will always delight your eyes. And all the dangers to the plant simply do not threaten.
Important! The primary action in the event of a disease, if it did happen, is to immediately isolate the diseased bush. Regardless of the degree of damage. If the top of the plant has not yet been touched, then it can be rooted, and all other parts are immediately treated with appropriate means.
In the event that it becomes clear that the plant cannot be saved, then the bush and the entire earthen lump are urgently destroyed, and the pot is treated with a disinfectant.
In general, the health and beauty of violets is only in your hands.
