Black spot

Black spot

Black spot is one of the diseases that affects plants. There are different causative agents of this disease. For example, Marssonina rosae is a fungus that infects roses. It is he who is the cause of the appearance of black spots on the foliage. Another pathogen is called Syringae. It can be observed when the lilac is defeated.

Features of black spot

It is very important to detect black spot damage to the plant in time. This will eliminate the disease in a shorter time and without side effects for the culture itself. Therefore, as a preventive measure, it is necessary to systematically conduct a careful examination of all parts of the plant.

In case of a disease with black spot, characteristic specks of brown, almost black color appear (therefore, the disease received this name). These spots may have a lighter center or edges. There are swollen specks that are either oval or round in shape.

The favorable time for the onset of the disease is the beginning of the summer period, so you need to make it a rule to carefully examine the plants at this particular time. The disease can develop at absolutely different rates. For example, with a rapid course of the disease, extensive foliar lesions are observed. It quickly turns yellow and falls off, and the branches become bare. The shrub is noticeably weakening, its decorative effect is lost, there is almost no flowering, and fruitful crops bring a very meager harvest.

An appropriate environment must be created for the infection to spread. High humidity, wind, and the presence of pests contribute to the rapid progression of the disease. This is especially noticeable during a long period of rains, when the air temperature is low. Potassium deficiency contributes to the spread of the fungus.

The beginning for the development of the disease can be a simple mechanical damage to either foliage or bark.

Black spot treatment

Before choosing a method for treating black spot, it is necessary to establish an accurate diagnosis, that is, to confirm the presence of this particular disease. There are two forms of the disease: caused by a fungus, as in the case of pink, and caused by bacteria, on tomatoes and peppers.

Unified methods have been created to combat black spot of any origin. The first thing to do is to take measures to strengthen the immunity of the diseased plant. This will stop the further development of the disease, and in the future, reverse it. There are preventive measures that improve the health of any culture.

Preventive actions

The first and foremost preventive measure for any crop is sowing seedlings in the right place. This requires a detailed study of the conditions that the plant requires for normal development. For example, shade-loving plants are planted in shaded areas. If there are none, you need to create artificial shading. And for sun-loving crops, open lighted areas are chosen. The reaction of the plant to drafts, winds, temperature changes is also taken into account. Failure to comply with these initial conditions weakens the culture. It becomes more susceptible to pests and diseases.

The second thing to consider is the quality of the soil. It must meet all the requirements of the plant. There are more whimsical cultures, there are less. Information on soil requirements can be easily found on the Internet. Don't be lazy. The soil is very, very important. The plant will develop normally only in the right, suitable soil for it.

On a note! Experts recommend choosing varieties with increased resistance to diseases and pests, as well as taking into account local climatic conditions. There are zoned varieties and hybrids, that is, intended for cultivation in a specific area. For example, for the Urals, Siberia, the Central strip.

Another preventive measure is the preparation of seeds before sowing. Seeds must be disinfected unless otherwise indicated on the packaging. The disembarkation is carried out within the specified time frame and according to the presented scheme.

It is important to properly care for the plants, including watering on time, and applying fertilizers to the soil. After harvesting, it is imperative to cleanse the site of vegetation remnants and put the soil in order.

Black spot on garden crops

As mentioned above, black spot can appear on different crops.

Black spot of tomatoes

Xanthomonas vesicatoria is a stick-shaped gram-negative bacterium that can infect both greenhouse tomatoes and those grown in garden beds. Seedlings and young bushes have watery spots on the foliage. At first, they look more like dots, and over time they increase to 1-2 mm. The edge turns yellow as it grows.

On adult shrubs, specks appear on the petioles, shoots, leaves, and also fruits. On the latter, dark spots have a watery edging. Over time, growing to 0.8 cm, they turn into sores. For a long time, the pathogen can be on plant debris, seed material. Before sowing, it is imperative to disinfect the seeds.

When parts of the plant located above the ground are damaged, the pathogen penetrates through cracks, damage. After that, it quickly spreads through the tissues. The first symptoms appear already on the 3rd - 5th day after infection.

On fruits, spotting appears a little later. And two weeks later, neighboring plantings are infected. The favorable temperature for the development of the disease is from 25 degrees and above. Deceleration occurs at lower temperatures.

Also, a favorable condition for the development of fungi or bacteria is increased humidity up to 70-75% with moisture ingress on the ground parts of the plant.

After harvesting the fruits, the site is carefully cleaned. This is necessary to eliminate the source from which the pathogen is powered. After 4-5 weeks, there will be no trace of fungi and bacteria. Breeders have not yet created varieties and hybrids of tomatoes that are resistant to black spot. However, gardeners have noticed that those tomatoes that have good immunity to the fungus are less likely to get sick with black spot. Therefore, it is necessary to carry out all preventive measures.

As already mentioned, preventive training is very important in the fight against infectious diseases. In particular, the correct processing of the seedbed. To do this, carry out the procedure for dressing tomato seeds. There are several ways to disinfect:

  1. Prepare a solution based on a fungicide and fill it with seeds. Duration of soaking is 1 hour.
  2. Treatment in a solution of potassium permanganate for half an hour.
  3. A solution is made from ternary sodium phosphate at the rate of 12 g per 100 ml of water. The seeds are kept in the finished solution for an hour, after which the planting material is thoroughly washed under running water. You can put the seeds in a sieve and rinse in this way for 20-30 minutes.
  4. Soak the seeds in hot water (about 60 degrees) for about 20 minutes.

These simple and reliable methods will help prevent blackleg infestation and remove bacteria and fungi from seeds, if present.

In case of internal seed infection, another method is used using the biological fungicide "Planriz" (1%). The treatment solution is prepared in accordance with the instructions and the seeds are immersed in it. Before planting in the soil, seedlings are treated twice with the following solutions to choose from:

  • Fitosporin-M;
  • Baktofit;
  • Gamair;
  • Planriz.

Fitolavin is especially effective.

Some time after planting tomatoes in the ground, it is imperative that a preventive spraying is carried out with a solution of a product that contains copper. For this purpose, Hom, Oxyhom, 1% Bordeaux mixture and other means that have a similar mechanism of action are perfect.

Black pepper spot

Sweet peppers and tomatoes have the same pathogen (Xanthomonas vesicatoria). It affects most often those parts of the bushes that are not yet sufficiently strong. It appears on petioles, foliage, fruits and shoots in the form of black specks. First, these spots are round, and then oblong. The original length is 1–2 mm. On closer inspection, you can see a border of a light yellow tint on the spots. They are located along all the veins on the leaves. In the center of the spots, necrosis is formed, which is surrounded by a watery dark border. As the lesion develops, the spots grow up to 6-8 mm in length. And from ordinary specks, they become rotting sores. Preventive measures are exactly the same as for tomatoes.

Black spot on fruit and berry crops

Fruit and berry crops can also get sick with black spot, including grapes.

Black spot on grapes

There are many alternative names for black spot of grapes: phomopsis, cracking of the bark, dry hands, ecoriosis, dying off of shoots. These are all names for the same ailment. The causative agent is the fungus Phomopsis viticola. The initial signs of the disease may appear in June on the nodes of annual shoots. The affected berries develop oval or round dark brown specks. They look bloated and watery. In the center of the spot is a necrotic focus.

Over time, their number is growing. The dots connect to each other, resulting in larger spots. An autopsy takes place in the center of such neoplasms. And the cork fabric around the edges looks like scabs. In most cases, only the first 6 or 7 internodes are infested with mottling. Also, spotting occurs on the leaves located in the lower part of plants, cluster ridges, antennae, flowers.

Leaf necrosis has a light edging. The leaves are curly due to the stretched fabrics. And in some places, gaps appear, which form holes. The foliage begins to turn yellow ahead of time, the leaves wilt and fall off.

Due to the deformation of the foliage and the formation of holes on it, the process of photosynthesis becomes weaker. It can also happen that many buds die in the lower internodes of the stems at the age of one year. Affected grapes become dark purple in color. There is a deterioration in taste, the bark acquires a grayish-white color.

Favorable factors for the spread of black spot are high humidity, wind, rain, pests. The diseased plant is less frost-resistant. As a rule, death occurs after 5 or 6 years. As with other crops, experts advise giving preference to those varieties that have good immunity. Such varieties include Cabernet Sauvignon, Liana, Traminer, Tavrida, Iskra, Riesling, Bastardo Magarachsky and Relay.

When the first signs of black spot are detected, it is necessary to immediately begin treatment of the grapes. A characteristic feature of this disease is the deep location of the fungal mycelium in plant tissues. For this reason, fungicidal treatments will not be highly effective.

It is recommended to use Nitrafen or DNOC for processing. These remedies eliminate fungal spores and fruiting bodies. Once again, it is worth recalling that timely processing is very important. And the best thing is to do prevention. This is the most reliable protection against black spot, which will save the gardener's time and energy and, of course, the harvest.

Black Spot (Escariosis) appears in early June

During the growing season, it is useful to treat as a preventive measure with the following means:

  • Mikal;
  • Efal;
  • 1% bordeaux liquid;
  • Eupren.

The first processing of grapes is carried out immediately after swelling of the buds at the very beginning of spring. The next spraying is carried out after the appearance of four to five full-fledged leaves on the stems. The third time is processed after the end of flowering. It is preferable to choose an agent with a complex focus, that is, one that will be effective against spotting, and peronosporosis, and powdery mildew.

When the culture is severely affected, spray with a solution with copper in the composition. Spraying time is after leaf fall or after pruning. The greatest effectiveness against black spot was shown by such fungicides as Triadimenol, Maxim, Kaptan, Mankotseb.

By choosing one of the above drugs, you can be sure of the effectiveness of the treatment.

Grapes require preventive spraying in order not to get sick with black spot. Below are the main preventive measures:

  • plant exceptionally healthy seeds;
  • regularly inspect plantings for signs of black spot;
  • when the first symptoms are detected, the affected parts are trimmed and burned;
  • the stems should not lie on the ground, so they are tied up;
  • make balanced correct feeding (boron and zinc are essential trace elements in the composition).

It is impossible to immediately eliminate black spot from grapes. Therefore, you should be patient and prepare in advance for a long struggle. After the final elimination of the disease, it is necessary to continue preventive treatments in the same mode, with the same regularity.

Black spot on flowers

Black spot on roses

Marssonina rosae - the causative agent of black spot on roses - affects both the stem and foliage. White-red spots appear on the outside of the leaf plate, which then turn black. They are round and look like they have a radiant border. First of all, the foliage is affected in the lower part, and then the infection spreads throughout the bush.

Affected leaves change from rich green to dark brown. Then twisting, drying and dying off occurs. The bush becomes weaker and weaker, decorativeness disappears. There are fewer buds or no buds are formed at all. With a high degree of damage, by the beginning of the autumn period, the foliage completely flies.

Black spot of roses We start the fight in September

When the first symptoms of a rose disease are detected, it is necessary to cut off the damaged leaf plates and remove the fallen leaves. They begin to spray the solution systematically at intervals of a week. To prepare it, you can take one of the following means:

  • Abig Peak;
  • Topaz;
  • Coming soon;
  • Thiophanate methyl;
  • Previkur;
  • Fundazol;
  • Trifloxystrobin;
  • bordeaux liquid.

The soil around the rose is spilled several times (preferably three times) with Fitosporin-M diluted in water.

In the fall, they begin to prepare the rose for wintering: they remove the foliage, collect those leaves that have flown around and wilted. It is preferable to burn it all.

The remaining bush is treated with 3% iron sulfate diluted with water. In the spring, before the growing season, all branches and stems are cut, down to healthy wood. Spraying of the bush itself and the soil around is carried out. The fungicides listed above are suitable.

Signs of black spot on a rose are similar to diseases such as brown and purple spot, phyllosticosis, sphacelloma, ascochitosis, septoria. It is very easy to confuse these diseases. However, there is no need to worry, because the drugs mentioned above are suitable for the treatment of all the listed diseases.

Preparations for black spot (fungicides)

Before you start treating black spot, you should carefully read the instructions for the fungicide, its action, what it is used for, in what quantities.

How to treat roses for black spot

Folk remedies

Despite the presence of a large number of a wide variety of fungicides, folk remedies do not stand aside. Of course, they are not so effective in terms of therapy when the plant is already sick. But they are well suited as a preventive measure. Below are some recipes.

  1. To prepare the solution, you only need iodine and water. Take 1 mg of iodine and dissolve in 2 tbsp. l. water. Spraying is carried out.
  2. This recipe is for processing roses. Mix the mullein with water in a ratio of 1:10. The resulting mixture is insisted for several days in a row. At the onset of spring, after removing the shelter from the rose, pour over it with the resulting infusion. Several more procedures (two or three) are carried out from May to July.
  3. Take garlic or onion peels in the amount of 30-40 grams, boil. Next, the broth is infused for 6-8 hours, after which it is filtered. The resulting product is used for spraying rose bushes, as well as for cultivating the soil under them. When there are flowers on the bush, they no longer spray it, but pour the broth right at the root. Spraying can lead to a change in the color of the petals.

There are a large number of gardeners' reviews where they do not recommend using citrus and herbal infusions (for example, from nettle), because they are ineffective against black spot.

So, black spot is a plant disease that is caused by various kinds of pathogens. It can be either bacteria or fungi. Black spot can often be observed on roses, tomatoes, and peppers. The disease also appears on berry, fruit, vegetable, melon crops. Favorable conditions for the development of the disease are high humidity, low temperatures.

A characteristic sign of black spot is the appearance of spots on the plantings. It is necessary to carry out preventive examinations of plants and, when the first symptoms are detected, immediately begin treatment. There are many fungicides that can be used to combat black spot. There are also non-traditional folk methods for processing plants. They are suitable as preventive measures.

This disease destroys the leaves of the seedlings. This disease is manifested by specks of light colors with dark gray dots and darkening, then they spread throughout the plant. The leaves turn brown, dry out and fall off. The infection spreads through diseased soil. It is recommended to get rid of diseased plants.


Black spot

Norway maple can also suffer from black spot. How she looks like? Dark uneven spots on the leaves are its manifestation. As a preventive measure, use spraying with a 2% solution of foundationol or copper sulfate and 300 g of grated laundry soap per 10 liters of water. This is done in early spring. And if the disease has already begun, then spraying with onion peel infusion helps.

Black spot indicates a good ecology of the area. In addition to reducing decorativeness, there is no harm from this disease. It is very important to create optimal conditions for the growth and development of maple, increasing plant resistance to diseases. Branches affected by diseases must be cut and destroyed. The same is done with the fallen leaves of the affected tree. Preventive spring spraying with fungicides can be carried out.

Frequent problems in plant care

Excessive watering can lead to fungal root rot diseases. Because the crop is drought tolerant, it copes better with little water than too much water. Extreme cold weather can cause the grass to die off. It will die in winter if there is a prolonged period of frost below -23 ° C.

Pests

Your plants won't experience many pest problems. In rare cases, aphids can penetrate tall leaves, but they can be controlled. How to get rid of the pest can be found in our article.

Diseases

Two illnesses can occur, but the only serious one is black spot or Villahore. This fungal disease can damage or kill your plants. To keep it out of your garden, make sure your plants are positioned to provide adequate airflow.

Another disease that does happen, albeit rarely, is rust. Common rust looks like a speck on leafy leaves. A common cause is too much moisture or poor airflow. Thin your plants from time to time.


Leaf spots - protective measures

As you can see, the spots on the leaves are different, and the measures to combat them are always different. Against spots on plants, it is customary to carry out preventive and eradicating treatments with copper-containing preparations: in spring, at the beginning of summer and with a strong spread in autumn, especially on roses.

The caterpillars of moths feed inside the leaf blade, and it is impossible to get them there. The most effective is the collection and burning of leaves with pupae in early spring and prophylactic spraying of plants with phosphorus-containing preparations in May or early June, during the emergence of butterflies and oviposition.
