Rusty spots on roses than sprinkle. How to deal with rust hitting roses

The most dangerous and intractable diseases of roses are fungal: rust, black spot and powdery mildew. Fungal rose diseases and their treatment  they are distinguished by the fact that they are fairly easily diagnosed, but are very poorly treated. Therefore, the best way to avoid the appearance of fungal diseases of roses is to carry out preventive measures.

Rose Disease - Rust

This disease is considered one of the most dangerous. The harmful fungi of this plant are spread by insects or wind. If a   on the leaves of the rose is aphid or even some pests, then the fungi spores rust settle on the secretions of these insects.

A sign of infection of the plant with rust is the appearance of rust spots on the leaves in the spring. Later on, bright orange growths appear on the underside of the leaves, inside of which there are spores of the fungus.

Closer to fall, the growths turn black, and leaves that are affected by rust fall off. The fungal rust of roses also affects young shoots, which bend and redden.

Rose Disease - Black Spot

Signs of this fungal disease on roses can be found in the second half of summer. Black or brown radiant spots appear on the upper surface of the leaves. Infected rose leaves gradually turn yellow and fall off. Fungal spores of plants infected with black spot are easily carried by the wind.

For the prevention and treatment of black spot roses are largely suitable methods used to combat the rust of roses. It should be added that fungicides, which are processed in advance by healthy roses, are used as a prophylactic agent to combat black spot. These drugs, getting inside the plant, in the early stages of the disease cause a therapeutic effect.

Mealy Dew on Roses

Roses are sick quite often with this fungal disease. Usually, the disease affects plants grown in greenhouses or at home. Signs of powdery mildew are white bloom on stems, leaves, young shoots.

Outwardly, a white plaque consisting of spores looks like flour. When the spores mature, liquid drops form. From here came the beautiful name - powdery mildew.

The spores of this fungal disease spread very quickly, affecting the entire bush and neighboring plants. The leaves of the affected plants are curled, the flowers and stems are deformed. If the plant is not treated, it may die.

Good results in the treatment of powdery mildew on roses showed a copper-soap solution, which is prepared by dissolving 100 grams of rubbed soap with 10 grams of copper sulfate in 10 liters of water. With this preparation, the affected plants are treated every tenth until the white bloom has completely disappeared.

Diseases of roses and treatment of them bring a lot of trouble when growing these beautiful flowers, but care will be easier if you carry out prevention of diseases and strictly adhere to agricultural techniques.

Rose rust is an incredibly contagious attack that spreads at lightning speed and greatly weakens luxurious rose bushes. The roses attacked by her stop blooming and shed most of the leaves. It will not be difficult to bring rust into the garden, but it will be extremely difficult to get rid of it. Often it is this unfortunate ailment that causes the rapid death of roses. It is much easier to prevent it from occurring than to try to get rid of it.

A few words about the disease

  It will not be difficult to recognize rust on roses: piles of bright orange-yellow tones begin to appear on the wood. Similar heaps of spores, only slightly smaller, appear on the leaflets on the lower sides. And on the upper parts of the leaves gradually appear yellowish-reddish specks, after some time covering the entire leaflets.

Infected areas of the bark crack, shoots thicken, bend and subsequently shrink.

The causative agent of rose rust is the pathogenic fungus Phragmidium subcorticium. Especially dangerous is rust for remontant roses and centifolia, as well as for a number of wild roses. To a large extent, its development is facilitated by plant-growing, sultry weather, accompanied by a prolonged drought. In principle, rainy summer also contributes to the development of rust.

How to fight

Infected leaves of roses should be systematically collected and burned, and the shoots attacked by rust should be cut off just below the affected areas. Too much affected pink bushes, as if they were not sorry, should be dug out and quickly burned, after having poured over kerosene.

It is advisable to avoid as much as possible mono-planting of roses, planting to them pretty and helpful neighbors - yarrow, wormwood, monard, marigolds, and even garlic. All these representatives of the green world are famous for their disinfectants and immuno-strengthening properties. Also, when planting roses, excessive thickening should be avoided.

When watering roses, it is important to ensure that water does not fall on the leaves. For spraying with stimulating and herbal solutions and infusions, this recommendation does not apply.

Growing roses are recommended to be periodically fed, and the dressings can be both root and foliar. Perfect for this purpose nettle infusion. To prepare it, the plastic bucket must be driven to the very top of the freshly collected nettle. And so that the resulting infusion does not have to be filtered later, you can put the nettle into unnecessary old nylon tights. After that, nettle is poured with cold water and allowed to brew for ten days or more (as a rule, until fermentation is over). From time to time the composition should be mixed, but the lid should not be closed. By the way, if you put the infusion in a warm place, there it will ferment much faster. For root dressings, the finished infusion is diluted 1:10, and for foliar, 1:20.

As soon as the first signs of rust are noticed, it is recommended to treat the roses either with Bordeaux mixture or with other preparations containing copper. It can be such means as "Ordan", "Hom", "Oxy" or "Abig-peak". Well proven in the fight against rust and drugs such as "Strobe" and "Topaz". At the same time, it is best to take sprayers with fine-dispersion injection. The smaller the droplets of the solution during treatments, the stickier and thinner the leaf cover will be. And in this case the preparations will be consumed in much smaller amounts, which is extremely important when using sulfur and copper containing fungicides - much less heavy salts will get into the soil.

A good folk remedy against rust of roses is an extract of wormwood: 400 g of fresh grass should be placed in a wooden bowl, pour ten liters of cold water and leave for two weeks. Next, the composition is filtered and diluted with water in a ratio of 1:10. In order not to dilute the infusion, you can insist on it for one to three days. This tool is also very good at dealing with caterpillars and aphids.

With the onset of autumn, before covering the roses, all foliage should be removed, and the roses should be treated with Bordeaux mixture or three percent copper sulphate.

Rust on roses - one of the very serious and common diseases of roses, which involves qualified treatment. The cause of this disease are mushrooms of the genus Phragmidium disciflorum. The fungus infects other flowers and appears at the end of spring, when you can see spores on sunny rose bushes. The first spores of fungi appear on the stems, not on the leaves or buds. Infected parts of the stems crack and gradually the plant completely dies. A clear sign of the disease is a bright debate on bushes, leaves and flowers. Favorable conditions for the development of rust is an excess of nitrogen and moisture, for example, if the rainy period is delayed. This disease spreads easily through the flower garden and even the garden, and it is very hard to grow these mushrooms. Sometimes in a short time, the bushes become victims, and sometimes whole flower beds.

How to deal with rust

At the first signs of illness, you need to start a whole program to heal your precious flowers. First you need to establish the disease, its cause, find out the sources and extent of the disaster. The rust is visible immediately, it appears in the form of ugly brown spots, or if you started the situation badly, black spots appear. Some biologists insist that these are two different types of rust - black spot and brown. In any case, you should regularly review your plants and do not overdo it with watering.

In order to cope with this situation, you need to cut everything that is slightly affected by a fungal disease, and burn it. Even if there is a very small spot on the stem, you still need to destroy everything that causes suspicion in order to prevent further epidemics.

Then healthy bushes need to be processed. There is a folk remedy - a solution of household or baby soap. It represents the greatest effectiveness against aphids, but in this case it is also quite an acceptable option. To prepare, you must purchase a soap with sufficient alkali content. Two pieces of soap need to be dissolved in a bucket of hot water, cool and process the remaining bushes. A similar procedure should be carried out for several weeks in a row, with regularity in a day or two. Then, one solution should be exchanged for a decoction of nettle or horsetail.

Also, the infusion of wormwood has proven itself well. To prepare it, they take four hundred grams of fresh grass and pour ten liters of cold water. It is very desirable to keep the infusion in a wooden rather than iron dish. It is necessary to insist at least one day - then you can water it directly with this solution, or up to two weeks, then the resulting liquid must be diluted with water. Sometimes use ground sulfur or a mixture of sulfur with slaked lime. It is important to remember that sometimes water, such as rainwater, washes away the prepared solutions and reduces the effectiveness of any drug. In this case, having sustained a minimum pause, you need to repeat spraying.

There are specially designed pesticides for rust control: Bacillus subtilis, Kresoxim-methyl, Penconazole, Propiconazole, Fitosporin-M, P. These are the latest developments to cope with it. After the treatment of the contamination area with chemicals, specialists have developed a timeline for people to go to the land treated with pesticides to carry out manual works for the care of flowers. They are calculated by a certain number of days for each specific case.

In addition, the equipment you use also needs to be thoroughly disinfected after work, if you know that there is a problem in the garden or in the flower garden to avoid reinfection. It is also important to handle inventory if you have planted a new purchased shrub or flower. And very carefully watch this stranger from the nursery, on the subject of health. Very often, the incubation period of the disease lies behind the external well-being. These security measures are necessary, no matter how to miss a threat or during the time to eliminate the source of danger.

But even if, you coped with fungal diseases. We also need reinsurance measures - carefully trim a bush that had healed the roses before winter. Leaving the shoots at the level of the third bud from the ground. Also, replace the top layer of the ground where the fungus could remain, and make fresh mulch.

It is necessary to carry out the prevention of roses before the appearance of flowers in the form of foliar feeding with a solution of superphosphate and thorough wetting of the leaves with the same solution. Correctly select the dosage, so that instead of the benefits not to harm the plant. Small local lesions on the bushes can be sprayed with Bordeaux mixture, Skorom, Topsin-M.

For prophylaxis, fungicides are often used, and decoctions of nettle, horsetail, or soap solution, use them to prevent the development of fungal diseases and against aphids.

So, rust can lead to serious problems.

If you systematize the above, then to combat it is necessary:

  1. Regularly inspect the bushes.
  2. Take preventive measures before the blooming season.
  3. If fungal lesions are found, it is necessary to treat with folk methods.
  4. If it does not help - chemical compounds.
  5. Shrubs, where spots are found, carefully cut.
  6. Affected leaves and diseased shoots, burned.
  7. In the fall, pruned roses are pruned as a preventive measure.
  8. The top layer of the earth is replaced.

As we see nothing supernatural does not need to be done in order to cope with the disease. But you need to treat fungal lesions with all seriousness, so that they do not spread over the flower garden. Such ugly spots can appear on other flowers and plants.

Why are flowers sick?

Roses, as well as other flowers, require some care and care. In order for them to grow, bloom and delight our vision, and the sense of smell, you must follow certain rules for the care of this particular flower, a particular variety.


In order not to deal with the consequences of diseases, preventive measures are needed, and be sure to take into account the needs of each flower, plant or shrub. How much the plant loves and needs in sunlight, moisture, fertilizers, which soil is more suitable, which will not work at all. Very often, problems begin when the rules for the care of a particular flower are not followed.

How to care for roses:

  1. Provide enough light
  2. The ground should be light, you can, sandy-clay, which will not trap moisture.
  3. Weed and loosen the ground.
  4. Watering is necessary - moderately.

Some flower growers, by choosing easier varieties resistant to rust and some other diseases.

Interesting to know:

  • The rose is a flower that has been grown for aesthetic pleasure since antiquity, not for food or drinks. Artists admired it, sang poets, wrote prose writers about a rose. Images of roses were found on the palace columns of the 3rd millennium BC. er in ancient Babylon. Even a war called the war of white and scarlet roses entered the story. Verses are written about it and songs are sung. The rose remains a symbol of love and loyalty in many countries.
  • Some types of roses have been introduced by man - some by nature. Rosehip, which grew in the wild for centuries, became the ancestor of artificially bred several tens of thousands of varieties of roses.

Rust on roses is the most common disease among these demanding and exquisite beauties. This fungal disease is detected quite easily and quickly by the characteristic spots of lesions. However, the fight against this disease for gardeners becomes a true ordeal. Therefore, it is easier for a caring owner to prevent the spread of this disease than it is painful to get rid of dangerous pests.


Rust or spotting?

So, how to recognize rust, if it appeared; how to fight it; and what preventive measures to prevent it must be taken. Rust is considered one of the most intractable diseases caused by the fungi of the genus Puccinia. Most often, these fungi are carried by wind through the air or by insects. Usually there are two similar types - black spot and rust itself.

In the first case, the initial symptoms of the disease appear somewhere in the middle of summer. Thus, the spores of fungi, transferred by the wind, affect the upper side of the leaves, which are covered with black-brown spots. Then these once green and glossy leaves start to turn yellow and fly around. Next to replace the old foliage, young shoots grow around August-September. But it is difficult for weak sprouts to survive the autumn frosts, and then the winter, so the capricious and whimsical plant dies.

In the case of rust, the symptoms are somewhat different. This disease is always accompanied by infection of roses with other pests - aphids and worms. Rust appears at the beginning of spring in the form of characteristic fungal pads with spores.

It is they who darken over time and turn into black specks on the leaves. In this way, the difference between rust and black spot in terms of detection. In addition, rust begins to appear on the stems, gradually hitting the inside of the leaf, and black spotting can be found only on the surface of the leaves.

Treatment and Prevention

For the treatment of diseased shoots and leaves of rust used fungicides, as well as natural decoctions and infusions of soap, nettle or horsetail. These funds are specifically designed to combat and prevent disease. But before that, it is necessary to remove all the affected shoots collected from the diseased bush. All collected material that was found on and under the bush is immediately burned. In no case can diseased leaves and shoots be used for composting.

Even the top layer of soil is better to replace with a new one in order to avoid re-infection. Shrubs, rust, well pruned for the winter. In the spring, before the appearance of the first foliage, the rose bushes cut in the autumn should be well sprayed with fungicides. These measures will have a therapeutic effect and prevent the growth of fungi.

In the future, in order to avoid the recurrence of rust and other diseases, it is necessary to carry out regular prophylaxis, otherwise diseases will seize all plantings. To do this, it is important to carefully choose the place of landing of roses. Factors such as properly selected soil, light exposure, protection from the wind, play an important and sometimes key role in protecting plants from pests and various ailments.

If your roses are noticeable rust marks  - it means that it is too late to fight it. This fungal disease is very difficult to cure, you somehow have to take drastic measures and be uncompromising - because the longer you delay the treatment of your hives, the more irreversible will be the weakening effect on them of the fungi that cause this disease.

First step in rust fight  should be timely diagnosis. The sooner you identify a lesion, the less damage will be done to your roses. Since rust has no hidden incubation period and immediately appears on the stems and young leaves as rust spots and bright orange pads on the inner side of the leaves (real rust) or in the middle of the season black spots on the outer surface of the green sheets (black spot) are very easy to detect. Regular inspection will allow you to notice the first symptoms of the disease and react in a timely manner.

Affected leaves burn (even if only one spot is visible on them!), and if there are spots on the trunk, cut it as low as possible. Next, spray the bush with prophylactic mixtures to prevent the spread of the disease. After removing all the damaged parts of the plant, spray the bush with soapy water. The quickest way is to dissolve a bottle of liquid soap in a bucket of water, but this method is effective in combating aphids, while toilet or laundry soap (buy a simple domestic baby soap or a bar of high alkali in a pharmacy) fights rust much better. Two bars of soap need to be dissolved in a bucket of hot water, cool - and the mixture for spraying is ready. She sprayed rose bushes, trying to go through and the lower side of the leaves twice a week until the threat of rust has disappeared. Protecting your roses from rust should always be focused on prevention, because curing plants from this difficult fungal disease is almost impossible. Next, the soap solution should be replaced with a decoction of nettle or horsetail or specialized means for roses - Sistan. If in the summer you find black spot, then you should resort to more serious measures - spraying fungicides.

Inventory should be thoroughly rinsed after each use when spraying, and most use disposable gloves. If you use cloth gloves, be sure to wash and boil them after each treatment of the bush with soapy water and prophylactic agents.

Even if you get rid of rust and no longer find its traces on the leaves, in the autumn the affected bush should be subjected, leaving the shoots at the level of the third bud from the ground surface. Try to replace the entire top layer of soil in which the fungus spores could remain or spray the soil with special preparations for roses, and then put fresh mulch.
