The apple tree is a favorite tree for most gardeners, and all thanks to the fact that the crop is easy to care for and it is unpretentious. Wide range the use of fruits, leaves and flowers in everyday life further adds to the popularity fruit trees... Apple trees, like other plants, are susceptible to various diseases arising from some negative factors. It is worth considering in more detail the causes of the appearance of brown spots on the foliage, and how to deal with rust on the leaves of the apple tree.

The main cause of rust stains is due to the presence of fungus. Fruit crops planted next to conifers... When they grow, you can find on the leaves of apple trees the appearance of star-shaped outgrowths, on which new spores are formed, which in spring time will be carried around by gusts of wind to garden trees... After infection, the disease spreads through the leaves, shoots and fruits.

The most unfavorable regions for rust on apple trees are the Southern, South-Western, South-Eastern regions of Ukraine and the Republic of Crimea.

The period of active development of the fungus and how it is dangerous for the apple tree

The disease is fungal in nature and, after damage to the tree, interferes with the ability of the leaves to photosynthesize. The yield is markedly reduced due to disruptions in water-mineral metabolism. The tree begins to wither right before our eyes. First, a rusty coating appears, then brown spots appear, then brown ones.

Additional damage is done to young shoots, from which it is already useless to wait for a harvest. Severe damage causes the death of young trees. Most often this happens at the beginning of summer - in June-July.

As soon as a disease is identified, it must be treated, in otherwise you can lose all the fruit trees in the garden. Rust-affected apple trees die in a few years, during which the fungus develops more and more.

Signs of tree disease

Any stains on the foliage, or if the leaves are curled, is a signal to the grower. Rust becomes noticeable from the moment the foliage blooms. Special attention need to be given to plants in the last spring months.

At the first appearance of rust, it is necessary to start treatment in order to prevent the spread of infection throughout the garden and to protect future fruits.

Systemic fungicides to fight fungal infection

To get rid of rust, fungicidal agents are most often used as control measures. They are best used in identifying a disease. The most effective are drugs related to contact or systemic contact.

Namely:

• "Strobe";
• "Topaz";
• "Vectra";
• Tsineba;
• "Poliram".

All funds have approximately the same effect aimed at destroying the fungal colony. There is a defeat of spores, which, thanks to the active particles of the drug, will no longer be able to give rise to fungi.

Universal drugs include systemic fungicides, thanks to which, if used correctly, you can completely heal the garden from red leaves and disease.

As for dosages, drugs are diluted in the following amount per bucket of water:

• "Strobi" - 2 grams;
• Topaz - 2 milliliters;
• Vectra - 2 grams;
• "Poliram" - 2 grams.

All of the above funds are diluted in the same amount, and therefore it is difficult to make a mistake in the manufacture of a medicinal solution. But "Teneba" is added to water in the amount of 40 grams.

Worth knowing: if horticultural crops have been treated for scab, then you do not need to additionally spray the trees from rust. The selected agent will have an effect on both pathogens.

"Topaz"

The tool belongs to powerful drugs to fight the fungus. The release form is liquid or powder. One tree needs 2 liters per 10 square meters. Processing is carried out up to several times with a 14-day break between them.

"Strobe"

The drug has some advantages that allow you to use the product at the time of flower formation. The fungicide poses no danger to bees.

Processing can be carried out at low temperature, high humidity. The agent is effective against various fungal diseases, it is especially successful in combating rust.

"Vectra"

The active ingredient in this powerful drug is called bromuconazole. For young tree two liters of the diluted product is enough. Adult fruiting apple trees are sprayed with a solution of 10-15 liters.

The spray agent can be used a maximum of 3 times and must not be mixed with other products.

Copper preparations for the treatment of the disease

The rust fungus is successfully attacked by the Bordeaux liquid, which is considered to be one of the most well-known methods of treating the disease. A working 1% solution is used.

The first time the garden is cultivated in the spring when more or less warm weather is set. In hot weather, it is strictly forbidden to use the product due to the threat of burns on the trees.

There are also drugs that can fight rust on an apple tree.

"Blue Bordeaux"

Perfectly replaces Bordeaux liquid, has a granular form of release. The product dissolves easily in water. The advantage is that the solution is suitable for use in inclement weather.

Blue Bordeaux destroys pathogenic colonies along with spores. The tool is contact.

"Abiga peak"

The main substance is copper. The drug also belongs to the contact group of substances. The product must be applied to the affected areas of the tree. The drug will not penetrate into the inner layers of the tree.

It is necessary to know that the use of "Abiga peak" is possible only in dry weather. To obtain a working solution in a bucket of water, you need to dilute 50 grams of the drug.

"Cuproxat"

Consists of nitrogen and copper acetate. If you prepare a 0.25% solution, then it will neutralize all fungal spores.

The product is suitable for root watering. The benefit of the product is that it destroys rust and saturates the soil with useful components.

"Champion"

It can be used both prophylactic and remedy... The leaves are covered with a protective layer, and therefore the fungus cannot infect and spread throughout the apple tree.

During the fight against rust, conditions are created that are completely unsuitable for the fungus, but complete destruction cannot be achieved. You need 60 grams per bucket of water. The remedy is contraindicated for use when hot weather is established.

The next group medicines against red spots on the leaves and damage to fruits, preparations containing sulfur are used.

Colloidal sulfur

The greatest effect occurs if the agent comes into contact with the affected culture. It is important to remember that colloidal sulfur is not used when trees are blooming.

"Cumulus"

The main component is sulfur. Convenient form of release, quickly and well dissolves in water. Does not create dust.

Basic biologics

Biological agents for rust stains and apple diseases differ from other agents in that they improve the immune system. fruit crops and increase resistance to fungal diseases. Negative consequences not detected when in use.

The funds do not pose a danger to:

• of people;
• flora;
• insects;
• pets.

When using biological agents, the crop is completely safe for both adults and children.

"Planriz"

If brown rust occurs, it is advisable to use this agent. The drug in the amount of 50 ml is added to 10 liters of water. Planriz effectively fights fungus and enhances the growth of young trees.

"Trichodermin"

Refers to a very common means with a wide range of effects, including successfully combating rust. You can prepare a working solution as follows: dilute 100 ml of the product in 10 liters of water.

The first treatment is done after the buds have opened, and then twice a month throughout the season. When the apple trees begin to bloom, the product is not used.

"Fitosporin M"

Preparation with huge amount positive feedback from gardeners. Trees can be processed throughout the growing season. To obtain a solution, you need to dilute 15 ml of the product in water - 10 liters.

It is possible to process not only trees, but also crops that are difficult to store.

"Fitodoctor"

Has established itself as a successful fungus control agent. To prepare a working solution, you need to dilute 30 grams of the product in 10 liters of water. Fruit trees are processed every 14 days during the growing season.

You can start spraying from the moment the buds begin to bloom. Stop using the product before harvesting the apples.

Tank mixes

Now it becomes clear how to use biological preparations, if you wish, you can make a combination of several funds at once. The use of tank mixtures is a very effective method for combating fungus.

Everything is very simple to prepare, for 10 liters of water you need to take:

• 50 ml Planriz;
• 50 ml of Ekoberin;
• 100 ml "Trichodermina";
• 100 ml of "Gaupsin";
• 30 grams of "Phytodoctor".

If the trees are already affected by the fungus, then it is necessary to process the culture up to 3 times a month, from the moment the buds bloom and until the time of harvest.

Technology and processing time

If the leaves of the apple trees are covered with rust, then you can fight the infection as follows:

1. On the first day, as soon as diseased shoots appeared, they must be cut 7 cm lower than the affected area. Obligatory destruction of the source of the spread of the disease, for example, a diseased juniper. The trunk circle is cleared, the soil is processed copper sulfate in the form of a solution.
2. On the second day, spray the apple trees fungicidal solution... The choice of the drug depends on the growing season. Juniper also needs to be treated with the same product.
3. On the fourth day, potassium monophosphate is used for foliar feeding of apple trees. Use of potassium humate for watering.
4. On the seventh day, the fruit trees, together with the juniper, are treated with the same fungicide that was selected earlier.
5. On the fourteenth day - ash liquor is used for processing apple trees.
6. On the thirtieth day, a new fungicidal agent against the fungus is selected.
7. On the thirty-seventh day - another fungicidal treatment.
8. On the fortieth day - potassium monophosphate is used for foliar feeding apple trees.

After the harvest is harvested, the apple trees undergo sanitary pruning, shoots are removed from the stem or root suckers. It is necessary to whitewash the trunk and the lower parts of the skeletal branches. "Fitolavin" is used to treat trunk circle, mulching is additionally applied.

The beginning of the next season - copper sulfate is used to spray trees when the buds begin to bloom. You also need to process the juniper.
Before flowering begins, apple trees are processed using a tank mix.

Preventive measures to prevent infection

Any disease can be defeated if treatment is started in a timely manner. Protective measures can help keep the infection from spreading. This practice is called prevention, thanks to timely measures taken, garden trees can be saved.

To prevent the formation of fungus, you must:

• cleansing the garden - after the harvest is harvested, it is recommended to remove plant residues to the maximum;
• observance agrotechnical measures(timely processing, top dressing, correct watering);
• the use of fungicides for the treatment of apple trees;
• planting varieties resistant to fungal diseases.

If you inspect fruit crops in a timely manner to identify diseased trees and start treatment on time, losses can be avoided. Any ailment is always easier to prevent than to cure.

Why is juniper dangerous for an apple orchard

Not many gardeners are aware of the dangers of juniper bushes to apple trees. It is in them that rust pathogens arise and remain. Spores of this fungus are carried by the wind or on the legs of an insect to apple trees. V winter period rust is in the needles of a juniper, and in the spring it revives and attacks the apple tree again.

In order to interrupt this process and not be left not only without a crop, but also without the whole garden, you should either get rid of the juniper, or transplant it from the apple trees over a long distance. Young shoots are especially susceptible to the influence of the fungus.

There are waves in the development of the fungus, and they are manifested in the following:

1. Flowering phenophase... Already during this period, small brown dots appear on the flowers. Sometimes they merge, making the flower bordered with rust;
2. Ovary up to 2 cm... During this period, rust affects the foliage;
3. Early July- manifestation on the leaves;
4. End of August, early September - mass spotting and leaf fall.

What is amazed

The leaves of the apple tree are most affected.

Assessing where "rust" appears most of all, you can distribute as follows:

• sheet - from 21 to 70%;
• fruits - from 0.7 to 4%;
• kidneys - from 7 to 36%;
• flowers - from 35 to 40%.

V different years and in different locations, percentages can fluctuate significantly.

Variety sensitivity

Sinap North is one of the varieties that often suffer from Alternaria.

Not all varieties are equally susceptible to fungal attack. A list of the most sensitive varieties has already been compiled, among which are:

• Delicious;
• Sinap north;
• April;
• Forest-steppe;
• Rossoshskoe striped.

Experienced gardeners, seeing the defeat of the garden from year to year, get rid of old varieties and give preference to resistant, new varieties.

Where the mushroom hibernates

The source of the disease is hidden in fallen leaves.

Microscopic mushroom perfectly tolerates low temperatures... A haven for wintering conidia are:

• fallen rusty leaves;
• bark of trees;
• kidneys;
• shoots.

Sometimes it seems that the fungus is infecting healthy leaves, but this is not the case. Immunity healthy plant strong enough to fight. And here the monilious lesion "decimates" it and the Alternaria begins its reproduction.

How to deal with rusty stains

Autumn harvesting of fallen leaves significantly reduces the spread of fungal infections.

Initially, you should strictly adhere to the rules of sanitation and carry out:

• autumn foliage cleaning with removal outside the garden;
• cleaning the old bark from the trunk and skeletal branches;
• keep the aisles under black steam;
• dig up trunks for the winter;
• whitewash the trunk with a lime mortar;
• regular treatment of wood with fungicidal preparations.

How to spray a tree

American and Japanese researchers have proven the greatest effectiveness in alternating copper-containing preparations with fungicides. If the garden was very affected by Alternaria in previous years, then it should be processed every 14 days.

For spraying, a complex of such preparations has proven themselves in the best way: Horus 75 WG, Speed ​​25 EC, Switch 62.5 WG .

1. First processing- the beginning of budding: Horus.
2. The second one 14 days after the first: Horus (cyprodinil - the basis of the drug);
3. Third after flowering... Combine: Horus and Skor 250 EC;
4. The fourth is used during the ripening period: Switch 62.5 WG.

Alternative drugs

The following products are also suitable for use:

• Discore... The active principle is difenorazole. The solution is prepared from 3 ml per 10 l of water. Up to 4 liters of solution are consumed per tree;
• The keeper... The same active ingredient and dilution proportions as in "Discor";
• Strobe... The active principle is kresoxim-methyl. For dilution in 10 liters of water, 2 g of the drug is required.

These drugs are well-deservedly respected by gardeners. They are safe for bees and can be applied during the flowering period and regardless of the amount of rain.

The active substance penetrates the wood tissue even when wetting occurs only on one side of the leaf plate. It can be successfully applied at low and high temperatures, as well as on a leaf damp from rain. Low toxicity for warm-blooded animals makes the product even more desirable for the treatment of the backyard garden.

Experienced gardeners manage to use all of the above drugs for the season. In this case, not a single one can be repeated.

It is especially effective to carry out treatments alternating with Bordeaux mixture.

Bordeaux mixture is the simplest and most common fungicide tested many years of experience gardeners.

Its main active principle is copper sulfate. Getting on the mushroom and its spores, drops containing the base completely inactivate the pathogen ... This drug is old and has been showing its effectiveness for decades.

Some gardeners treat trees with urea ( 5% solution) after the foliage has fallen. Experiments show that such a measure does not reduce the number of pathogenic pathogens and does not reduce its viability.

Processing features

Since the pathogen is ubiquitous, it is on the leaves, bark, shoots, then you need to handle it with special care.

To obtain a positive result, it is necessary to completely spray the entire orchard.

• Can't be lightly sprayed and forgotten for a long time - it makes no sense. Such an event will not help the garden.
• Wood should be processed from top to bottom.... Beginning with outside the tree should go into the inner one, and then return again. Complete wetting of all parts of the wood will guarantee the penetration of the preparation and a decent effect. When processing, you must not forget about the trunk and the near-stem area.... Ground and grass should be no exception. The more thoroughly spraying and full wetting is done, the less likely it is that a second outbreak will return.
• An apple tree in the garden may not be alone. In addition, apple trees can also grow nearby. Every effort should be made to process as much of the site as possible (including the neighbor's).
• Preparing preparations for processing, and after reading the instructions, it is advisable to combine them with acaricidal substances ... Thus, both the fungus and insects that carry the pathogen will be destroyed.

conclusions

Following the rules of sanitation and timely processing the apple tree with a change fungicidal agents, it is possible to achieve that even non-resistant varieties will give wonderful harvest healthy apples.

Video about autumn eradicating spraying of the garden

The spots that appear on the leaves of the apple tree - signal for the gardener... This is how fungal and infectious diseases manifest themselves.

One of the most common is rust.

Noticing red marks, novice summer residents often ignore the first symptoms of defeat. And you only need to find rust on the leaves of the apple tree, look for a solution to how to deal with it.

If you do not prevent the development of the disease, you can not count on a healthy harvest. Apples grow small, tasteless, often rotten.

To regularly collect large ones, juicy fruits, should recognize the disease at the initial stage, apply the correct method of treatment and observe preventive measures, and not at the last moment wonder what to do when they find that the leaves of the apple tree are rusting?

Signs of rust damage

Rust symptoms become noticeable when the leaves are dissolved. This happens in late spring - early summer. Small yellow-green dots of different sizes appear first.

In severe cases, the lesion spreads to the shoots and bark..

As soon as rust appears on the apple tree, treatment should be started immediately, at the first signs of infection.

Apple orchard processing scheme

Important! If in the previous season the apple tree was sick with rust, you should start processing the tree in early spring, even before the start of the growing season.

Treatment scheme:

1. First processing falls in early spring, when the buds have just begun to bloom;
2. The second is carried out before flowering, during budding or after flowering, when fruits have appeared, but have not yet begun to pour;
3. Third treatment carried out 10-14 days after the second.

To defeat the disease, in addition to spraying with antimicrobial drugs, it is necessary to create conditions that prevent the appearance of the fungus.

Rusty leaves on an apple tree - what to do? Treatment and prevention methods

To get rid of from the disease, a system of treatments and preventive measures... By eliminating the sources of infection, you can permanently get rid of Apple orchard from rust.

Infection control work should be carried out in several areas:

Improvement of the orchard

Fungal infections primarily damaged weakened trees. To the immune system the apple tree was strong, you need:

• Rare fruit trees;
• Correct ;
• Timely and competent feeding;
• and culture of sanitization;
• Healthy planting material.

High planting density stimulates rapid spread of the disease.

The optimal conditions for the development of the fungus are created high humidity, so you should not be zealous with watering. If it rains for a long time, the risk of infection of the apple trees increases.

A daily inspection for rust on the apple tree is necessary in order to have time to make a decision on how to fight.

The tree must receive the nutrients that it needs at every stage of development.

If rusty spots are found on the leaves of the apple tree, the application of nitrogen to the soil should be reduced, and the dose of phosphorus and potassium should be increased.

In early spring and autumn, after harvesting, you need to carry out sanitary apple trees.

Shoots and areas of the bark damaged by rust are cut out, and the sections are cleaned.

Affected places treated with a solution of copper or iron sulfate (4-5%), covered with garden putty.

The trunks of apple trees in spring and autumn must be exposed. In case of rust, copper-containing preparations and an adhesive (for example, Green Soap) are added to the garden whitewash.

New apple and juniper seedlings should be carefully examined.

The latter are often brought from abroad already infected.

Destruction of fungus colonies

Bias on clearance summer cottages evergreen shrubs contributed to the ubiquitous spread of the fungus.

Rust pathogens settle on conifers and shrubs. For an apple tree, it is dangerous to be adjacent to an ordinary juniper. Plants cannot be planted nearby.

Colonies form in juniper skeletal branches. Shoots thicken, deformed along their entire length. With prolonged exposure to infection, they dry up and die off.

Myceliums do not live on apple trees, the main disputes cause damage carried by insects or wind.

When rust fungi appear, it is necessary to carefully examine the junipers planted in the immediate vicinity.

Finding colonies pathogen, coniferous shrubs should be treated with a fungicide, cut and burn damaged branches. In case of severe damage to the needles, it is better to destroy the junipers, dig up the ground under it, treat with boiling water and antimicrobial drugs.

Important!: Regular maintenance of junipers will prevent infestation of fruit trees.

In the literature on gardening, there is often a recommendation to remove all coniferous shrubs from the site in order to protect the orchard.

Rust spores can be carried by the wind to a distance of 50 km, so the complete absence of junipers on the site is unlikely to protect against disease.

If the decision to get rid of conifers is made, you should create barriers along the perimeter of the site. For this purpose are used tall trees with a dense crown.

Destruction of spores and the consequences of infection

To avoid the development or renewal of rust infection on the apple tree, proceed to complete elimination of disputes.

Apple trees must be sprayed with antifungal drugs.

The site must be clean from weeds... Many of them are able to become intermediate hosts of rust fungi, for example, sedge, anemone, and spurge.

But presence of bitter wormwood close to sources of infection and spread of the disease affects the development of rust negatively.

Plant residues allow the pathogen to remain on the site for up to 8 years. Affected apple leaves juniper needles and pruned branches must be cleaned up and burned.

Dig up the trunk circles deeply, spill with urea (5-7%), ammonium nitrate (5-7%) and copper sulfate (4-5%). The drugs should be alternated.

Treatments for rust on apple leaves

To fight with rust, preparations based on sulfur, copper and systemic fungicides are used.

Copper preparations

From rust, spraying with Bordeaux liquid is carried out. Apply a 1% solution. Start off spring treatments is possible only after as the temperature reaches positive values.

Do not use the solution for treatments in hot weather, at high temperatures.

If these conditions are not followed, apple trees may get burned.

• Blue Bordeaux- analogue of Bordeaux mixture, in the form of granules. Easily soluble in water. Contact agent causing damage to colonies and spores on infected plants. Suitable for handling in bad weather.
• Abiga Peak – copper-containing preparation, related to contact fungicides... Contains an adhesive, is applied superficially, does not penetrate into wood fabrics. Treatments can only be carried out in dry weather. To prepare a solution, 50 grams of the drug is dissolved in a bucket of water.
• Cuproxat- a product based on copper acetate with a nitrogen content. A solution of 0.25% effectively destroys fungal spores. Suitable for root watering. Possesses fungicidal properties and mineral feeding simultaneously.
• Champion more often it is used not for treatment, but for the prevention of the disease. The drug forms on the plant protective film, prevents infection. On diseased trees, the Champion stops the development of infection, but does not have a destructive effect. 60 g for a bucket of water. Not applicable at temperatures above 25 degrees.

Sulfur based products

Removes rust quickly and efficiently colloidal sulfur solution.

For its preparation, use 40 g of powder per 5 liters of water.

The remedy works when it comes into contact with an infection. During flowering, apple trees cannot be processed.

The drug has the same effect. Cumulus - colloidal sulfur in a convenient form. The product is non-dusty and easily soluble in water.

Fungicides are the main answer to the question: "How to treat rust on an apple tree?"

Good results in the fight against rust give contact and systemic contact fungicides, such as:

• "Strobe"
• "Topaz"
• Poliram
• Tsineba
• Vectra

The actions of the drugs are similar, but the active ingredients are different. This allows you to alternate their application, avoid addictive disputes to one remedy.

Amount of substance per bucket of water:

• Stroby - 2 - 3 g.
• Topaz - 2 ml.
• Poliram - 1.5 - 2.5 g.
• Tsineba - 40 g.
• Vectra - 2 - 3 g.

Now you have learned what to do if the leaves of the apple tree rust.

Important!: If at the time of rust damage the apple trees were treated for other fungal infections (for example, from scab), a separate spraying is not required.

A competent approach to agricultural technology, careful observation of the garden and timely processing of trees will help get rid of many diseases of the apple tree. Rust on the leaves of the apple tree will bypass you, and you will not need to decide how to deal with it.

In contact with

We are used to the fact that only metals rust. Unfortunately, plants are also susceptible to "corrosion". What is apple rust?

General definition

A disease known as apple rust is caused by the fungus Gumnosporandium tremelloides of the genus Phragmidium. It is especially dangerous if you have an ordinary juniper growing in your garden. It is here that the causative agent of the disease appears, which is then transferred to the tree. In winter, spores accumulate, "canned" and live in needles or juniper branches until spring. So they can persist for several years. With the onset of warmth, the spores develop, passing to the leaves of the apple tree. Thus, infection occurs. The disease is very widespread. Plants of the southwestern, southeastern regions of Ukraine, as well as the Crimea, suffer from it more often.

The first signs of the disease

For the first time, symptoms can be detected in the summer, when the foliage of the plant develops well. Convex rounded spots, orange or brown, appear on the upper plate of the leaf. Instead, there may be rust-colored stripes. The spots have black blotches (spermogonia). Places of accumulation of spores - etsidia - are located under them. They look like conical outgrowths. Later, the etsidia open up like a "star", throwing out a mass of the smallest disputes.

At the same time, the lower part of the leaf is affected by yellow spots. With a powerful defeat, the foliage dries up, then falls off. This process is facilitated by high air humidity, windy weather. Then the spores spread faster. The wind can carry them up to 50 kilometers.

All of these symptoms are clearly conveyed by the photo.

Where else does rust develop?

Much less often, the disease affects the branches, trunk, even the fruits of the tree. Young shoots are most vulnerable. They will no longer give healthy growth. The sickest die off. Others are developing. But after 2-3 years, wood cracks in the affected parts. The bark is cracking at the trunk. The fruits are deformed, stop growing, fall off.

Why is apple rust dangerous?

In diseased trees, photosynthesis and metabolism are disturbed. Since spores pull moisture out of the plant, the water balance suffers. This explains the falling off of diseased leaves, fruits, shoots. The plant is missing nutrients... As a result, the amount of the crop decreases, its quality deteriorates.

Control measures

What needs to be done to destroy plant rust with its consequences?

• If a juniper grows in your garden along with fruit trees, then you need to get rid of it! Dig this place deep. You can shield the apple tree with other green spaces. They will delay disease-causing spores. However, infection is unlikely to be avoided.
• If the plants are already infected, then immediately remove all diseased parts (leaves, shoots, branches, fruits). For pruning branches, take 5-10 centimeters below the damage. Then spray with one of the chemicals: Bordeaux mixture 1%, Topaz, cuproxat, 0.4% cineb solution, Vectra. Repeat twice more every 10-14 days.

Apple tree rust prevention methods

• Eliminate the practice of planting fruit trees with conifers in the same area. So you save yourself unnecessary problems.
• In the spring, before the buds appear, it is necessary to clean out the old affected areas until healthy wood appears. Then disinfect them with 5% copper sulfate. After - coat with garden putty.
• Treat trees with antimicrobial agents (fungicides). Spray as soon as the leaves bloom. Repeat after two weeks.

Now you can provide proper care to their fruit trees, and do not allow such a dangerous phenomenon as apple rust.
