Diseases of apple trees in the photo and methods of their treatment
Rust on the leaves of the apple tree, as well as other defects on various parts of the plant, indicate the presence of a disease. If such symptoms are found, urgent action should be taken.
Varieties of apple diseases
Today there are a very large number of apple tree diseases. The most common are the following varieties:
- black cancer;
- scab;
- powdery mildew;
- fruit rot.
Each disease is dangerous in its own way. When the slightest signs of disease appear, you must immediately start treating the plant.
Black cancer
- the appearance of black spots on the leaves - their number and size are growing every day;
- the presence of black rot on fruits;
- darkening of the tree bark, the appearance of multiple cracks on its surface, its turning in the opposite direction.
Treatment of black apple cancer must be carried out with bordeaux liquid - it treats the affected areas on the trunk. But this operation must be performed only after the trees have flowered. In order to avoid the appearance of a disease of this kind, it is worth carrying out preventive work. This will make it possible to preserve the maximum amount of plants.
Black spots on the leaves of the apple tree cannot be eliminated, but you can simply prevent their appearance:
- fight small pests;
- fertilize and disinfect the soil appropriately.
Often, this kind of measures becomes enough to prevent black cancer from infesting the tree. If there are any plants on the site that were nevertheless affected by this disease, it is necessary to cut off the black areas of the bark and branches, and then burn them outside the site.
Scab
One of the most frequent questions gardeners ask: scab on an apple tree - how to deal with it? This disease is quite simple to define. It appears almost immediately after the plant is infected. The first sign of infection is rust on the leaves of the apple tree. If possible, it is necessary to start fighting the disease as quickly as possible.
This type of disease is the most common fungus. It is possible to save a tree only in case of timely detection of infection sites. If you start the disease too much, then you can say goodbye to the plant. It is best to familiarize yourself with the signs of apple disease in advance from a photograph.
The fight against this type of disease should begin in early spring and be carried out using the Topaz composition as follows:
- the substance is diluted in a ratio of 2 ml per 10 liters;
- even before flowering, the tree trunk is processed with this composition;
- after flowering, the plant also needs to be processed.
You can also use Hom instead of Topaz. It should be diluted at 40 g per 10 liters of water and sprayed on the stem of the plant before and after flowering. Colloidal sulfur, which is diluted in an amount of 80 g per bucket of water, also gives excellent results. It is very important not to overdo it with the compositions indicated above. This can burn the bark and foliage.
Powdery mildew
A disease such as powdery mildew is dangerous because it damages young shoots and buds of an apple tree.
Apple leaf disease of this type is characterized by an extremely rapid spread. A tree under the influence of the fungus that causes the disease can die in literally one month.It also often happens that the mycelium survives a cold winter in the trunk of a plant and, after a thaw, begins to act with renewed vigor, destroying the fruit tree from the inside.
To treat apple trees from a disease of this type, the following drugs can be used:
- "Topaz";
- "Speed".
The compounds in question should be diluted in a quantitative ratio of 2 mg for every 10 liters of water. In this case, the treatment is best carried out with a special spray bottle in early spring, before flowering. After that, without fail, it will be necessary to process the tree with copper chloride, for which a drug called "Hom" is perfect. It should be diluted in an amount of 40 g per bucket of water.
Sometimes, after performing the above actions, the plant visually looks normal, there are no signs of the disease on it. It is imperative to collect all the fruits. To minimize the likelihood of a relapse of the disease, you should also perform the treatment with Bordeaux liquid - a solution of 1%. A solution of copper sulfate is also perfect. It should be mixed in the amount of 50 g per bucket of water, while adding 20 g of liquid soap.
Fruit rot
Why do apple leaves turn yellow in June? The reason for this may be the most common fruit rot. It affects not only the apples themselves, but also the leaves. However, the main sign of the presence is the presence of severe damage to the fruit.
This type of disease is the most dangerous, since its presence can be detected only after the end of the flowering process, when damaged fruits are found.
Fighting fruit rot is quite difficult - it damages apples even before they ripen. The best way out of the situation is to simply prevent the onset of the disease.
It is quite simple to do this: preventive treatment should be carried out using a conventional nitrafen emulsion - this substance is diluted in an amount of 200 g per 10 liters of water.
The following drugs are also excellent for combating a disease of this type:
- DNOC - 200 g for every 10 liters of water;
- suspension of colloidal sulfur - 100 g for every 10 liters of water.
Another way to minimize the likelihood of developing a disease of the type in question is to collect all rotted fruits and systematically destroy them. This operation should be performed daily. Dispose of apples as far from the site as possible. It is advisable not to bury them in the ground and not throw them away, but simply burn them. This way you can completely destroy the pathogenic fungus that leads to the appearance of rot.
To avoid a situation in which the leaves on the apple tree become covered with brown spots, various kinds of preventive work should be performed.
First of all, these include inspection of the tree trunk. The barrel should be as flat as possible, the presence of any cracks and other defects is not allowed. This also applies to leaves and fruits. Even if the symptoms of any diseases appeared only on one or two leaves or apples, the entire set of measures should be taken to disinfect the plant. Perhaps this will save him from death.
It is quite difficult to grow an apple tree, despite the unpretentiousness of most of its varieties. That is why it is necessary to closely monitor its condition as closely as possible. Since with untimely treatment for the diseases described, you can lose not only the crop, but also the tree itself.
hello! I need your help, fruit apple is 3 years old,
an unknown disease appeared on the branches and trunk
photo attached, please reply as soon as possible
From the photo, your disease looks like European or common cancer. It affects the trunk and forks of the main branches. The disease is fungal.
Cut out sagging and bulges to healthy wood. Treat open sections with 5% copper sulfate solution, 3% nitrophene or 8% formalin.Close the wound with Tikurilla antiseptic and open-cut sealant. Use fungicides against scab. It can be cured only at the initial stage of the disease.
At the same time, protect the bark of the tree from mechanical damage, where the infection can move. Protect the tree from frost damage and sunburn of the bark by whitening the trunk and skeletal branches. Lime should be in a concentration of 2 kg per bucket of water, add 20 grams of wood glue to the solution of 100 g of copper sulphate for better adhesion.
Hello! I also need your help, the fruit apple is 3 years old,
in the spring an unknown disease appeared on the trunk
photo attached. I ask you to answer as soon as possible How to treat and whether it is necessary to treat and what is it?
Good day! Your apple tree has cancer. Can be treated. To do this, first clean the affected areas (the lower part of the trunk and a dark spot at the top). Perform the removal of the affected areas of the bark gently, but do not leave the sore spots unattended. Collect the cut pieces of bark and burn. Treat wounds with linseed oil or oil paint. For processing, you can use garden var or pharmacy brilliant green. Disinfect the entire tree with a solution of copper sulfate or with a preparation containing copper. Check the foliage. If there are lesions, treat with Bordeaux fluid. Good luck
Natali, thanks for your help!
Hello. I need your advice, is it still possible to cope with this misfortune?
Good day! Your apple tree is deeply infected with cancer .. If you don't take any action, it will die. You cannot do without radical measures. First, do a deep cleaning of the affected area. Remove everything down to healthy tissue. Collect what you clean into a container for further incineration. Judging by the state of the tree, some branches will still have to be removed and also burned. Treat fresh wounds with linseed oil or oil paint. You can grease with pharmacy brilliant green and cover with garden var. Next, disinfect. You can't do without her. If the tree overwinters, it will be possible to form a new crown from the remaining branches. Treat immediately. Good luck.
Good day. Thanks for the answer. The beginner gardener himself - I will try. It is raining now and according to forecasts for another week. In this situation, can I work with her?
Natali, and How do you need to disinfect?
The cleaned wounds are disinfected with a 1-2% solution of copper sulfate (10-20 g per 1 liter of water The wounds cleaned from the lesion are disinfected with a solution of copper sulfate 10 g per 1 liter of water. Fungicides will help to suspend the development of cancer in the garden plot. If there are no trees growing between the trees vegetables, do the processing both on the crown and on the ground right now. Next, be sure to process with copper or iron vitriol after the foliage has fallen in autumn and early spring, before budding. and burn. The defeat can spread to neighboring fruit-bearing trees. It is too early to despair. I can’t see the whole tree, but I’m sure that you removed the worst part. I don’t write the names of fugicides, there are a lot of them. At the moment it is necessary to use a drug of contact action, and in the fall of systemic ...
Thank you Natali? I understood.
Yes, this is the most problematic area on the center conductor. I am waiting every day for a parcel with drugs. Two days ago, it was still possible to process it with a 1-2% solution of copper sulfate.
Two years ago, a sprout appeared from the base of the trunk, and it was not very bad. Maybe he has some kind of perspective?
p.s. I combined the answers into one.
There is a prospect if the sprout appeared above the scion point. If the treatment of the affected conductor fails, it will need to be removed and replaced with a new one.Try to keep the central conductor, because it is the strongest and has the best sap flow. Substitution can be considered in the fall. The basic rule of apple cancer treatment is to do all the stages in one day. Cleaning treatment and protection of cleaned areas from further development of the disease. There is no point in disinfecting unless thorough cleaning is done. The affected tissues are not restored and continue to carry cancer bacteria.
Hello! It is useless to apply drying oil or oil paint to wet wood. As soon as the first sun is about four hours, so that the surface of the barrel dries out, immediately start working. Do not be afraid to remove heavily affected branches. A healed tree will quickly restore its crown if you help it. Be sure to apply a fungicide treatment, and a little later, apply organic fertilizer so that the tree can restore the crown. Good luck.
Hello. Need your help. During preventive treatment of seedlings, autumn-spring planting, he burned the leaves of pear and apple trees with a 2% solution of copper sulfate.
You cannot restore the burnt foliage. Therefore, you need to direct all your actions to the development of new leaves. Seedlings need enhanced feeding with organic fertilizers and preparations to stimulate growth. Treat the crown with Guapsin or Reacom. If the seedlings have even a little living foliage, they will gradually regain their strength. Add not only rotted manure to the trunk circle, but also wood ash.
Thanks for the answer. Unfortunately, drugs for stimulating growth are not available ((there are no problems with humus and ash.
Are there any other options?
There is little doubt. Please post a photo and do not rush to use humus for now. You wrote that the seedlings were damaged. Is it a bacterial burn?
On saplings he treated wounds after pruning into a ring and on scions made in the nursery (healed poorly). Sections before putting putty with garden varnish were treated with vitriol solution. I didn't go to the site today, it rains again. I don’t know the state. Yesterday I was pouring it with running water. On the columnar apple, the leaves turned black by 90%; the leaves of pears were partially 25-40%. As an opportunity I will take a photo. Most likely, this is my jamb (((I managed to find on the internet and order only Epin and Zircon (read on the forums)) What do you think will help?
In your case, processing should be carried out only in problem areas, without affecting the delicate foliage of young plants. Of the drug you have chosen, I am personally impressed by Zircon. Be careful not to overdo it with fertilizers. The severe damage to the apple tree inclines me towards a bacterial burn.
Hello. In the spring I planted a columnar apple tree. For me, she was so accustomed. The most had to leave for a month. Upon arrival, I saw her like this. What is it? Can't you save already?
Your apple tree is very sick. Treat immediately with a contact fungicide, after removing the heavily affected leaves (they need to be burned). Then, on the second or third day after treatment, apply a gentle fertilizing if you did not apply fertilizer during planting. On the sheet, do the treatment with the growth preparation Guapsin or Reacom. you will have to fight for a seedling.
And what fungicide to treat? I'm new to this, I don't know anything. What could make you sick interesting?
I would recommend that you contact your local gardening store. Each region already has its own proven effective means. A competent vendor will give advice and advice on a fungicide (there are a lot of them).To understand why your seedling got sick, you need to carefully analyze your actions from the moment you select a seedling, prepare a planting site, apply fertilizer and until dry leaves appear. Perhaps a lot of organic matter was introduced or there were strong fogs and hot days with a scorching sun.
This is what appeared in our garden on an apple tree. How to deal with it?
The apple tree is already old or badly neglected. It looks like cancer. Read the comments. They contain recommendations for dealing with the disease. To make a specific recommendation, you need a photo of the entire tree.
Yes, the apple tree is already old, has three trunks, one in the picture and only he is amazed.
P.S. I attach a photo of the whole apple tree.
Thoroughly clean the affected apple tree trunk. all affected tissues should be removed with a small capture of healthy ones. Treat fresh wounds with a solution of potassium permanganate, and after drying with a garden varnish. Burn off cut pieces of bark and wood. Pick up a fungicide and treat the entire tree. If there are fruits, processing is best done after harvest, but before the onset of frost.
Please tell me why on the Simirenko apple tree the fruits became very small, literally 2-3 cm in diameter, and there are very few of them, although at first they bore fruit normally?
The reasons are crown thickening, insufficient watering and root nutrition. In the fall, add grape cake to the trunk circle after pressing for juice or wine. This is for apple trees only. Prune the apple tree if there is a dense crown or an old tree. Establish watering and fertilize. Watering is especially important when the fruit is ripe. Check the trunk for pests under the bark. Open the moves with a knife, make processing and cover with garden var.
Hello.
Two apple tree seedlings, bought and planted in spring (photo of one of them). The trunks are green, and the buds are still in "hibernation" (((. There is a suspicion that the roots were frozen. And winter is just around the corner.
Why waited so long! Dig out the seedling and start revising the root system. Remove damaged roots. Disinfect the remaining live part of the roots with a solution of potassium permanganate or other means. Soak the roots in a rootstock or other root growth medium. Prepare the landing site by carefully spilling it with a hot potassium permanganate solution. Add fertilizer to the soil. Plant a seedling. If you're lucky, the apple tree will come to life in the spring.
Hello! Help save the apple tree. The bark is cracking on the trunk and branches. The weather is rainy, and in places where the crust is cracked, it peels off like wet rot. The apple tree is about 10 years old, bears fruit for 1 year, that year there were only barren flowers, and this year there are about 15 apples. The apples have been very tasty for a long time, I would like to save the apple tree. Thank you very much in advance.
What's on my apple tree, some white balls?
There are white balls on the trunk of the apple tree. What are they?
Hello! The parents have an apple tree in the garden. And it bears fruit well, and the apples are large. But there is one problem, we cannot find the answer to it anywhere, and this is the first time parents see such a thing. Apples are baked on the apple tree. What it is?
It would be nice to see the tree. The reason for this is most likely the deep pruning of the tree, which leads to the appearance of a small amount of foliage. after all, it is the foliage that protects the fruits from the hot rays of the sun. When pruning, remove only the most problematic branches (intersecting with each other, broken, thickening the crown inside). Do not touch the branches on the outside of the canopy to create a protective barrier for the fruit.
Hello. Now is the beginning of May and my apple tree does not give leaves, does not bloom.In early April, the tree was pruned. The sections were treated with pitch. A crack appeared on the trunk under the fork of the skeletal branches several years ago and it was growing. It was rotting there. My brother cleaned everything out, processed it with pitch and the tree was whitewashed twice. And the kidneys still don't open. As if juices do not get into them. The branches are alive. And the kidneys are dry. Will my apple tree die? Tell me what to do?
Try to treat with a growth stimulant, Apply fertilizer to the trunk circle, abundant watering.
What kind of disease and how to deal with it?
This is not a disease, but aphids. Fungicide treatment is required. Also, install a trapping belt on the tree to block the path of ants - carriers of aphids.
What kind of disease and how to deal with it? One more photo
Please tell me what kind of disease it is. In the photo where the trunk is, the bark is easily detached.
What kind of tree and when did you discover the problem?
Peeling of the bark occurs as a result of freezing of the tree.

Hello! I need your help, fruit apple is 4 years old,
an unknown disease appeared on the apple tree
photo attached, please reply as soon as possible
Insert a photo.
Good day. I have exactly the same problem with apples and pears in my garden. (the neighbors went on quince). What is this disease and how to fight it.
hello, I need help. fruit apple tree for many years about 7. the other day I noticed a place on the trunk that rots under the bark. the bark itself is intact, but I faked it under the rot of the trunk. As such, I did not find the disease according to the above signs, if the photo. please tell me how to cure
Good afternoon. Help, what happened to the apple tree?
Your apple tree is sick with rosette. This is an infectious disease and so far has no effective ways of fighting. The tree will have to be uprooted and burned. You cannot plant anything on the site of uprooting for at least a year. Unfortunately, your apple tree will no longer produce good fruits. Some varieties continue to bear fruit, but the apples are tasteless. To avoid the disease of other trees of apple and pear trees in the spring, treat the buds with 5-8% solution of ferrous sulfate or 3% solution of copper sulfate.
1. Do not waste time and remove the tree, because the treatment will not give the full effect, most of the trunk is affected and exposed. 2. The initial stage was frost damage. Buy only zoned varieties and prepare your garden in the winter.
Thank you for your reply. I will use the recommendation.
Hello, please tell me the apple tree resets the whole color for the second time. It bloomed very well and now the whole color is covered with some kind of rust and dried up. This year all this has spread to the neighboring apple tree. What is it ???
Your apple tree is infected with a viral disease. This is most likely moniliosis. The tree needs urgent treatment. Use now 1% Bordeaux mixture solution. in the spring on the kidneys and in late autumn, do the treatment with a 3% solution. In addition, the tree is strongly weakened and needs good feeding.
Hello! In the spring, we bought an apple tree sapling in the store, it had leaves and even a color, she waited a very long time for planting in the veranda of the house due to bad weather, when she was transplanted to a permanent place (June 2), the leaves were thinned and soon flew around. the sprouts, but already sick and in the holes, were treated first with a solution of soda (June 19), and later (June 21) with Topaz, Now the leaves are still sick and new buds do not bloom. I'm new to growing fruit trees and I ask for help, what happened with my seedling? How can this be fixed?
SOS !!!!
Tell me what's wrong with the apple tree.Young leaves emerge from the apple tree, which then dry out. On the trunk, the bark is cracking, white dots and lichen are visible.
In addition to the written letter
The apple tree crawls out on the trunk, the bark cracks, white dots and lichen are visible.
Using a sharp knife, carefully open the crack and find the worm (it is white). Perhaps there is a clutch of eggs. There may be a stroke under the bark that goes into the trunk. In order not to disturb the tree too much, work with thin wire. After the destruction of the pest, treat with a 1% solution of Bordeaux mixture. When dry, cover the wounds with garden varnish or clay mash.
In the garden, the trees grow no more than two meters and the branches twist to the bottom. What could be the reason?
Insert a photo. The reason may be soil or lack of fertilizer.
Good day! Tell me what happened to the apple tree. An adult plant, in the spring the leaves did not bloom for a very long time, the apple tree looked completely dry. As a result, the leaves blossomed, but now they are somehow sluggish, not blooming. The bark cracks and plaques appeared, like lichen.
It seems that a pest has started under the bark - a white worm. Try to find a move, open it and get the worm with a wire. Perhaps he is not alone there and even managed to make a clutch. All must be taken out, and then the trunk must be treated with Bordeaux mixture. Cover the largest wounds with clay.
Olga, thank you!
Here is such a lichen or mushrooms, I don't know what to call it. Tell me how to treat and what to do.
A lichen has formed on your apple tree. Cover the ground under the tree with plastic wrap and use a wooden scraper to carefully scrape it off the bark. You need to remove the layer until healthy wood appears. Anything that falls on the film must be burned. Treat the wound with iron sulfate. To prevent reappearance in the fall, the apple tree will need to be whitened.

Hello! Need your help. On the apple tree (grade Glory to the Winners - so they told me in the store), the foliage began to dry out and fall off. Please tell me what kind of disease and how to deal with it. I attach a photo of foliage. Thank you in advance.
Hello! The apple tree did not bloom at all this year, thought the weather, frost. But now there is some kind of white mold on the branches, the leaves turn yellow and fall off. What to do?
There is a lichen on the apple tree. If the defeat is insignificant, then it is not terrible. In case of severe damage, it is necessary during a dormant period (early spring or late autumn) to clean the trunk of lichen with a wooden stick in wet weather, or with a stiff brush. Lubricate the lichens with a mixture of clay and slaked lime and remove the entire mass after drying. After cleaning, spray the trunk and branches with a solution of oxalic acid or iron sulfate (3%).
Hello Natalie! Your recommendation from 26.07.2017 to 21.09 concerns my or Natalya's question (request from 26.07.2017 at 10:07)?
Your apple tree has a distinct scab. The following means are used for wood processing: 1. Urea-based solution (500-600 g / 10 l of water). Spraying of trees is carried out in early spring and autumn. 2.Bordeaux liquid (300 g of lime and copper sulfate per 10 liters of water). 3. Twice a year (before flowering and after fruit set), treatment with copper chloride should be carried out at the rate of 40 g per 10 l of water.
Thank you very much for your consultation.
Good day! Help me determine what's wrong with the apple tree? Its main branch starts to dry
I need a photo of a tree. There can be many reasons.
Hello! Please advise on what to do. On the apple tree trunk, longitudinal surface cracking of the bark and damage at the site of the bifurcation of the trunk (photo), the third branch in this place was cut at a distance of 3-4 cm from the trunk (damage around it). The top layer is sticky, apparently the previous owners of the dacha smeared with garden var. How and how we can help the apple tree, according to the owner, the tree is 6-8 years old, the northern synap variety.
I'd love to be wrong, but your apple tree has a black cancer. You can save a tree, but this process is not fast. First, you need to clean off damaged bark and wood to healthy tissue. Then treat with copper sulfate or a good fungicide to kill putrefactive bacteria. Allow the treated areas to dry. After that, process with a garden pitch, but personally I prefer a clay chatterbox.
Good day! Tell me what this disease is and how you fought. Appeared on apple and cherry at the same time
Hello! In my father's garden, the apple tree has been covered with a mushroom similar to chaga for several years (unfortunately, no photo). Every year he removes these fungi, whitens the trunk and branches. Does not help. What can be cured?
Tell a Sajian one-year-old young leaf to curl up.
Your seedling is affected by aphids. Treat now with fungicide. After the end of the growing season (after the leaves have fallen off), treat all the bushes and trees with a solution of Bordeaux liquid or copper sulfate. In the spring, repeat the treatment until the buds bloom, which will help prevent various diseases of trees and shrubs in your area. Pest control must be carried out continuously.
Here is the Sajian himself
ext. evening! Tell me what's wrong with the apple tree. ?
They planted a 3-year-old house in 2014. For two years it gave leaves without flowering. This year there were no leaves, BUT in the fall it sprouted above the graft with leaves and a pink rash appeared on the stems. How to treat with what and when? Attaching photo.
This is a fungal disease - the death of branches. Cut off the entire upper affected part of the apple tree to a healthy and live trunk, treat the cuts with garden varnish. Treat the rest of the tree with a 3% solution of copper sulfate.
Good day!
The question is about the apple tree. Recently (a couple of months), the leaves began to be amazed and gradually fall off. Previously, only old leaves were affected - they did not pay much attention, but now those leaves that appeared last (about 3 months ago) are also affected.
Lives mainly in artificial lighting, there is not enough natural light in St. Petersburg.
Age about 10 months.
We water every day, fertilize periodically. They did nothing else.
How to deal with this situation? Are there any chances of recovery?

Good evening!
Apple trees are constantly sick with scab. And here, after the winter, this is what happened to them. What to do?
Hello! Please tell me what it is on the apple tree and how it can be treated. The apple tree is 4 years old, never bore fruit. Some small cracks appeared and began to grow. Treated with iron vitriol. Now what to do next?
Clean and process with copper sulfate (burgundy). You need to treat it with a liquid mullein if you want to save it. In such cases, I destroy and select only zoned varieties!
Hello! Please tell me what it is on the apple tree and how it can be treated. Yablona is 25 years old, at the bottom of the trunk sap oozes from the crack, like from a birch. What could it be?
Maybe the trunk was cracked from frost. Try rinsing with copper sulfate and covering with clay, you can also bandage the top with an old sheet.
Good evening!
Tell me what about the apple trees. I process from spring to autumn, starting with Bordeaux liquid, then from scab and other diseases. For four years now, nothing has improved.
please tell me what it is: the edges of the leaves on the apple tree turned bright red and turned up, I did not find anything similar among the diseases described on the Internet
Yablona is the third year this year, the buds are swollen but have not blossomed, but on the trunk there are cracks and the bark will peel off
Hello! I need your help, fruit apple 6 ktn, an unknown disease appeared on apple and quince photo attached, please reply as soon as possible
Your tree is already an adult, and if this has not been observed before, then the cause may be a high level of groundwater or excessive moisture in the soil. The second reason is recurrent frosts. The third is bacterial infection. In any case, it is necessary to cut off all affected branches and treat with a good fungicide.
