How to get rid of mold on trees

Will This Green Mold (Lichens) Growing on My Tree Kill It | by Tree Removal Services

Do you have a mold-like greenish substance growing on your tree trunk or branches? Don’t break out the pruning shears so fast, you may be surprised to discover what it is and what it means. gathered the following information about what lichens are, where they grow, and what they mean.

Lichens are formed from a symbiotic relationship between a fungus and an algal partner and can grow on nearly any surface.

The Fungal Partner — The filaments of the fungal partner (mycobiont) surround and grow into the algal partner’s cells. The fungal partner represents the majority of the lichen’s physical bulk and shape, forms the outer surface for protection and support, and collects both moisture and minerals from the air.

The Algal Partner — The algal partner (phycobiont) possesses chlorophyll used to make food when exposed to sunlight, thus creating the symbiotic relationship needed for the two species to thrive as one.

Lichens differ from plants in that they do not have leaves, stems, roots, or a waxy outer surface to regulate its water content. When dew, mist, and rain are present, the lichens continue to grow. In summer or during dry periods, they will lie dormant waiting for the next rainfall.

When moisture is unavailable, lichens may suffer a complete loss of body water and become brittle. During these times, pieces may break or flake off, settling in a new location, and later growing into new lichens. When moisture becomes available again, they quickly absorb water, becoming rehydrated, soft, and fleshy again.

Lichens can adapt to their location and can be found in nearly any environment growing on trees, stones, wooden decks, glass, and any other surface that combines sunlight and moisture.

Lichens are commonly found on trees and are frequently misinterpreted as being a sign of decay within the tree. Unlike the fungi that feed off of a tree’s decaying body, the rhizines (multicellular root-like structures) of lichen only serve to anchor its body to the tree, rarely penetrating the bark completely.

Lichens do not feed on a tree’s nutrients. They are a self-sufficient organism, producing their own food, therefore doing no harm to the tree.

The confusion begins when a tree starts to die. As the tree loses its foliage, more sunlight becomes available to the lichens coincidentally, and their growth rate increases. Due to this coincidence, many believe that the mere presence of lichens is a signal of a diseased or a dying tree.

A diseased, stressed, or dying tree may have both lichens and unrelated fungal organisms growing on the same portion of the tree. In such cases, you or your tree expert may need to prune away the affected or dead tissue for the benefit of the rest of the tree. In making these types of decisions, you need to be aware of the unique nature of lichens and the difference between those fungi participating within a lichen symbiotic relationship and other fungi separately feeding on the tree.

You can learn more about Warning Signs, Problems and Solutions for Trees by reading fasttreeremovalatlanta. com/warning-signs-problems-solutions-atlanta-trees

There are several differences between fungi and lichen on trees. You can identify a fungus or fungal infection on a tree by:

• Mushroom conks (reproductive structure) on the tree.
• Swollen areas of bark
• Dark streaks are oozing or running down the tree trunk from a knot or wound.
• Cankers are forming on branches or trunk.
• Carpenter ants are establishing a nest within the tree.
• Extreme leaf drop (out of season).
• Chlorosis (loss of green color) of part of or the entire crown.

You can identify a lichen on a tree by:

• A flat green, bluish, or greyish growth along the surface of tree bark.
• The absence of symptoms of a fungal infection.

There is little cause for concern when lichens are found growing on the bark of a tree, but when a fungus is thriving on a tree trunk or branch, immediate action must be taken to prune, treat, or remove the tree.

While lichens may seem to provide little benefit, they are widely studied and used in ways that may surprise you. Lichens are consumed by animals like deer, goats, and caribou, while many species of birds use lichen materials to help build their nests.

Certain species of lichens are used to produce antibiotics, while others are used to create the miniature landscape for scale sized building models and model railroad tracks.

Lichens found on healthy trees should be welcomed as positive indicators of lower levels of air pollution and good quality atmospheric conditions. Lichens tend to die off in overly polluted areas.

Lichens growing on trees may seem like a sign of trouble, when in fact, they are a sign of clean air and do little to no harm to the tree.

In this article, you discovered that lichens growing on trees do not represent a threat to the tree’s health, their benefits to medicine, how to tell them apart from a fungal infection, and their use in creating model landscapes.

Knowing how to identify lichens on your trees will save you from worrying about the dangers of a fungal infection. Furthermore, their presence should be heralded as a testament to the good air quality of your neighborhood.

How to Get Rid of Tree Fungus


Garden / Garden / Weeds

Updated -  /  Tasha Klettenberg

If you have trees and shrubs around your home or in your backyard, you know how unsightly it can be to have fungus growing out of them. Not only is tree fungus hideous, but it can also damage trees and shrugs by breaking apart their structural integrity and attracting additional pests. This can actually be quite dangerous, and we’ll explain why.

In short, tree fungus is something you should try to get rid of, or prevent, if at all possible.

Whether it is powdery mildew, oak bracket, black spot, verticullum wilt (all very common in North America) or any number of other tree fungi, there are a few things you can do about it.

Why Get Rid of Tree Fungus?

Over time, tree fungus will cause trees and shrugs to weaken, leaving the wood and leaves to be fragile and rotten. Although tree fungus isn’t dangerous for humans, the danger lies when the trees become too weak. If tree fungus has been feeding off large trees for a long period of time, their limbs or even entire body may fall over and collapse. This is dangerous for everyone in the surrounding area.

Aside from the potential of collapsing trees, tree fungus may also invite unwanted bugs and parasites. Depending on how far the trees and shrugs are from your home, the bugs and parasites may travel close to your home by invading other plants nearby. At this point, it can be real a health hazard as you never know the type of diseases these critters may carry.
However, most trees and shrugs that grow fungus will not directly harm humans, so you don’t have to worry about that. Fungus, in general, is not good for our health or the health of animals. It is best to avoid and eliminate it.

Dealing with Tree Fungus

Now that you know why you need to get rid of tree fungus, let’s talk about how you can get rid of it. Here are four methods you can use:
1. Preventing tree fungus from growing
2. Baking soda and water
3. Clorox bleach and water
4. Cutting off infected limbs

Prevent Tree Fungus from Growing

The first and best method of getting rid of tree fungus is preventing it from growing in the first place. To protect your trees and shrugs, you need to understand when they are susceptible to tree fungus. Tree fungus can start to grow and spread because of things you do or don't do. Here are some tips:

Prune Trees at the Right Time

Many people prune (trim) their trees and shrubs to keep them healthy and strong. Pruning trees at the right time will actually make the tree healthier and more beautiful.

However, pruning them at the wrong time increases the risk of tree fungus. Very generally speaking, the best time to prune your trees is during the winter months while they’re dormant. If you prune trees during the warmer months, the wounds on the trees will not heal as fast as they should. This makes them vulnerable to catch diseases.

The kicker is that the right time prune a tree often varies based on the species, so it is important to do a little research.  For example, pruning an oak tree in the early spring will increase the chances of fungus entering, while other species are best pruned during this time.  Again, generally speaking, winter dormancy is usually a good time to prune.

Do not Over-Water Trees

Another way to prevent tree fungus is to not over-water them, especially if it rains a lot in your area. Over-watering of trees and shrugs will cause their roots to rot, and this invites fungi to colonize inside the rotting roots. Once the fungus starts to colonize, it will start moving upwards into the tree, and that’s when you will start to see the fungi spreading.

The best way to water a tree is to give it a deep soak about once a week. Watering a little daily means that the tree roots and base are constantly wet — a recipe for fungus!  Note – on newly-planted trees, you need to water more than weekly.  But once the tree is established, throttle back.

Use Sharp, Clean Gardening Tools

When you use the same gardening tools over and over, they start to get dirty and may pick up bacteria and parasites, especially if you don’t clean them. Then when you go to use these tools around your trees and shrugs, you’re directly inviting unwanted fungus spores to grow.

Dull tools can also be bad for your tree, because they do not give the tree a clean cut, causing the scar to collect moisture and dirt. They can also carry things that you just want to not have around, like poison oak spores (which can give you the famous poison oak rash even if you are nowhere near the plant).

Use a good, clean cutting tool.  We like the Fiskars steel hand pruner (here on Amazon), a tried-and-true tree tool that can tackle branches as thick as about 1 inch.

Maintain Your Trees and Shrubs

When you have trees and shrugs around you, it’s important to always drain your soils properly and remove dead stems and leaves. You can also use preventative fungicides to prevent potential infections and diseases from growing.

Make sure that nearby plants and trees are not encroaching on your tree.  Air flow is important.  Trim back anything that interferes with your tree’s freedom, and be especially wary of vines that might start growing from the ground up.

Plant your trees in the right place

Every type of tree has planting instructions, and a situation that is best-suited for that particular tree.

Some trees like full sun in order to grow, others need to be protected from sun or they might get scorched.  Some trees like to have plenty of moisture in the soil, others will die if they have chronic “wet feet”.  It is not one size fits all.

I once planted a few trees in my backyard because I liked the species, knowing full well that I was going against the ideal planting instructions and the tree’s own requirements for light and water.   I thought that with proper care, I could defy the odds and make these trees beautiful.  As a result, the trees were stunted forever, and way more prone to disease than other trees.

Ways to Get Rid of Tree Fungus

Use a Fungicide Designed for Use on Trees and Shrubs

A good fungicide can do wonders on tree fungus.  Just make sure it is designed for use in the landscape, on trees and shrubs.

The product we like is Natria Fungicide (find it here on Amazon) which seems to work on nearly any kind of outdoor fungus.  Apple tree rust, regular leaf fungus, even lawn fungus.  We also know from personal experience that it is quite effective on powdery mildew, the annoying affliction that likes to target popular magnolia trees.

It comes in either concentrate or an easy spray bottle.  Just make sure you apply it when it is cool — on a not-so-hot day or in the evening.  Applying during a very hot and sunny day could cause it to burn the plant or tree it is being applied to.   You also need to really saturate the tree bark, in order for it to work correctly.

Baking Soda and Water

Another method to help get rid of tree fungus is using a baking soda and water mixture. Baking soda is a great gentle solution that prevent fungus from growing because it acts as an antifungal agent. Keep in mind that this solution will not completely get rid of tree fungus. It will simply act as a preventative to stop fungus from growing. You’ll need to use another method to get rid of the existing fungus. Here’s how you can create your own baking soda and water spray:

  1. Grab pure baking soda at a local convenience store and one-gallon container of water.
  2. Grab a sprayable container to hold your baking soda and water mixture.
  3. Pour your water into the container and add one tablespoon of pure baking soda.
  4. Add one half teaspoon of plain dish soap.
  5. Shake your container thoroughly to mix everything together.

Now that you have your baking soda mixture, water your trees and shrubs and then wait 2-3 days before applying your baking soda mixture. It’s important to not apply the solution when the fungus is fully exposed to the sun. Spray down the infected area as well as around the tree for best results.

Bleach and Water

The third method to get rid of tree fungus is using a bleach solution. Bleach inherits similar components to chemical fumigants which will help kill and prevent the spread of fungi on your trees and shrubs. Follow these steps to create your own bleach solution for tree fungus:

  1. Grab 1 cup of Clorox bleach and one quart of water.
  2. Grab a sprayable container to hold your bleach and water mixture.
  3. Pour your water into the container and add one cup of Clorox beach.
  4. Thoroughly mix your solution by shaking the container or using a long spoon.

Like method two of this guide, water your trees and shrubs and then wait 2-3 days before applying your bleach solution. Apply the solution to the affected areas when they are not fully exposed to the sun. Apply the solution two to three times a day until the fungus gets killed off.

Note that very young or small trees might be more sensitive to strong chemicals like bleach. Consider using the baking soda method instead.

Remove Affected Limbs

Another method to get rid of tree fungus is removing the limbs using a bleach and water solution. To use this solution, create the solution from method three. Simply grab one cup of Clorox bleach and one quart of water, and then mix them well.

This time, don’t use a sprayable container as you’ll actually be using a saw or a similar cutting tool to remove the infected limbs. Grab a container and pour your bleach solution inside. Now, submerge your cutting tool for at least five minutes and then rinse it off with clean water.

Carefully cut off the limbs of your tree that are affected with fungi and place them into a disposable bin or container. Keep the fungi away from any healthy trees, shrugs, or other plants. If the fungus is growing near the trunk of the tree, you’ll have to cut into it. Cut it deep enough so that you remove the fungus inside.

After cutting off the limbs, use the Clorox bleach solution or another preventative solution. This will prevent the fungus from growing, and ultimately killing off the remaining fungi. Thoroughly rinse your cutting tool with soap and water as it may be exposed to disease, bacteria, and parasites.

Neem Oil

Neem oil is a natural oil that has many uses.  A natural insecticide, it will help eliminate the bugs that might be creating or spreading the fungus on your tree or shrub.

Much like fungicides, you can apply it directly to the tree’s bark.  It works much like horticulture oil, covering up the spores that create new fungus, before it can spread.  It is easier to apply before a tree has leaves, if you are lucky enough to catch it early.


Use these methods to successfully get rid of tree fungus and prevent it from growing. Having healthy trees and shrugs grow is incredibly valuable and great for the environment. Always take proper care of them to prevent diseases and infestations from growing!

How to get rid of mold on wood with home remedies

At home, the question of how to get rid of mold on wood can be solved in different ways. In the old days, a house infected with a fungus was simply burned, now more gentle means have appeared. Next, we will try to understand the causes of this scourge, and most importantly, you will learn how to deal with mold on wooden surfaces in several ways.

How to get rid of mold on wood using modern and traditional methods


  1. Fighting mold is important
  2. Where does mold come from on wood
  3. Where does fungus and mold grow
  4. What happens if you don’t fight fungus on wood
  5. How to fight fungus on wood

    the best way to fight mold and fungus

  6. Means for fighting mold and fungus
  7. How to remove mold from wood in a sauna
  8. Black mold
  9. Conclusion

Fighting mold is important

The problem can be safely classified as eternal, since it is completely unrealistic to get rid of fungus and mold on wood. The thing is that the air of any living space contains spores of various kinds of fungi.

As long as their concentration does not exceed the norm, this vegetation is not dangerous, but as soon as the spores get into favorable conditions (dampness, heat and lack of ventilation), they begin to develop, create colonies and release billions of new spores. In this case, the wood is actively destroyed, and the contaminated air becomes dangerous for human life. Therefore, the fight against fungus and mold is endless, but not hopeless.

How to get rid of mold in a tree in a wooden house

Where does mold come from on a tree

When there is already a problem, before removing mold from a tree, it is desirable to understand the reasons for its appearance, otherwise the destroyed colony will arise again.

  • It is useless to get rid of spores in the air, they were, are and will always be.
  • The second reason for the development of infection lies in the vulnerability of wood, freshly sawn and untreated wood is most often affected by the disease.
  • If one rotten plank gets into a pile of healthy wood, the problem will quickly spread to all nearby material.
  • High humidity and heat greatly increases the likelihood of a problem. For the development of the colony, the optimal temperature is considered to be 25º - 70ºС.
  • In addition to heat and humidity, colonies develop due to poor ventilation and lack of sunlight. In a well-ventilated, bright room, mold does not occur.

If the room is poorly ventilated, then there is a high probability of growth of the fungus in the corners and in secluded places

Where fungus and mold grow

Fungus and mold can settle on any building or finishing material, but this living creature likes wood the most. A porous, biologically active and warm base is a favorable environment for the appearance of a problem. There are a number of places where getting rid of mold is especially difficult.

  1. Corners around window frames, especially if the frames are solid or windows rarely open.
  2. Room corners.
  3. If the outer walls are thin or do not have waterproofing, then there is a risk of fungus growth indoors.
  4. Place behind and under bulky furniture;
  5. The basement and underground of any home are often the first to be at risk.
  6. Mold can develop in insulated, well-insulated attics.
  7. In case of violation of the installation technology of the roofing pie, a fungus can settle between the layers.
  8. It is especially difficult to remove mold from wood in a bathhouse, because if you do not take measures in advance, then this room is ideal for the development of fungus.

Important: in wooden houses, the problem usually appears in the basement or underground and from there spreads throughout the house.

In the absence of proper protection, any place in the house can become a breeding ground for fungus

What will happen if you do not fight the fungus on wood

innocent prank compared to the rest of the trouble.

The appearance of a light fungal coating quickly develops into a colony. For residents of the house, such a violent development of such vegetation can stimulate or cause an exacerbation of such diseases as:

    • asthma;
    • Allergy to various foods, materials, pollen, etc.
    • emphysema;
    • tuberculosis;
    • inflammation of the respiratory tract, up to pneumonia.

On a concrete surface, the fungus can live for quite a long time, and having settled on a tree, an intruder destroys the base in a couple of years. First, the top layer is affected and the color of the wood changes.

If after that the owner is in no hurry to remove the mold, then the problem penetrates deep and can pass through the entire massif, at this stage it is already useless to treat, the board, beam or log must be changed, otherwise the wood will completely rot and collapse in six months.

How to deal with fungus on wood

To remove mold from a wooden surface, there are many professional and folk remedies, but before removing mold from wood, you need to get rid of the root cause of its appearance.

Prevention is the best way to fight mold and fungus

A good owner starts fighting mold long before it appears. There are a number of simple recommendations, following which you can prevent the appearance of such vegetation in the house.

  • First of all, you need to take care of adequate ventilation. Forced ventilation is installed in houses made of SIP panels and similar frame structures, natural ventilation is not enough there. The same can be said about cellars, underground floors and baths, forced drying is not required here, but desirable.
  • If groundwater is close, then ventilation alone is not enough, in order to get rid of moisture, it is necessary to equip the external waterproofing of the basement and foundation, as well as install drainage around the house, how to make drainage with your own hands, with detailed photos and videos, see "HERE" .

Waterproofing and arranging drainage in the underground part of the basement and at the foundation level is guaranteed to rid the basement of the house from fungus and mold

  • Inspect the sewerage and plumbing, the slightest leak and even condensate can cause mold to grow and feed fungal colonies.
  • Deep cracks in walls, floors and ceilings can harbor a fungus colony, because in the depths it has ideal conditions - quiet, warm and not blowing. Therefore, the cracks need to be embroidered, treated with an antiseptic to the full depth and repaired.

Tip! To prevent mold from growing behind large furniture, move it away from the walls by 50 mm, and drill a series of holes (diameter 10 - 12 mm) in the back wall of the cabinets at the top and bottom for ventilation.

Mold and mildew control

The mold and fungus removal technology itself is of the same type, first you need to clean the affected area, then treat it with the selected antiseptic and so that the problem does not recur, treat the wood again with a protective agent.

To combat this scourge, there are a number of fairly high-quality products on the market, for example, Aquatex, Pinotex, Element T-0 or Bioshield. The tools are good, repeatedly tested, plus each of them has step-by-step instructions for processing the material with your own hands.

Factory wood preservatives give a guaranteed good result

But these products have several drawbacks, firstly, they are chemistry and often quite harsh, secondly, the price of such liquids is far from always acceptable, and most importantly, our people trust trusted folk products more funds.

Folk remedies for mold and mildew
Illustrations Recipe0161 Vinegar

Spray ordinary table vinegar on the affected area and wipe off the mold with a sponge. If the sponge does not wash off, scrape off the plaque with a knife or spatula.

Important! In order to destroy the roots, you need to fill everything with vinegar after cleaning and let it dry, then wash the surface again.

Hydrogen peroxide

Soak the affected area with hydrogen peroxide and leave it on for 10 to 15 minutes. Next, scrape or wipe the mold from the surface with a hard sponge and wash it with warm water.

Baking soda

Take a damp sponge, sprinkle baking soda on it and scrub the affected area. When the work is finished, wash everything with water.


Ordinary whiteness, which housewives use to bleach clothes, can easily cope with mold, but chlorine is very aggressive, you need to work in a respirator and gloves, plus whiteness discolors the surface (burns out dyes).

How to get rid of mold with tea tree oil

Tea tree oil is considered to be gentle, environmentally friendly, and therefore completely safe, plus it smells good.

The recipe is simple, dilute 10 ml of oil in half a liter of water and use a sprayer to apply the liquid to the surface. After cleaning, the same mixture can be applied as a preventive measure.


A glass of white powder is diluted with 2 liters of water, after which the infected surface is washed out with this liquid.

Important! Do not try to mix whiteness or other versions of a chlorine solution with ammonia, with this tool you will not only spoil the tree, but can also cause serious harm to your own health.

How to remove mold from wood in a bathhouse

Bathhouse is a specific structure, it is extremely undesirable to use harsh chemicals here. Therefore, you need to get rid of mold with something safe, as an option, you can clean the pollution with vinegar or soda, and then treat problem areas with a solution of tea tree oil in several passes.

How to get rid of mold on wood in a sauna using tea tree oil

Advice! If you do not trust folk remedies or you do not have time to clean the boards for a long time, you can buy a professional antiseptic for baths and saunas. The cost of such compounds is many times higher, but you get a quick and guaranteed result.

Professional effective antiseptic for wood treatment in the sauna

Black mold

The question of how to get rid of black mold on wood deserves separate consideration, because this type of vegetation is especially difficult to remove. If you do not take into account factory funds, then black mold can be tried to be destroyed in three ways.

For owners of wooden houses, baths and other buildings, black mold is considered one of the serious problems

  1. Take 1 part vinegar, 1 part peroxide and 1 part boric acid. All this is diluted in 4 parts of water. The solution is practically safe and can be used indoors.
  2. Treat wood with copper sulphate solution. It makes no sense to write concentration, because no matter how hard you try, blue vitriol dissolves in water only by 5%. The solution is effective, but the wood is painted in a peculiar bluish color.
  3. Add 50 g of boric acid and 1 kg of salt to 5 liters of water. The surface is treated at least 3 - 4 times.


Getting rid of fungus and mold on wood is difficult, but still possible. All the methods and recipes mentioned above have been tested in practice and work exactly. In the video in this article you will find good advice from practitioners. If you want to share your own experience, please feel free to comment.

The environment is replete with microorganisms and spores of all kinds of fungi, which are in an inert state and are waiting for the right moment. Dampness combined with heat provokes the appearance of mold on the apple tree. At the same time, healthy apple trees can cope with fungal infections. It is necessary to carry out preventive treatments of trees and treat them in time if mold damage is detected.

    • 4.2 In the spring
  • 5 The best remedies for mold
  • 6 Prevention tips

Causes of mold

The following causes of mold are distinguished:

  1. The presence of a wound on a tree is a direct path for fungi.
  2. Excessive humidity and heat.
  3. The appearance of moisture on the bark as a result of untimely or insufficient pruning of the garden, sufficient ventilation is not created.
  4. Failure to take preventive measures: pruning trees, spraying against diseases and pests before and after bud break, use of sprinkling during watering, monitoring the condition of trees, whitewashing trunks from burns when exposed to the sun.

Types of mold

There are the following types of mold:

  1. Sooty - appears on the bark, foliage, branches, fruits in the form of black plaque. This type of mold finds nutrition in the liquid flowing from the tree, and also feeds on the remains of the vital activity of insects such as aphids and moths. Accordingly, insects are less dangerous than the resulting disease. At the same time, fruits affected by dark spots are edible, they simply have an unmarketable appearance, they are poorly preserved (rot quickly).
  2. Powdery mildew, also called white. A white powdery dirty coating is formed on the foliage, after which it acquires a brown tint, the branches dry and turn yellow, there is no fruit set.
  3. Scab - found in the form of many brownish spots with a rough structure on the fruit. The reason is excessive humidity, stagnant air in the foliage area. At first, it is imperceptible, the mold infects the leaves, and greenish spots with a brown tint form on the inside. After the mold moves to apples.
  4. Lichen is not dangerous for the tree because it has no roots, the fungus does not drink apple juice. This type of mold lives with single-celled molds that feed both of them. There are various colors: gray, with a hint of silver, yellow with a greenish tint, blue. The formation of this type of mold indicates that the tree has weakened. At the same time, it should be taken into account that pathogens of certain diseases and insects survive the winter well in them.
  5. Red - appears in the formation of red sores on the tree with a brownish tint. It is called cytosporosis - a fungal infection of the cortex. It affects the tree in a similar way to black cancer. The only difference is that with cytosporosis, an apple tree can be saved. In case of delay, the infection will spread rapidly. All fruit crops will be in danger. On the affected bark, plates of a whitish, black or grayish tint are visible. Upon closer inspection, the threads are distinguished.
  6. Black, called cancer, such a disease leads to the death of a tree within five years. The danger lies in the fact that the whole garden can suffer. Cardinal measures: remove and burn all affected branches, treat wounds with a 5% vitriol solution and spread with var.

How to get rid of mold on an apple tree

When mold appears on a tree, it is important to find out the cause of the damage, what mistakes were made. This is the only way to overcome the fungus and save the garden from danger. It is important to determine the line of treatment. Although young apple trees are less susceptible to damage, the fungus can also overcome them.

Young trees are easier to treat, it is necessary to treat them with active chemicals, regardless of the timing of fruit collection. Bordeaux liquid, other preparations containing copper are used. These include: "Skor", "HOM", "Topaz".

Mature trees on which there is an ovary, you can try to treat with a solution of soda (170 g per 15 l). If after processing the tree throws off the fruits, it's not scary. It will be easier for him to endure the winter by giving away the harvest. In autumn, the trees need to be rejuvenated and the trunks whitened as much as possible.

On the roots

Most often, the root is not attacked by mould. It can be affected by a bacterium that can cause black cancer, the most dangerous disease.
On the trunk

When mold appears on the trunks of an apple tree, it is necessary: ​​

  • first you need to determine the degree of damage: open the bark with a knife, if it falls off well, has a brownish tint, friability, eggs or larvae are present - the affected area is extensive, it is necessary to treat wood;
  • clean thoroughly with a scraper, spatula, brush;
  • collect and burn the waste;
  • spray with a copper-based product;
  • it is recommended to wipe the trunk and large branches with the composition: ash, salt, grated laundry soap (6:1:1 parts) and boil.
  • disinfect with protective putty.

On leaves and branches

For the preservation of foliage and branches it is necessary: "(400 g per 15 l).

  • In the last days of April, treat with Bordeaux liquid 4%, copper oxychloride or cuproxate. In case of damage by powdery mildew, it is recommended to treat with the preparation "HOM".
  • Bordeaux liquid 1% concentration is used during the formation of buds and after the flowering process.
  • After 20 days after the flowering processes, the tree is treated with a suspension of flatan, cineb or captan.
  • To avoid re-infection next year, it is recommended to collect fallen leaves and dig up the ground.
  • Some gardeners recommend using traditional methods, but with severe damage they may not be effective. Treat with infusion of chamomile, ash and garlic. They are harmless, are an excellent remedy for aphids.

    On fruit

    Infection of apples may be fruit rot. In this case, not only the fruits, but also the foliage are affected. It is a very dangerous disease, since it is found after the flowering process, when spoiled fruits appear on the tree. Rot infects apples before they ripen. The best solution to the problem is to prevent the disease. Required:

    • make a prophylactic treatment with Nitrafen emulsion 220 g per 10 l of liquid, DNOC - 200 g per 10 l, colloidal sulfur suspension - 120 g per 10 l;
    • pick up affected fruits and destroy them, dispose of them away from the orchard;

Or prepare a Bordeaux liquid: copper sulfate (120 g) and quicklime (210 g) for 12 liters. Such treatment is effective against diseases.
    2. Before and during bud break in the last days of March - in the first of April. Pests wake up, and this is also another effective mold prevention. It is recommended to treat with Bordeaux liquid (more than 2 weeks have passed since the last spraying) or an ash solution. The drug "Guardian" (3 ml per 5 l) is very effective in fungal diseases. During flowering, the apple tree is not sprayed so as not to harm the bees. But if the damp warm weather lasts for a long time, the risk of mold development increases. It is recommended to use "Fundazim" 12 g per 5 liters.
    3. After flowering to prevent powdery mildew, scab. Folk ways: infusion of ash. Of the drugs, the result will be: a mixture of Antigusin (4 ml), Boxwood (3.5 ml), Capture Oil (45 ml) and Antiklesh Pro (12 ml).

    Diseases become active at any time, therefore, one should not be limited to one-time spraying.
