Rust on the leaves of the apple tree.

If you notice that spots have appeared on the leaves of the apple tree, then this is a signal that any summer resident needs to pay attention to. This is a sign of the presence of a fungal or viral disease. The most common is the appearance of rust spots. Often, summer residents, especially beginners, do not pay attention to the presence of such spots. And this is completely wrong. As soon as you notice such a situation, you must immediately take action, direction to solve this problem. Rust on an apple tree is a serious disease

The reasons for the appearance of rusty spots on the leaves of the apple tree.

If you were unable to prevent rust stains on foliage apple trees, then, unfortunately, you shouldn't count on a healthy harvest. The apples will be small, usually rotten and tasteless. If you want the fruits to be tasty, juicy and large, then you need to start taking measures to combat this disease as soon as possible, as well as take preventive measures so that later you will not be surprised, but what should have been done when you found rusty spots on leaves.

Signs of rust damage.

It is possible to detect the first symptoms of rust when the leaves begin to bloom. This time falls in late spring - early summer. At first, you will notice how dots of different sizes have appeared, having a yellow-green tint. over time, they begin to grow, acquire a bright red color. This disease is fungal in nature. Pest spores begin to suck out all moisture from the vegetative mass of the fruit. If the disease has become severe, then it begins to spread to the bark and shoots of the tree. He starts taking remedial measures as soon as you notice the appearance of such spots.

How to carry out the processing of trees.

It is important to know that if your tree has already been exposed to this disease, then it is necessary to carry out the spraying procedure with the onset of spring, before the vegetative process begins. The treatment of apple trees is carried out using spraying, which is carried out in more than one stage. For the first time, the treatment is carried out in early spring, as soon as the buds bloom.

The second treatment must be carried out before the flowering process begins, during the budding period or after the end of flowering, when the fruits are already there, but they have not yet poured.

The third treatment is carried out 2 weeks after the second stage.

It is important to understand that in order to cure a tree, in addition to spraying procedures with antimicrobial drugs, it is important to create conditions that prevent the appearance of viruses and fungi.

How to cure rust stains on wood.

To rid the tree of rusty stains, it is important to carry out all measures in conjunction with treatments and preventive measures. If you can find and destroy the source of the disease, then you can protect your site from this scourge for a long time. All actions related to the fight against the disease should include several areas, which we will discuss below.

Most often, weaker trees are most often damaged by various diseases. To improve the immunity of the tree, it is very important:

• Plant fruit trees in a rare manner.
• Water the trees properly.
• Apply fertilizers correctly and on time.
• Take care of the plant and carry out sanitization.
• For planting, opt for a healthy seedling.

If you plant trees too densely, then this can become a provoking factor for the development and spread of the disease. Also, the fungus develops in places where there is a lot of humidity, which is why you do not need to overdo it with watering. If it rains very often, then the risk of getting sick in the tree increases significantly. In order to start fighting the disease as early as possible, it is necessary to inspect the tree every day. The apple tree needs timely fertilization. To do this, it is necessary to reduce the application of nitrogen fertilizers, and, on the contrary, to increase the application of phosphorus and potassium. In early fall and after you have harvested it is very important not to forget about sanitary pruning of the tree. Shoots and those areas of the bark that have been damaged by rust must be removed, and the sections must be cleaned well. It is necessary to treat the affected areas using a solution of copper sulfate (4-5%). Then carry out the treatment with garden putty. In spring and autumn, tree trunks need to be whitened. Anti-rust in the whitewash, you can add preparations containing copper, as well as an adhesive, you can use green soap. Also, do not forget to carefully inspect young seedlings of both apple and juniper, since it is he who can most often act as a carrier of the fungus.

How to kill a fungus.

Due to the fact that many summer residents try to decorate their summer cottage with the help of conifers, and they most often become carriers of this fungus, then the infection of apple trees can occur faster. The thing is that rust pathogens most often live on conifers and shrubs. It is for this reason that you should not plant an apple tree with such crops. Colonies of the fungus begin their formation precisely inside the skeletal branches of the juniper. The shoots become larger, deformation occurs along the entire length. If the infection affects the plant for a long period of time, then it begins to dry out and die. It is important to keep in mind that the fungus itself does not live on the apple tree. A great danger is fraught with spores of the fungus, which can be spread by other insects or by wind. If a juniper still grows near the apple tree, then as soon as you notice the presence of rusty spots on the apple tree, it is necessary to inspect the juniper. If you find a pest on it, then it is necessary to cut and burn the infected parts of the plant and carry out the treatment with fungicides. If the juniper has already received a high degree of infection, then it must be removed from the site, the soil must be well dug up, treated with boiling water and antimicrobial drugs. If you take proper care of your juniper, you will be able to avoid infection. There are supporters of the idea that if you grow fruit crops on your site, then coniferous crops should not be on this site. It is important to understand that fungal spores can be carried over long distances by wind. Therefore, even if you do not have a juniper on the site, it is unlikely to save the situation that has happened. A good option can be the creation of planting barriers from conifers using tall trees with a large and dense crown.

We destroy spores and the consequences of infection.

To prevent rust from returning to your site, it is necessary to take a number of measures aimed at destroying the pest spores. To do this, you need to spray with antimicrobial drugs. You should always keep the area clean so that there are no weeds. Many weeds can act as intermediaries where the pest can feel good. Rust can be negatively affected by proximity to bitter wormwood.If you leave various types of plant debris on the site, then rust spores can live on your site for 8 years. Those leaves of the apple tree that have been damaged, as well as the affected juniper needles and cut branches must be removed from the site and burned. The trunk circle must be deeply dug, add urea (5-7%), ammonium nitrate (5-7%), copper sulfate (4-5%). The drugs must be constantly alternated so that there is no addiction.

Preparations for treating apple leaves from rust.

In order to carry out the treatment of apple leaves against rust, various means are used. Let's consider them in more detail.

Preparations containing copper.

It is good to use Bordeaux liquid (1%) against rust. It is advisable to carry out processing in the spring, when a positive temperature has already been established. processing should not be done when the weather is very hot. Otherwise, trees may appear burns... The following drugs can be used:

Blue Bordeaux. It is analogous to Bordeaux liquid, available in granular form. It dissolves well in water. Causes damage to the entire pest colony, and also destroys spores. Treat infected crops well during inclement weather.

Abika peak. A drug that contains copper. Does not penetrate into the wood. It contains an adhesive. It can only be treated with the product during dry weather. In order to prepare the solution, it is necessary to dissolve 50 g of the product in 1 bucket of water.

Cuproxat... It is based on copper acetate and contains nitrogen. 0.25% solution is good at killing fungal spores. Can be used for root watering. Contains the properties of fungicides and mineral fertilizers.

Champion... More suitable as a preventive measure. The drug acts as a protective film that prevents the spread of infection.

The remedy stops the development of the disease, but does not deal with the destruction of spores. In a bucket of water, you need to dilute 60 g of the drug. If the air temperature exceeds 25 degrees, then processing is not worth it. Funds based on sulfur.

It is good to use colloidal sulfur to kill spores. It is necessary to dilute 40 g of the drug in 5 liters of water. When the tree begins to bloom, processing cannot be done. Cumulus has proven itself well - it is a kind of colloidal sulfur in a convenient form. The product is not dusty and can dissolve well in water.

Application of fungicides.

The use of contact and systemic contact fungicides has proven itself well. The following drugs are very popular: Vectra (2-3 g per bucket of water), strobe (2-3 g), poliram (1.5-2.5 g), topaz (2 ml), zineba (40 g). The drugs have the same effect, but differ in the active ingredients. It is for this reason that it is better to use different drugs each time to avoid addiction. If you properly care for your trees, conduct frequent inspections, fertilize and carry out preventive treatments, this can save your trees from various diseases and viruses.

Also, the leaves of the trees will not be able to get infected with rust, which means you will not need to think about what to do to get rid of it.
