Spraying time

Most experienced gardeners know that apple trees, like pears, should be processed in early spring. Care continues on summer days, when pathogens and various pests are most active.

With the arrival of autumn and the moment of harvesting, the processing necessarily continues and is already preventive. There is even a calendar by which you can find out when spring processing should be done and what the goals of it are. It is based on popular observations. The first stage of the work will start in the second decade of March. At this time, new buds are being laid, which is an important moment in the life of both apple trees and pears. It is recommended to study the condition of the tree bark. Pests can hide in it. A special brush will help to remove the affected areas of the bark. It is also advised to apply urea to these places.

In March, it is customary to deal with wintering and inactive pests. After that, already in April, it is necessary to process apple and pear trees again.

The best drugs

There are a number of drugs that need to process apple trees, like pears. Let’s consider each of them in more detail.

Urea or urea is quite common among gardeners. Its spraying helps to effectively control aphids and other pests that have spent the winter in the bark of trees. Spraying is carried out when there is already a steady heat. If you plan to spray only the surface of the bark, you should take a not very concentrated solution. In the summer, urea is also an excellent top dressing. It can be either root or non-root. Having a high nitrogen content, it serves to help weakened crops so that they can grow a lush crown and subsequently please the garden owner with a rich harvest.

In autumn, urea is sprayed after at least 60% of all foliage on the trees has fallen off. Do not rush to use the drug. It is best to do this after the end of sap flow, so as not to reduce the degree of winter hardiness of wood.

Copper sulphate is good both for pest control and for prevention against diseases such as anthracnose, moniliosis, and scab. It is customary to spray it in order to prevent the appearance of fungi. Since vitriol is quite aggressive, some gardeners do not apply it in the fall. Do not spray the solution in the presence of an ambient temperature above + 30 degrees. Otherwise, it will become a real poison for your apple or pear trees.

Iron vitriol serves not only as a remedy for diseases, but also allows you to feed apples and pears, a very important element for their full development – iron. Iron vitriol allows you to stimulate the proper growth of trees and has a beneficial effect on increasing their fruiting. It is recommended to carry out 2 treatments – spring and autumn. Autumn spraying makes it possible to destroy such ailments as black cancer, cytosporosis, moss, scab, and lichen.

Chlorophos has been popular for many years. It is safe for human health and horticultural crops. It tends to evaporate from the surface after 10 days. Apples or pears should be treated with such a preparation when caterpillars of butterflies, fruit mites, aphid colonies and other types of sucking pests have settled on the trees.

Colloidal sulfur acts as a prevention of such dangerous diseases as scab, powdery mildew, and the appearance of spider mites. Before use, dilute the drug in a small amount of water. After that, the finished suspension is poured into the main liquid, which is inside the can. Colloidal sulfur is effective only in the presence of warm weather.

Dolomite has the property of deoxidation, and is also used as an excellent fertilizer with a high calcium content. Spraying is advised to be carried out when the need arises. The best effect is given by such an event held in the spring.

For apple and pear trees, a bacterial pest control called entobacterin is also used. It can be used even during the flowering period, as it does not have a detrimental effect on beneficial insects, in particular bees. The drug has the maximum effect in the presence of high ambient temperatures.

Bordeaux liquid is known to every gardener. It can be easily obtained on your own after combining copper sulfate and lime. This is done at the rate of 100 grams of components per 10 liters of water. It is also possible to purchase a ready-made remedy, which is recommended to be used to eliminate scab, anthracnose and fruit rot.

Ordinary potassium permanganate is considered a good prophylactic against the appearance of fungal infections. It is important to spray it from a plastic bottle.

There is also a soap solution. It is used in spring, summer and autumn. It is advised to combine it with insecticides or mineral supplements. In fact, such a solution acts as an effective organic fertilizer, while simultaneously performing protective functions. In order to repel pests, you can add wormwood, yarrow or coniferous concentrate to the solution.

Diesel fuel should be used carefully so that your favorite apple or pear trees do not get a serious burn after such a preparation. It is important to apply this oil before leaves appear and buds form. Naturally, you can not use it during the flowering period. In autumn, be sure to wait until all the foliage has flown from the trees. The use of diesel fuel is effective, for example, when the apple tree is located at an acute angle and begins to rot over time.

For spraying fruit trees from diseases, a solution of copper sulphate and Bordeaux liquid, which contain a lot of copper, are successfully used in practice. Among the modern effective drugs are Skor, Topaz, Thiovit Jet, Raek, Topsin – M SP, which help to cope with powdery mildew. “Abiga-Peak”, “Albit”, “Alirin-B” will be needed for the treatment of moniliosis and scab.

The spraying procedure directly depends on what disease the tree was affected in previous years, and on the goals of this particular event. For prevention, gardeners prefer to spray with copper-containing preparations until the first buds begin to appear on the trees. Since during the flowering period it will be too late and impossible.

Technology work

Before spraying, you need to prepare the sprayer and protect yourself with a mask, goggles, gloves. It is not recommended to use improvised devices, since the fungicide dissolved in water should get on the crown. It is easiest to apply funds on a columnar apple tree. It will only need to go around the circle. In order not to provoke burns, it is unacceptable to use a solution that is too concentrated. Before use, it is advised to conduct a simple test. To do this, the product is applied to only one branch and look at the result after 3 days. In case of damage, it will have to be removed, but the whole tree will remain intact. A young apple tree with still tender bark is suitable for testing.

The frequency of spraying depends on the needs of the trees and is at the discretion of the gardener. After spraying, be sure to wash and rinse your mouth, wash your hands thoroughly.

You can hang a spray schedule in your shed or other room for reference from time to time. The tip of the device during the work must be kept at a distance of 70 – 75 cm from the tree. In order to evenly distribute the applied composition, the liquid in the tank must be shaken from time to time.
