The best drugs

There are a number of drugs that need to be treated with apples, just like pears. Let's consider each of them in more detail.

Urea or carbamide is quite common among gardeners. Spraying it helps to effectively control aphids and other pests that 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 foliar. Having a high nitrogen content, it serves to help weakened crops so that they can grow a lush crown and subsequently please the owner of the garden with a rich harvest.

In the fall, urea is sprayed after at least 60% of all the 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 the wood.

Copper sulfate is good for both pest control and prophylaxis against diseases such as anthracnose, moniliosis, scab. It is customary to spray it in order to prevent the appearance of fungi. Since vitriol is quite aggressive, some gardeners do not use it in the fall. Do not spray the solution if the ambient temperature is over + 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 with an element that is very important for their full development - iron.

Autumn spraying makes it possible to destroy such ailments as black cancer, cytosporosis, moss, scab, 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. Apple or pear trees 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 the prevention of such dangerous diseases as scab, powdery mildew, and the appearance of spider mites. Before use, the drug should be diluted in a small amount of water. Then the finished suspension is poured into the main liquid, which is inside the cartridge. Colloidal sulfur is effective only in warm weather.

Dolomite has a deoxidizing property 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 apples and pears, a bacterial pest control agent called entobacterin is also used. It can be used even during the flowering period, since 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 by yourself after combining copper sulfate and lime. This is done at the rate of 100 grams of ingredients per 10 liters of water. It is also possible to purchase a ready-made product that is recommended to be used to eliminate scab, anthracnose and fruit rot.

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

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

Diesel oil should be used carefully so that your favorite apple trees or pears do not get a serious burn after such a drug. It is important to apply this oil before the leaves and buds form. Naturally, you cannot use it during the flowering period. In the fall, be sure to wait for all the foliage to fly from the trees.

The spraying procedure directly depends on what ailment the tree was affected by 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.

Work technology

Before spraying, you need to prepare a sprayer and protect yourself with a mask, glasses, gloves. It is not recommended to use improvised devices, since the fungicide dissolved in water should get onto the crown. It is easiest to apply funds to a columnar apple tree. You only need to go around it in a circle. In order not to provoke burns, it is unacceptable to use a solution that is too concentrated. A simple test is advised before use. To do this, the product is applied to only one branch and the result is monitored after 3 days. If damaged, it will have to be removed, but the whole tree will remain intact. A young apple tree with a 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 finishing spraying, be sure to wash and rinse your mouth, wash your hands thoroughly.

You can hang the chart with the timing of spraying in the shed or other area to check with it from time to time. During work, the tip of the device 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.
