Juniper diseases and their treatment with effective drugs

juniper diseases and their treatment Not everyone knows what juniper diseases are and their treatment. But in order to achieve the desired result and return the plant to an attractive appearance, it is necessary to learn how to recognize diseases and take action at the first symptoms..

Common juniper diseases and their treatment

Growing conifers in a summer cottage, you must be able to provide the necessary assistance when problems are detected.

Fusarium juniper

juniper fusarium The causative agents of the disease are soil fungi that can cause root rot. When it enters the root system, the mycelium blocks the access of nutrients. If nothing is done, then in a short time the upper part of the shoots will begin to fade, turn yellow, and the needles will fall off..

Young twigs are most affected by Fusarium..

The infection persists for a long period of time. Its main place of residence is the soil and affected stems..

A favorable environment for fusarium are:

  • loamy soil;
  • excess moisture;
  • lack of light.

To get rid of this problem, it is necessary to carry out culling in a timely manner. Also, at the first symptoms of the disease, it is recommended to remove the affected plants along with the root system..

As a preventive measure, young plants are treated with Baktofit before planting. They also use a drug called Vitarox. When the first signs of the disease appear, the soil around the plant should be watered with Fitosporin solution. Also, plants are treated with Fundazol..

Drying of shoots

drying of shootsSome types of fungi are causative agents. When they appear, the bark begins to dry out. Brown growths appear on its surface, the branches turn yellow, and the needles crumble. The infection that leads to a similar problem is stored in the affected bark, branches and unharvested shoot debris..

In order to prevent such a problem, it is necessary to use only high-quality planting material. It is also recommended to carry out correct and timely pruning of shoots. In order to prevent the development of infection, all affected areas and sections should be treated with a 1% solution of copper sulfate, and a layer of oil paint should be applied on top.

In early spring and late autumn, the juniper is sprayed with a Bordeaux mixture. If the disease is started, then the procedure is repeated.

Juniper Alternaria

Juniper AlternariaA symptom of the disease is brown needles and a pronounced dark bloom on the shoots. If the disease is not treated with anything, then over time, the branches will begin to fade. The cause of the appearance of Alternaria is the thickening of the plantings..

Alternaria manifests itself only on the lower branches.

The infection persists in the affected areas and unharvested leaves. Fight against Alternaria in the same way as with wilting shoots.

Shute juniper

juniper shuteThis disease has another name – brown gray mold. Its causative agents are fungi that begin to infect shoots at a temperature of + 0.5 ° C..

Schütte only affects plants under snow.

The symptoms of the disease are twigs that have a brown or yellowish tint. The needles also change color and stick together with the help of a grayish spider web.

With the shute, despite the fact that the needles acquire a reddish tint, they do not crumble. But thin twigs dry out pretty quickly. It is they who, first of all, are affected by this disease..

This problem is often caused by high soil moisture, as well as thickening of the plantings. It is possible to prevent the development of the chute by timely pruning of dry shoots. It is also recommended to spray the plant with Bordeaux mixture twice a year..

Juniper rust

juniper rustThis is the most common juniper disease. Mushrooms that lead to this problem sprout on needles, twigs, cones. Such growths have thickening and a bright shade. Bulges and sagging appear on the trunk or at the root collar. Because of them, the bark dries out, and shallow wounds form on the surface..

In early spring, when the snow has not yet melted, growths of a dark brown hue are formed. They are often called teliozha. After rain or heavy fog, they become soft and swell, covered with mucus on top. It is in them that spores are formed that are able to germinate and be carried by the wind..

If you do not take action, the branches dry out rather quickly, the needles change their color to brown and crumble. Infection hibernates on the bark. It can also attack quince and apple trees. Fight rust by removing affected branches. Periodic spraying with Bordeaux mixture is also recommended..

Bark necrosis

bark necrosisYou can determine the disease by the presence of so-called pads, which have a brick-red hue. Growths grow up to 2 mm wide. After a few days, they begin to darken and dry out. Bark necrosis can also affect the root system. The roots are affected and dry out over time. A similar thing is observed with twigs and needles. The infection persists in diseased branches, plant debris. Fight necrosis as well as wilting branches.

Biotorella cancer

biorella cancerThe causative agent of this disease is the fungus biatorella diformik..

Signs of illness:

  1. Drying twigs.
  2. Bark cracking and sores in wood.
  3. The wood turns brown and starts to rot.

Pathogenic microorganisms appear in places where the bark has cracked or received mechanical damage. The fungus develops in the tissues, after which the bark acquires a brown hue and dries up after a while. Such lesions lead to the fact that the needles and twigs begin to turn yellow and dry..

In order to prevent such a problem, it is necessary to follow all the rules and recommendations of agricultural technology. It is also recommended to use high-quality seedlings, because it is they who carry a similar infection..

But, if, nevertheless, signs of a disease appear on the plant, it is necessary to remove the affected shoots as soon as possible. Spray all sections and deformed areas with a weak solution of copper sulfate. Cover the processed branches and trunk with paint or linseed oil. In the first month of spring and October, it is recommended to carry out prophylaxis with Bordeaux mixture. Hom or Abiga-peak can be used instead of this drug..

To do this, annually in May, it is necessary to spray the plant with Fufanon, Aktellik or Decis Profi. If the branches are badly damaged, then all dry shoots are cut and removed, as far as possible from the place where the juniper grows..
