What diseases and pests is cedar susceptible to and how to deal with it

Usually, the defeat of the Siberian cedar is extremely rare, the tree has immunity against infections. With age, the plant's endurance decreases, there is a risk of developing fungal diseases, even adverse conditions can harm the tree.

Fungi often settle on the plant, especially with improper care or growing in conditions of high humidity. Insects can also harm the tree and provoke the development of diseases.

Spruce mite

A spruce mite that feeds on the juice of young pine needles poses a considerable danger to cedar. After the work of pests, the needles wrinkle, lose their juicy green tint, and completely dry out. Measures to combat them are regular treatments with Fitoverm.

Folk remedies cannot be used, the tick will endure the treatment and continue to parasitize on cedar needles.

Spider mite

The spread of spider mites in a tree is easy to recognize, the presence of a pest has several signs. The following symptoms indicate the presence of an insect:

• thin web on needles;
• dried needles;
• yellow pine needles.

Fufanon solutions are used against ticks, cook strictly according to the instructions.

Aphid

It is not difficult to identify aphids on a cedar, rather large insects densely occupy branches and needles. What to do to get rid of the pest? Irrigation of the tree with "Karbofos" is recommended. It is better to carry out several treatments with breaks of 10 days.

Small spruce false shield

The pest provokes intense fall of needles, often even small branches begin to crumble. If the necessary measures are not taken in a timely manner, there is a risk of losing the tree.

Insecticide preparations are used to get rid of false shields. Lepidocide treatments are often carried out, especially if the pest colony has already occupied the entire cedar.

Pine Hermes

Hermes larvae densely populate cedar needles and resemble a gray coating.If you look closely at it, tiny insects are easily distinguished. The larvae are unable to harm an adult tree, but young plants can be easily destroyed. To get rid of Hermes, use "Fufanon", "Iskra" (process on needles), it is also recommended to pour plenty of cedar "Aktara".

Pine Owl

You will have to face the scoop in the spring, with the onset of heat, insects actively pounce on the needles, gnaw the branches completely, suck out the contents of the kidneys. In arid regions, the destructive work of the pest leads to the extinction of huge plantations. Usually, the biopreparation "Lepidocid" is used (three times treatment).

Seryanka

The main symptom of the disease is the formation of cedar branches and trunks on the surface. In the spring, aecidia (yellow-gray mass) appears from them. If untreated, the spores in the aecidium rapidly spread through the wood, which leads to a weakening of the tree with subsequent death.

It will not be possible to cope with the disease, the only way to prevent the damage of he althy trees is to remove the diseased cedar.

Moth

Moth moth does not harm conifers, but its larvae are destructive, which in May rapidly begin to feed on pine needles. Caterpillars destroy everything in their path, leaving bare branches (often pests eat even young shoots). It is recommended to use insecticidal agents against the enemy of conifers. One treatment is not enough - to irrigate 3-4 needles.

Rust diseases

When affected by rust diseases, a white coating appears on needles and branches. The lesion usually begins with the kidneys, if untreated, it spreads rapidly throughout the tree. The needles of the cedar pine fall off, the plants begin to dry out. For their treatment, use fungicidal preparations. If possible, make stem injections (introduced under the bark of the conifer).

Pine silkworm shoots

Usually the pest penetrates young shoots, buds. Evidence of the presence of the silkworm is the deformed tips of the branches. Lack of measures will lead to the drying of the cedar.

The control measure is the complete removal of the affected parts of the tree. Be sure to complete the procedure by spraying the cedar "Fastacom".

The next sign of illness is falling needles. If the necessary measures are not taken and the processing is not carried out, the branches will begin to dry out, indicating that wood damage has begun.

Measures to improve tree resilience

Regular treatments and proper care will help prevent cedar diseases. Do preventive irrigation with insecticides at least three times per season. It is better to start in the spring, it is with the onset of stable heat that the pests activate the work.

Follow watering, high soil moisture is detrimental to the tree and helps to reduce immunity. A weakened plant gets sick and is attacked by pests much more often.
