Juniper belongs to the genus of evergreen conifers from the cypress family. A plant can be either a shrub, the height of which reaches 1.5-3 meters, and a tree up to 10-12 meters. They are divided into various subspecies. Like any other plant, a tree can be affected by various infections, viruses, fungi. There are various diseases of junipers that interfere with its normal development.
It is worth noting that the plant is characterized by good resistance to damage by various pests and diseases, unlike the rest of its relatives. The most common diseases of junipers are damage by
rust fungi, which also have a negative effect on other surrounding
fruit trees. Therefore, it is necessary to treat plants as quickly as possible. To do this, double spraying with fungicides should be carried out immediately when the first signs of damage appear. The second process is carried out 15 days after the first.
It is worth noting that coniferous diseases affect primarily weak plants that are deficient in nutrients derived from air and soil. Therefore, it is necessary to use special feeding intended for this type of trees and shrubs. In addition, you can get rid of pests by breeding beneficial insects that destroy them. These include lacewings, ladybugs, buzz flies.
Juniper diseases can also occur due to the defeat of various pathogenic microorganisms that settle on the needles and bark. As a result of such an impact, first a pair of needles become brown, then a whole branch, and then half, or even the whole plant, can go down. Therefore, it is necessary to constantly pay attention to the tree and at the first sign of failure take treatment measures.
Coniferous diseases, which have become common today, are called "shute". Symptoms of this infection are yellowing of needles with subsequent shedding. Initially, the needles of the tree become
reddish-brown in color with transverse black stripes. Gradually, shiny black sporulation points form on them. Further spores affect neighboring branches, as well as other plants.
They also distinguish snow shute, in which the needles acquire a dirty gray color, are covered with a thin mycelium of a gray hue.
It is worth noting that almost all juniper diseases can only be recognized by a competent specialist: how dangerous is the lesion, what is the degree of its development, what measures should be taken, or is it too late to change something, and the plant should be eliminated. Therefore, at the first appearance of any deviations, measures should be taken immediately.
In general, as mentioned above, juniper is rarely sick. And the most common rust damage is more harmful to other plants than to it. Juniper diseases are rare, and the tree will delight the owners with its beautiful appearance for many years.
