Evergreen pine trees delight with their beauty all year round and usually live longer than other conifers. But sometimes these trees are exposed to disease. Pests of pine can significantly shorten their lifespan.
Common ailments
The most common coniferous tree diseases (photos are presented in the article) are fungal. Among them, the most common ailments are fusarium pine (hanging needles and its further redness and drying); ordinary shute (yellowing of needles); brown shute (appearance of mycelium on needles); shyutte snow (gray-ash coating); shyutte gray (mass decay of needles); pine dotystromosis (red spots on needles); rust of pine needles; bubble rust of the trunk; necrosis of the cortex; ulcerative cancer.
Prevention and treatment of Schütte diseases
To avoid such problems, with particular care, select material for planting, timely and efficiently thin out plants that are already rooted. To treat these diseases, it is recommended to spray conifers with various fungicidal solutions (sulfuric or with copper content). Trim the affected branches in a timely manner and remove the fallen needles.
Rust treatment
For their prevention, it is worth isolating diseased trees from healthy ones. Affected plants will have to be completely cut, otherwise infection is inevitable. The treatment is the same as with shute diseases. Soil fertilizer and the use of high-quality immunostimulants are recommended.
Pine pests
Pests of pine do not appear just like that, the mass of their sources. They can come from a neighboring park, where there are conifers, or from the forest, if there is one nearby. In addition, pests can be imported along with soil or purchased along with planting material. The wind, birds, even the person himself can bring harmful insects to the pine.
