Plum: diseases and pests. How to deal with them?

One of the most dangerous and common plum diseases is sharks. When it appears on the leaves are visible light green rings and spots, and on the fruits - gum apertures and dimples. In case of damage, the fruits fall to the ground before harvest time in two to three weeks. Plums, diseases and pests on which often carry aphids, in this case, can also be affected by leafhoppers. Also, the cause of the disease can be vaccination or planting of already diseased trees. Fighting with shark can only be done by digging out a sick plum, and it should also be carefully examined during transplantation, as an alternative it is possible to get rid of vectors of the disease by conventional methods, for example spraying with special preparations.

Plums, diseases and pests on which often appear when young leaves appear, can be infected with a fungus that causes a burn of leaves. He hibernates in fallen leaves, and in spring moves to a young one. The disease manifests itself after 30-45 days in the form of light yellow spots, which eventually acquire a red tint. At the same time, blisters appear on the lower part of the leaves. If the disease progresses very strongly, then it is possible that the foliage falls off.

The disease called "pockets" causes severe damage to the fruit, the ovary falls off. It also negatively affects shoots and leaves. The cause of this disease is also a fungus. He winters between the scales of the kidneys. How to treat the plum from pests in this case? Excellent Bordeaux liquid 1%. Before processing the tree, it is necessary to collect the affected leaves and burn, only after that sprinkle it.

Plums, diseases and pests on which the most diverse appear, are sometimes affected by viruses. These include a narrow-line and deforming variegation, and any other form of it can be formed. Also, sometimes there is the appearance of fruit rot, root swelling (bacterial cancer), apoplexy, verticilia wilt, chlorosis, bacteriosis. In the case of prolonged atmospheric drought, fruits may fall off. Before that, they acquire a blue color, near the stalk, the skin becomes wrinkled.

Not only the above ailments can be drained. Diseases and pests that interfere with normal growth and development of the tree are not only viruses and fungi. Sufficiently often plum is exposed to aphids (small plum, thistle, hop, etc.), scales (mulberry, red and yellow oyster, acacia false-ticks), mites (plum gallic, red apple, spidera, etc.). You can get rid of these pests on the tree just like on other plants.

The most common diseases and plum pests (a photo of some are given in the article) include such a parasite as a plum gallic fly. Its larvae hibernate in the earth. In the spring of them appear insects, which lay eggs near the central vein. They feed on the top of the leaves. Their larvae leave in June, burrowing into the ground at the same time.

Plum weevil also causes serious harm to the tree. This beetle is bronze in color with a red-copper sheen winters in the soil. In the spring, he eats a young ovary, while the infected fruit falls. All the carrion must be collected and destroyed (for example, burned).

Widely known and such a parasite, as a plum sawfly, which winters in the soil as a false-caterpillar. Adult insects appear before the flowering plum, the females lay eggs in the flower cups, later the larvae bite into the ovaries, while eating the seed.

To combat pests, remove the old bark, and spray the plant several times (usually 4-5). You also need to collect and destroy the carrion. You can use such a measure of struggle, as winter spraying plants with poisonous chemicals.
