Diseases of the pear

How pleasant it is to look at the blossoming young leaves of fruit trees in spring: pears , apple-trees, plums. And it seems that such fresh greens will please us until the winter. But sometimes the leaves on the trees begin to twist, they form spots, and the flowers wither. If the fruit has already started on the plant, they can begin to rot. What's the matter? It turns out that trees, just like people, can get sick. And pears are no exception. Let's talk about what pear diseases are and how to treat them.

Common pear diseases, their signs and treatment

Very often pears are affected by a dangerous fungal disease - scab . This disease develops particularly strongly in early summer, during periods of high humidity. On the bottom of the leaves of the pear appear spots. At first they are yellowish, similar to oil. Then a greenish-brown coating appears on the leaves, consisting of spores of fungi. If the infection of the scab has occurred early, then the disease from the leaves passes to the developing fruit: they have an irregular, ugly shape. Often they crack. On the fruits appear round gray-black or completely black spots. If the disease has already entered the critical stage, then the entire crop of pears may be lost.

The causative agent of the scab winters in the affected leaves. In spring, on these leaves appear bumps - ascospores. Spores mature and infect young leaves and buds. Especially quickly the spores grow, turning into a mycelium, during periods of heavy rains and warm weather.

As a rule, in order to treat the pear disease of the pear, it is necessary to collect all the fallen leaves in autumn and destroy them, and in spring, spray the trees with Bordeaux liquid.

Another formidable disease that causes great damage to the pear tree is moniliosis or, in other words, fruit rot. Spores of mushrooms hibernate in infected fallen fruit. In spring they are covered with new spores that infect young fruit.

The disease begins in the middle of summer, when the fruits of pears begin to fill. It contributes to this high humidity and high temperatures. The causative agent of the disease penetrates through fissures of the fetus, hailstones or places of friction of the diseased fetus and healthy. A small brown spot appears on the pear. However, increasing, it often covers the entire fetus; it gets dark and soft. Infected fruits fall off, and the fungus that continues to develop in them is transported by wind and insects to other trees.

The disease develops after harvest. Therefore, you need to regularly sort out the fruits stored for storage, and remove the decayed.

Treatment of pear trees from fruit rot is the mandatory collection and subsequent destruction of mummified fruits in autumn or early spring. During the season, the trees are sprayed with a Bordeaux mixture.

Diseases of leaves

By the middle of the summer the pear leaf disease, called the brown spot, appears. This fungal disease is manifested first by small brown spots on the leaves of the pear. Then the spots increase. Most often, the disease occurs against the background of burns from chemicals or pest damage. Treatment is the same as with pear scab.

First, on the leaves of the pear you can see reddish stains, similar to rust, which can increase in size. Then on the lower part of the affected leaves appear outgrowths. These are signs of rust - pear disease, which can lead to a significant weakening of the tree. This fungal disease can develop on juniper, and then spores from it are transferred to fruit trees. Therefore, you can not plant junipers next to the orchard. It is possible to fight rust with sulfur preparations, the same Bordeaux liquid and other fungicides.

A lot of pest pests and her diseases significantly reduce the yield of these tasty and useful fruits. Therefore, you need to work constantly to protect the fruit trees in your garden, and then you will get good harvests.
