Every gardener strive to get a good harvest. But it happens that the fruits start to rot before they ripen on the tree. What are the reasons and how to save the fruits?

Why are pears rotting and cracking on tree branches?

Everyone noticed rotten pears on the tree; the old selectional varieties are mainly subject to such a phenomenon. Since their pedigree is directly related to the wild pear.

Fruit rot - a fungal disease that destroys the crop. If you notice a small spot on the pear, which increases with time, it is rotten. She quickly enough able to cover the entire fruit and harvest.

It so happens that on the skin of all a small speck, and inside the whole pulp is brown and very soft. This suggests the cunning of the fungus, which is ready to destroy not only the appearance, but also the taste.

Fruit rot on apples and pears:

Spores of fungus appear on the infected fruit, on which conidia form. They are carried by wind, rain and insects.

As a result, there is a complete infection of the remaining fruits. The rotting of the pear begins with the tail, and to full maturity the fruit can rot completely.

The cause of rotting pears right on the tree is a fungal disease - fruit rot

The problem must be solved dramatically, that is, will have to remove the old tree.

There is another option save the harvest. Collect pears in immature condition. Large and firm green pears are laid out in the shade, and in a few days you can enjoy fragrant, sweet fruits.

As for the varieties of new breeding, they ripen on the tree. Stored long in a cool place. The cause of decay becomes a fungus.

This disease is called moniliosis. It affects the fetus. The bark of the tree is not striking; it serves as a peddler of the infection.

The fight against the disease is necessary instant. Clean infected pears away from healthy. Do not bury infected fruits with moniliosis in the ground or stored in a compost pit.

Why? This is due to the fact that fungal spores tolerate cold, so they can get in the spring to other trees. A massive defeat threatens the lack of harvest.

Monilioz on fruit trees:

Where the fruit rot is taken from the trees

The fungus moniliosis can get into the fetus through damage to the skin. Damage to the fetus is easy. Insects, hail, rain, wind can do this.

Infection is also possible due to close contact with the infected fungus fruit. Since last year, infected fruits may remain hanging, which spread the infection to a new crop.

Crown of the tree can spread the diseasetherefore, all affected leaves, branches, fruits must be removed during sanitary pruning.

The fungus can get on the pear with the help of insects, hail, rain and wind

Infected fruits, which are not removed after harvest, darken, dry up, and natural mummification occurs. These fruits are desirable to cut along with the branches.on which they hang.

The fungus may be located on the bark of a tree for a long time, with time this place darkens. therefore diseased branches are pruned to capture healthy wood tens of centimeters. All dried shoots pruned to a place with healthy wood.

The disease is tolerated by spores of the fungus by the wind and insects that love to feast on the flesh of a sweet fruit. Favorable conditions for the development of moniliosis is warm and high humidity.

Mostly fruit rot trees are sick with thickened crowns. Therefore, to prevent the occurrence of the disease regularly cut weak branches.

Signs of fruit rot in the trees:

    1. Symptoms of fungus can begin to manifest in the spring.
    1. Infection can occur at the time of ripening. Since during this period the skin becomes softer and spores of fungi can penetrate it. As a result, mold begins to develop, which spreads to the entire fetus.
    1. At the site of infection, fungus sporulation occurs; it looks like it has a round outline with small bright patches in the form of circles. The fungus spreads quickly, affecting not only the skin, but also the flesh.
    1. Infection can occur not only when transferred by insects, but also by close contact of an infected fetus.
    1. Infected fruits fall in strong winds, but they can also hold tight on the stem, they dry out over time and remain hanging on the tree. They harden, that is, mummified and become black and blue. The fungus is not afraid of cold, so it can easily winter through fruits, branches and shoots.
  1. Favorable conditions for the emergence of spores of the fungus is darkness, low temperature and humid air.
Signs of fruit rot are sporulation of the fungus, it looks like it has a round outline with small bright patches in the form of circles.

What if the fetus rots, how to deal with moniliasis?

Caring for future harvests begins in spring. As soon as the snow melts, it is necessary to inspect the tree and the area near it. Collect all last year's foliage and branches, and most importantly the fallen fruit.

If last year's fruits are hanging on the tree, they must be removed.b, as they may be infected with fungal spores. He loves a thick crown and dried branches that do not yield a crop.

Therefore, in order to prevent the monilioz from multiplying, it is necessary to thin the crown, cut off the dried and weak branches.

    1. During the fruiting period the procedure is carried out several times.
  1. Last treatment fungicidal carried out after harvest. To do this, use copper sulphate, which need to be well processed crown, stem of pears and tree trunk.
Be sure to treat the tree as prevention Bordeaux liquid and copper sulfate

At high humidity All pear varieties must be treated with preparations to prevent the spread of the fungus.

It is advisable to use organic fungicides, such as Bordeaux liquid, copper oxychloride. Processing can be carried out during flowering and after it.

Monilioz affects only fruit, but fungal spores can be stored on foliage, crown, and ground. As soon as rotted pears are noticed on the tree, immediately remove them from the branches so that the infection does not spread further.

Collect fallen rotten fruits, as they are also a peddler of the fungus.
