Symptoms and treatment of diseases of peach, peach trees

Diseases and pests affect fragrant fruits, leaves and tree trunk. Timely correct treatment can protect plantings and preserve the harvest.

Leaf diseases

There are several of them, all are capable of destroying a peach, plantings need immediate treatment.

Clasterosporium disease (perforated spot) of peach

A fungal disease typical not only for peaches, but for all stone fruit horticultural crops. The fungus affects all parts of the plant: buds, leaves, flowers and ovary, even young shoots. Leaves that are covered with red-brown spots are especially affected. The leaf tissue at this point becomes thinner and dies off. Holes appear on the leaves with a characteristic reddish edging.

Clasterosporium disease (perforated spot) of peach

Lack of processing leads to the spread of the fungus, shoots and even peach fruits are affected.Then red-brown spots are formed on their surface.

Curl

It is also caused by fungus. This is the most common disease that peaches suffer from. Marsupial fungus, the causative agent of the disease, hibernates in cracks in the bark, inside the buds of a fruit tree. In the spring, the disease spreads and affects young buds and leaves.

The leaf tissue swells, acquiring first light green, then reddish, and then brown.

The swellings are covered with a waxy coating, after which the bubbles dry up, the leaves become thicker, turn black. The tree sheds leaves and does not bear fruit. Fruits do not grow, affected leaves curl and fall off prematurely. A tree that has dropped its foliage becomes defenseless and can die with the onset of cold weather.

Coccomycosis

With this fungal disease, very small red dots appear on the leaves, which then merge into large foci. The spores of the fungus are found in gray or pinkish bumps on the back of the leaf. The fungus needs warm, humid weather to spread. Coccomycosis mainly affects weakened trees.

Chlorosis

A disease caused by a decrease in the iron content in the tissues of a garden plant, a violation of photosynthesis, in which the production of chlorophyll decreases. The disease is manifested by premature yellowing of the leaves, while the veins remain green.

Peach curl

The leaves become smaller, curl around the edges, fall off, the root system suffers, in severe cases the tree stops bearing fruit, and young shoots die.

Scab

Disease affecting leaves, fruits and young shoots of peach. Light spots appear on the leaves, they crumble prematurely. When damaged, the fruits are deformed, covered with black crusts. The young bark of the shoots cracks, they stop growing and dry up.

Trunk ailments

The trunk of the peach tree is also susceptible to various diseases.

Gum therapy

Peaches are characterized by gum flow, when a thick dark substance appears on the branches and trunk of stone fruit trees. The process can begin after a frosty winter, as a result of improper pruning, damage by pests (caterpillars and beetles). Sometimes gum flow begins due to excessive watering or the location of plantings on clay soil.

Cytosporosis

It is a fungal infection of the bark of the fruit tree. It dries up, cracks, in a peach the affected area turns yellow, gum begins to stand out. The disease is spreading; if untreated, individual branches or the entire tree completely dry out.

Fetal diseases

Peach fruits are also characterized by diseases in the absence of proper care.

Moniliosis

Gray rot or moniliosis is a disease characteristic of all stone fruits. It is especially dangerous for a peach if its flowering coincided with warm rainy weather. This is a fungal disease, the causative agent of which hibernates in small fallen branches. First, the flowers of the plant are affected, they dry out, but do not fall off, continuing to infect the tree.

Peach Moniliosis

After that, the ovaries and fruits are affected. The resulting small black spot grows, the mold completely affects the fruit. Rotten fruits shrivel, dry up and crumble.

The infection can be carried by garden pests, it is transmitted from the affected fetus to a healthy one, insects often become the cause of moniliosis.

To preserve the harvest, you need to know how to deal with moniliosis. For prevention, the tree is trimmed, before and after flowering, treated with suitable fungicides (Horus, Topaz, Topsin).

Fruit rot

Fungal disease that affects the fetus. It is activated when they acquire a small size (about a walnut). The fruits stop growing, begin to rot and fall off. In a short time, you can lose the entire crop. This is the simplest answer to the question of why peaches rot right on trees.If fruit rot is seen on the tree, the affected fruit is destroyed and the plant is treated with fungicides, sometimes several times, depending on the stage of maturity.

Peach Moniliosis

Powdery mildew

Fungal disease in which first the leaves, and then the young shoots and fruits of the tree are covered with a white bloom. The affected leaves resemble a boat, the fruits begin to crack, from a distance they look like sprinkled with flour. The dots first appear on the seamy side of the leaves. White spots increase in size, then the leaves fall off, the shoots turn black, and the fruits rot and crumble.

What to do to avoid losing your fruit tree? To combat the disease, pruning is carried out, the trunk circles are dug up, and fungicides are sprayed in spring and autumn.

Pests and the fight against them

Aphid

Its invasion begins in early May and may continue until harvest. The pest is easy to spot on the leaves - these are small black, green or white insects. They cover the buds with paddy and, in the absence of protection, form huge colonies on the peach tree in a short period. For protection, the trunk circle is cleared of weeds, dill or other herbs with a spicy aroma are planted around the peach. In case of severe damage, the tree is treated with folk or chemical means.

Flower beetles

A small beetle (about 5 millimeters) with a long proboscis that destroys flowers. They crumble, the tree does not bear fruit. Weevils rise on branches in spring, after the soil warms up to + 10 ° С. When the temperature drops by 3-5 ° C, the beetles fall into a daze. In the early spring morning, you can simply shake them off the tree onto the cloth spread below and burn them.

If necessary, treat the plant with suitable insecticides.

Mites

Ticks are difficult to notice; their appearance is signaled by a cobweb that appears on the tree. Destroyed by spraying trees with infusion of chamomile, tansy, tobacco. In severe cases, insecticides are used. If the plantings are not protected, the leaves affected by the mite dry out, wither, the peach may die, in addition, the pests on the cobweb move to other trees by the wind.

Peach mites

Fruit moth

She eats leaves, buds, even seeds of young peaches. The pest hibernates under the bark. It is activated during budding. The first line of butterflies appears in June. In August, a second wave of the pest is possible.

Eastern moth

A very dangerous pest that can affect most garden trees. Pupae hibernate under the bark; after the temperature rises to + 15 ° C, brown butterflies with wide wings appear. They lay a large number of eggs, of which caterpillars appear in 6-12 days.

The caterpillar very quickly eats the leaves, flowers and fruits of the plant, completely destroying the crop.

Eastern moth

Shield

A harmful insect settles on the bark of a tree. The body covered with a dense shell can reach 7 millimeters. The result of its activity is: wilting of leaves, the appearance of red dots on peaches, loosening of the bark and wilting of young shoots.

The tree is regularly cut, the damaged and old bark is cleaned off, the trunk is whitewashed, capturing the lower, largest, branches. The trunk circle is timely cleared of weeds, fallen leaves, small branches. They dig it deeply, it is useful to sprinkle it with wood ash.
