Diseases of almonds and how to deal with them

Diseases of almonds appear on the plant, if the gardener neglects timely preventive treatments, and also violates the agrotechnology of cultivation and care. Almonds are prone to fungal diseases, often caused by scab, cricosporosis, rust, moniliasis, gray rot and cataract.

Cercosporosis

The disease of fungal nature, which manifests itself in early summer. The first signs of illness - affected leaves, with round red spots with gray patina on top. When the disease develops the leaves turn brown, their fabric dries out and they fall off. Growing new leaves slows down the formation and ripening of fruits and impairs their quality.

Therefore, when the first symptoms of the disease are detected, spraying almond fungicides. Quite good results have shown treatments with the Topsin-M fungicide.

Scab

When the trees are infected with scab, the fruits become unsuitable for consumption, and the development of young shoots slows down. Peddlers of the disease - spores that overwinter in plant debris.

To effectively fight With this ailment, you need to choose varieties of almonds with high resistance to scab. Mandatory processing garden Bordeaux liquid. Almonds are processed in late autumn and spring, after flowering.

Also, careful cleaning of the garden from the windfall, pruning of diseased branches on the plant, and burning of infected parts and fruits are necessary. All this will undoubtedly help in the treatment of the disease.

Rust

The first sign of the disease are small brown specks on the leaves. After a while they increase in diameter and merge with each other. Bottom on the leaves are formed brown pads, after which they fall. They must be removed from the garden and burned.

If this is not done, the pathogens of the disease will remain in the soil and the plant will fall ill again next season. In late autumn, the soil under the almond trees should be dug up, and the plants themselves should be treated with an aqueous colloidal sulfur suspension.

Monilioz

Moniliasis is a fungal disease that is often found on almonds. It can be prevented by prophylactic autumn spraying with Bordeaux mixture. Monilias overwinter in dried, shriveled fruits and on diseased branches.

The spores of the fungus spread in the spring, gradually infecting the entire garden (they are carried by insects and the wind). In rainy summer, the spread of the disease is more rapid and can destroy the entire crop. A dark spot appears on an already ripening almond, which gradually spreads all over the fruit and the almond begins to rot right on the branch.

Klesterosporiosis

The second name for this disease is "perforated spotting." It is characteristic of stone trees and shrubs, and the signs of disease of almond nodules are purple, red-brown and brown spots on the leaves of the plant.

Sometimes they appear on the fruit, gradually becoming larger (a dark brown rim appears at the edges, and the middle of the spot brightens and dries out). Soon, gum begins to appear from the bark of the plant affected by the cholesteroplasty.

Rainy warm summer favors the development of the disease. To list preventive measures The spring processing of almonds by the fungicides "Chorus", "Skor" or "Vectra" is included against the ciliary arrest.The first spraying is carried out before the flowering of almonds, the second - immediately after it. And the third treatment is carried out 14 days after the second.

Gray rot

Botrytis or gray rot appears on the almond dark spots located on the branches and leaves of the plant. In wet weather fluffy gray islands are formed on these parts - fungus spores that are spread by the wind.

A suitable environment for the disease is created by thickened trees, untimely pruning and excessively high doses of nitrogen fertilizers. In the fight against gray mold In the first place winter and spring pruning of trees.

Spring pruning of frozen branches is carried out immediately, after the fall of color from plants, but before the formation of pods with spores of gray rot on the branches. The garden is sprayed with fungicides. The following drugs are suitable for the treatment of the disease: "Topaz", "Kuprosat", "Oxyh".

At the first signs of the disease, the branches infected with fungus are cut out and the garden is treated with one of the above listed preparations. Additionally, you can whitewash (plastering) the stem and branches of the diseased plant with such a solution: 50 g of any fungicide and a pack of wallpaper glue CMC is added to 10 liters of water.

Almond pests and how to control them

Almond Seed Eater

These almond pests have adapted to wintering on fruits that did not fall off the tree in the fall. Typically, these fruits are damaged, which means that it is better to shake off or knock the nuts off the branches and burn them. In mid-October, almond trees are sprayed with special products.

Digging of the soil near the trunk under the winter and burning of fallen leaves and carrion, contributes to the destruction of hibernating insects. In the spring, immediately after the shedding of color, the branches are processed by the Bordeaux mixture (a 1% solution is taken).

Sheet wrench

The caterpillar moths gnaws leaves, further turning them into tubes and laying eggs in them. When such leaf cocoons are visually detected, they must be picked up and burned, thereby destroying the clutch.

To effectively fight with the leafwrap you have to wait until the caterpillars start to appear en masse from the cocoons and can be sprayed with the appropriate insecticides Actellic or Calypso, or they can be treated with similar preparations. Caterpillars are also destructive for treating with 0.3% chlorophos.

In the spring, when the air temperature is above +5 ºC, mandatory preventive treatment of the Bordeaux trees is carried out.

Aphid

Many gardeners in the fight against pests almonds try to do not by chemical means. The nut harvest should not contain residual traces of chemical treatments, therefore, the main ways of combating biologically pure:

• Pepper tincture: 20 pieces of dry hot pepper, pour a liter of water and boil on a small fire for about an hour. This broth is poured into 10 liters of water, stirred and 300 g of gray laundry soap are added. This remedy is infused for 24 hours, until complete swelling and dissolution of soap in water. Plants are sprayed in the morning, after complete drying on the leaves of almond morning dew.
• Tobacco infusion: a glass of pounded tobacco leaves is added to a bucket of water, after which they are mixed and brought to a boil (boil for 15-20 minutes). Insist the decoction for 24 hours. After that, add 50 g of laundry soap to it (for better adhesion), which must be well dissolved and two more buckets of water added to the infusion. After thorough mixing, it will be ready to be sprayed from pests.
• Onion extract: 0.5 kg of onion is taken and minced together with the husk. Then, it is poured with a bucket of water and insist throughout the day. Strain the finished infusion through gauze or strainer - the infusion is ready.

Spider mite

In the dry summer almonds are affected by spider mites. This pest is characterized by rapid reproduction. A colony of spider mites lives on plants in a thin, weightless cobweb and sucks the juice from young leaves and shoots.

The plant weakened by a spider mite easily gets sick, besides the tick itself is a peddler of the disease. Spider mites are destroyed with the help of acaricides, such as Kleschevit, Fitoverm and others.
