Processing of grapes in autumn from diseases. Than to process grape in the autumn?

Like any other cultural plant, autumn grapes should be carefully prepared for winter cold. In addition to additional fertilizing, the last waterings and propoloks, the vine should be treated from various kinds of pests. About how to perform this operation correctly, and talk later in the article.

Classification of preparations used for processing grapes

With what and how the processing of grapes in the fall from diseases, try to understand a little later. First let's see what kind of preparations can be used to treat vines, and in what cases. There are many such means. However, all of them can be classified into several main groups:

  • Insecticides. Used to control pests such as aphids, butterflies, caterpillars, beetles.
  • Acaricides. Used to kill ticks.
  • Fungicides. Used to combat infectious diseases, as well as for their prevention.

Preventive treatment

Processing of grapes in autumn from diseases allows to rid this plant of many problems in the next season. Even in the event that the vine is healthy, preventive spraying is worthwhile. One of the most popular means of preventing infectious diseases of cultivated plants is fungicide copper sulfate. It is his solution (usually one-percent) and the grapes are processed in autumn. Sometimes plants are sprinkled with Bordeaux liquid. This is the same solution of copper sulfate, but in lime milk (75 g of lime per 1% of vitriol).

Treating grapes from oedium

Treatment of grapes in autumn from diseases is an activity that is necessary not only for prevention purposes, but also if the vines have suffered from fungal or viral diseases in a warm period of time. For example, during this period, you can treat plants from an infection such as oidium. This unpleasant and dangerous disease affects all the green parts of the vine. Infection usually develops in summer, in dry and hot weather. The main signs of oidium are white mealy deposits on the inflorescences. After some time the affected parts of the plant begin to dry and fall off. The available berries crack. From the plant it is unpleasant to smell rotten fish.

What to do with grapes in the fall to save him from this scourge? It hibernates the fungus that causes the oidium, under the scales of the vine buds. In order to prevent the repeated development of the disease in the spring, it is worthwhile to spray the plants with the same copper sulfate. Make the treatment best before hiding the grapes. In doing so, use a 4-5% aqueous solution. Spraying is carried out, trying to distribute the liquid on the planting evenly. Instead of copper it is possible to take less poisonous and dangerous iron vitriol. Autumn spraying against the oidium is sometimes carried out with a 3% solution of netrophen.

Method of preparing an aqueous solution of copper sulfate

To make a 1% solution of copper sulfate, you need to dilute 100 gr in 10 liters of water. Of this substance. If you need 4% - respectively 400 gr. Do not pour the powder into the bucket immediately. First pour warm water in a half-liter jar. Pour the vitriol there and stir well. Pour the resulting solution into a bucket. Stirring constantly, add water until it is full.

How to work with a solution of copper sulfate?

So, we have found out what the processing of grapes should be conducted in the fall from diseases. Now let's see how this should be done correctly. Copper vitriol, as already mentioned - the substance is poisonous and for the human body is very harmful. Therefore, they can spray plants only by taking some measures of personal safety. Work in rubber gloves and spray the mixture only in the direction of the wind.

As a result of improper processing, plants can suffer. To avoid burns on the branches, spraying should be done in cool weather. Sometimes in the autumn in the afternoon the air warms up to rather high temperatures. In this case, treatment should be done in the morning or in the evening, or wait a few days before the temperature drops.

Than to process grape in the autumn still?

Since in September the air in the street is much colder than the warmed-up land, the vines begin to drain nutrients from the ground to the roots. This can be seen even in reducing the sugar content in berries. This natural process is worth using in order to feed the plants. To do this, they are treated with potassium solution 2-3 times in September. You can apply a crystal or potassium sulfate in an amount of 20 grams. For 10 liters of water.

Feeding of grapes in autumn

Fructification rather strongly weakens the grapes. If you do not take certain measures, the plants will not tolerate frosts and the next year they will not give a good harvest. One way to strengthen the grapes are fertilizing and mulching. It is best to fertilize the grapes in the fall with well-dispersed manure or compost. Too deep feeding is not necessary. You can even simply muck up the soil around the trunks.

Grapes in autumn should be fed only after all the foliage has been removed from under it. The fact is that it can be wintered by a huge number of various pests. The foliage needs to be piled up and burned.

What else needs to be done in the fall?

Among other things, the preparation of grapes for wintering should include such an event as pruning. From the vine, it is necessary to remove the weakening old, sick and damaged shoots. Too much cropping is not necessary. In particular, this applies to grapes growing in regions with a harsh climate. In this case on the vines it is necessary to leave the so-called "reserve" shoots. If the variety is not frost-hardy, grapes should also be covered with lapnik. For insulation, you can use straw. Sometimes the grapes are covered with polyethylene film or roofing paper. In the latter case, special supports with a height of no more than 60 cm are arranged in the landing. If the structure is higher, in the winter it can be carried by the wind.

What to do with grapes in the fall yet? Of course, you need to try to protect the vines and from all sorts of rodents. To do this, any poison from mice and rats is left under cover. In the spring, grapes can be opened only when the temperature of the air on the street warms up no less than -5 g. Water, accumulating under a film or roofing material during a thaw or spring melting must be removed.

Features of autumn care for girlish grapes

Very often to decorate hedges, terraces and arbors use an unusually spectacular weaving plant - girlish grapes. In the autumn (the photo below confirms this), this decorative culture looks remarkably spectacular. Bright red leaves of some varieties can become just a chic decoration of the site.

Of course, girlish grapes in autumn, like the usual, needs a certain care. The plant is frost-hardy, and therefore it is not necessary to arrange shelter for it. However, prevention of various kinds of viral and fungal diseases is worthwhile. Since the common and girlish grapes belong to the same family (and consequently, they have the same disease), in autumn this ornamental culture can also be sprinkled with a solution of copper sulfate. This will prevent the development of various pathogenic fungi and viral infections.

So, now you know what to process the grapes in the fall. From pests of the plant can be spared by spraying a solution of copper sulfate. Feeding is done by treating plants with dilute potassium fertilizers. In any case, with properly carried out autumn preparation, the grapes will well winter and the next year probably will yield a good harvest.
