Grapes, like most garden crops, are often infected with various diseases, ailments. Therefore, without prevention, processing from pests, viruses and bacteria, you will not get a good harvest, and you can only dream of a large number of prepared wine. In this article, we will consider the most common diseases of the grapes and ways to deal with them.

What is mildeus on grapes, grape leaves: what does the causative agent look like, signs of the disease?

Mildu is called false powdery mildew, it occurs as a result of exposure and getting on green leaves of the spores of mushrooms. The most interesting thing is that the disease came to our country after 1887. It was then that the Americans were brought to Europe for the first time in Europe. Since then, it has spread in all regions of Europe and Asia. It is this disease that causes the death of a large number of grapes.

The disease does not appear immediately, it is quite difficult to notice, because with +8, the spores of mushrooms begin to grow along with the drops of the rain fall on the green leaves and affect them.

Signs:

Initially, on the sheet you can notice light spots, which then become yellow.
Something like an oily spot also appears.
For the entire season of grape growth, several outbreaks of the development of the disease are observed.
It becomes almost invisible at the time when round, green berries appear.
But as they ripen, the skin dries, is covered with a very dense crust. Such berries are not suitable.

What is an oidium on grapes, grape leaves: what does the causative agent look like, signs of the disease?

The Oidium is a disease that, along with Mildu, causes the highest damage to grape plantations and causes the decline of grape industries. The fact is that the disease is caused by a mushroom of real powdery mildew. Infection occurs quickly enough, and most often appears if the bushes are in a poorly ventilated place, there is a lot of moisture in the soil.

Signs:

It looks as if the vine was sprinkled with flour or some kind of ash.
Inflorescences are also covered with some kind of dust, and over time they become a drilling shade.
The ailment also brings a lot of harm to the berries themselves, because when the fungus is spread, the berries burst, the seeds are turned out, a large number of berries do not ripen.
The growth stops at the stage when the size of the berry is not very large.

What is a web and felt tick on grapes, grape leaves: what does the causative agent look like, signs of the disease?

A spider mite also often reduces the amount of grape crop. It affects both leaves, inflorescences, and berries. It is a living organism that is arachnid and arthropod. Outwardly similar to a small spider. It feeds on grape juice, usually sits down from the inside of the sheet, pierces it, sucks the juice.

Signs:

In the places of puncture with a tick, metabolism in the plant is disturbed, brown spots appear and cell division appears, and the disease develops.
You can find a spider and felt tick if you turn the sheet and see. Typically, web -shaped spots appear on the bottom of the sheet.
It is under them that the tick puts down the larvae and grows its offspring. If you do not fight the pest in time, you can lose the crop.
It can also eat inflorescences juice. After piercing the flower, it becomes brown, dies, and as a result you will not get grape hands.

Grape protection against diseases: drugs, complex measures

In order to deal with various diseases of the grapes, it is necessary to adhere to complex measures and prevention. They impede the development and propagation of pathogens.

Stages of processing:

Peace. In general, we can say that this stage lasts almost all winter and spring, until the temperature rises above plus 10 degrees. Double processing of the vine with copper sulfate is carried out. For this, a three percent solution is prepared. The first processing is carried out before shelter for the winter, and the second after you remove the shelter in the spring.
Kidney development. At this time, it is necessary to carry out treatment with drugs BI-58 or Collis. They are effective in relation to tick and oidium. When the kidneys blossomed, it is necessary to process the spotting, insects, as well as parasites that winter in the ground.
The appearance of leaves. When you saw that there were three to five leaves, with the aim of prevention, mildew is carried out, gray rot. For this, fungicides are suitable such as Horus, Delain, Dimilin.
Bloom. Processing is carried out twice before the appearance of the first flowers and 5 days after the grapes foam. At this time, processing is carried out against mildeu, gray rot, as well as ticks. Preparations are used Oktopas, Ridomil Gold, Strobi or Quadris. During this period, processing is also welcomed using mineral fertilizers.
The development of berries. When they saw that the berries became the size of a pea, it is necessary to carry out the treatment with the drug Datan M45. Against Mildu and Oidium, when staining fruits is observed, drugs and fungicides are not used so that the berries are not toxic. During ripening, only such drugs as Fitosporin and Baikal. They are not toxic and are bacteria.
Assembly of berries. After you have harvested, you must prepare the vine for wintering. For this, fungicides are treated. An ideal option would be iron sulfate or fungicides, such as BI-58, Colliewith.

Mildia of grapes: treatment, prevention

Since Mildu develops cyclically, it is necessary to carry out processing in the same way. But if you have no desire to calculate outbreaks of the disease, constantly sit at the vineyard, examining the leaves, then we recommend that processing every 10 days. In addition, there are also preventive measures that prevent the reproduction of the fungus.

Prevention:

It is necessary to mulch the soil
After rain, dry the vine
Drip or drainage watering
You can not fill the plant, water the leaves

Of the drugs, the Bordeaux mixture can be distinguished. Processing is carried out every 10 days. It is necessary to dissolve 100 grams of copper sulfate and the negative lime in a 10 liter bucket of water. The resulting liquid is treated with leaves.

Also, the excess of the irrigation rate is not allowed.

It is worth paying attention to the fact that the oidium is very sensitive to Sere. Therefore, if you find white spots on the leaves, you can process colloidal or crystalline gray. The leaves, the vine, as well as the soil layer are sprayed completely. Because spores of mushrooms can be on the surface of the soil. There are also drugs against the oidium.

Fundazole

Spider mite on grapes: treatment, prevention

In the cold season, that is, in March, it is useless to carry out the processing of gray. Because it will not be very effective. In such conditions, complex drugs, as well as pests against pests, work perfectly.
