Productivity gives high. The taste of the berries is harmonious. The sugar content of the berries is in the area of 18-21%, the acidity at the level of 6-8 g / l. The percentage of fruitful shoots of this variety is up to 60%, with a bearing ratio of 1.0-1.3. The load on the bush is about 35-45 eyes.

Diseases and pests
Variety Pervozvanny, as it was written above, has good resistance to mildew, oidium and gray rot. But this does not negate the fact that the grower does not have to protect the grapes. Such misfortunes as anthracnose, bacteriosis, chlorosis, rubella or bacterial cancer often become guests of vineyards.
Allocate biological and chemical preparations.. Biological types such as Trichodermine, Gaupsin, Actophyte are quite effective, but their use is rather expensive. Chemicals act longer, but they also cause more harm.
Chemicals should not be higher than the 2nd hazard class.
Most often, the fight against insects and diseases begins in the flowering phase of the vines. Then the eradication treatment with 3% solution of ferrous sulfate is carried out. For the control of fungal pathogens (mildew, oidium, gray mold), fungicides of systemic or contact action are used.
To the system can be attributed Topaz, Kvadris, By-leton - they are used for prevention.
Contact use when the disease occurs. First you need to remove the affected area, and then treat the bush drug.
To do this, suitable tools such as Rovral, Blue-Bordeaux (Bordeaux fluid).
To fight thrips, felt mites, leafworms, the drugs Aktara, Decis-Profi, BI-58 are suitable. It is important to understand that the use of these drugs is possible before flowering and as a preventive measure. It is necessary to apply these means preferably in a sunny, calm weather, while not forgetting about the means of protection.
In addition to traditional diseases that affect the grapes, the grower has two enemies: wasps and birds. Among the insects can be distinguished wasps. They are very fond of sugar, and where, if not in the vineyard, they can be found.
Wasps are not as dangerous as other insects - they do not destroy the bushes, but cause serious damage to the berries. Most often, they eat up the pulp and try to drink the juice from the berries. Sometimes, having spoiled one berry, they gently pierce the others so that fermentation would begin in them. A few days later they return for this "bodyag".
Methods of dealing with them may be different. More often winegrowers resorted to the physical destruction of wasps. One of the most effective ways is to destroy the hive. If he is not found, then baits are placed next to the vines.
Before the grapes bloom, the wasps are fattening protein foods. Therefore, experienced growers are advised to hang on pieces the pieces of fish or meat that were previously soaked in Imidacloprid. When the grapes begin to bloom, the wasps can be distracted from it with the help of traps with a sweet solution. You can add honey or sugar, as well as drugs Aktara or Regent.
Drugs can be replaced with a solution of boric acid. Here we must remember that the wasps do not fall under the water. Therefore, it is better to add a little liquid soap to the solution. There are more humane ways. Ripening clusters can be wrapped in tulle or agrofiber bags.
Protective screen protect berries from wasps. In this case, bags of gauze is better not to sew, because, soaking wet, it sticks to the berries. Best suited bags of caprone. From birds as a protection can serve as a grid along the bushes or a ratchet, which will scare the feathered invaders with a sound.
The Pervozvanny grape variety can grow well in the southern outskirts of Russia. It blooms quickly, gives a weighty harvest. It has good resistance to "grape" diseases, but, like any other grapes, requires careful care.
