Necessary

  • - garden tools;
  • - sprayer;
  • - Bordeaux liquid;
  • - the drug "Dnok";
  • - the drug "Quadris";
  • - the drug "Nitrafen";
  • - the drug "Horus".

Instructions

Step 1

When planning the establishment of a new vineyard, when buying varieties, ask about their resistance to diseases that plants in a particular area are susceptible to. Place vines at a sufficient distance when planting.

Step 2

In the spring, with the onset of stable positive temperatures, spray young plantations with the drug "Dnok" or "Nitrafen". In early May, when the shoots have 5 leaves, treat the grapes with 1% Bordeaux liquid or chorus to protect the plant from anthracosis and black spot. In the northern regions, this treatment can be omitted only if the bushes were not affected by diseases in the previous period.

Step 3

Diseases for plants become especially dangerous and destructive during the setting of berries and the formation of flowers. Therefore, while the vine has not entered the time of flowering, spray it with systemic preparations. For even sunlight and airing the bushes, remove excess young shoots.

Step 4

Watch the soil under the bushes: it should always be loosened and free from weeds. After the berries grow to the size of a pea, spray the bushes with systemic preparations again. In stable dry weather, treat the plant with Flint solution. If the weather is constantly humid, spray the grapes with Quadris.

Step 5

The sprayer should have as fine a dispersion as possible, which will prevent the preparations from dripping off the leaves. Treat all leaves on both sides. It is better to conduct this event in the morning after the dew has dried. This will eliminate the occurrence of sunburn.

Step 6

After 15-20 days, spray the vine again with the same set of protective products. Carry out the last processing of early grape varieties in early August. Cut out excess stepsons and shoots so that the bushes do not thicken.

Step 7

In September, if odium appears on the clusters, treat the bushes with colloidal sulfur or manganese solution. Burn all removed leaves and shoots. This will reduce the risk of grape disease. Dig up the ground between the rows.
