What kind of grapes is sick
A good harvest is obtained only with a healthy bush, so competent and constant struggle against grape vines are required. Otherwise, unfortunately, it is not necessary to speak about high-quality closes. To combat every disease, there are techniques and funds. It is important to put the correct diagnosis, but will help determine the type of grape disease photos placed before the description of each of them.
Cusar and dangerous mildew fungus
This disease is called still false torment and it is able to destroy the entire harvest if it is not noticed and not to take action on time. Among the existing diseases of grapes - this is the most dangerous. She meets on all vineyards. The fungus does not die in winter, and in the form of a dispute set on the soil and leaves, and in the spring, as soon as the thermometer starts showing +10 degrees with, the disputes come to life and breed. Promotes the spread of false mildew rain and wind.
On the presence of Mildu, yellow stains on the leaves and shoots are indicated. When a wet leaf on the reverse side, as if covered with mold, but there is no dry weather, so there may be doubts about the presence of illness. To make sure that Line is infected with this disease, do this:

The most unpleasant thing is that this dangerous disease is more than others affect the most delicious grapes. If you do not carry out the processing of bushes, as soon as the stains appear, then the fungus goes to shoots, then on inflorescences and ovary. Sometimes, healthy with spring grapes is infected when beautiful bunches are hanging. Berries acquire brown color, become crucified, fall to the ground.
To prevent such a sad phenomenon on its plot, we carry out permanent prevention:
- we remove weeds;
- deeply leaving the soil;
- watch that nothing prevented the ventilation of the bushes;
- we process the leaves with 1% burgundy fluid before flowering, after and when the borders begin to ripe.
We are preparing borodic liquid themselves
The most effective is the freshly prepared burglar mixture. We do it like this:
- we take 2 buckets - 5 and 10 liter;
- i fill at the bottom of the first 100 g of copper mood;
- fill in a bucket with vitriol hot water so that the bucket is complete;
- i smell in the 2nd bucket of 75 g of negated lime;
- add to this bucket cold water - 5 liters, mix;
- focusing the solution if a precipitate was formed;
- we pour into a 10-liter bucket, the contents of a 5-liter container with continuous stirring.
As a result, a blue opaque suspension should be obtained, which and spray plants.
