Summer residents often face the problem when grapes begin to rot while still on the branches.
The problem is a fungal disease that can be treated with a fungicide. But it is much easier to prevent the disease from appearing.
This task can be easily handled by a folk remedy. It is used by experienced winegrowers who do not like to spend money on special preparations.
A soda-based solution can reduce the risk of developing the disease. Take 1 tbsp of sodium bicarbonate per 1 liter of water. Mix the liquid and spray the vineyard with the resulting solution.
When dried, a protective film appears on the vine and leaves, which protects against fungus and repels pests. The solution is completely safe for plants and humans.
The first treatment is carried out before flowering. Then the spraying is repeated from time to time, but not more often than once every 10-14 days. In total, such treatment can be carried out 5 times per season. It is worth choosing cloudy days or spraying the plants in the morning or evening.
