Spraying of grapes with iodine solution
По форуму разбросано много сообщений пользователей (включая и мои) об эффективности йода против болячек на винограднике, но поиском по форуму их невозможно обнаружить. Решил открыть отдельную тему, потому что периодически люди спрашивают, как пользоваться и как это работает.

Но смысл текста в том, что молекулярный йод начинает убивать бактерии и грибки уже при концентрации >0.05 parts per million (i.e. 0.05 mg/litre) and at a concentration of 5-10 mg/litre has a rapid (within one hour) broad spectrum disinfectant effect – antibacterial, anti-infective, antiparasitic and partially antiviral. You may ask why the iodine solution is so concentrated? I will answer that with an open wound, it is in your interest to kill all the bacteria in a few seconds – before they penetrate the blood or deep tissues, so you need a “horse dose”.
There are many mechanisms of action of iodine, which explains why in over 2,000 years of using iodine as an antiseptic (think of tying algae to wounds), microorganisms have not developed resistance to iodine. The active form of iodine is precisely molecular iodine and its hypoid oi (-), but not iodide-i (-). The problem with iodine is that it quickly disappears or decomposes into iodides, so iodophores (lugol, foratin) are used to prolong its action. Forum users agree that in the vine such iodophor (and sticking at the same time) milk casein from milk binds iodine and gradually releases it. According to various opinions, such protection lasts for a week to a maximum of 10 days. After the rain, the treatment, of course, should be repeated. My recipe for the mixture is as follows: For prevention – 2 drops of 5% iodine in 50 ml of milk (any), mix thoroughly and bring water to 1 liter. For treatment – 10 drops of 5% iodine per 100 ml of milk per liter of solution.
A drop of iodine is about 0.1 ml, that is, the final concentration of iodine is 10 mg/liter in the first case and 50 mg/liter in the second. It helps against both mildew and oidium. Both sides of the leaf should be treated.
Again, this is a recipe for organic viticulture, when there are 10 bushes on the plot, not for the industrial vineyard, when there is strength and time.

Last year I treated grapes with mildew and Oidium with iodine and soda, because it was too late to use chemicals. The result was very happy. But it was necessary to water the leaf and bunches on all sides. Tended and treated the leaves and bunches superficially. Treated again, but the result is positive. My father started a light vineyard and also treated several times with reinforced cans, the leaves and bunches did not fall off.

How long have you been using this recipe? What are the preliminary results? How have you been processing the grapes? What are your most unstable varieties and how do you respond to them? Sorry to ask so many questions. Thank you so much!
Spraying of grapes with iodine solution
To treat vines and fruits of grapes, use purchased preparations and natural ingredients that do not harm the magic. Iodine and grapes are compatible concepts that do not rule out harvest.
Spraying of grapes with iodine solution
Reasons for using iodine.
Grapes should be treated twice a season. When the first signs of the disease appear, treat the vine and bunches.
For this purpose, food soda, iodine or potassium dressing agents are used. A natural remedy is quickly absorbed by the plant and does not affect the taste. The solution with food effluent is a universal remedy that helps to rejuvenate the plant and increase its defenses.
How iodine is used:
- For disease prevention. The remedy is used to prevent gray rot as one of the most dangerous diseases in the vineyard. The rot affects both fruits and vines, so it destroys the harvest for several years in a row. Spraying is done with diluted iodine.
- During oidium control. Iodine-based preparation helps to end oidium and prevent its further development. The solution is used during the ripening of berries.
- As a complex remedy. A mixture of a solution of boric acid or iodine is used to combat various fungal diseases. The substance is diluted with water and used as a basal top dressing.
An excess of natural substances leads to rapid pre-seeding of the vineyard. Therefore, a precise dosage of the natural component is used in the fight against diseases. In addition, weeds are completely eliminated with the solution. With regular treatment, pests that are contained in the basal layer disappear.
The use of the natural component during the ripening of fruits makes them sugary and delicious.
When to use iodine
Treatment is required when the plant looks bad. If it wilts quickly, the green berries fall off or wilt, the crop’s defense mechanisms should be strengthened. This is done by spraying the trunk, vines and green bunches. Iodine is not only natural, but also a cheap remedy. The preparation is stored for several weeks.
Spraying with iodine is most effective:
- Spring. When the leaves on the vine are covered with brown spots, they are treated. An iodine-based product is used for this purpose. Plaque or dry leaf edges are additional reasons to spray the vineyard. In the spring, plaque can appear on it, which indicates the development of a fungal disease (the leaves have an unpleasant smell).
- Summer. If the bunches, which are still developing, begin to wither in summer, they need to be treated urgently. Natural components allow to get rid of the problem and do not affect the development of bunches. Another reason for additional spraying is if the berries are rotting or cracking.
The choice of a natural product for spraying the plant directly depends on the appearance of the damaged vineyard. Symptoms of the disease determine the choice of the most effective natural component. Iodine is used for both young and mature vines. It leaves no burns on the leaves and strengthens the basic system of the plant.
Benefits of Iodine
the best time to treat is if the berries are larger than a pea, otherwise they may dry out. If the disease progresses quickly, the bunches are treated with a solution of lower concentration. Spraying is carried out with a complex solution. For this purpose, natural serum (1 l) and 1 drop of iodine are used. The treatment is carried out after watering. For prevention, this solution is sprayed once a week at the first symptoms of gray rot – daily for 7 days.” width=”600″ height=”450″ />
Iodine increases the sugar content of berries
Pharmacoid or another type of iodine is a powerful disinfectant that not only protects the plant, but also helps it grow. After spraying grapes with iodine, the following happens:
- The berries are enriched with iodine – when consumed raw, the crop uses an important component for proper thyroid function.
- Sugar utilization in the berries increases;
- The quality of the shell improves, which does not crack even during heavy rains.
Grapes grow faster after processing. If prevention is carried out in the spring, the vineyard will not suffer from diseases of neighboring garden plants. Such measures are suitable for both young vines and adult plants.
Disadvantages of iodine
Natural components have a number of side effects: if the gardener does not comply with the dosage, it will bring harm, not help the vineyard. If there is an excess of iodine, or if the treatment is carried out too often, the root system begins to weaken. The plant gradually wilts (the rhizome does not absorb moisture).
If you treat the culture in the spring (before the formation of bunches) and when symptoms of the disease appear, there will be no problems.
application of iodine
If preventive treatment did not help, then iodine is used to combat the first signs of the disease. To starch the grapes, use a freshly prepared solution. In addition, the vineyard is moistened (spraying the leaves and bunches). The basal part of the plant is temporarily not watered.
Treatment is carried out after sunset (at high temperatures, burns may form on the green part of the plant). Grapes are subjected to additional treatment: remove infected branches and leaves to stop the disease. All tools for pruning the vineyard re-desinfection: When the gardener protects other garden plants from a dangerous disease.
Fighting gray rot.
Gray rot affects grape bunches. If 1 drop of iodine per liter of water is used to prevent FORT, the dosage of the natural component is increased to combat the first signs of the disease.
A good time for treatment is if the berries are larger than a pea, otherwise they can dry out. If the disease progresses quickly, the bunches are treated with a solution of lower concentration. Spraying is carried out with a complex solution. For this purpose, natural serum (1 l) and 1 drop of iodine are used. The treatment is carried out after watering. For prevention, such a solution is sprayed once a week at the first symptoms of gray rot – daily for 7 days.
Mildea control
To combat mildew, a complex solution is used. To prepare it, you will need:
- 1 liter of milk (fresh or sour);
- 20 ml of iodine;
- 10 tablets of trichopol;
- a bucket of water.
It is better to treat the vineyard in several stages: the solution should completely cover all the visible parts of the plant. Iodine with milk spray the culture no more than once every 11 days.
