A vial of iodine for disinfection of cuts and abrasions, is in the first aid kit for everyone.
But experienced summer residents know that iodine supplementation can help strengthen the seedlings, accelerate the ripening of fruits, and also fight diseases.
A lot of discoveries were made as a result of an accidental coincidence of circumstances during idle idleness. They say that Newton was really good at helping the apple, and Archimedes would not have shouted his famous “Eureka!” If he had not decided to soak in the bathroom.
According to one of the legends, iodine was invented by a cat. Its owner Bernard Courtois – French chemist and pharmacist – decided to play with a pet. But the cat suddenly jumped on the test tubes, breaking them. The contents of the tubes mixed, rising into the air in the form of a purple vapor and immediately settling. This was iodine.
Although we are accustomed to using it for the disinfection of broken knees or garden cuts, iodine is much more multi functional and can be successfully applied on beds for both plant nutrition and disease control. The main thing is not to exceed the dosage and remember that not all plants have iodine for good.
Iodine is necessary for the normal course of a number of biological processes. When applied to the soil, its effect is somewhat reminiscent of the effect of nitrogen fertilizers. In addition, it works as an antiseptic, destroying a number of harmful microorganisms. Iodine can be useful for cabbage, cucumber, tomato, eggplant and strawberry.
Iodine for seedlings
To 3 liters of water add 1 drop of iodine and, carefully mixing, water the seedlings under the root. Top dressing is done no more than once. Iodine helps young plants to get stronger and more successfully to resist illnesses.
Iodine for solanaceous plants
Addition of iodine tomatoes, peppers and eggplants can accelerate the maturation of fruits, as well as prevent the development of late blight. Experienced gardeners recommend to 10 liters of water to add 4 drops of alcohol solution of iodine and pour the tomatoes, adhering to the norm – no more than 2 liters per plant.
Among folk ways to combat phytophthora on potatoes and tomatoes, there is another recipe with iodine. To 10 liters of water add 1 liter of skim milk and 15 drops of iodine. This solution is sprayed with plants no more often than once every two weeks.
Iodine for cucumbers
Iodine can help in the prevention of root rot in cucumbers. For this, 5-10 drops of iodine is dissolved in 10 liters of water and sprayed with the composition of the plant during the formation of buds. But remember, spraying can not be done more often than once in 10 days.
You can also treat plants with a composition of 9 liters of water, 1 liter of low-fat milk and 12 drops of iodine. Spraying can be carried out in May-June every 10 days. This method is recommended by experienced gardeners for combating downy mildew, as well as for preventing yellowing of leaves in cucumbers.
Iodine for cabbage
Cabbage can also be fed with iodine-containing solution (40 drops of iodine per bucket of water). This fertilizer is recommended for seasoners only once a season (at a time when cabbages are just beginning to form). For one plant, you can pour no more than 1 liter of solution (after rain or copious irrigation).
Iodine for strawberry
Iodine can be used to prevent strawberry diseases, but it is also capable of burning its tender leaves. Therefore, when preparing the mortar, do not exceed the dosage in any case. To 10 liters of water, it’s enough to add 5-10 drops of iodine and spray the plants before flowering three times with an interval of 10 days. It is desirable to process strawberry bushes in the evening.
It is important to remember that plants partially accumulate iodine, so in no case should the recommended dosages be exceeded. When spraying it is important to observe safety rules, it is recommended to work in a mask or respirator.
Excess iodine in the human body affects the functioning of the thyroid gland, metabolism, coloring of the skin and is capable of disrupting the internal organs. But in reasonable dosages this medical preparation will be useful to both man and plants. Look in the medicine cabinet. Perhaps your bubble with iodine is just expiring.
