Why treat tomatoes with brilliant green and iodine?

Both experienced and novice tomato gardeners know that even the most delicious, productive and unpretentious variety may not please with fruits. It depends on the wrong leaving and adverse conditions, but most often the plants suffer from parasites and bacteria that destroy the crop.

In the fight against pests, many means are used: mechanical removal of insects, traps, feeding, toxic chemicals. But many in pursuit of an effective remedy do not notice simple solutions such as iodine and brilliant green. In this article, you will learn about the treatment of tomatoes with brilliant green and iodine from late blight and diseases.

Norms and proportions

Zelenka and iodine are excellent antiseptics. Despite their effectiveness, there are few people who want to use these drugs internally. Since we are still used to eating the crop, we need to process tomatoes correctly: monitor the dosage and proportions of solutions.

First of all, it is important to know that different processing goals require different dosages. If you are struggling with late blight, then one recipe will do, but for prevention you need a completely different concentration.

The general norm is 45-50 ml of the product per 10 liters of water. If we are talking about the prevention of diseases, and not about the fight against them, then the dosage is different - about 10 ml per 10 liters of water. On the exact proportions and recipes, and how to process tomato, you will find out further.

How to properly handle tomatoes

To figure out how to properly spray tomatoes with brilliant green and iodine, you need to decide on the purpose of processing.

As fertilizer

Iodine and brilliant green are budget fertilizers that increase the yield and vitality of tomatoes. They make up for the deficiency of copper, potassium and fluorine in the soil. Their deficiency in plants can be detected by the following signs: tomatoes become pale, plant stems become thin, and leaves become covered with spots.

The first feeding can be done at the time of planting seedlings in open soil or greenhouse. If you fertilize with iodine, then the proportion will be as follows: 8 drops of iodine per 1 liter of milk. Milk improves the positive effects of iodine and creates a nourishing milk film on the plant. Zelenka should be taken in a proportion of 5 ml per 1 liter of water.

As a preventive measure, it is necessary to spray tomatoes every 1.5-2 weeks with non-concentrated solutions: 5 ml per 10 liters of water - for iodine and 10 ml per 10 liters of water - for brilliant green. Processing in a greenhouse should be carried out less frequently than in an open area so that an excessive concentration of the agent in the soil does not form.

Important! Monitor the soil moisture of the fertilized plants. Too dry soil will be drained even more from brilliant green and iodine, which will lead to drying out of tomatoes, and in too wet soil, preparations will only provoke the appearance of a fungus. Therefore, try to keep soil moisture at an optimal level.

Do not overdo it with the processing of plants, as overdose can cause burns and death of the crop. In addition, try not to stay in the greenhouse for a long time where you treated the plants with iodine: the vapors of this product are harmful to humans.

To fight disease

If it is not about prevention, but about the fight against the disease, then the damaged plant must be lubricated with a solution every day. Iodine or brilliant green is diluted with water in the ratio 1: 2 and grease the stem and leaves daily. The disease usually subside after the first application.

Prevention of late blight

Separately, it should be said about the prevention and control of late blight. Late blight is the most common and fatal disease among tomatoes.

Phytophthora is a frost and heat resistant fungus. Prevention should be started immediately after harvest in the fall. To do this, dilute 50 ml of brilliant green in 10 liters of water and treat the area. These measures will prevent infestation of seedlings in the spring.

To protect the plants directly from late blight will allow timely spraying. In order to prevent it, it is carried out three times.

Plants are sprayed with a solution of 45 ml of brilliant green in 10 liters of water:

1. At the seedling stage.
2. During planting in open ground or greenhouse.
3. After the appearance of new leaves.

Processing is carried out in hot and dry weather, so that the high humidity does not create favorable conditions for the appearance of fungus.

If the above preventive measures did not help and late blight attacked the tomatoes, then the plants are treated with a similar solution every seven days. Also remember to remove diseased leaves and shoots.

Continue disinfecting the soil. how to water tomatoes? Water the area every 3-4 days with a solution of 60-70 ml of brilliant green per 10 liters of water.

Conclusion

The fight against bacteria and viruses is one of the most pressing problems for gardeners. In search of the perfect remedy for infection, people resort to a wide variety of and sometimes dangerous chemicals.

The use of brilliant green and iodine in the processing of tomatoes will avoid harmful effects on both plants and the human body. Remember that everything needs a measure and a reasonable approach, and then these improvised means will help get rid of pests and save your crop.
