What is late blight and why is it dangerous for tomatoes?
Late blight is a dangerous fungal disease that can lead to the death of the entire crop. This problem is faced not only by novice summer residents, but also by experienced vegetable growers. The disease affects tomatoes growing in open ground and grown in greenhouses.
The course of the disease is rapid.
The main symptom is the appearance of brown spots on the fruits, leaves and stem of the plant .
Most often, late blight appears at the end of summer, when air humidity rises. You can see a wide selection of remedies against the disease on the market, but late blight can quickly adapt to chemicals: experts do not recommend regularly using the same remedy.
Many summer residents have discovered simple folk methods that are just as effective as special chemicals.
What does greenery give to tomatoes?
Zelenka is intended for treating wounds, but its disinfecting properties also help summer residents in the fight for the harvest. One bottle of the product contains 1-2% brilliant green, the remaining 98% comes from ethanol and purified water.
Even in such a small concentration, brilliant green blocks the proliferation of microbes and effectively disinfects plant damage.
Experienced vegetable growers know that this inexpensive pharmaceutical drug copes well with late blight, a dangerous fungal disease of tomatoes. The product also destroys putrefactive and yeast bacteria, scab microbes and pathogens of powdery mildew, olive spot and verdigris.
Zelenka can be used to prevent diseases of tomatoes and cucumbers. It is also used to lubricate cuts on plant stems when planting or pruning branches. You can also use this product to fertilize the soil.
Regular spraying with brilliant green promotes the rapid establishment of plants.
Will it help against late blight?
Zelenka is able to defeat fungal diseases due to the content of copper compounds . It has disinfecting properties and also promotes rapid healing of plant areas damaged by late blight.
The remedy is effective in preventing and treating the disease in the early stages, but in advanced cases, brilliant green is unlikely to help.
The benefits and harms of brilliant green for tomatoes
Reviews show that brilliant green copes well with diseases such as late blight, powdery mildew, basal or root rot, and bacterial cancer. Many of these diseases develop due to a lack of copper in the soil. Zelenka saturates the soil with a useful element.
Important ! Brilliant green solution can be used for spraying, root feeding and pest control. When working with brilliant green, it is important to maintain proportions - increasing the dose will harm the plant.
What are the benefits of brilliant green
Any vegetables require constant care, feeding, and spraying. Zelenka is one of the products that can be used for preventive and medicinal purposes and can be used to replace fertilizers.
Why is a solution of brilliant green so useful? First of all, brilliant green is a wonderful antiseptic that can eliminate infection, kill harmful bacteria, and destroy spores that cause the development of many pathogenic fungi that so often affect cucumbers and tomatoes. In addition, after treatment with brilliant green, plants develop immunity to diseases. They look fuller, greener, and radiate health.
Secondly, brilliant green contains copper compounds and is also rich in microelements, which cucumbers and tomatoes need during growth and fruiting. A solution of brilliant green is irreplaceable on soils containing excess moisture.
When is it necessary to treat tomatoes against late blight?
Many gardeners will agree that it is better to prevent a disease than to try to cure it later.
To prevent late blight, you can use the following measures:
- treat seeds with fungicides before planting;
- Before transplanting seedlings, treat the soil and containers;
- plant plants so that the bushes are well ventilated;
- observe crop rotation on the site;
- After planting, treat the plants.
Attention ! Seedlings, soil and containers can be treated with Fitosporin-M.
You can spray the seedlings with brilliant green as soon as the plant grows 5-10 cm. The second time, the procedure is carried out immediately after transplanting the tomatoes into the ground. As soon as the plants take root, they are re-treated.
The procedure is also carried out at the beginning of flowering. When the first signs of disease appear, damaged plants are removed, and healthy ones are sprayed with a solution of brilliant green every two weeks.
Zelenka for spraying onion seedlings
Onion bulbs should be planted in disinfected soil, for which you can use brilliant green. Five days before planting onions, the beds are watered with a solution consisting of 5 liters of water and 35 drops of antiseptic. Bulbs planted in soil disinfected in this way will not rot and will quickly germinate.
In order for the onion feathers to be green and healthy, when shoots appear, the onions are sprayed with a solution of 5 liters of whey and 35 drops of brilliant green. After 7-10 days, the spraying procedure is repeated.
How to prepare the solution
Recipe No. 1
For 1 liter of water, 1 drop of brilliant green is enough. Treatment can be carried out every two weeks. This concentration of the drug is suitable for the prevention of diseases.
Recipe No. 2
For 10 liters of water, use 40 drops of brilliant green. The solution is suitable for spraying during plant illness. The procedure is carried out several times a season.
Recipe No. 3
For 10 liters of water, take 40 drops of brilliant green and 10 Trichopolum tablets. The tablets are crushed to a powder and, together with brilliant green, are added to water at room temperature. The solution is suitable for spraying.
Peculiarity . Often, to enhance the effect, brilliant green is combined with milk, whey and kefir.
Application for plants
Brilliant greens are used to feed cucumbers and tomatoes both when grown in open areas and in protected areas. Most often, the reason for poor growth and development of agricultural crops is a lack of nutrients in the soil, which is clearly expressed in a change in the natural color of the vegetative mass and thinning of the stems. Spraying plantings helps strengthen their immunity and overall health.
As a fertilizer
Fertilizing cucumbers and tomatoes with brilliant green is carried out even on fertile soils in a greenhouse or in an open area. Budget fertilizer fully compensates for the deficiency of potassium, copper and fluorine in the soil. By feeding the plantings with such a means at hand, gardeners manage to increase their vitality, productivity and saturate them with useful components that cucumber plantings urgently need during growth and fruiting. It is especially important to feed agricultural plants in soils with excess moisture content.
Disease Control
Depending on the type of disease, appropriate treatment is applied.
Root rot
This disease manifests itself on plantings with frequent changes in temperature conditions. Particularly critical for agricultural crops is a temperature drop of less than 16 degrees and an increase to 28 degrees. The development of root rot can be triggered by the use of cold water for irrigation and an excess of moisture in the soil when there is oxygen starvation of the root mass. A root that has undergone putrefactive processes becomes a site for the spread of infection. First, the root part of the shoot becomes thinner, darkens, and then the entire root system is damaged. During the hot season, the lower leaves wither. If appropriate measures are not taken, most of the plantings will die.
To prepare a solution for root rot, you need to measure 1 part brilliant green and 2 parts water. The affected shoot is lubricated with this working fluid, the length of the treated area should be 10-15 cm. To get rid of the disease, two treatments are enough.
Powdery mildew
The disease is determined by the presence of a white coating on the leaf blades, shoots and fruits of cucumbers and tomatoes. The leaves that are closest to the ground are the first to be affected. Afterwards the disease rises up the plant. The crop begins to crack and become moldy. The fight against powdery mildew occurs in several stages, where the first step is to cultivate the land on the site, and then all plantings.
The working solution is prepared from brilliant green (10 ml), water (10 l), urea (50 g), acid whey (milk) 2 l. Apply the recipe with serum against fungal infections. Over the entire season, three treatments of cucumber plantings are carried out with a milk composition: the first - in the flowering phase, the second - after 7 days, the third - after another 7 days. This method treats not only greenhouse plants, but also plants grown in open areas.
Late blight
This disease is classified as dangerous, since in 3-4 days pathogens can dry out the vegetative mass of plants. You need to start processing the stem and leaves as soon as possible in order to save the future harvest. The fungus becomes active at the beginning of summer; spraying should be carried out in hot and dry weather.
To prepare the working solution, use 40 drops of brilliant green per 10 liters of water. Plantings are sprayed every 7 days. Characteristic signs of the disease are dark spots on leaf blades and shoots, wet spots on fruits, and a gray coating.
White rot
Excessive air humidity in greenhouses contributes to the development of the disease. Spores are spread through plantings by the wind. Among the obvious manifestations of white rot are: wilting of the top, white bloom on all parts of the bush, white lumps on them. The disease develops mainly on acidic soils with damage to the root part, leaf blades, and also with sudden changes in temperature. To prevent the appearance of fungus on plantings, it is necessary to calcinate the soil and pre-plant seed treatment.
In the fight against white rot, brilliant green has proven itself very well as a fertilizer. It is effective to use a mixture of it with copper sulfate against fungus. Cucumber lashes are treated with a solution of 10 liters of water and 40 drops of a pharmaceutical product. The number of treatments is 3, the interval between them is 7 days.
Gray rot
The disease begins with the appearance of a fluffy gray coating on plants. Fruits and leaves are primarily affected. The stalk is the first to become infected; fungal spores block the supply of oxygen and nutrients to the fruit, after which the plant withers, begins to rot and dies. Gray rot, in addition to tomatoes and cucumbers, affects berry crops.
To increase the immune strength of plants, prepare a working solution of 10 liters of water and 40 drops of brilliant green. It is used for spraying.
Prevention carried out at an early stage of the growing season will save plantings from fungal infections in the future.
Preparation of the solution
To process tomatoes and cucumbers, use brilliant green or iodine in a ratio of 1:2, where 1 tsp. brilliant green and 2 tsp. water. The root part of the plant is moistened with the solution to a height of 10 cm. And for spraying against fungal infections, a working liquid is prepared from 5 ml of a pharmaceutical product and 10 liters of water. This concentration will not harm plants. For heavily affected plantings, use a solution prepared in a 1:1 ratio; 5-10 drops of the drug are taken per 1 liter of liquid. The effect is enhanced by adding urea.
In addition to brilliant green, summer residents also use ammonia (1 tablespoon of the product is diluted in 10 liters of water), boric acid (2 g per 10 liters of liquid).
Step-by-step processing instructions
Preventive spraying with brilliant green is done before planting seedlings and after the first leaves of the plant appear. 45 drops of brilliant green are dissolved in 10 liters of water, the solution is thoroughly mixed, after which the green mass is thoroughly sprayed with a fine spray bottle.
To disinfect the soil, a bottle of the product is diluted in a bucket of water, then the beds are watered with this solution.
If a disease is detected, you need to remove the damaged leaves of the plant and treat the remaining part with a solution of brilliant green and Trichopolum. The mixture is sprayed with a spray bottle, the procedure is repeated after 10 days. In one season, you can process tomatoes in this way three times.
Zelenka for feeding and spraying strawberries: recipes with video
Garden strawberries are often affected by gray rot and powdery mildew. To treat these diseases, use a composition consisting of a bottle of brilliant green, one liter of milk and a bucket of water (10 l). Strawberry bushes are sprayed in the evening or early in the morning once every 10 days three times. To increase the yield after flowering and during fruiting, strawberries are fed with a solution of 5 ml of brilliant green and 5 liters of water.
In the video clip from the YouTube channel they tell in detail and show how to dilute brilliant green and pour it over strawberries. Watering is carried out after fruiting.

When to process tomatoes and how often
Plants are treated even when there are no external signs of disease development.
Nuances of use in open ground
To get a good harvest, you need to worry in advance about protecting plants from late blight. The best preventative method is soil treatment. You can use copper sulfate or the preparations “Fitosporin-M” and “Arilin”. A proven folk remedy is hot water with potassium permanganate.
Important ! In the fall, you need to thoroughly clean the area of plant debris to prevent the proliferation of dangerous bacteria and fungi.
If tomatoes are grown outdoors, you cannot spray the plants before or after rain - the effectiveness of the procedure is reduced.
In the greenhouse
Treating plants alone will not protect against the spread of late blight. To completely get rid of the disease, it is necessary to treat the greenhouse and garden tools.
To treat the soil in a greenhouse, 50 ml of brilliant green is dissolved in a bucket of water. The procedure is best carried out in the fall after harvesting and removing plants.
FEEDING
Brilliant green solution is a safe fertilizer that has proven itself in horticultural practice; it stimulates the ovaries of vegetable and berry crops, as a result of which their productivity increases. The effect of brilliant green solution on the growth of whiskers in strawberries and garden strawberries is known; it is noticeably reduced. Therefore, berry bushes contribute more nutrients to the formation of ovaries and berries; they grow larger, more aromatic and juicy. Fertilizing cucumbers with greenery is very useful; seedlings take root much better after being transferred to open ground or a greenhouse. Their leaves acquire a rich green color, become strong and dense, a large number of ovaries are formed on the plants, and a bountiful harvest ripens.
Recommendations from experienced summer residents
Simple tips for using brilliant green as a disinfectant will help protect tomatoes from diseases and increase yield:
- When preparing the solution, observe the correct ratio of ingredients;
- the solution should fall on the lower part of the leaves, where the stomata of the plant are located;
- It is better to carry out treatment in the morning or evening;
- do not spray plants in rainy weather;
- Do not allow large drops of solution to remain on the tomato leaves after spraying - this can cause a burn.
How to treat cucumbers with brilliant green and iodine
The method of treating cucumbers is selected according to the type and degree of the disease. It’s better to start with prevention - treating seeds, seedlings, soil for planting, watering and spraying adult plants. At all stages, the dosage and method of processing are selected.
The main rule is not to make a mistake with the concentration of the drug and not to burn the cucumber leaves. We must not forget that plants in a greenhouse are exposed to toxic fumes. Iodine and brilliant green, added to the soil in the required proportions, are a fertilizer for vegetable crops. Treatment methods:
- spraying the wattle with an aqueous solution of iodine or brilliant green - foliar feeding;
- coating the stems with an aqueous solution;
- watering the beds - root feeding;
- soaking seeds in an aqueous solution with iodine or brilliant green before planting.
If you follow the dosage, the frequency of treatments and take preventive measures, most diseases can be avoided, and you will not have to spray vegetable crops with pesticides.
Reviews and results from vegetable growers
Inna, 50 years old: “Zelenka actually helps, but you need to use it from the very beginning of sowing. Later, when the disease is at its peak, it is no longer effective.”
Pavel, 32 years old: “Zelenka is a good folk remedy. It allows you to abandon the use of chemicals, which means the fruits will be environmentally friendly.”
Irina, 65 years old: “There are a lot of remedies against late blight, but I like to use brilliant green. This cheap remedy not only copes with the disease, but also has a good effect on plants and soil.”
Advantages and disadvantages of brilliant green and iodine
There are many different chemical fertilizers and medicines for spraying and watering cucumbers, the use of which gives good results. But almost all of them can settle in the soil or concentrate in fruits, making them less tasty and healthy.
- Using brilliant green and iodine for spraying cucumbers has a number of advantages:
- low price and availability of funds;
- no harm from drugs to humans;
- low consumption of substance when processing cucumber sprouts;
- versatility - with the help of these two antiseptics you can cure a wide variety of diseases and enrich the soil near cucumbers with useful elements;
- the possibility of using these products for processing other vegetable crops grown in the garden;
- the formation of beneficial lactobacilli when using an iodine solution with the addition of milk or whey;
- strengthening the plant's immunity;
- high efficiency of the products when the specified proportions are observed.
The disadvantage of antiseptics is that they contain alcohol and, if overdosed, can cause burns on cucumbers.
Mistakes when using brilliant green
It is better to prevent a disease than to treat it. Therefore, by putting several recipes into practice, regularly using and alternating them when processing tomatoes, you can avoid unpleasant consequences.
Mistakes when spraying
A large concentration of brilliant green in water, instead of being beneficial, can cause damage to tomatoes and lead to burn wounds on the leaves of plants. This is especially true for young seedlings.
Also, the amount of liquid left on the crop can cause burns if too much of it remains on the foliage after treatment. The spray should be like a mist - with a very fine dispersion. For this it is better to use special sprayers.
ENLARGEMENT OF OVERS
The number of berries that will ripen in the garden depends on whether there are many or few ovaries formed on the fruit tree. Every gardener tries to get the most abundant harvest possible, and one of the means to increase the number of ovaries is brilliant green. To grow a lot of cherry and plum fruits, it is very useful to spray the trees after the end of the flowering period with a composition containing brilliant green. You need to dilute 2 tsp. greens in 5 liters of water and irrigate the fruit trees.

FOR CUCUMBERS
A solution of brilliant green is effective for cultivating soil containing a small amount of mineral and organic substances. A lack of soil microelements can cause a wide variety of plant diseases - scab, powdery mildew, gray rot, late blight, etc. It happens that cucumber seedlings develop a dangerous and rapidly developing disease - root rot. The causes of root rot are considered to be high humidity and poor agricultural practices. As a result of the spread of this disease inside the greenhouse, up to 80% of cucumber vines can die.
Cucumbers affected by root rot can be cured by using a solution of brilliant green, alternating with an iodine solution, taking 10 drops of each drug per bucket of water.
Gardeners often encounter damage to cucumber leaves by powdery mildew, a fungal disease that most often appears in early summer. Its cause is microscopic ectoparasites; they infect cucumber leaves, first located near the ground, and then the rest. White drops and spots appear on the surface of the leaves; this is what the mycelium of the fungus looks like. To prepare a medicinal solution, take 10 ml of brilliant green, 50 g of urea and 2 liters of milk. This mixture should be used to treat the soil under the cucumbers after watering.
