Boric acid 3 percent application for tomatoes. Feeding and spraying tomatoes with boric acid and iodine. Boric acid: harmful properties in case of overdose

Boric acid - crystalline substance colorless and odorless. Available in concentrated solution or powder. Dissolve in warm water before use. Finds its wide application as a top dressing garden plants. It promotes better development and nutrition of plants, increases the flow of sugar, which increases the crop yield several times.

Fertilizer boric acid tomatoes, additionally stimulates the growth of stems and roots, reduces the risk of infection with various diseases.

Beneficial effects of boron on tomatoes

Spraying with boric acid increases the yield of tomatoes.

Using Boron as a plant feed - simple, affordable absolutely every gardener, effective remedy.

It perfectly stimulates the growth of metabolic processes and increases the production of chlorophyll. Under its influence, the synthesis of plant substances is normalized. In addition, a tomato bush treated during the process is much more resistant to changes in weather conditions and resistant to diseases.

Boron deficiency

When a plant lacks Boron, its appearance may indicate this.

With a lack of boron, the stems and leaves of tomatoes become brittle and flowering is delayed.

The leaves of this tomato are small, deformed and pale.
Apical shoots with time die off.
The plant itself blooms poorly, the ovaries form slowly.
In addition, its deficiency provokes other important problems associated with the general well-being of the plant.

Lack of boron affects the fruit set of tomatoes.

Bohr deficiency entails:

the ovary is formed with difficulty, resulting in ugly fruits;
flowering is significantly delayed, the ovary is discarded en masse;
the roots and stems of the plant become brittle and hollow;
leaves of young seedlings may acquire a purple tint;
side shoots begin to grow actively, but soon they dry out;
the growing points of the bush die off;
Chlorosis begins on older leaves.

Boron deficiency can occur in poor, poor soils, wetlands, carbonate alkaline and acidic soils. Medium and light loams have a sufficient level of boron content.

Oversupply

With an excess of the element, tomatoes also cannot develop and grow normally.

In this case, they may experience marginal necrosis. With it, the leaves of the plant begin to turn yellow, dry out and die. The plant gradually withers, which leads to a significant reduction in yield.

Peculiarities

Feeding tomatoes with boric acid is especially important when grown in poor soils.

Boron is an essential element for proper development of tomatoes . But, before using it as a fertilizer, you should familiarize yourself with the effect it has directly on the tomato crop.

Effect of Boron on tomatoes:

influences the formation of the number of ovaries, can accelerate the process of fruit formation;
chemical elements of the plant interact with Boron chemical reaction, which causes the production of more sugar in the fruit. The reaction occurs naturally, which does not raise any doubts about its safety for health. The tomatoes become very sweet and tasty;
under the influence of Boron, nitrogen fertilizers are better absorbed . Almost immediately after treatment, the plant changes and takes on an attractive, healthy appearance;
strengthens the immune system . The plant is practically no more and;
the bush grows better and faster;
if there is excess moisture in the greenhouse, it stops the rotting process.

Foliar boron fertilizing

The introduction of boric acid by spraying guarantees positive result within a few days.

There are 2 ways to apply Boron fertilizing. These are: root - the plant is watered with fertilizer at the root and foliar - spraying.

Event time

For proper plant development, boric foliar feeding carried out several times a season.

Boric acid can be used to soak tomato seeds.

Before planting, the planting material must be soaked for a day in a boron solution at the rate of 0.2 g of powder per 1 liter of water. It is advisable to use water at a temperature of 55 degrees. In this case, the seeds must be placed in gauze or a canvas bag. Water temperature is very important, you need to know that Boric acid powder does not dissolve well in cold water.

Treatment planting material promotes better penetration seeds contain nutrients and beneficial microelements. This treatment allows the seeds to sprout faster and strengthens the immune system.

Treated seeds are resistant to diseases and in the future this will ensure the production of strong seedlings.

Stages

During flowering, tomatoes are treated with boron to obtain more ovaries.

Stages of foliar feeding with Boron:

The period of bud formation.

Active flowering period.

In the initial stage of fruiting.

Root feeding is carried out at the same time as foliar feeding. It is advisable to carry them out together at the same time. Then the plant will be fully provided with nutrients and protected from all sides.

It rarely happens that after the first treatment with Boron, the plant begins to wither; if this happens, subsequent boron fertilizing should be abandoned.

Spraying tomatoes with boric acid for ovary

It is important to spray with a good sprayer so that the solution settles on the leaves in the form of a mist rather than dripping down.

The effect of foliar feeding can be seen already 2–3 days after treating the bushes. Spraying is done using a spray bottle.

You need to spray the entire plant from all sides: leaves, buds, ovary, flowers.

The procedure is in progress strictly in the morning or evening hours . Plants cannot be processed in hot weather. Direct sunlight can cause plant burns.

The fertilizing temperature should be close to the soil temperature.

Proportions boron solution Different ones are used, depending on the purpose of processing.

Working solutions

The concentration of the working solution depends on its purpose.

against ovary fall — Dissolve 1 g of Boric acid in 1 liter of boiling water. After the solution has cooled, you can spray the bushes;

- 1 tsp. Bora is diluted with 10 liters of warm water. For greater efficiency, it is recommended to spray the plant with a solution of potassium permanganate about 7 days before boron treatment. After it, after 7 days, the plant should be treated with iodine solution. Treatment is carried out in mid or late June;

for root treatment The working solution is prepared at the rate of 10 g of Boric acid per 10 liters of water. Since the drug does not dissolve well in powder, it should be dissolved in 1 liter hot water and add it to the remaining 9 liters. If the finished solution is hermetically sealed, it does not lose its beneficial properties within a few days. For spraying, it will be enough to dilute 5 g of the drug in 10 liters of water.

Foliar feeding has its advantages over root feeding. The result of spraying is visible the very next day, while the results of root spraying will be noticeable only after a few days. In addition, significantly less working solution is used when spraying.
Spraying is carried out in the morning or evening hours in dry weather.

Spraying must be done correctly. You must use a good sprayer with fine spray nozzles.

The solution should fall on the plant in the form of a mist, and not in drops. The best effect is achieved by spraying the leaf with back side. Therefore, when processing, the bush should be kept at a much inclined angle so that it can be sprayed efficiently. bottom side leaf.

It is important to consider that an excess of boron is very harmful to tomatoes, so the dosage must be strictly observed.

Experienced gardeners throughout for long years Boric acid was used as fertilizer. Bohr is still considered one of the most effective means in gardening. To properly carry out such fertilizing, you should familiarize yourself with the advice of professionals.

you should make it a rule - When carrying out any fertilizing, the temperature of the water and soil should be approximately the same;

foliar feeding should be carried out at high humidity and air temperature no more 22–25 degrees . At elevated temperatures and low humidity, the solution will simply dry out and there will be no result;

before spraying all plantings, you should try the solution on 1 plant and observe for a while how it reacts to feeding;

the dosage must be strictly according to the instructions, otherwise, in case of an overdose, the plant will receive a severe burn and die. With a small dosage, you may not expect any effect at all;

Boric acid can be used to control pests such as ants.

You should listen to the advice so that when feeding you do not make common mistakes and destroy the plants.

conclusions

The main thing in processing with Boric acid is not to overdo it and prepare solutions in the appropriate proportion. Only when correct use Using the drug, you can get a high-quality tomato harvest.

Before invention modern drugs like Tomaton, amateur tomato experts managed to obtain rich tomato harvests even under unfavorable weather conditions. To do this, they used the most common boric acid, which is sold in any pharmacy for mere pennies. And this simple remedy also helped them in the fight against late blight and other infectious diseases.

How to spray tomatoes with boric acid

To have a lot of tomatoes, you need high-quality pollination. To do this, in the morning, brushes with opened flowers need to be slightly moved (shaken). This is especially important to do in cloudy, damp weather, when normal pollination is very difficult.

Fruit set can also be improved by foliar fertilizing with boric acid.. To prepare it 1 gram of this substance must be diluted in 1 liter of HOT water. A gram of boric acid is a little less than half a teaspoon of the substance. For processing 20 square meters tomato plantings you will need approximately 5 liters of this solution.

Spraying tomatoes with boric acid is most effective in the phase of partial opening of flowers in the second inflorescence. Conduct this operation It is better early in the morning or in the evening, after sunset.

This year, for a full-fledged ovary, I will spray tomato plants with Borogum-M. This drug prevents the fall of the ovaries and the formation of barren flowers. In addition to boron, it contains gum, potassium, phosphorus, nitrogen and a full range of microelements.

For the same purpose, when the first flowers appear and during the development of the first flower cluster, I process the tomatoes (with an interval of 1.5-2 weeks). To prepare the solution, I pour 1 ampoule of the drug into 5 liters of water and generously wet the plant leaves from a garden sprayer. I recommend carrying out the treatment in the evening, after sunset, because active substance Epina is destroyed under the influence of direct sun rays.

Epin can be replaced with any biostimulant that ensures good fruit formation even under relatively unfavorable conditions. Typically, spraying with biological products is carried out at the beginning of flowering of the first, second and third clusters.

Boric acid against late blight

Without preventive measures late blight will quickly conquer your tomato beds

Boric acid is also used to prevent late blight and other infectious diseases . To do this, tomato plants are systematically sprayed or watered with a solution of this drug.

The bushes are treated for the first time 2-3 days before planting. permanent place. For this, 1.5 grams of boric acid powder and 3 grams copper sulfate dissolve in 3 liters of hot water.

Subsequently, tomatoes are sprayed with boric acid every 2 weeks. The solution is prepared as follows. To 10 liters of water add 1 teaspoon of boric acid, several crystals of potassium permanganate and a couple of tablespoons of grated laundry soap. The soap will allow the solution to stay on the tomato leaves longer.

After July 15, it is useful to add 100 grams of finely grated garlic to this solution. Just remember to strain the resulting liquid after stirring.

To prevent late blight from reaching your tomato beds, water them with a solution of boric acid with the addition of iodine. To do this, dilute 2 grams (one sachet) of this substance and 10 drops of iodine in 10 liters of water and water the plants on top directly from a watering can. The first such preventive watering is carried out 10-14 days after planting the seedlings in the garden bed, the second time the plants are irrigated after June 20.

Late blight is the most dangerous of tomato diseases, so it is better to combat it comprehensively. Detailed instructions on protecting tomatoes from this fungal disease you will find in.

» Tomatoes

Care cultivated plants in the garden plot is not limited to planting and harvesting. The main thing is timely watering, protection from diseases and fertilizing plants for growth and increased productivity. Tomatoes, like other crops, are very sensitive to fertilizers and respond abundant flowering, increased ovaries and rich fruiting. One of the unique fertilizers is boric acid. It not only provides tomatoes with such an essential microelement as boron, but also effectively fights late blight of tomatoes when sprayed.

For normal development and optimal fruiting, plants need a lot of useful substances. The uniqueness of boron is that it helps to take from the soil all necessary micro and macroelements.

Boric acid – crystalline powder white, tasteless and odorless, easily soluble in warm water. Boron is included in many ready-made fertilizers, primarily used for seedlings, as it helps improve their nutrition, more complete absorption of nutrient organic and minerals from the soil, thereby creating a good base for the further development of plants.

Vegetables and fruit crops absorb much more boron than, for example, cereals. Therefore, it is successfully used to treat or feed cucumbers, potatoes, beets, strawberries, grapes, pears and apple trees in greenhouses and open ground.

Boric acid is very effective in combating late blight, Besides:

actively affects the flowering of plants, enhancing it;
promotes the formation of ovaries and prevents their shedding;
prevents tomatoes from rotting due to excess moisture;
increases the flow of sugar to fruits and seeds.

For tomatoes, fertilizing with boron is especially useful; it is carried out in two ways:

foliar spraying of the ground part tomatoes with boric acid solution;
watering bushes with solution at the root(for tomatoes and cucumbers).

Spraying has a better effect on tomato plants: it stimulates the growth of the root system and stems, improves metabolic processes, the synthesis of nutrients, and increases the level of chlorophyll. All this makes the plant stronger and more resistant to various diseases.

This feeding is especially useful for tomatoes grown at home - V flower pots or on the balcony, since they are more weakened than their ground relatives, they require increased nutrition.

Spraying with a solution of boric acid can increase the yield of tomatoes and significantly improve taste qualities due to an increase in fruit sugar content.

When to fertilize

During the entire growing season, fertilizing is carried out several times. Even before sowing, the seeds are soaked in a nutrient solution for a day. To do this, 0.2 g of powder must be diluted in 1 liter of very warm water - 50-55 degrees(in cooler water, boric acid powder takes a long time to dissolve and does not completely). The seeds are placed in the solution in a gauze bag so that they do not float to the surface.

This seed treatment significantly increases their germination, strengthens seedlings, promoting a more complete supply of nutrients, protects against diseases even at high humidity.

Subsequent spraying is carried out 3 more times:

during the formation of buds;
during the period of mass flowering;
at the beginning of fruiting stage.

Between feedings there should be minimum ten days. If the plants responded well to the first treatment, it is advisable to carry out subsequent ones, and if not, it is better to refuse and not water with this type of fertilizer.

The prepared spray solution (see recipe below) should be sprayed from a spray bottle directly onto the leaves, stems, buds, flowers and fruits of tomatoes. This kind of feeding much more effective than watering at the root, as it ensures rapid absorption of boron by the plant. The result is noticeable literally on the second or third day after treatment.

Spraying tomatoes must be carried out exclusively in the morning, evening or in cloudy weather to avoid direct sunlight during the treatment period, otherwise the plants will get burned and may dry out.

So simple and cheap way will help you harvest a rich harvest of delicious sweet tomatoes and improve their keeping quality, which is very important for preserving the harvest.

Signs of boron deficiency in tomatoes

By appearance plants can easily determine that they lack boron:

upper (but not lower) leaves of bushes turn yellow, curl, become small, deformed;
apical shoots gradually die off, because nutrients do not enter plants;
tomato bushes bloom very weakly, ovaries do not form, a large number of barren flowers, small ovaries fall off.

Tomato plants must be treated only with a warm solution of boric acid! The water and soil temperatures should be the same.

Useful properties of boric acid for tomatoes

Tomato is one of the most popular fruits in the garden or garden plot. The benefits of boric acid for their nutrition and cultivation can hardly be overestimated. We can say that the future harvest of tomatoes largely depends on boric acid, because it has a positive effect on the entire growing season plants:

strengthens and nourishes seedlings;
activates flowering;
increases the number of ovaries;
prevents fruit rotting;
promotes the transport of sugar along the stems, increasing the sugar content of the fruit.

Instructions for preparing a spray solution

To prepare the solution, you must observe some subtleties and follow the instructions for use and use. Dilute boric acid powder (approximately 0.5 level teaspoon) in a glass of hot water to quickly and completely dissolve it, and then add it to 10 liters of water, stir, and spray the tomatoes with this prepared solution.

Depending on the purpose of processing, different proportions are used:

To prevent the ovaries from shedding, 1 g of boric acid is dissolved in 1 liter of hot water. After the solution has cooled, spray the tomatoes with a spray bottle.
To combat late blight add 1 teaspoon of powder to a bucket of warm water and treat the plants. To achieve better results, it is recommended to spray the tomatoes a week before. weak solution potassium permanganate, and a week after treatment with boron - a weak solution of iodine.

Treating tomato plantings with boric acid is the most effective and cheapest way to obtain a healthy and abundant harvest. The main thing is not to overdo it, strictly observe the proportions, and the excellent result will please you.

Boron is considered one of the most important and necessary microelements for all garden and garden crops, including for tomatoes. Fertilizers containing it will help provide plants with this substance; boric acid is considered the most effective and efficient. When applying, it is necessary to take into account a number of specific features of this fertilizer.

Brief description of the culture

Tomatoes belong to herbaceous vegetable crops from the Solanaceae family. There are both annual and perennial plants.

The stem is erect or lodging, branching. It reaches a height of 30 cm to 2 meters and above. The foliage is dissected into large lobes, imparipinnate. The flowers are yellow, small, collected in inflorescences - brushes. The fruit is a berry weighing from 50 to 500 or more grams, juicy, colored in various shades of red or yellow. The root system is powerful, tap-type, quickly forms and grows. It lies at a depth of up to one meter, spreading in different directions by 1.5-2.5 meters.

The value of boron for tomatoes

Tomatoes experience a severe lack of boron in the first weeks of cultivation, when the formation of roots, flower clusters, buds occurs, flowering occurs and the ovary is formed. The addition of boron during this period stimulates the growth of young roots, due to which young plants take root and take root faster.

Why fertilize tomatoes with boron?

The substance has the following effects on older plants:

stimulates the growth of flower clusters and increases the number of buds in them;
prevents shedding of the ovary;
increases the level of resistance of tomatoes to major fungal diseases ( powdery mildew, leaf spot, late blight);
activates the flow of carbohydrates into fruits, thereby increasing their sugar content;
promotes friendly and abundant flowering;
increases the ability of tomatoes to synthesize and absorb the substances they need;
reduces the risk of rot developing in wet weather;
stimulates rapid ripening of the crop.

Tomatoes need boron in a relatively small amount, but the lack of this microelement immediately negatively affects the condition of the plant. When there is a deficiency of the substance, the following negative changes occur in the culture:

chlorosis develops, which initially appears on old foliage and then affects new foliage;
powerful growth of lateral shoots is activated, which dry out very quickly;
turn brown and black, and subsequently the growth points die off;
petioles and stems become brittle and hollow;
foliage on seedlings and young tomatoes takes on a purple color;
the number of buds decreases;
flowering rate decreases;
the ovary crumbles;
The yield is reduced, the fruits are small and often deformed.

Boron deficiency

Boron deficiency is least noticeable on clay and loamy soils. Typically, boron deficiency is most pronounced in the following types of soil:

sandy soils;
carbonate alkaline soils;
acidic soils after liming;
poor sandy loams;
swampy soils.

Excess boron is no less dangerous for tomatoes than its lack. In this situation, necrosis begins on the lower leaves, they turn yellow and fall off. Subsequently, the damage spreads to the foliage of the middle tier. The plant gradually fades, the yield is significantly reduced.

Excess boron

This microelement is present in various fertilizers, but boric acid is the most common among gardeners and summer residents. Available in the form of borax or powder, in which the boron content is 11.3 and 17.5%, respectively. The substance is most common in gardening and horticulture, since fruit and vegetable crops consume more boron than grains.

Brief description of the drug

Boric acid is found in pure form in nature. Its sources are minerals, hot geysers, and the sassolin mineral.

It is chemically synthesized by mixing borax (sodium tetrabonate) and of hydrochloric acid. Ready product in the form of white, odorless, powdery granules. Upon closer examination, layered small flakes can be found on the surface of boric acid granules.

Additional Information: boric acid is poorly soluble compared to other acids, but a suspension can be obtained in heated water.

Application of boric acid

Fertilizer is used in almost all vegetative phases of tomato growth and development. During pre-sowing treatment of seed material, the substance is used as an antiseptic and growth stimulant. To do this, the seeds are soaked for a day in an aqueous solution of boric acid, after which they are planted in the ground. To prevent the seeds from floating to the surface of the solution during the soaking process, they should be placed in a special gauze bag.

Seeds in a gauze bag

Dry or diluted fertilizer is added to the soil before seedlings are planted there after germination.

In subsequent phases of tomato development, an aqueous solution of boric acid is applied either by the root or foliar method. In the first case, diluted fertilizer is poured directly under the root, and in the second case the leaves are sprayed. The second method is considered more preferable, as the microelement is fully absorbed and immediately becomes available to the plant.

If you apply excess potassium fertilizers, you can reduce them negative impact by unscheduled spraying of plants with boric acid. The fertilizer solution has a stimulating and disinfecting effect, due to which it is also widely used for the prevention of late blight and other diseases. Boric acid is also added in cases where the plant is clearly deficient in the microelement.

Fertilizer timing

Tomato seeds are soaked in boric acid one day before planting in the soil. Pre-sowing application of fertilizer in greenhouses and beds is carried out either a few days before transplanting tomatoes, or directly during the process of planting plants in the ground, thoroughly mixing the fertilizer with the soil. In this case, it is necessary to embed the boron into the lower soil layers, otherwise it can burn the root system and provoke the death of the plant.

Fertilizing tomatoes with boron

Fertilizing using boric acid is usually carried out 2-3 times per season, and if necessary, their quantity is increased. The first procedure is carried out with the aim of better formation of the ovaries during the appearance of buds on the first fruit cluster. Then fertilizing is carried out during mass flowering and fruiting of tomatoes. At the same time, root spraying is also allowed.

Important: During the pollination period of tomatoes, boric acid treatment is not carried out. Instead, it is allowed to add ash to the root area.

Spraying with boric acid against late blight is usually carried out in late May - early June, before the first symptoms of the disease appear. In this case, tomatoes are sprayed no earlier than 2 weeks after planting in open ground. A week before treatment, tomatoes are treated with a weak solution of potassium permanganate, and 7 days after adding boric acid, they are sprayed with iodine.

Fertilizer application in case of boron deficiency is carried out at the first appearance of the main symptom of boron starvation - chlorosis. At least one and a half weeks should pass between two feedings. If after the next treatment the condition of the bushes has noticeably worsened, further use of boric acid should be postponed or completely abandoned.

Preparation of boric acid

Methods for preparing a fertilizer solution vary depending on the current growing season and the purpose of treatment. To prepare the solution, you should first prepare water heated to soil temperature, since boric acid crystals are practically insoluble in cold liquid. It is necessary to strictly observe all proportions, since even a slight violation of them can cause harm to the plant instead of benefit:

when soaking seed material before sowing, dilute half a gram of fertilizer in a liter of water;
to apply to the soil before transplanting seedlings or adding seeds, you need to dilute 2 grams of the substance per 10 liters of water;
to protect plants from late blight, one teaspoon of fertilizer should be dissolved in 10 liters of water;
before treating tomatoes at the root, dilute 10 grams of dry fertilizer in 10 liters of water;
for foliar treatments, it is necessary to dissolve 5 grams of boric acid in 10 liters of water, observing a solution consumption of 1 liter per 10 square meters of area.

Preparation of boric acid

Carrying out treatments

Regardless of the phase and purpose of use for tomatoes, boric acid is sprayed in the mornings or evenings, when there is practically no risk sunburn plants. Tomatoes are processed in dry, windless weather, when no precipitation is expected shortly after the procedure.

Additional Information: If it rains within a few hours after completion of spraying, the treatment must be repeated in good weather, since moisture washes the fertilizer away from the plant.

In some cases, tomatoes are root fertilized with boric acid. The method implies that it is not the plant itself that is treated, but the upper layers of soil between the rows and near the bushes. To do this, use a garden watering can with a special nozzle. The effect of the procedure is not noticeable immediately, but after a certain time, during which the crop receives boron from the soil and absorbs it. This method of spraying tomatoes is appropriate if it is carried out exactly on time and the plants themselves are in acceptable condition.

Spraying tomatoes with boron

When root feeding there is a risk of burns on the roots. To prevent such consequences, it is recommended to pre-water the bushes with water.

Boric acid is more effective for tomatoes during foliar treatment in the greenhouse and in the garden bed. open ground. In this case, boron that gets directly onto the surface of the leaf is absorbed almost instantly. This spraying method is considered optimal in the fight against diseases and for accelerating fruit set in tomatoes.

Important: The effectiveness of foliar spraying also lies in the fact that this method of treatment reduces the consumption of boric acid. This makes it more profitable from an economic point of view. There are 50-100 ml of prepared solution per plant.

For the procedure, use a working sprayer or atomizer equipped with a nozzle with a fine spray mode. Fertilizer should reach the plants in the form of a mist, not massive drops. It is also desirable that the liquid solution of boric acid does not flow from the surface of the leaf onto the soil, but lingers on it.

Fertilizer is absorbed most effectively and quickly through the underside of the leaf blade. In order for it to penetrate this part of the plant, it is necessary to place the nozzle towards the plant from bottom to top and at a slight angle.

Boric acid against ants

Fertilizer can also become an insecticide and destroy a number of pests, including ants. Boron has a negative effect on nervous system insects Having penetrated inside their body, the drug provokes paralysis, which soon leads to the death of the ant.

Boric acid belongs to substances of the 3rd hazard class, which makes it moderately dangerous. Boron has the ability to gradually accumulate in the body and is difficult to remove from it. When working with fertilizer, you must follow the instructions for use and take precautions. You should prepare the following equipment in advance:

latex gloves;
respirator;
apron;
special glasses.

Individual protection when spraying tomatoes

During the preparation of the solution, it is necessary to ensure that there are no pets or small children near the fertilizer. For a child, the lethal dosage is 4 grams of boric acid orally, for an adult – 15 grams.

Other feeding products

Among mineral fertilizers The most suitable for feeding tomatoes are the following:

double and simple superphosphate;
potassium sulfate and chloride;
potassium salt.
From complex fertilizers recommended for use:
Station wagon;
Effecton;
Kemira;
Mortar;
Signor Tomato.

yeast;
humates;
ash;
herbal infusion.

Proper plant care is the key to a rich harvest.

For the normal development of plants, a number of useful substances and microelements are necessary. One of the most important is boron. It promotes the process of synthesis of nitrogenous components and has a positive effect on metabolism, increasing the amount of chlorophyll in the foliage. Experts believe that boric acid is one of the most accessible and simple compounds of this microelement. It is successfully used in complex fertilizers.

The active use of boric acid in the garden has many beneficial effects.

What is this tool? These are colorless, odorless crystals that quickly dissolve in an aqueous environment.

Useful qualities

This product can be used on a variety of soils. Gray and brown forest and soddy-podzolic soils give good results after application. Gardeners also recommend applying this substance to light soils, to black soil. It is mandatory to use boric acid for gardening on acidic, waterlogged or dark-colored soils.

This product perfectly helps to increase the number of ovaries and significantly increases productivity. After using boric acid for a vegetable garden or garden, it actively develops root system and the stem of the plant. The amount of sugar increases, the taste of the fruit improves.

Boron is a “fixed” element in plants. It cannot change from old withering leaves to young ones. Therefore, it is necessary for plants throughout the growing season.

Experts know that everything horticultural crops V different quantities need boron. We will conditionally divide all of them into 3 groups of needs:

small (strawberries, potatoes, legumes);
medium (tomatoes, carrots, stone fruits);
high ( fruit trees, beets, cabbage, rutabaga).

Although potatoes and strawberries are classified as having a low requirement for this microelement, its deficiency can negatively affect these crops.

Signs of boron deficiency in plants

Not only acidic soils, but also soils with high humidity. The lack of this substance affects plants in different ways. Corn and potatoes require virtually no additional application. But if this microelement is not enough, then the potato leaves begin to turn yellow, the tubers do not develop, and cracks appear on their surface.

A lack of boron in plants can also lead to the development of diseases - brown and dry rot, baketriosis, and blight. The following signs indicate a lack of this microelement in the soil:

the buds dry out;
plant stems become crooked;
growing points die off;
plant leaves become curly and pale;
no flowering.

These signs are especially pronounced during dry seasons. Many amateur gardeners, when harvesting a small harvest, blame it on the lack of moisture, and not on the lack of essential microelements in the soil.

Methods of use in the garden and in the garden

The benefits of boric acid are invaluable and quite varied. But you should be careful with this element, because an excess can harm the plant, accumulating in the fruits, like other fertilizers. Therefore, before you get a positive effect from using boric acid for your garden or vegetable garden, you should pay attention to the advice of experienced gardeners. The main task is to comply with the dosage and use the drug correctly.

Consider these methods of using boric acid:

stimulation of seed germination;
preparing the soil for planting;
foliar planting;
root feeding.

Boric acid is actively used to stimulate seed germination. How to dilute this product correctly? It is necessary to take 0.2 g of powdered product per 1 liter of water. The crystals dissolve quickly. Seeds are soaked in this solution:

onions, carrots, beets - for 24 hours;
cucumbers, cabbage, zucchini - for 12 hours.

How to dilute boric acid for sowing or planting? Everything is the same: in proportion to 1 liter of water - 0.2 g of product. Planting beds should be watered with this solution. Consumption: 10 l per 10 m 2. Then the soil should be loosened and then the seeds should be planted. This method is used if there is a suspicion of a deficiency of this microelement in the soil.

Boric acid is very important. Solution concentration: per 1 liter of water - 0.1 g of boric acid. The first spraying is carried out at the stage of bud formation, the second - at the flowering stage, the third - at the fruiting stage. Sometimes other drugs with boric acid are used together. For spraying in this case, take a smaller dose (5-6 g per 10 liters of water).

Foliar fertilizing with boric acid must be carried out in cloudy weather. Experienced gardeners always postpone this procedure until the evening to avoid sunburn. If it is necessary to spray on hot days, you should first water the plant.

Fertilizing with boric acid at the root is rarely used. In this case, you should make sure that the soil really lacks this element. Most often this procedure is used for seedlings flower plants, which grow on a mixture of peat and sand or soddy-podzolic soils. The solution is prepared using 0.1-0.2 g of the drug per 1 liter of water. But first, water the plant generously with plain water to avoid chemical burns.

Remember that boric acid dissolves well in hot water. First of all, you need to dissolve 1 sachet of the drug in 1 liter of hot water. After this, the solution should be brought to the required volume by mixing with water at room temperature.

Potato processing

The following factors indicate a lack of boron in potatoes:

general developmental delay;
fungal scab disease;
the growth point is inhibited;
leaves turn yellow;
The petioles turn red and become brittle.

Potatoes' need for boron directly depends on the soil, or more precisely, its acidity. This indicator is also affected by temperature and the ratio of minerals contained in the soil. If an amateur summer resident exceeds the norm when applying nitrogen and potassium, then the plant’s need for boron increases significantly. If the dose of phosphorus fertilizer was increased, the need decreases.

If the first signs of scab damage appear on potatoes, it is necessary to use boric acid at a rate of 6 g per 10 liters of water. To prevent this disease, it is necessary to spray potato tubers at the stage of appearance of the first shoots.

Beet processing

Lack of boron in beets provokes the occurrence of wormhole and core rot. Often the cause of such lesions is fungal disease- fomoz. In this case, concentric light brown spots appear on the leaves, in the center of which there are black dots. Afterwards the disease spreads to the root crop. On initial stage When cut, the tissues of the root crop are dark brown in color. Subsequently, the affected parts dry out and become rotten.

Before planting, the seeds should be soaked in a boric acid solution. It is also necessary to add it to the soil to prevent the appearance and development of Phoma.

If the soil and seeds are properly prepared, to obtain good harvest It is enough to spray the beets once with boric acid at the stage of 4 leaves. As practice shows, the result will be excellent.

Tomato processing

Lack of boron in tomatoes also causes various diseases. Young leaves and branches begin to grow only from below, the base turns black and becomes brittle. In other words, the tomato turns into a bush. Brown spots appear on the fruits, the flesh becomes dry. Some summer residents use a solution of boric acid against late blight.

For prevention, seeds must be soaked in solution before planting. Before planting, this solution is also added to the soil. Care should be taken to carry out foliar feeding before flowering. Boric acid has a positive effect on tomato ovaries.

To speed up ripening and accumulation of sugar, you can re-spray with boric acid at the green fruit stage.

Processing cucumbers

Boric acid is also actively used for cucumbers. This element helps the plant in the process of flowering and ovary.

To improve the ovary and prevent rotting of zucchini and zucchini, a solution is also used: 2 g of the product per 10 liters of water. The plants are sprayed with it.

Use the same boric acid solution for peppers and eggplants.

Processing pears and apple trees

Signs of boron deficiency in pear and apple trees:

thickening of leaves;
darkening and suberization of veins;
leaves warp and fall;
small leaves at the ends of the shoots are collected in the form of a rosette;
the top of the tree dies.

These signs contribute quick drying flowers, deformation of fruits, on which traces of affected tissues appear.

Light spots appear in the apple pulp, which gradually turn brown and turn into a sponge.

Foliar feeding (10-20 g per 10 liters of water) will help restore boron deficiency. Spray the entire crown evenly. The first time - during the opening of the buds, the second - a week later.

Grape processing

A lack of boron is indicated by chlorotic spots between the veins on the leaf and the absence of good ovaries. On soils with a minimal amount of this microelement, new seedlings die within 1.5 years.

Strawberry processing

With a lack of this element, strawberry leaves become dry. To improve the quality of the harvest in early spring a solution of boric acid and potassium permanganate should be poured onto the plantings (1 g of each preparation per 10 liters of water).

Before flowering, it is also advisable to carry out foliar feeding with a solution: 2 g of boron, 2 g of manganese and 1 glass of sifted ash per 10 liters of water.

Processing of ornamental plants

This microelement promotes rapid absorption of calcium and abundant formation of buds. That's why experienced gardeners, actively use this product to obtain beautiful, blooming garden. During the period of bud formation and flowering, foliar treatment is carried out (10 liters of water per 10 g of the drug).

Rose cuttings are immersed for several minutes in a boron solution to prevent fungal diseases.

Drug overdose

Boric acid is classified as the lowest, 4th, hazard class harmful substances. In case of contact with skin, this drug does not harm human health. The danger is that this element accumulates in the body, because it is slowly excreted by the kidneys.

Boron can be a panacea, but it can also be poisonous for plants. After all, an excess of this drug provokes leaf burn. They dry out, die and fall off. Symptoms of an excess of boron in the soil are yellowing of the leaves and curling of their edges. Often the leaves take on a circular shape.

The high content of this substance in forage plants provokes the development of serious diseases in animals.

Insect control

Boric acid is not only useful remedy for plants. This drug allows you to fight harmful insects. Dry mixtures with boric acid are often used to kill ants in the garden. This element accumulates in the body of insects and negatively affects their life, which subsequently leads to death.

Boron acts on the ant's nervous system, causing paralysis and eventual death. When eating the corpses of their fellow ants, other ants also die. Therefore, to get rid of ants in the garden, very little boric acid is needed.

In order to remove these insects completely, it is necessary to use this mixture for 1 month.
