What products contain acid

Boric acid is an excellent antiseptic, but the concentrated solution is only suitable for external use. Since the substance rarely causes irritation, it is added to various ointments, water or alcohol-based solutions. Boric ointment is used as an antiseptic and drying agent, but you need to be careful with its use and avoid contact with mucous membranes.

Acid is also found in teimuric paste, which is suitable for dealing with diaper rash. The alcoholic solution of the chemical contains acid and ethyl alcohol and is widely used to treat otitis media. Boric acid has a good antimicrobial and antiseptic effect. Ease of use and affordability of the product allow it to be popular today among many modern cosmetic products to combat rashes.

Overdose and its consequences

If you do not follow the instructions and increase the dose of the drug, side effects often occur. Skin deterioration is especially common in people with dry and sensitive skin. The substance is absorbed very quickly, and especially through the delicate baby skin. If a child smears an ointment or solution on a large area of his body, the consequences can be very serious. In case of an overdose, the following conditions are possible:

It is also worth noting that boric acid is perfectly combined with various other components - zinc oxide, naphthalan oil, salicylic acid. Often, it is boric acid as a preservative that is added to various ointments to extend their shelf life. In addition, boric acid is an excellent fertilizer for your garden and vegetable garden.

MirSovetov will tell readers in more detail about how boric acid and its derivatives are used.

Traditional and folk medicine

Traditional medicine has appreciated the properties of boric acid. Today it is used in many cases. Various drugs that contain boric acid: solutions, creams, ointments, pastes, powders, most often contain 2-5% of this agent. Basically, all of them are disinfecting or antipruritic drugs and they are prescribed for dermatoses of various etiologies, especially if they are at a progressive stage - this includes exacerbation of diseases such as neurodermatitis, dermatomycosis, eczema.

As for traditional medicine or cosmetology, experts here also highly value boric acid. For example, it is part of a lotion, which is an excellent remedy for caring for the surface of the skin with such a phenomenon as excessive sweating (hyperhidrosis). Boric lotion copes well with this nuisance. To prepare it, you need to take in equal proportions vinegar (ordinary table), an aqueous solution of boric acid (best of all 4%), cologne (any, at your discretion, to add flavor to this tool). After the surface of the skin suffering from hyperhidrosis is lubricated with lotion, it is necessary to powder these areas on top with any powder - ideally for children.

Boric acid applications

Alcohol solution.

The boric acid-based alcohol solution also contains ethyl alcohol. Depending on the concentration of boric acid, the application of the solution is also different:

if the concentration is from 0.5% to 5%, then such solutions are used as an antiseptic. This drug is available in 10 ml vials;
if the concentration is from 3% to 5%, then this is an excellent remedy for the treatment of ear diseases, especially (including chronic ones).

Do not use drugs with boric acid for children.
Breastfeeding mothers should not use boric acid on their teats.
It is undesirable to treat large areas of the body with preparations containing boric acid.

Boric acid in agriculture

Boric acid is an excellent micronutrient fertilizer that is used to feed various crops during their growth. Thanks to the properties of this agent, the plants have better nutrition for the ovaries and the yield increases.

Boric acid contributes to the fact that the number of ovaries increases on fruit and berry plants, new growth points are formed, both stems and roots, the sugar content in fruits increases, the likelihood of diseases in plants that appear due to a lack of boron decreases. By the way, potatoes really feel a deficiency of boron (they grow much worse, small tubers are formed), beets, tomatoes (the stem turns black, the leaves are brittle, the fruits have brown spots), apples and pears (the leaves are wrinkled, brittle, the fruit develops necrosis).

Thanks to top dressing, which contains boric acid, plants become more resistant not only to diseases, but also to unfavorable weather conditions. Experts note that thanks to boric acid, the yield increases by an average of 20%, or even 25%. Especially, such high rates for cucumbers, tomatoes, cabbage.

Seeds are treated with boric acid before planting - they are soaked for 12-24 hours (0.2 g of boric acid is diluted in a liter of water).
Boric acid is applied directly to the soil before planting seedlings or seeds (2 g per 10 liters of water).
Boric acid is sprayed on the leaves (5 g per 10 liters).
In addition to pure boric acid, such ready-made fertilizer as borosuperphosphate is also used: granular or double.

Instructions

For the treatment of various diseases, a solution of boric acid of different concentrations is used. So, when and washing is performed with 2% aqueous solution, and - 3%. Due to its accumulation in tissues, it has a prolonged effect on the source of infection, as a result of which recovery occurs much faster than when using other antiseptic drugs.

Despite the fact that boric acid dissolves in cool water, it is better to use warm water to prepare the medicine. In this case, there will be no undissolved crystals in the solution, which can harm the inflamed mucous membranes.
Boil a glass of water and cool it to 38-40 degrees.

Slowly pour a teaspoon of boric acid powder (without a slide, i.e. about 4-5 grams) into warm water. Stir the solution thoroughly until you are sure that the sediment at the bottom has completely dissolved.
In the resulting solution, moisten a cotton pad and treat the cavity between the eyeball and the posterior surface of the eyelid (for conjunctivitis).

Pour a teaspoon of boric acid powder (in this case - with a slide, i.e. about 6 grams) into a glass of warm water and mix thoroughly until the sediment disappears. For skin diseases, make lotions with the resulting solution.

With prolonged use, side effects may occur: nausea, headache, rash, kidney problems, etc. For this reason, the drug is not recommended for patients with nephritis, pregnant women and children. If you do not fall into the above categories and are a relatively healthy person, still do not apply the solution to large areas of the body.

Indications for the use of acid

Boric acid has many indications for its use. An aqueous solution of such a drug is recommended to be used for the purpose of applying lotions directly to weeping foci with dermatitis. In addition, it can be actively used to wash the skin in case of redheads. A 2% aqueous solution can be used as rinsing procedures for the mouth, pharynx and pharynx, as well as for washing the urinary tract.

A saturated solution of boric acid helps to heal pityriasis versicolor. To do this, it is necessary to rub this drug into the lesions once a day for a week. It should be borne in mind that after the disappearance of the rashes, you should continue to rub the area of the former lesions with the medicine several times a week for about a month. The alcoholic content of boric acid has an antiseptic and antipruritic effect, it is used to wipe the skin around the foci of pyoderma.

The powder form of this medication, as a rule, is used for the purpose of blowing into the ear for ear diseases. In addition, the powder in combination with an alcohol solution is used as ear drops, as well as for wetting turunda in the presence of chronic otitis media. Ointments containing boric acid are used for the treatment of psoriasis, eczema, neurodermatitis, dermatomycosis.

Also, 5% boric ointment is used in case of dryness and cracks in the skin. Boric acid foot baths help to cure diseases such as hyperhidrosis. In addition, for fungal infections of the feet and diaper rash, this tool is widely used in the form of a powder for dusting.

In addition, in rare cases, a state of shock may occur.

Boric acid is an active substance, it can be in the form of colorless slightly oily flakes or in the form of a finely dispersed crystalline powder. It dissolves well in both water and alcohol.

The effect of the drug "Boric acid"

Boric acid easily penetrates into many tissues, as well as into organs, and can also accumulate in them. It is excreted from the body rather slowly, 50% is excreted through the kidneys in about twelve hours, and the rest leaves the body within five days or one week.

When a 5% solution of boric acid is used, the processes of phagocytosis are suppressed, when a 2–4% solution is used, the growth and development of pathogenic microorganisms is inhibited.

Boric acid has an irritating effect directly on the mucous membranes of the body. When absorbed, the active substance causes some systemic effects of a toxic nature. In young babies, it penetrates well enough through the skin and mucous membranes, there are confirmed deaths when this substance is ingested, as well as when excessively applied to damaged skin.

When boric acid reintroduced into the baby's body (after processing the mammary gland before breastfeeding), the following symptoms were noted: hypotension, metabolic acidosis developed, and kidney function was also impaired.

Conclusion

Before using Boric acid, you should consult a doctor.

For good growth and development of plants, fertilizers and feeding are necessary. The modern assortment of mineral fertilizers allows you to choose a product for each crop for any stage of development. Among them there is a simple remedy proven by more than one generation of gardeners - boric acid... Why do plants need boric acid and how much of it is needed to help, not harm plants, we learn from the article.

Boric acid: description

Under natural conditions, unbound boric acid is mined in some volcanic areas of Tuscany, the Lopar Islands and the state of Nevada.

In addition, it is sometimes found as a constituent of most of the following minerals: borax, colemanite, boracite. And also this element of the periodic table is present in seawater and is a component of all plant cells without exception.

Boric (orthoboric) acid belongs to inorganic acids. Usually it is a milky crystal, slightly soluble in cold water. They lose moisture when heated, turning into metaboric acid, then into tetraboric acid, in the final boron oxide is obtained.

All described combinations, upon contact with water, are transformed into boric acid.

The boric acid compound is often used:

in medicine as an antiseptic;
in gardening and horticulture;
industry.

Boric acid is a convenient microfertilizer, is often used in agronomy, with a lack of boron in the soil. The substance in the powder contains the trace element boron, which is required by the flora during the period of ovary formation.

What is boric acid for in the country?

Boric acid is a very necessary element for all fruit and berry and vegetable crops and flowers.

It has a number of useful properties:

getting rid of pathogens;
increased yield;
influence on the taste of vegetables and fruits.

In addition, plants treated with boric acid become much more resistant to adverse conditions. Acid is used in the form of solutions for irrigation or as additional soil enrichment.

In addition, boric acid is used as a deterrent or wasp:

Add boric acid powder in places where insects are located.
Pour 5 g of boric acid into half a glass of boiled water, place, attach a spoonful of honey and 2 tbsp. tablespoons of sugar, mix and pour on a wide plate, place near the ant paths.
Mix two boiled eggs with half a teaspoon of boron... Sculpt small balls and place in places where insects stay.

The need for plants in boron

Boron for vegetation - the "present" substance - is required during the entire growing season.

However, the excessive presence of boron in the soil poses a threat to the flora.

Negative consequences of exceeding the compound in the soil:

burn of the lower shoots;
drying out the borders of the sheet.

It is necessary to take into account the differentiation of the needs of each plant in the substance.

According to the needs for boron, plants are divided into groups:

High demand: fruit trees (pear,), beets, rutabagas.
Average demand:, lettuce, berry bushes.
Small need: herbs, legumes, and strawberries. Although potatoes belong to the low-consuming boron group, the deficiency of the element is manifested much more.

Signs of excessive boron content:

convex leaf shape;
turning inside their borders;
yellowing of the leaf as a whole.

Adult leaves are yellowed first. An excess of boron concentration in fodder plants provokes chronic diseases in animals.

Common signs of boron deficiency in plants

There are simply no alternatives to boric acid for use in the garden or vegetable garden.

The lack of this substance in plants is manifested:

leaves at the top of the trunk are noticeably yellower;
young leafy shoots of irregular shape, weak, wither very soon;
only the buds from the sides fully ripen, they simply are not at the tops;
areas of dying appear on the trunks and fruits;
the upper sections of the processes die; flowers fall off;
scab appears on root crops;
cabbage leaves get sick with rot.

How to grow more crops?

Any gardener and summer resident is pleased to receive a large harvest with large fruits. Unfortunately, it is not always possible to obtain the desired result.

Plants often lack nutrition and minerals.

It has the following properties:

Allows increase yield by 50% in just a few weeks of use.
You can get a good harvest even on low fertile soils and in adverse climatic conditions
Absolutely safe

Soil types by boric acid content

Boron is one of the main trace elements for the existence of the flora of our planet, provides:

the required amount of synthesis of nitrogenous compounds;
optimizes the metabolic processes of plants;
positively affects the growth of the presence of chlorophyll in plant cells.

The soil in which the boron content is equal to the norm is considered positive. On plants, this is reflected in the form of an increase in yield, quality of fruits, tolerance of negative conditions and diseases.

Boric acid (Н3СОз) - the most acceptable and democratic a method of obtaining a good harvest and therefore common among gardeners.

Boron is colorless and odorless, a crystalline compound that dissolves easily with water and has inexpressive acidic characteristics.

It is used on podzolic-soddy, gray and brown forest soils, but it can also be useful in chernozem areas on light soils.

Vegetable gardens need similar fertilization:

with a soil with a large presence of carbonates;
in dark-colored or peaty soils;
in acidic soils.

The use of the connection contributes to:

quantitative growth of inflorescences on fruit trees and shrubs;
the emergence of a larger number of growth points of branches and roots;
regulates the concentration of sugars and the taste characteristics of fruits.

Boric acid - instructions for use

This compound is used for agronomic purposes in the following forms:

powdery;
liquid concentrated solutions.

For irrigation, fertilization, top dressing, different proportions of the substance are used in relation to the solvent - water. The ratio depends on the condition of the plant and the purpose of the procedure. Can be used in combination with other elements: zinc, manganese.

Foliar dressing

Spraying the aerial part of the plant with a boric acid solution is an effective measure. The ratio of the product is 1 liter: 0.1 mg of a powdery substance.

Top dressing is carried out in three phases:

initial processing perform at the stage of peduncle development;
second- at the stage of flower opening;
third- at the stage of fetal emergence.

In some circumstances, the boric solution is mixed with other agents. For such spraying, a small dosage of the element is required (5-6 g per 10 l of water).

Foliar treatment with boric acid is performed completely excluding direct sunlight (burns), optimally on a cloudy day or in the evening. If the procedure is carried out on a sultry day, then the tree or shrub must first be doused with water.

Root dressing

Top dressing with boric acid at the root is performed as infrequently as possible. It is important to make sure of the lack of this substance.

Boron enrichment is used for:

planting decorative floral flora;
in conditions of germination on impurities of peat and sand;
on podzolic, soddy soils.

Preparation of the mixture in the following ratio: 0.1-0.2 g of the powdery agent is diluted in 1 liter of water. However, before using the mixture for spraying, each plant is doused with plenty of water to prevent chemical attack on the leaves.

Boric acid for different crops

For fruit trees

Manifestation of a lack of boron in apple and pear:

leaf plates become thicker;
there is corking; change in the color of the veins;
at a critical value of the deficit, the leaves fall off.

The rosette of the leaves is found - small leaves of the upper parts of the processes do not open. In unkempt apple, pear or other trees, the upper parts dry out.

Lack of boron in apple trees provokes a disease referred to as "internal corking of apples":

More clarified fragments appear inside the apple, with a circumference of up to 1 cm.
Over time, they darken and the content becomes a porous, tasteless mass.
On the outer surface of the apple, swollen, irregularly shaped crusty and speckled growths are formed.

Foliar spraying of the solution (10-20 g of boric acid per 10 liters of water) significantly increases fruit formation. The procedure is performed after a decline in the activity of the sun in the evenings or with a tight palate in order to avoid burns.

The crown will be processed equally on each side twice:

at the beginning of the opening of flowers;
after 5-7 days after the first time.

This measure has a positive effect on reducing the fall of ovaries, the yield increases significantly. And also there is immunity to diseases, endurance and keeping quality of fruits.

On hot days, before spraying the solution, poured a large amount of water over the trees.

After flowering, the crowns of apricots, peaches and cherries are sprayed with a mixture of trace elements per 10 liters of water:

60 g soda ash;
20 g of copper sulfate;
10 g boron powder;
1 g of potassium permanganate;
10 drops of medical iodine.

For vegetables

The positive effect of boric acid on plants is diverse, the substance contributes to:

an increase in the number of inflorescences;
general development;
affects the taste and size of fruits and vegetables.

However, the excessive presence of boron is harmful to plants.

Each crop requires the presence of boron in different proportions:

Great need of this substance in fruit, all types of cabbage and beets.
Less need for boron: carrots, tomatoes, lettuce and all stone fruits.
I have little need for substance tons: potatoes, legumes and strawberries.

The use of the solution strengthens the seedlings, at the time of flowering prevents the death and shedding of inflorescences.

For tomatoes

The low content of boron in the soil in tomatoes has the following characteristics:

overwhelming black spots;
fragile young trunks;
dark spots on tomatoes.

Foliar enrichment with boric acid 10 g: 10 l is performed at the time of inflorescence formation and in the growth phase of green tomatoes in order to optimize the palatability and stimulate the fastest increase in volumes.

Boron is carried out at the stage of full germination of the fourth leaf.

The following substances are added to 10 liters of water:

0.5 g boron;
10 g superphosphate;
8 g of potassium chloride.

This solution volume is sufficient for about 200 plants.

To protect tomatoes from late blight, tomatoes are treated with a composition of powdered boron and iodine from the second half of June:

dried leaves are treated with unsaturated potassium permanganate;
after a week, boric solution is sprayed (1 g per 10 liters of water);
further, after a seven-day period - with an unsaturated 1% iodine composition.

Spraying boric solution on tomatoes in greenhouse conditions for prevention is carried out once every 30 days: a 10-liter bucket requires 2 g of boron powder. When there is a lack of boron, top dressing is carried out with a saturated composition: 10 g of boron per 10 liters of water.

Learn more about the use of boric acid for tomatoes from the video:

For cucumbers

leaf borders;
vertical yellowing on ripe cucumbers;
stopping growth;
dying off of inflorescences.

The supply of boric acid to the ground part of the plant is carried out three times during the growing season with the means in accordance with the instructions:

Kelkat Bora;
Bor-Mag;
Green Belt.

Spraying a mixture of 5 g of boron and 2 g of manganese sulfate in a vegetable garden with a two-week interval will help eliminate the death of inflorescences and get a significant harvest. In greenhouse conditions, manipulation is carried out 2 times a month.

In order to obtain a larger yield and long-term fruiting at the stage of the emergence of flowers, it is good to irrigate with the following composition:

0.5% potassium chloride;
5% superphosphate;
0.1% magnesium sulfate;
0.03% boron in equal amounts.

For pepper and cabbage

The small amount of boron in the soil in pepper is determined by:

has small leaves of irregular shape;
stop in the growth of branches and shoots;
death of inflorescences and ovaries.

An insufficient amount of the element for cabbage is found in the form of a hollow head of cabbage.

Colored for boron deficiency reacts:

vitreous ovary transparency;
irregular shapes;
peduncles with rusty shades;
bitterness.

The processing of cabbage with boric acid with manganese sulfate mixed with water is performed three times in a ratio of 10: 1: 1:

during the budding period;
during inflorescences (when 5 full-fledged leaves have grown);
during the period of fruit formation.

Boron gives cabbage density and yield. Providing cauliflower with this element and molybdenum in a ratio of 2.5 g: 2.5 g: 1 l of water is carried out at the stage of 4 leaves in order to increase the growth rate by 7 days.

For beets

The lack of an element in sugar beet is manifested as sores at the tops or rotting of the core... The stern has an internal spoiled part with a smoldering smell.

Processing of beets with boron solution 1:10 is carried out after 14 days, immediately after the initial enrichment of the soil at the stage of formation of full-fledged 5 leaves.

To keep the leaves from diseases, a solution is sprayed:

15 g of potassium chloride;
5 g boron;
1 tbsp. l urea.

For potatoes

Boron deficiency in potatoes indicates the appearance of scab. The first germinations are formed at a slow pace, yellowness appears on the leaves, the main trunks and stems are brittle. Experts find a certain consistency: good potato tuber = boron + optimal soil composition.

The need for boron is observed in soil types:

in podzolic sod;
circus;
peat.

Areas with an overestimated presence of limestone, potassium, carbonates, and nitrogen have the same need for boron. Equipping the soil with phosphorus compounds is capable of minimizing the need for this element in the soil.

With the initial signs of scab, it is important to spray the potato area in time with a mixture of acid in 6 grams and 10 liters of water, this volume is enough for 10 square meters. m. To prevent the disease, the seeds are treated at the stage of preparation for planting or sprayed onto the initial seedlings.

For bow

Soaking onion seeds before planting in 0.2: 1 l boric fluid will ensure health and disease resistance. Watering with the addition of boron 5g: 10 l enriches the plant roots with oxygen.

Spraying water containing boric acid (5 g) increases the amount of onions harvested in the fall by 23%.

The effect of boric fertilizers in dry and hot summers is not higher than in cool and cloudy ones with frequent precipitation.

For eggplant

It is useful to moisten eggplant seeds in boron liquid: 0.2 g per one liter of water, for 10-12 hours. Treatment of plants by dissolving 2 grams of boron in 10 liters of water is used when decaying eggplants that are gaining mass.

Watering with boron water during flowering will increase the number of vegetables per plant.

For strawberries

To obtain rich-sugar and fleshy fruits, strawberries and strawberries are periodically sprayed with berry bushes. If you do not carry out such events, lack of boron will manifest itself as drying and folding of sheets.

Processing is first carried out before disclosure and while the fruits reach a certain size.

In other cases, experts recommend immediately after the snow melts to water the area with strawberry plants with boric acid according to the instructions for using the substance in summer cottages. In addition, up to 5 drops of manganese are added to the solution. Ten liters of solution is enough for 50 bushes. And also at the time of the formation of ovaries, it is useful to spray a solution of 5 grams of powdered boron and 10 liters of water.

During the ripening period of the fruit, add an auxiliary mixture in the form of:

200 ml of water;
boric acid;
manganese ash, in a ratio of 2: 2: 1.

For grapes

When boron is lacking, including the best varieties, it bears fruit in small clusters. The first warning of a boron deficiency is white patches on the leaves. To get rid of chloride areas and small berries, as well as measures to prevent this, the use of boric acid is included.

To this end, the vines are sprayed at the first sign of plant malaise. A one-time measure is often enough. They are processed during the beginning of flowering, with this care, the flowers will cease to crumble, which will affect the yields.

The yield will increase if, at the stage of preparation of the solution (5 g of powdered boron per 10 liters of water), add 5 g of zinc. Duplication will not hurt during the ripening of the fruit.

For indoor plants

For spraying indoor flowers and ornamental plants in general effective drug "Pokon"(boron included liquid in a green vial).

Boric acid is suitable for the growth and flowering of orchids - the flower is processed during the growth of the arrow and then during flowering to form a new one.

Before planting, cuttings of roses are placed in an unsaturated boric solution and after 5 minutes they are planted in the ground. For indoor citrus fruits, boron is no less important, since during the flowering period it strengthens the plant, preventing diseases and negative factors from affecting fruiting.

Boric acid preparations

In special outlets you can find a large selection of all kinds of fertilizers, including those containing boron. For processing tomatoes, cucumbers, and other crops of the third group, the "Mag-Bor" product is suitable(Dilute a 20-gram sachet with 10 liters of water, the solution is used for 3 square meters).

And you can also prepare a solution for frequent use from saturated boric acid distributed in a 10-gram package or a boron-magnesium supplement with a 13% concentration of boric acid and 14% magnesium oxide. Experts in agrotechnical chemistry advise using boric superphosphate and borax (sodium boric acid) as the main fertilizer.

Human and domestic animal exposure to boric acid

Boric acid is used in the treatment of lichens. In this case, a 3% alcohol solution is used.

Recipe against fungal infection:

Pour 1 teaspoon of boric acid into prepared dishes (enameled), then pour in 100 ml of water.
Bring to a boil at low heat, it is necessary that the crystals dissolve completely.
Remove from heat, cover with a thick cloth, allow to cool.

Every day, you need to wipe the spots and areas of the skin surface around the lichen with a solution. After wiping, do not dry the rash, but wait until it dries by itself. At the same time, small particles of the substance appear. Do not rinse areas.

Helps this substance in getting rid of fleas in pets... It acts on cockroaches and fleas similarly to any acid - it destroys the chitinous membrane, without which fleas die. The poison from the mini-crystals of boric acid powder easily sticks to the flea's protection, and then there is no longer any hope of survival.

The advantage of this cheap drug is that it
