Boric acid is a white crystallized powder of natural origin. It can be synthesized artificially from borax, its natural source. Boron is of great importance in the metabolic processes of the flora. In addition, this trace element can act as an antiseptic and insecticide. It is also an excellent fungicide and fertilizer. Thanks to these qualities, the natural chemical is popular with gardeners and farmers. Experienced agronomists use boric acid to get a good harvest of peppers.

Benefit and harm

The plant needs boron throughout the growing season. A colorless chemical odorless substance sold in the form of a powder, packed in plastic bags. Boric acid is sold at any agricultural or flower shop. Before fertilizing plants, it must be dissolved in water. In this case, it is important to strictly adhere to the dosage prescribed in the instructions.

Boric acid has the following benefits for peppers:

• after processing pepper seeds, seedlings appear faster;
• minerals, oxygen and nitrogen are synthesized more actively;
• there is an increase in productivity;
• after antiseptic processing, the vegetable crop is protected from fungus;
• flowering increases, the formation of the ovary improves;
• home seedlings of peppers receive full dressing;
• the harvest is of a higher quality - the fruits are tastier, sweeter and have a longer shelf life.

Based on this, we can safely say that the use of boric acid for plants is a kind of "first aid" to save the harvest. This applies not only to pepper, but also to other vegetable crops.

Now let's consider what the lack and excess of boron in plants leads to. So, with a lack of boron, peppers signal a problem:

• leaves become smaller and deformed;
• the growth of new shoots stops;
• dying off of the upper shoots;
• flowers or ovary fall off without being replaced by new ones;
• abnormal development of fruits.

An excess of boron is calculated by the state of the leaves: they acquire a yellow color and fall off, often take on a domed shape, the tips are bent inward. The disadvantage of using boron is the existing probability of burning the leaves if watering the peppers is incorrect. To avoid this, you can spray the crops with a spray bottle.

Preparation of the solution

More often boric acid is used not as a powder, but in a diluted form. When preparing a solution, you need to control that all crystals are finally dissolved . To do this, a certain portion of the powder must first be diluted in a small amount of hot water (not boiling water!). Then, while stirring, add cold water to the desired proportion. Plants can be treated with an exceptionally cold solution. Watering the culture with a chemical agent is carried out taking into account its appearance. With boron deficiency, plants lose leaves and ovaries, and the bush stops developing.

If necessary, extend the fruiting period and fertilize the pepper, spraying is carried out three times during flowering:

• during the formation of buds - to accelerate development;
• during flowering - to improve the ovary and prevent them from falling off;
• in the ripening phase - to increase the yield.

It is not necessary to fertilize on schedule. It would be better to do this with an eye to the state of culture and its development . With any changes for the worse, you can start feeding. The ideal time to carry out this process is in the evening or on a cloudy day, in dry weather. Effectively prepare a spray mixture by combining boric acid with other preparations. For example, adding a few grains of potassium permanganate to 10 liters of water with a pinch of boron has proven to be excellent. To a slightly pink shade of the solution.

It works well on peppers and glucose introduced into a bucket of water with boric acid in an amount of 10 ml . And to prevent powdery mildew in water, you can dilute a little soda. In order for the solution to stick better to the leaves, it is recommended to add a little tar or 72% laundry soap to the water. With this composition, it is good to handle garden tools.

Application options

Boron does not exist in its pure form in nature - it is represented by boric acid and its soluble salts. To a greater extent, its natural compounds are present in the chernozem chestnut soil. They are virtually absent on land mostly composed of sand or clay, or where liming has taken place.

In this regard, it is important to additionally fertilize them with preparations with boron in the composition: "Organo-Borom", "Microel", "Mikrovit", "Rexolin ABC ". Or prepare the solution yourself. In order for it to benefit the plants, the chemical must be applied in compliance with all recommendations regarding the processing time and dosage.

Seed soaking

A solution is prepared at the rate of 0.2 g of boric acid powder per 1 liter of water. A greater effect can be achieved by diluting the crystals in a decoction of onion peels with the addition of manganese and ash.

The norm of the constituent components is as follows: 2 handfuls of onion husks, 2 g of potassium manganese, 1 tsp. soda, 0.3 g of boric acid powder, a liter can of ash, 2 liters of boiling water

• Pour the husk into 1 liter of boiling water and let it brew. Pour the ashes with a liter of water.
• Mix the resulting solutions into a total solution with a volume of 2 liters.
• Add potassium permanganate.
• Dissolve boric acid in the solution, add soda.

After processing the seeds with this solution, they can be considered disinfected from pests.

Fertilizing the soil

Before planting seedlings or before sowing, it is recommended to apply fertilizers directly to the soil. The soil should be sprayed with a solution of 2 g of boric acid and 10 liters of water. After it must be loosened. You can also sprinkle the powder on the manure before fertilizing the soil with it.

Often, vegetable growers make mistakes in the process of growing pepper, which negatively affect the culture

• Boron deficiency is taken as an excess of the element. To prevent this from happening, a careful examination of the leaves and knowledge of the main symptoms of a lack and an excess of boron are required.
• Root dressing is applied to unmoistened soil.
• Spraying is carried out during the day. Do not spray on leaves when the sun is at its peak. Boric acid under the influence of UV will burn the leaves.
• Excess dosage when watering. This leads to burns to the root system and the tops of the plant. As a result of such treatments, the vegetable crop may die.
• Excessive savings in powder. An aqueous solution with a low concentration of boric acid will not fully cope with its task. The pests will not be destroyed and the pepper will not produce the desired harvest.
• The use of a substance of poor quality, with harmful impurities and additives.
• Disregard of safety rules in the process of working with powder. Boron belongs to toxic chemical elements. When it gets on the mucous membranes, it can cause severe burning and prolonged severe discomfort.
• Excessive use of boric acid. Signs of oversaturation with this component: yellowing of the leaves, bending them with a dome, twisting the tips.

Knowing these mistakes, you can properly water and irrigate peppers in the greenhouse and outdoors with the expectation of a well-deserved harvest.

Top dressing

Root fertilizer. It is necessary to feed the pepper if visual signs of boron deficiency are clearly expressed. To prepare top dressing, you need to dilute 2 g of the drug in 10 liters of water. This solution must be applied under the root of the plants, pouring it from a watering can (this volume is enough to process 10 m2 of plantings). Then the site is loosened. The value of feeding can be increased by mixing the solution with mullein or urea. Fertilizing is especially indicated if the plant begins to lose leaves and ovary. To prevent root feeding from causing burns to the lower leaves, first the plant and soil must be watered.

Foliar dressing. It is carried out throughout the vegetative period. For spraying, a 0.05% solution is prepared from 5 g of powder and 10 liters of water. In this case, it is imperative to monitor the even distribution of the solution over the leaves. It is better to use a nebulizer that gives a misty dispersion.

Treatment against diseases and pests

The chemical, being an antiseptic, helps to destroy pathogenic microorganisms. Spraying peppers with water with boric acid protects them from dangerous fungal diseases: verticillosis, phytoplasmosis (columnar), late blight, black leg. These diseases are very difficult to treat.

For spraying diseased plants, a solution is prepared, the second component of which is potassium permanganate. There is a proven way to defeat late blight, a disease that affects both plants and fruits, showing up on them with brown spots. The secret of the method consists in the following processing sequence:

• first, the peppers are treated with a slightly pink solution of potassium permanganate;
• further stage of processing boric acid in the calculation of 1 tsp. on a bucket of water;
• after 7 days, repeat the treatment;
• fix the effect with a solution of iodine.

Phytoplasmosis is difficult to prevent because insects are the causative agents . Therefore, after working in the garden, the inventory must be treated with the same solution that the peppers are sprayed with. With signs of fungal infection, pepper is sprayed with a more complex composition. To prepare it, you need to dissolve 5 g of boric acid in 1 liter of hot water, and then cool, add 10 drops of iodine, 8 drops of potassium permanganate and 1 tbsp. l sodium humate. Bring the volume to 10 liters with water and spray the planting of pepper with it. In one season, pepper is fertilized with such a composition up to 3 times. Irrigation is best done in calm, dry weather, early in the morning or in the evening with a freshly prepared solution.

The fertilizer is prepared at the rate of consumption - 1 liter per 10 m2.

Pest control

Yield damage is caused not only by a lack of minerals and the presence of fungal diseases, but also by insect pests. Planting pepper is required to handle aphids, ants, spider mites, slugs . Boric acid powder is also very effective against them. For ants, prepare the following bait: 5 g of boric acid powder is diluted in 1⁄2 cup of hot water, sugar is added to the water in the amount of 2 tbsp. l. and 1 tsp. honey (can be replaced with jam). The mixture is thoroughly stirred and poured into containers with low sides. They are placed between plants where pests have been seen.

In the composition for spraying leaves from insect pests, it will be useful to add 1 tbsp to a bucket of water. l. liquid soap and wood ash in a volume of 1 cup . The chemical must be handled with care so as not to harm the seedlings. Boric acid treatment of peppers, like other crops, is harmless to humans and pets. But precautions are still necessary: with a long pollination procedure, it is advisable to take care of individual protection in the form of a respirator or gauze bandage.

It is not difficult to use the drug, especially since it is available for purchase. You just need to carefully monitor the seedlings and carry out processing in a timely manner. Then a generous harvest of healthy vegetables will be provided.
