Is it possible to spray eggplants with boric acid for ovary

Spraying eggplants with boric acid is carried out 2-3 times per season. This procedure promotes the formation of ovaries, improved nitrogen absorption, the development of the root system and increased resistance to diseases. For spraying, a solution of a standard concentration of 2-2,5 g of powder per 10 liters of water is prepared. It is preliminarily dissolved in a hot liquid, and then brought to a total volume.

What is boric acid

Boric acid is an inorganic (mineral) acid of formula H₃BO₃. Most often, it is produced in the form of a powder containing small crystals (similar to scales). They are colorless, shiny in the light, and a little oily to the touch. The powder dissolves well in water, but only in hot water (optimally 60-70 degrees).

Acid is used in horticulture as an antibacterial and antifungal agent. For example, you can pickle the seeds of eggplant and other plants in it. In addition, it compensates for the deficiency of one of the most important trace elements – boron, which promotes the formation of ovaries, improves the taste of fruits, and helps to absorb other compounds (for example, nitrogen).

Boric acid for processing eggplant and other plants in its pure form (powder) can be purchased at a pharmacy and special stores for summer residents. It is also included in some fertilizers, for example:

• “Borofoska”;
• “Organo-boron”;
• “Mag-Bor”.

You can buy boric acid at an affordable price at a pharmacy

Benefits for eggplant

Eggplants are sprayed with boric acid for various purposes. Despite the fact that this microelement is required in small volumes (about 2 g per 10 l), it plays a very important role in plant life:

1. Increasing the number of ovaries and preventing their fall – thanks to this, the harvest will be consistently high.
2. Prevention of fungal and bacterial diseases.
3. Prevention of the invasion of pests, including ants and aphids.
4. Improving the taste of fruits and their aroma.
5. Formation of a strong root system.
6. Boron promotes the absorption of nitrogen compounds, so that shoots and leaves grow faster.
7. Increased resistance to adverse weather, infections and insects.
8. Increased pollination (this is important for varieties that need pollinators and grow in greenhouses).
9. Increasing the keeping quality of fruits.

Boric acid deficiency is too dangerous for plants. First of all, eggplants cannot form full-fledged ovaries, which will inevitably affect the yield. In addition, plants become weakened, lose their resistance to diseases and weather factors. If the shortage is severe, some of the bushes may die.

Signs of a Boron Deficiency

Spraying eggplants with boric acid is necessary when there are signs of a lack of boron. Deficiency can be identified by several external symptoms:

1. Growth points die off, plants lag behind in development.
2. Young leaves and shoots are covered with burns, deformed.
3. Some shoots are bent.
4. The leaves take on a domed shape.
5. Affected tissues die and disintegrate.
6. Necrotic spots appear between the veins.
7. Eggplant foliage becomes thin, breaks from touch.
8. The stem is covered with rust.
9. Poorly formed fruits.
10. Dark spots appear on eggplants, and they are noticeable at any stage of fruiting.
11. The tops remain green for a long time – if they are affected, then there is a clear lack of boric acid.

Leaves die due to boron deficiency

If such signs are observed not only in eggplant, but also in other plants, this clearly indicates a lack of boron in the soil. It is worth considering that the trace element is well absorbed in a slightly acidic environment (pH = 5,5-5,8). If the soil has a neutral or even more alkaline reaction (pH greater than 7,0), it must be acidified. To do this, the soil is watered, for example, with a solution of 9% vinegar (100 ml per 10 liters of water per 1 m²).

How to feed eggplant with boric acid

To make the processing of eggplant with boric acid for the ovary, it is necessary to prepare a solution, carefully observing the proportions. How to correctly calculate the dosage is described in detail below.

Boric acid dosage for eggplant

First of all, you need to learn how to accurately determine the concentration of the active substance. For foliar treatments (spraying), it is necessary to prepare a solution based on the ratio of 2-2,5 g per 10 liters of water. And we are talking about a pure substance – boric acid in the form of a powder, which can be purchased at a store for summer residents or at a pharmacy.

To prepare a solution of boric acid, proceed as follows:

1. Prepare hot, but not boiling water with a temperature of 60-70 degrees (the finger should already be burned). It is enough to prepare a volume of 1 liter.
2. Measure the required amount of boric acid – 2-2,5 g. You can weigh or determine “by eye” – from a third to half a teaspoon.
3. Dissolve in a small volume of water, for example, in a liter.
4. Mix thoroughly until the boric acid crystals are completely dispersed.
5. Then bring to a total volume of 10 liters – pour into a regular bucket.
6. Wait until the solution has cooled to room temperature.
7. Pour into a sprayer and start processing.

Foliar spraying is carried out at the stage of bud formation and flowering

Rules for the use of boric acid for eggplant

Eggplant processing is carried out several times:

1. Seed dressing – the day before sowing for seedlings.
2. Watering the soil on the eve of transplanting seedlings, for example, in a greenhouse.
3. Foliar treatment during bud formation.
4. The second foliar top dressing of eggplants with boric acid for the ovary at the flowering stage.
5. Spraying of adult plants during the period of mass formation of fruits.

In all cases, use a solution of the same concentration – 2-2,5 g per 10 liters. For dressing eggplant seeds, 1 liter of working fluid is prepared – this is quite enough. They are kept for 24 hours and then sown in the ground.

A few days before transplanting seedlings to an open garden bed or to a greenhouse, the soil in it is watered with a solution of boric acid, spending up to 10 liters per 1 square meter.

For the formation of eggplant ovaries during the formation of buds and mass flowering, a standard solution of 2 g per 10 liters is prepared and foliar treatment of the entire aerial part is carried out. It is better to work late in the evening so that the daytime sun does not burn the leaves of plants.

Thanks to the treatment with boric acid, the yield will be consistently high

Fruits are treated with a similar composition at the beginning of formation. In the later stages, this should be done, since there will be no special effect. In addition, the last spraying of plants with preparations is carried out at least a week before harvesting.

Conclusion

Spraying eggplants with boric acid promotes the formation of ovaries, increases productivity and strengthens the plant. It is necessary to apply acid, strictly observing the indicated dosages. Plants should be treated at least twice per season – during the formation of buds and at the flowering stage. Thanks to this, it will be possible to get a good harvest, and the fruits will be tasty and keeping.
