Why do eggplant leaves dry

Eggplant belongs to the nightshade family. They love warmth and die when frozen. Before landing, you should understand the causes of possible diseases. Consider why eggplant leaves dry and how to avoid such a problem?

Why do eggplants dry in a greenhouse?

If dryness still manifests itself in the greenhouse, the reason is the lack of trace elements. The soil is not fertilized, dries and poorly moistened.

Stimulates the growth of eggplant nitrogen. This element is responsible for the normal development of a vegetable crop. And with its lack, even if it is properly watered, given normal lighting and maintain the desired temperature in the greenhouse, the lower part of the bush will wither and dry. It is necessary to immediately fill up the nitrogen deficiency, and the seedlings will acquire a healthy appearance.

Why do eggplants dry in the garden?

After transplanting from the greenhouse to the open ground, the leaves of eggplant seedlings dry very often. This is a normal occurrence. So seedlings respond to stress. Especially this phenomenon is observed with a sharp change in temperature. The second reason why the leaves of eggplant seedlings dry out is the improper care of the sprouts in the initial stage of development. If you take good care in the future, then the green and healthy look will return to the plants.

If the eggplant dries at a later stage, then it is a matter of improper care or illness. Incorrect care includes:

  • violation of crop rotation;
  • lack of lighting;
  • poor top dressing;
  • hypothermia;
  • lack of air;
  • temperature changes;
  • violation of the watering regime.

It is very important not to disturb the crop rotation and follow the rules of consistent planting. This will help to avoid poor plant development. All necessary nutrients will remain in the soil.

Prolonged exposure to the sun also causes dryness. Ultraviolet light contributes to the breakdown of chlorophyll. It is this element that allows plants to breathe, promotes photosynthesis. The upper cover receives burns from the sun. At first it looks like yellow dots. Then it can go into complete drying. Therefore, you need to pay attention to how the beds are located on the field or in the greenhouse. To avoid burns, you can shade the windows in the room or arrange the beds in another way. You can cover with paper or cloth in the hottest period from 12 to 15 hours of the day.

Types of leaf deformation and methods of struggle

Deformation can manifest itself in different ways. One type of deformation is its wilting. This is the first signal before yellowing and further dryness.

Typically, this phenomenon occurs on a bright sunny day, and later in the evening the bush can fully recover. If you feel a musty smell from the ground - the soil is excessively moist. It is necessary to dry it by skipping the next watering and loosening the earth near the bush. If this happened in a greenhouse with seedlings, before planting it in a permanent place, then you can simply transfer the eggplant into another box and add new dry earth.

The leaves are the first to take the blow from the temperature difference. From this, they can fade, lose elasticity, go stained, and later turn yellow and dry. To avoid this in the greenhouse, you need to raise pots with seedlings higher. About 20 cm from the ground. To prevent this from happening in the open ground, it is necessary to maintain the necessary timing of transplanting seedlings or sowing seeds.

For a successful harvest, you can not supercool a plant

The same conditions apply to hypothermia. Often with incorrect hardening, deformation occurs. Before the procedure, be sure to water the seedlings. Seedlings do not like cold water. You need to water it with heated water. Otherwise, the sheet may curl, start to dry and die

Another type of deformation is the appearance of black spots before the germ completely dries. This causes a disease called the Black Leg. Seedlings are removed completely. The remaining healthy seedlings are sprinkled with ash. This will draw excess water from the ground. Subsequently, Previkura is introduced.

Disease

Eggplant culture is susceptible to fungal and viral diseases, which also sometimes lead to its drying. Such diseases include:

  • Fusarium and gray rot;
  • speckled, cucumber or tobacco mosaic;
  • verticillosis;
  • late blight.

Fusarium and gray rot

Fusariosis is one of the most unpleasant fungal diseases. The microorganism lives in the earth and infects weak plants. Often gets into the ground along with poorly processed seeds. Fungi grow from spores and penetrate into plants that were injured during transplantation or caring for them. Diseased plantings differ from healthy ones in their appearance:

  • lag behind in development;
  • a brown coating appears on the stem and on its cut;
  • pinkish roots;
  • pink shade of the root part of the stem;
  • yellowed, dried-up leaves with light veins;
  • cotyledon leaves are twisted into tubes.

Gray rot is distinguished by a touch of white. At first it is fluffy, then it turns gray. The bush is dying.

Late blight

From late blight, brown spots first appear on the lower leaves. The whole plant is sick: both leaves, and stems, and fruits, if they have already appeared. Gradually, everything turns black.

Vertisillosis

The fungus Verticillium causes vertisillosis disease. This is manifested by yellowing, dryness and falling of the upper cover. First, the affected areas become variegated, the veins turn yellow. Then the disease captures all the vegetative parts. They begin to twist into a spiral, dryness and subsidence. Lesions are similar to burns with boiling water. If you make a cut, you can see that the stem inside has turned brown.

Methods for controlling viral and fungal diseases

To destroy the fungus, you need to use special store tools: Quadris, Antracol, Consult.

Phytosporin and radomid work well. These are more radical means. After processing, the result should be expected 20-25 days.

Mottled, cucumber, or tobacco mosaics are viral diseases. So that they do not appear, it is necessary to observe the principles of crop rotation, weed well and clean the remains of plants between the beds. Improper watering temperature can also cause these diseases. Therefore, it is important to follow the recommendations for watering, air and soil temperature.

There is only one way to deal with vertisillosis. Sick seedlings or plants are burned. In no case should the residues be thrown into the compost so that the entire compost pit does not become infected and then other vegetables become infected.

You need to transplant healthy vegetables to another place. If this is seedling, then a new, processed box with the ground. Subsequent treatment with fungicides. Such as Previkur, Rovral or Topsin.

Prevention

In order to avoid yellowing of leaves or fruits, they should be treated with any of the types of bacterial bio-fungicides in advance. This is done 10 days after disembarkation. And a week before the harvest.

Also, to avoid putrefactive processes in the roots and stems, you need to regularly and well ventilate the greenhouse, pinch and weed the bushes.

Conclusion

Errors in care provoke dry leaves. It is necessary to adhere to strict recommendations when preparing seed material during planting, as well as when caring for the plant at all stages of growth, and a healthy harvest is guaranteed.
