Why do peppers rot on a bush in a greenhouse and what to do

Summer gardeners want to grow as many different crops as possible on their plot, so that everything on the table is homemade, grown with love and with their own hands. Many of us ask a natural question: why does pepper rot in a greenhouse? After all, it is not exposed to direct sunlight, rain and wind. It is very sad that after hard work, our plants begin to get sick. It seems that everything is done correctly: a greenhouse is equipped and watering is regular, but the crop is dying. Let's look into this issue in more detail.

What conditions are needed for the growth of sweet peppers

Conditions necessary for the normal growth and development of sweet pepper bushes:

loose light soil;
humidity not higher than 60%;
watering as the topsoil dries;
proper fertilizer;
ventilation mode;
soil temperature within 25 degrees.

These five points are the basis of a good harvest of peppers.

Diseases of bell peppers

The causes of the disease of bell peppers can be violations of one or more conditions for their growth. For example, elevated temperatures or humidity, unbalanced top dressing, poor quality heavy soil or lack of ventilation. Consider some of the main types of pepper diseases:

Blossom rot.
Late blight.
Black leg.
Spotted wilt.
Gray rot.

Blossom Rot

If brown spots appear on the pepper, then this is the beginning of the disease of blossom end rot. It is manifested by the appearance of dark brown spots on the tops of the fruits, which grow. These patches are dry to the touch. With further development of the disease, the spots become larger and flat or depressed areas of dry rot appear. Affected vegetables stop growing and ripen quickly. It is impossible to eat such fruits that have been affected by blossom end rot, as they taste bad and they will not bring benefits.

Some recommendations:

When studying blossom end rot, it was found that in 90% of cases of this disease, the cause is irregular watering at elevated temperatures.The regularity of soil moisture, temperature and humidity should be optimal (temperature 18-22 degrees, humidity 60%). With an increase in air temperature, watering should be frequent and vice versa. Airing the peppers in the greenhouse also plays an important role.

Folk treatments for vertex rot

What to do if top rot has started on sweet peppers:

One liter of milk is poured into a bucket and topped up with water up to 10 liters. This solution is applied to the leaves and fruits of pepper once a week. Repeat the procedure 2-3 times.
Also use dried eggshell crushed in a mortar. It is crushed into a powder, which is sprinkled on the holes before planting seedlings in them.
Two tablespoons of powdered chalk mixed with one liter of warm water and watered the bush with defeat.

However, it must be remembered that excess calcium can lead to a lack of potassium in vegetables, and this is fraught with disturbances in fruit ripening. Therefore, an integrated approach and moderation in fertilizing the soil is necessary.

Light blight

A frequent disease of peppers is late blight. To the question: why do pepper fruits turn black, we can definitely say that this is due to the penetration of phytophthora fungus into the vegetable cells. The onset of the disease is characterized by the appearance of small spots of a dirty green color on the fruit. Then these points become large and blackening spots and spoil the entire bush. The leaves of the bush of the plant become twisted, as if they were burned. The plant dies. And fungal spores spread to neighboring plants and enter the soil.

Recommendations for disease prevention

Peppers are treated for phytophthora with special chemicals. And prevention is carried out with a solution of Bordeaux liquid, also by spraying with Fitosporin-M, calcium nitrate, etc. Airing in greenhouses and watering the bushes with warm water also plays a very important role.

Black leg

Blackleg usually affects seedlings of peppers. But it can also affect fruits when its spots appear on the fruits. It is characterized by the fact that on the bush, closer to the root, a dark gray or black area of necrosis appears. Then the root rots and the plant dies. Infection with black leg on pepper can be prevented by soaking the seeds in a solution of potassium permanganate and watering the seedlings with a warm, weak solution of potassium permanganate. The antifungal drug of natural origin "Fitosporin" also works very well.However, if the stems turn black, then such plants are urgently removed from the site and burned.

Spotted wilt

The answer to the question: why do peppers rot in a greenhouse on bushes, may be that the plant has caught spotted wilt. This disease begins with dark spots of yellow or brownish color appearing on the leaves. They look like sunburn, so the appearance of dark ring dryness on the leaves and on the fruits of the pepper is often confused with them.

The reason for the appearance of bronze is that insects carry this disease: aphids, cicadas, thrips. If insects appeared on the plants, then they must be treated with appropriate insecticides, and the plant should be treated with Fundazol.

Grey Rot

Grey rot of peppers develops when the plant gets into conditions of very high humidity and heat.It affects all parts of the plant. The stem can rot, as well as the leaves, fruits and flowers of the plant. Rotting contributes to the reproduction of gray mold fungi. If the greenhouse air is very humid, then the disease will cover a large area of \u200b\u200bpeppers very quickly. Why the whole crop may die.

In the event that sweet pepper grows on the street, in the garden, then never plant it under trees and shrubs. Gray rot may appear after prolonged rains or with insufficient air aeration. This can happen if the planting of peppers is thickened or the ventilation in the greenhouse is poor.

Tips:

Treatment for gray mold should be carried out immediately after its first signs are discovered. The bushes are treated after removing the affected areas of the plant and fruits with a fungicide solution.

Prevention from the disease is important. It consists in observing the norm of soil and air moisture.
