Poor conditions and care

Often, such spots form on plants due to poor growing conditions and improper care.

  • Insufficient lighting. This is the most common cause of white spots. They form on the leaves. In order for the pepper to develop normally, daylight hours must last at least 13-14 hours. Often, young crops at the end of winter do not have enough natural light. This can be bad for development.

  • Wrong pick. Shoots initially need to be grown in the ground, as this culture does not like when the root system is affected. You can use peat tablets, in which case the roots will have their own space for growth, while diving will not cause stains.

  • Nutritional deficiency. During the active growth of peppers, the soil begins to become very depleted. All this can adversely affect the condition of the plants. It is important to control that there are nutrients in the ground. And also it is necessary to periodically apply feeding substances.

  • The wrong place. Some gardeners plant peppers in areas that are too bright. At the same time, it is better for them to select shaded places. Too much sunlight can also cause small white patches to form.

  • Incorrect watering. Soil moisture must be constantly monitored. Do not allow the top layer to dry out. But remember that excessive moisture can harm peppers.

Treatment of diseases

Such damage to the culture can also appear due to various diseases.

Blackleg

The defeat starts from the stem. It will gradually darken and eventually die. If you saw the first signs of a black leg, then you must immediately water the affected plant with a solution of potassium permanganate. It’s also best to thin out the peppers.

The top layer of the earth at the same time should no longer be wet. After all, a humid environment will only contribute to the further development of the disease.

This disease is viral. It is caused by harmful bacteria.. In this case, small white tubercles will begin to form on the leaves, the fruits will be small and damaged. There will be no seeds inside.

It is impossible to cure such a disease, so the diseased vegetation can only be dug up and burned. Otherwise, the disease will spread to other cultures.

Fusarium wilt

In the early stages, Fusarium wilt is almost impossible to recognize. Over time, white spots form on the leaf plates, then they begin to deform, turn yellow, dry and fall off.

This disease is also not treatable. Infected bushes are carefully dug up and burned. To prevent damage, it is necessary to carefully process the seed material before planting.

Small white dots and pimples may appear on the leaves of sweet bell pepper due to the action of pests (aphids, spider mites, scale insects). They can form both from the outside and from the inside.

  • Trichodermin. This biological preparation perfectly copes with fungal diseases. It can be used both in greenhouses and outdoors. To prepare a working composition, you need to mix 1 liter of water with 10 grams of such a substance. The resulting solution is watered under the root. If a diluted liquid remains after processing, it can be sent for storage in a refrigerator. In this form, it can be stored for one month.

  • “Quadris SK”. The drug allows you to treat vegetation from fungal diseases. It is diluted in water (5 grams of the substance per 300 liters of liquid). Processing is best done either in the early morning or late evening. It is impossible to store the finished solution, it must be used immediately after preparation.

  • Alirin-B. This drug is biological. Before use, it is diluted in water according to the instructions. For 1 sq. m area accounts for 1 liter of the finished composition. The diluted liquid is poured onto the soil, and then it is all carefully dug up. Sometimes it is added directly to the holes during the planting process. There is one such tablet per 1 liter of water. Often, Alirin-B is also used for prevention.

Preventive measures

To prevent the leaves on the peppers from turning white, preventive procedures should be carried out in a timely manner. Remember to regularly remove all weeds from the site. It is in it that the causative agents of many diseases are located.

Before planting, planting material must be carefully processed. It is washed under cold water, kept in disinfectants and dried completely. Only in this form can seeds be planted in the ground. All garden equipment must also be treated with disinfectants. Transplantation should be carried out as carefully as possible so as not to damage the material.

In the process of planting, be sure to leave free space between rows and individual bushes (at least 10 cm). Landings should not be too dense. Otherwise, the peppers will not receive enough light and top dressing, which will also lead to infection.

Do not overwater the vegetation while watering.. Otherwise, due to waterlogging, harmful fungi will begin to develop, which are the causative agents of various diseases.

Regularly fertilize the soil so that each bush can get the nutrients that are needed for full growth and development. As a preventive measure, fungicide treatments can be carried out periodically. They prevent the appearance of viral infections on peppers.

To make the culture more resistant to diseases, it is necessary to carry out hardening. To do this, seedlings are exposed to open air for a couple of hours. This procedure is carried out several times, increasing the time each time. At the end, it is left for the whole night. Vegetation can only be placed in the shade, not in the sun.

Inspect peppers regularly for damage and pests. When they are detected, treatment should be started immediately.
