Why do peppers darken leaves and how to treat them?

Fungal and bacterial viruses infect absolutely all cultures, including pepper. One of the main symptoms is blackening of the leaves.As soon as the gardener noticed dark brown spots, the main task is to find out why they appeared, and what was the reason before starting to solve the problem.

There are several reasons why there may be blackening on the foliage and streaks on the foliage of a vegetable:

• care of the plant is carried out incorrectly;
• irrigation is less frequent;
• temperature conditions are not observed;
• bushes damaged by pests or microorganisms;
• humidity in the air above normal;
• there is no additional feeding.

Pepper reacts strongly enough to changes in temperature, and this applies not only to open ground, but also to the greenhouse. Comfortable temperature starts at 20 degrees, which is why you shouldn't plant seedlings in open ground too early. Inside the greenhouse, you must install a thermometer and monitor the microclimate. There are varieties that are particularly sensitive to cooling.

As for the fertility of the soil used, the pepper needs:

• nitrogen;
• phosphorus;
• potassium;
• iron.

The lack of these elements is also the cause of blackening on the foliage. If watering is provided normally, there are no diseases, the air temperature is normal, then it's time to make additional additives in the soil.

Another cause of blackness is the spider mite, which most often appears in greenhouses and greenhouses, and not in open beds, because it loves heat and dampness.

Such a disease, as late blight affects not only the pepper - the bacteria spread by airborne droplets and are contained in the soil. If you use contaminated land for planting, the pepper will hurt, black spots will appear on the stem, leaves and even fruits. As a rule, infection occurs in mid-summer, and often the cause becomes:

• decrease in air temperature at night;
• use of cold water when watering;
• numerous precipitations;
• too thick landing.

There is another disease characterized by the appearance of the same signs - black spot. Black dots on the foliage with a yellow edge indicates the appearance of a problem. Most often affects plants after transplantation or damage to the stems. You can meet the disease usually in greenhouses, and not so often in the garden. High temperature and humidity are ideal conditions for the development of the disease. The saddest thing is that this disease is not treatable, all plants must be immediately destroyed.

At the early stage of late blight can be removed if you use "Hom", "Skor" and other drugs. Fungicides work best with this problem, in addition, it is perfect for processing Bulgarian pepper 1% Bordeaux liquid.

Chlorinated copper oxide can be used for treatment, 40 grams of which must be dissolved in 10 liters of water. All the tools must be processed then with manganese. If possible, in the presence of diseases of this nature, professional gardeners are advised to remove the affected plants.

As for the spider mite, in specialized stores there are many drugs that are used to solve the problem. On the package there is a detailed manufacturer's instructions.

Many housewives independently prepare solutions for processing, for this you can use regular laundry soap. One piece is enough for 10 liters of water. The resulting mixture was washed leaves of plants.

You can use pure medical alcohol, which in no case can not be diluted with water, because in this case, the plant will burn. A good tool - decoction henbane, which is collected at the time of flowering.Ten liters is enough for three kilograms of the plant, which should cook for at least three hours.

The simplest, but quite effective method is an infusion of garlic. For three liters of water it needs 500 grams. Infused solution for five days in a dark place, but in its pure form it is not used. To do this, 60 ml of it diluted in 10 liters of water and add 50 grams of soap.

Prevention allows you to avoid the appearance of black spots on the leaves of pepper, it significantly reduces the time spent on caring for plants. The main preventive measures are:

• seed treatment, which must be soaked in manganese solution for several hours before planting;
• disinfection of the soil used - it can be roasted in the oven for an hour, if we are talking about growing seedlings;
• cultivation of land with boiling water before planting plants;
• replacement of topsoil, if the ground is infected with viruses;
• soil acidity tracking;
• crop rotation - peppers are not planted in the same place next year; you can also not plant vegetables after potatoes, tomatoes and blue ones;
• tracking of humidity and temperature conditions in the greenhouse;
• regular and timely airing of the greenhouse.

Observing the simple rules of pepper care will avoid many problems and preserve the harvest until autumn. Prevention - the best tool that facilitates the work of the gardener. Even if you manage to cure pepper, it will not give a normal crop, therefore, they give more time to prevention. Moreover, some diseases can not be treated, and you can lose all the plants, even if you do everything right.

Fungal infections breed very well in acidic soil, which is why you should use ash or dolomite flour before planting. Never violate the laws of crop rotation and watch the roots of plants, they must have enough space for development and be fully submerged.
