Pepper Disease: Treatments

It is quite difficult to grow bell peppers or pungent hot. A vegetable loves heat, a lot of sun and requires compliance with agricultural technology. To get a good harvest and healthy fruits, you need to work hard, because a young vegetable is often threatened by various viruses and infections. Pepper diseases are the main thing to start treating in time, since the plant can die.

Pepper disease

Causes of the appearance of diseases in a vegetable

Peppers are most vulnerable in cloudy and rainy summers. First, the gardener must determine the cause of the disease in pepper. Diseases of peppers appear not only due to the local climate and weather conditions. Often, pepper diseases arise from improper care and vegetable growing conditions.

Various infections, fungi and viruses almost always infect a young plant at the initial stage of cultivation. It should be understood that treatment does not always produce the desired result and, most often, the vegetable crop dies. But, if the gardener sees the disease in time and knows how to treat it, it may be possible to save the crop.

Bacterial diseases

If peppers grow in a greenhouse, then this environment is ideal for the birth of bacteria. The infection grows faster in the greenhouse than in the open ground, so it is recommended to fulfill some conditions and try to prevent the disease from growing in vegetables. Timely recognition of the disease eliminates long-term treatment and will save most of the crop.


Phytoplasmosis disease appears due to the presence of mycoplasmas on the fruit. Infection spreads quickly if pests such as aphids or ticks are present. The presence of infection stops the growth and development of the fetus.

They treat the disease by spraying with drugs such as Barrier and Barrier. Tools are diluted in proportion to 10 liters of water 3 tbsp. l facilities. Oxychom is used before the plant begins to bloom, in the ratio of 2 tablets per 10 liters of water.


A disease such as a columnar forms small twisted-shaped fruits that ripen early enough than expected, after which a sweet vegetable variety has a bitter taste and no juiciness. The leaves of the plant begin to hurt and become yellow.

The gardener needs to be prevented, which will save vegetables from diseases:

  • prepare seeds before planting in pots;
  • it is better to plant hybrid varieties, they are resistant to many diseases.

If preventive measures have not helped, begin to treat seedlings. For this, drugs such as Actara and Confidor are used. The drug is used in a ratio of 1 liter of water, 700 g of the product. It is also worth remembering that if a diseased bush is discovered, it is urgently torn out and burned. The site is occasionally harvested from weeds and dried tops.

Wither Verticillin

Leaf wilting is due to the presence of bacteria. The leaves begin to acquire a pale shade, it becomes rough and hard. The size of the fruit is small, the shape is twisted, and there are practically no seeds inside.

This disease is not treated. But, if preventive measures are taken, there are chances to protect oneself. It is necessary to process seeds and the soil well before planting. For this, 0.1 g of foundationazol per 10 g of seeds is used.

Black spotting

It’s worth taking care of neighboring peppers.

If the leaves began to turn black, then the peppers were attacked by black spotting. The cause of the disease are bacteria that are in the seeds. Bacteria grow if the weather is hot enough and humidity is high. Foliage takes on dark spots. When the pepper disease progresses, the spots increase and turn black.

It is impossible to cure black spotting, therefore, preventive measures must be taken, therefore, it is always necessary to decontaminate planting material before planting. For this, such drugs are used: Planriz, Fitosporin, Trisodium phosphate.

Means treat the seeds in a ratio of 10 ml per 1 kg of seeds or spray 10-20 ml per 1 liter of water.

Viral diseases

Viral diseases are very dangerous for the crop. It is necessary to deal with them at first. The disease is directly dependent on the cells of the culture. If there are no affected plants, then the virus will not be able to spread.

The first signs of disease indicate that the vegetable crop is not able to provide the fruits with calcium. At the first stages of development, the disease affects the base of the vegetable. Green spots appear, which gradually turn brown. An area with a diseased plant dries quickly.


Bronze is a spotted wilting. The disease can be easily recognized - the foliage of the plant becomes purple or bronze. If the virus is in the penultimate stage, brown spots or streaks appear. They form in the center, moving smoothly to the edges.

Treatment is carried out with the help of the drug Fundazole. They are also treated with seeds before sowing. To prepare the mixture, take 1 g of the drug, dilute it with water in a small amount. Constantly mix and add a volume of water up to 1 liter. In addition, the entire number of healthy fruits is plucked, and watering is no longer carried out.

Tobacco mosaic

Tobacco mosaic is a very serious disease. She is able to completely kill the entire crop or reduce it in quantity. A marble pattern is formed on the foliage, with a yellow and green tint. The leaves gradually curl, growth stops, and the fruits grow small. Also, brown spots may be noticeable on the fruits.

To prevent pepper disease, the seeds are processed before planting. If the disease appears, it will be impossible to cure it.

  1. For prevention, only healthy seed varieties are taken.
  2. Seeds need to be soaked in a solution of potassium permanganate for 30 minutes. After processing, they will become stable and will hurt less.
  3. When the seedlings are planted, it is watered with the same solution every 21 days.
  4. The bush is sprayed with milk and water in proportions of 1:10 and add 3-4 drops of iodine. After that, pepper is covered with a film.

Vertex rot

Many different pests

They treat a vegetable by destroying diseased fruits. They also spray with a solution of milk of lime or 0.3-0.4% calcium chloride.

Fungal diseases

Fungal diseases in peppers cause great damage to the crop. In order to prevent disease, you need to know the symptoms and possible manifestation factors.

Late blight

Blight virus flies through the air and settles in the ground. Fungus severely damages foliage. Small brown spots form on it. But soon they begin to rapidly increase in size, walking around all the foliage and fruits.

The fight against fungus consists of spraying with Bordeaux fluid. To prepare the product, take 3 packets of copper sulfate and the same amount of lime per 10 liters of water.


If the stem has acquired a dark color, it means that it is attacked by a fungus. The black leg likes to attack a young plant, but it is possible that it will affect an adult. The fungus enters the bush from the ground or through diseased seeds. The description confirms that the black leg appears due to close planting of seedlings or from poor ventilation in the greenhouse. The soil dries, rots, and eventually the seedling dies.

The fight against a disease such as a black leg consists of removing diseased bushes, while healthy ones are treated with vitriol at a 3% concentration.


You can fight rot

Alternariosis is also a fungal disease found in peppers. The fungus affects the stem and roots of the plant. Fungus appears due to dry climate. At the very beginning, brown spots appear on the leaves. Soon, the fungus passes to the fruit. On the fruits, you can see areas similar to a white fluff, which after a while becomes black.

The fight against rot on a vegetable crop occurs with the help of Bordeaux liquid, in a ratio of 10 liters of water, 3 packets of copper sulfate and lime. You can also use any drug that contains copper.


When pepper grows in a greenhouse, it often undergoes a disease such as cladosporiosis. It is quite difficult to detect the ailment, the leaves begin to darken a little and become covered with mold. The fruits stop in development and fall off.

You can avoid the appearance of the fungus if from time to time thinning the bushes. Also, the landing should be free. When the first symptoms of the disease began to appear, it is necessary to spray the bushes with 3% copper sulfate or infusion of garlic. To cook it, you will need 200 g of garlic and 1 liter of water. Garlic is cut into small slices and poured with water. It is necessary to withstand the infusion for 5 days and strain.

Gray rot

Gray rot is formed due to the fungus, and the fungus, in turn, acts due to increased air humidity. Rot first forms on the lower shoots in the form of brown spots. Then it passes completely to the whole plant, and the spots turn black. If treatment is not started, the mold completely covers the bush of pepper.

It is possible to cure rot and prevent its appearance if the following conditions are observed:

  • observe the distance at the time of landing;
  • control of the degree of heat and humidity;
  • removal of diseased fetuses;
  • treatment of diseased areas in the garden with a solution of lime and fungicide in a ratio of 1: 1. Also, the composition can be changed to fine charcoal or ash.


When the weather does not meet the requirements of the culture, the vegetable is destroyed by streptoriasis. White spots of different sizes form on the foliage. The fungus basically catches up if the plant is weak enough. The gardener must monitor the application of fertilizing, the correct light and humidity of the earth. The sick bush must be removed from the site immediately. The remaining bushes are treated with agents that include copper, and after 2 weeks, repeat spraying.

Greenhouse - a great place for the appearance of fungal diseases. Many fungal diseases can be cured, but it is better to prevent the disease than to treat it for a long time.


Diseases of the pepper and the fight against them is a rather difficult and lengthy process. Infections often appear on young plants, as they are still weak and have not yet fully regained their strength. It doesn’t matter where the vegetable grows - in the garden, in the greenhouse or at home - the virus can overtake everywhere. Therefore, it is important that the gardener carry out prophylaxis and pay as much attention as possible to the young vegetable culture.
