Why do pimples appear on pepper leaves

The appearance of the leaves is the main indicator of the health status of the plant, instantly revealing the presence of infections, pests or errors in care. Pimples on pepper leaves occur quite often. They can be caused by various reasons, from completely harmless to landing leading to death.

Causes of pimples on the leaves of pepper

Causes of formation and symptoms

Tubercles on leaf blades occur due to the presence of one of the following problems:

• odema (swelling of the leaves);
• scutellum or aphid;
• thrips;
• spider mite .

To correctly determine the source of tubercle formation, it is necessary to carefully examine the affected leaf plate with a magnifier. Moving pimples indicate the presence of aphids, motionless brown (less often – green or cream) – scale insects. White or greenish tubercles, similar to warts, are a symptom of leaf swelling. White bubbles and cobwebs are formed when infected with a spider mite, and clarified spots on the stems and leaf plates – when infected with thrips.

In addition to the color characteristics of the tubercles, each type of leaf lesion has a number of other symptoms.From them you can understand what the problems are associated with.

Odema

The reason for the physiological edema is a malfunction at the cellular level, due to which the fluid does not have time to be absorbed by the leaves and stagnates in the form of tubercles. This process can be triggered by such factors:

• excess moisture in the soil;
• hypothermia of the root system;
• lack of sunlight or additional light;
• high humidity;
• stress due to a sharp change in temperature and light conditions;
• too sprouted plantings of sprouts to each other.

When odema, green or white tubercles look like watery capsules, tight to the touch. If too many such pimples form on the leaf blades, the leaves turn yellow and fall off.

Scutellaria and aphids

It is easy to detect aphids

The main sign of damage by these pests is the presence on the foliage of a sticky substance (paddy) produced during the life of insects. The seedlings can become infected from the soil or due to the proximity to already diseased crops.

Symptoms of aphid or scabby pepper damage:

• stunting under proper care conditions;
• curling and yellowing of leaf blades;
• slowing growth of sprouts;
• the presence of a paddy;
• a large number of larvae and adult insects on the inner side of the leaf.

Thrips

The main external sign of pepper damage by these insects is clarified spots, which eventually merge into one. For a year, several generations of pests are formed at once. Thrips-infected seedlings quickly weaken and die without proper care.

Thrips are masked on the sheet, located on its back side. Without a special examination, it is extremely difficult to notice a defeat by these insects at an early stage, but the larger the population, the easier it will be to determine the infection by the yellow color and openwork of leaf plates.

Spider mite

Spider mites mainly live on the bottom of leaf blades, occupying the entire plant as they become infected. Adult individuals (10-20 days from the time of egg laying) migrate very quickly from one shrub to another, capturing the entire planting area.

Tubercles, when infected with a spider mite, are located on the lower side of the leaves, and a thin spider web braids parts of the bush. At the extreme stage of damage, the plant can be completely covered with cobwebs. Keep in mind that these pests are carriers of a large number of serious viral infections and fungal diseases that are dangerous to plant life.

Control Methods

Pimples on pepper seedlings can be a messenger of serious problems and even death of the plant. Especially important is the timely intervention and the implementation of a set of measures aimed at improving the culture.

The choice of effective methods of control depends entirely on the causes of the pimples. It is also important to consider the general condition of the plant. Sometimes pests have to be removed manually.

Actions for leaf swelling

It is important for plants to create favorable conditions

Swelling of the leaves is not a disease, therefore, it does not require treatment, but the following measures should be taken to alleviate the state of seedlings:

• limit the amount of irrigation;
• maintain optimal air temperature (about 20 ° C);
• organize drainage holes in containers with seedlings to remove excess moisture;
• extend the duration of daylight hours by connecting daylight bulbs;
• temporarily discontinue fertilizer application;
• control the acidity of the soil;
• distribute the bushes seedlings so that there is sufficient air circulation and all the sprouts get access to the light.

The complex of these actions helps to avoid the formation of pimples in the future if they were caused by adverse environmental conditions.

Actions when infected with pests

If the pimples on the leaves of the seedlings of the pepper appeared due to harmful insects, it is necessary to quickly carry out a set of measures to combat them:

• Chemical measures – treatment of plants with synthetic insecticides (drugs for the destruction of insect pests). This is the most effective method, potentially dangerous to human health, it requires additional safety measures.
• Physical measures – washing off with soapy water or alcohol or killing insects manually.
• Biological measures – use against pests of their biological enemies (insects and birds) or the use of microbiological preparations.
• Natural insecticides – folk recipes, tinctures and decoctions (based on garlic, onions, pepper, tobacco, laundry soap, ash, wormwood, ground red pepper, kero ins, ammonia and others.).

In the treatment plant should take into account the individual characteristics of each species of insect. For example, trixes are extremely resistant to any control measures and require at least 2 treatments in one season (using several drugs at the same time). It is much easier to get rid of the spider mite: it is enough to water the seedlings abundantly and put on a plastic bag for a couple of days, because these insects are extremely poor in humidity.

A decrease in the population of insect pests also contributes to a change in external conditions: the introduction of moderate watering, frequent ventilation, isolation of infected plants. The success of the fight depends not only on the use of the right means, but also on when it was started.

Prevention of pimple formation

Problems associated with the formation of tubercles during cultivation of pepper seedlings can be avoided by methodically conducting a set of preventive measures. They include:

• seed disinfection (potassium permanganate solution, ash, Bactofit or Albit);
• thorough loosening and mulching of the soil;
• prophylactic use of insecticides or folk remedies (twice a season);
• development and use of an optimal watering and humidification system;
• regulation of plant access to light, use of additional lighting sources;
• use of land with a good drainage system (drainage should occupy at least a quarter of the pot);
• regular inspection asthenia for pest detection (special attention is paid to the underside of leaf blades).

The systematic implementation of preventive measures helps prevent and detect infection of sprouts at an early stage, which greatly increases the chances of recovery.

Conclusion

Tubercles on the leaves are a common sign of unhealthy seedlings. Plant pests can cause pimples to appear either breeding conditions. Timely measures taken can save pepper seedlings and contribute to the formation and maturation of a rich harvest.

These problems are often encountered by beginner growers. Adhering to the recommendations for care, they can be run away.
