Sweet pepper is one of the vegetable crops that is suitable both for consumption raw and for preparing salads, main dishes, and for preservation. But in order to get a rich harvest, you must initially properly grow and prepare seedlings for open ground.
And during this period, you can encounter various troubles, since the culture is quite delicate and demanding of conditions. For example, most often farmers notice that strange white pimples appear on pepper seedlings. What causes this phenomenon and how to eliminate it - we will look at all the reasons in detail in this article.
The main factors that provoke such damage to seedlings are:
Each of the causes of damage to pepper seedlings in the form of pimples carries a certain threat.
With excess humidity and lack of light, the leaves begin to “swell” and pimples form on the pepper seedlings. All this ultimately leads to Oedema disease, or popularly called “dropsy of peppers.”
It is not difficult to distinguish this phenomenon - several leaves are covered with dense, watery-looking tubercles that look like warts or white mold.
At the same time, part of the root system dies off, and if the care of the seedlings is not adjusted in time, they may eventually die completely. If timely measures are taken, the situation can be corrected and the plants will recover.
This is a sucking arachnid insect. Of all the species of this pest, peppers are most often affected by one - Tetranychus urticae. It pierces the leaves and sucks the juice from them, and then weaves a web and lays its eggs in it. The larvae hatch within 25 days.
The first signs of infection are precisely the strange pimples on the pepper seedlings. If you don’t figure out the reason, then you will see how the foliage takes on a marble hue, some individual leaves are completely covered with cobwebs.
As a result of the activity of this pest on seedlings, plants die, since they do not yet have enough strength to fight. If the spider mite infects already adult individuals in the open ground, then this is fraught with a loss of more than half the harvest.
There are 2 types of pests here - the scale insect itself and the false scale insect. On the plant, both species look like brown-brown-yellow plaques or strange pimples. The danger of these pests is that they suck the juice from the leaves, depriving the plant of nutrients. The leaves eventually turn yellow, dry out, fall off, and the young and still fragile plants themselves die.
Important! It only takes a couple of hours for the larvae of a common scale insect to hatch from their eggs, so infection and damage to pepper seedlings occurs literally at lightning speed.
Aphids are another fast-growing pest that infests the surface of both stems and leaves. Like other insects, aphids feed on the sap of seedlings, very quickly rendering them completely unviable.
The measures that will be appropriate if pimples appear on the leaves of peppers depend on the specific cause. Therefore, deal with it first. Next, act according to the situation, focusing on the recommendations proposed below.
The simplest case in which it is enough to accurately organize the correct regime for maintaining seedlings.
What to do to remove pimples:
To combat spider mites, which have caused the appearance of strange pimples on pepper seedlings, different methods are suitable.
If everything is in order with watering and care, create conditions of high humidity for several days.
For this:
You can effectively get rid of this pest using special preparations.
The following tools help a lot:
Prepare solutions strictly according to the manufacturer's instructions. The procedure is carried out twice with an interval of a week. The foliage is sprayed on both sides.
Important! Please note that the mite can migrate, including to indoor plants. Therefore, place containers with seedlings at a remote distance or, better yet, in another room.
If the reason that pimples appear on the pepper leaves is aphids or scale insects, take immediate action. Start by manually cleaning the foliage to remove pests using an unnecessary toothbrush.
Also use special chemicals.
In this case, the following will be effective:
To avoid any more problems with pepper seedlings, either in the form of strange pimples or other signs of disease or plant death, follow the following preventive measures.
General rules:
Ready-made store-bought soil mixtures, which contain all the necessary substances, are excellent for growing pepper seedlings.
If you use land from your site, then:
Any disease does not arise out of nowhere.
Most often there are certain prerequisites for this, for example:
To prevent the appearance of pimples on the leaves after transplanting into open ground, you need to harden off pepper seedlings only when the leaves become sufficiently dense and elastic. Otherwise, the result may be the opposite: all the seedlings will die.
Rules of procedure:
The root system of peppers is very delicate, so picking is done extremely carefully, adhering to the following recommendations:
Attentive attitude to seedlings and ensuring normal conditions for their development is the key to a good harvest in the future. Therefore, do not ignore the necessary care measures and react promptly if pimples or other damage suddenly appear on the leaves of peppers.
Why do pimples appear on pepper seedlings? Is it a disease, improper care or pests? How will the pepper seedlings behave later? Will the presence of pimples affect the quality of the fruit?
Pimples appeared on pepper seedlings
Each pepper seedling has its own characteristics, and pimples are no exception. But it is possible to determine what it is. If the pimples are brown and remain in place the entire time you observe them, then the seedlings have been affected scale insect. If scale insects are present, they may also be green or cream in color.
Viral diseases of pepper seedlings
Viral diseases of pepper seedlings are activated in an unfavorable environment. For example, pepper is located at low air temperatures and high humid air. There may be another option: too moist soil, dim lighting. Correct problems in care, water in moderate portions and regularly, monitor how the pepper seedlings behave. If the problem gradually begins to disappear, then after some time you can expect its complete disappearance. In the future, continue proper care and you will not lose your crops.
It also happens that the pepper does not want to recover. If the problem is definitely a viral or, perhaps, bacterial disease, then you need to cut off the damaged areas - leaves, shoots, roots - treat them with biological preparations, close the wounds with wood ash powder.

Back in February, the hardworking summer resident is preparing for the summer season. With love, he buys the best soil for seedlings, takes out his seeds from the bins or buys elite varieties, plants the seeds and rejoices at the appearance of shoots and the first leaves. And when the peppers that have sprouted together have grown a little and begin to hurt, this greatly upsets the summer resident, who has invested love and the best expectations from a rich harvest. Having encountered a seedling disease for the first time, he begins to look for clues on the Internet, posting photographs and describing the problem.
Pimples on peppers can appear for various reasons.
There are often cries for help regarding pimples on young pepper leaves. If pimples appear on the leaves of your pepper seedlings, there may be different reasons, we will try to help you and consider different options. To avoid or minimize seedling diseases, preventive measures are necessary. All nightshade peppers, tomatoes, and eggplants are susceptible to the same diseases. Agronomists recommend not to neglect crop rotation, not to plant nightshades in the same place for up to 3 years, taking breaks.
Before you start growing healthy and strong seedlings, you need to carefully prepare the ground for planting seeds. If you take your own land, take it not after the nightshades, but it is advisable that onions or garlic or carrots grow on it before that. And after harvesting, ideally, green manures (mustard, rye, rapeseed, etc.) were also sown, which enrich the soil with nitrogen and improve its quality. But even in this case, it is better to prepare the soil for planting by adding compost or rotted manure, sand for looseness, whatever the specific crop requires.
Pepper loves the addition of peat and wood ash. It is necessary to disinfect the land from diseases.
If the soil was bought in the best stores and it is beautifully written there how it is saturated with microelements and useful substances, taken from the best points on planet Earth from under the most melted glaciers and so on, you can believe it, but it is better to steam and disinfect this valuable soil. Often it is packaged when changing soil in greenhouses and the soil, in addition to added fertilizers, is full of a bunch of diseases. How to steam the soil correctly?
There are several methods; in country conditions you can steam it in a water bath for half an hour; at home, it is recommended to heat it in an oven no higher than 70 degrees for half an hour. You can use freezing in winter by exposing the soil to low temperatures, or pour the soil for seedlings well with a hot solution of potassium permanganate until it evaporates completely.
Store-bought soil should be steamed in a water bath.
Seedling diseases do not come from nowhere. Their suppliers are contaminated soil and seeds. If you want to avoid the questions “what are those pimples on the leaves of my pepper?” - take preventive measures. This will significantly reduce the risk of disease and bring the desired harvest closer. Seeds, either your own or purchased, must be disinfected, or, as experienced gardeners say, “etched.” How to do it? To disinfect seeds, it is recommended to immerse them in a weak solution of potassium permanganate for 30-40 minutes.
You can disinfect with ready-made, low-toxic means: “Baktofit”, “Albit” or a solution of ash in the ratio of 1 liter of water to 2 tablespoons of wood ash. Place the seeds in the solution for 5 hours in a gauze bag. If you follow these simple manipulations, the risk of getting pepper seedling diseases will be minimal. But if the disease already exists and the information is late, we will look into it.
Baktofit effectively destroys fungi and bacteria
What are these pimples on the leaves of tender pepper seedlings? Let's consider the options. The most harmless of the options is that you overwater your seedlings and there is not enough light for them. In such a situation, swelling of the leaves occurs, Oedema. This problem is more common in greenhouses; you need to reduce watering and reduce humidity by ventilation. At home, it is enough to change the conditions, reduce watering and change the place to a sunnier one, and the problem will disappear.
Another cause with similar symptoms of the disease is spider mites. First, “pimples” appear on the pepper leaves, similar to white bubbles, then the spread intensifies, and cobwebs appear. The mite is destructive to seedlings. One of the methods to combat it is to create conditions of high humidity in which the tick dies. Water the plant generously and cover with polyethylene for 3 days. Make sure that the pepper itself is not damaged or burned in this shake from the high temperatures of the “greenhouse”.
Of the ready-made chemical preparations suitable for tick control:
When moisturizing spraying, carry out the procedure in the morning or evening, otherwise droplets of water can burn the pepper leaves with the help of the sun and you will puzzle over the cause of new, burnt spots.
Spider mites on pepper leaves
Aphids, scale insects, and false scale insects can cause tubercles or pimples on the foliage of young peppers. These pests can move from indoor plants even if you have prepared the soil and seeds. Aphids and scale insects are characterized by the appearance of honeydew secreted by them - a sticky liquid on the leaf. The false scale insect does not secrete such a secretion, and it can only be distinguished by easily separating it from the shell. How to protect a plant from these pests? A soap-ammonia solution works effectively. Add 20 grams of liquid soap and ammonia to 2 liters of water and treat the plant.
Of the ready-made chemical preparations, the following are effective:
The scale insect itself must be cleaned off manually, using a toothbrush or a cloth moistened with an alcohol (soap) solution. After removing the pest, it is necessary to treat it with Aktelik and Fosbecid solutions. The use of neem oil is recommended, promising a good effect against pests.
It is not necessary to harden off pepper seedlings until the leaves become dense, as they are extremely sensitive to strong drops in temperature. It is enough for the temperature to drop to + 12, and the young leaves will instantly wither and eventually die. It should be remembered that any seedlings will grow slower in the cold. You can only take the plant out into a closed balcony and in sunny weather. To prevent the soil from drying out, it is necessary to ensure regular watering and spraying.
You can only harden off strong and well-formed pepper seedlings.
You can’t be protected from all diseases, but forewarned means forearmed. For a gardener, you need to know preventative measures, methods of control and get a good harvest of pepper through labor.
Avoid epidemics in your garden, and if this happens, try to provide the necessary assistance to your plants in a timely manner.
