Pests of peppers in a greenhouse: general information and methods of destruction


Diseases and pests of greenhouse pepper cause significant yield damage. The most common pests of peppers are aphids, spider mites and bare slugs. Diseases have a rather strong effect on pepper in a greenhouse, including a columnar, a black leg, a fusarium lesion, late blight, leaf bronze and cladosporiosis.

General: who makes holes in the leaves

If caterpillars, wilting plants or other diseases of peppers are found in the greenhouse, the gardener must immediately take measures to destroy them. Pest and disease control is very difficult if treatment is not started on time.

Depending on the form of the disease, pest control and treatment can be of a different nature. Very often, gardeners do not imagine which insect pest struck their plants in the greenhouse, and are guided only by a photo, comparing the picture of the defeat of peppers with already known symptoms.

Most often, one can observe holes on the surface of leaves, partial or complete withering of the plant, as well as the general picture of oppression of peppers in the greenhouse. If it was not possible to determine the cause of the disease from the photo, then it is worth paying attention to the main signs characteristic of certain types of pests.

Signs of pests in the greenhouse

If peppers in the greenhouse, including their leaves and fruits, stop growing, the gardener may suspect damage to plants by pests or diseases. Very often wilting and falling of leaves is observed. Some pests, such as caterpillars, are able to completely eat the green mass of plants.

In addition to caterpillars, adult aphids and their larvae feed on leaves. Such insect pests are perfectly distinguishable by visual inspection, and it is not difficult to compare the photo with the detected insects. Most often you can find only the most common pests in our climate.

Description and photo of caterpillar species and damage

Greenhouse conditions are very favorable for the life of some types of pests that affect peppers. If there is a suspicion of the settlement of adult pests or their larvae in the greenhouse, then it is necessary to identify the type of pest from the photo or description and proceed to the treatment of plants. A significant part of the pests eats the green mass of plants. Do not forget that many pests weaken the plants without causing their death, which can cause quite serious diseases.

Pepper: Pest Control

The defeat of gourds

These pests settle on plant leaves, flowers, and also the stem. Adult aphids eat almost all the aerial parts of the plant, and their larvae suck out the juices, which causes very fast withering. If these small pests appeared in the greenhouse, then most often their presence is detected too late, when the pepper leaves are almost completely eaten, and their fruits dry and fall. The result of the disease is very often complete death.

Spider mite affection

If a cobweb suddenly appeared in the greenhouse, then it is worth examining the plants to defeat them with small, but very dangerous pests, which is called the spider mite. This parasite does not eat the green mass of plants, but draws juices from pepper leaves in the greenhouse, which causes them to wither. Massive damage does not allow plants to develop and causes rapid death.

If this particular insect is found, then you should tune in to a fairly long struggle and the use of serious chemical agents.

Slug

A very common pest that eats leaves and fruits of pepper, causing damage and decay. Adult slug eats a lot and if you do not notice the pest's settlement in the greenhouse in time, then you can completely remain without a crop. A plant without leaves ceases to develop and bear fruit.

Wireworm

Noticing this pest is very difficult. The wireworm is the larval stage of the nutcracker. The malicious larva has a tan color and hard integument. The larva eats the root system of pepper, and if the plant in the greenhouse begins to wilt, then it is worth suspecting the presence of this particular parasite. If the wireworm eats pepper roots too actively, the plant will die.

There are other pests, most of which eat leaves and fruits of pepper or eat plant juice. One of them is the Colorado potato beetle, which eats leaves and stalks of pepper in large quantities. It is very easy to distinguish it from other pests due to the bright and characteristic color. Most gardeners easily find its presence in the greenhouse.

Sometimes it can be difficult to determine who eats the green mass of plants, but in any case, a thorough examination of the plants and the start of measures to destroy them are required.

Pest control measures

The regimen of the use of drugs and the duration of treatment are selected by gardeners depending on the type of pest, as well as its quantity and the stage of the defeat of peppers in the greenhouse.

Fighting gourds

You can get rid of aphids quickly and effectively by using abundant watering of pepper in a greenhouse with a liquid type of fertilizer based on nettle. Such irrigation should be carried out for several days in a row. In addition to the destruction of pests, such a tool has a very beneficial effect on the growth and fruiting of plants.

A good option is to use the drug known to most gardeners "Karbofos" or Keltan. At the moment, several fairly strong and effective chemicals against aphids are produced.

Fight against spider mites

Destroying a spider mite is very difficult. Such a pest very quickly adapts to any drugs and develops a strong immunity against chemicals. Despite the fact that manufacturers of plant protection products against pests regularly release new chemicals, single treatments are not able to completely destroy this pest.

The most effective means show:

  • Actellic
  • "Fosbezid";
  • "Fufanon";
  • "Karbofos".

Slug fighting

Slugs are pests that are easy to deal with. Grooves are made along the greenhouse ridges, which are systematically shed with lime mortar. Pepper bushes are watered very carefully. The Arrow drug works well, which very quickly destroys the pest.

Wirewalking

Most often, gardeners resort to the use of sufficiently strong drugs, such as a highly toxic agent Bazudin or "Diazinon". Chemical products have proven themselves very well. Stormbreaker 2 and Medvedox-U, and "Calypso". Granules can also be placed in the greenhouse. Provotoxthat fit into the holes dug next to the bushes of pepper.

The fight against the Colorado potato beetle

Despite the fact that it is now very popular to use powerful and modern tools, it is easier for many gardeners to manually collect this pest. All adult beetles and larvae are easily eliminated from the leaves of plants, and then destroyed.

Preventative measures

As a preventive measure, it is necessary to regularly perform loosening of the earth in the greenhouse, as well as spraying peppers with ash infusions with soap or a solution based on garlic. All plant residues formed as a result of weeding must be removed from the greenhouse, and in the autumn period, competent disinfection of the earth and all parts of the greenhouse should be carried out.

How to get rid of pests of peppers folk methods

The use of chemicals should be classified as "heavy artillery". It is much more important to prevent the development of the disease than to treat it. Moreover, any chemical constituents can negatively affect the quality of the crop and the health of gardeners.
