In fact, unlike other vegetables, pepper is considered to be very resistant to harmful insects and all kinds of diseases. However, sometimes such a vegetable is damaged by various diseases. Peppers and insect pests are often attacked. The most common lesion among all varieties of peppers is, of course, rot. It can be present not only on leaves or other plant elements, but also on fruits

Unfortunately, some diseases and pests of pepper not only negatively affect the yield of the crop, but destroy the vegetable completely. This is the main reason for observing the implementation of preventive measures and agrotechnical standards.

Aphids are also dangerous for pepper. These pests gather in whole flocks around the entire perimeter of the plant, feeding on the liquid secreted by the pepper. As a result, the yield indicators become twice, or even three times lower. Also, the development of pepper is very slow. But this is not a complete list of those factors that can harm a healthy and tasty vegetable.

Blackleg

Black leg is the type of disease in which damage can be seen in the lower region of the stem of the bush in a young crop seedling. As a result, if you do not take action, the pepper will die. Excessive humidity or a sharp cold snap can provoke the appearance of a black leg. Also, a negative factor that creates favorable conditions for the development of this disease is dense sowing of seeds to obtain pepper seedlings. As a means to combat blackleg, it is required to pickle seeds for planting pepper with a manganese solution. The procedure should be carried out within twenty minutes. Those bushes, which have managed to hit the disease, must be destroyed, and then shed the soil with copper sulfate, or a chemical called "Tiovit Jet". For spraying seedlings, they usually choose "Phytodoctor" or "Trichodermin".

Verticellosis

Verticillosis is a disease caused by fungi in the soil. They seep into the plant itself through even small wounds in the area of the root system. It is customary to distinguish between three types of such trouble:

- Brown verticillus may occur in early July. At this point, the growth of the pepper bush slows down, and the leaves are prone to the appearance of dark spots on themselves. After a short period of time, the leaves dry out, and the plant soon dies.

- dwarf verticillosis can appear only in the first month after sowing pepper. As a result, slow growth of bushes and low yield rates will be seen. Damaged leaves and ovaries crumble soon after the onset of the disease. Of course, if you water the pepper correctly and in a timely manner, then it may remain and not die until the end of the season, but, in principle, this is already pointless.

- green verticillus often appears together with brown disease. When it acts on a plant, even a very developed vegetable crop begins to abruptly lose leaves, and after several days it dries up completely.

As a means of combating pepper wilting, it is necessary to promptly eliminate plant residues in the ground at the end of each season. And even before planting, preference should be given to those varieties of pepper that are resistant to this disease (fortunately, there are many of them).

Phytoplasmosis

Phytoplasmosis is the appearance of rot on the root system. As a result, the growth of the bush begins to slow down, after which it may generally remain dwarf in size. It is not uncommon for pepper bushes to get yellow at all. The leaves here will also signal the disease with their compaction, reduction in size and curling. The vegetables themselves also become small and brittle. The taste of the fruit is also lost. Affected crops wither very quickly. The main time when there is a danger of damage to the culture by phytoplasmosis is the end of May. It is then that leafhoppers appear, which carry the disease. Therefore, in order to avoid the formation of such a disease, pepper should be sprayed with insecticides after planting at the time of the appearance of insects. Each spraying is carried out twenty-one days after the previous one.

Late blight

Late blight can appear on any element of the pepper bush. It's easy to spot him. It represents the formation of brown spots, which are surrounded by a border along their contour. In the hot season, the plant can dry out, and in wet weather it can simply rot. To avoid the appearance of this disease, you should pickle pepper seeds in a manganese solution (1%). The procedure should take about twenty minutes. At the first symptoms, you need to spray the pepper with Bordeaux liquid. If flowering has not yet begun, then you can use the preparations "Oxyhom" or "Phytodoctor". More serious remedies are needed with abundant damage to plants.
