As practice shows, cucumbers grow very quickly. For this reason, many gardeners sow seeds directly into open ground. However, the seedling method allows you to enjoy ripe crispy fruits earlier. We will talk about the problems that may arise when growing seedlings in this article.
The most common diseases of cucumber seedlings
Often seedlings are attacked by various infections, as well as bacteria and viruses. It is important for each gardener to be able to distinguish between this or that infection, because if the seedlings suffer, for example, from the cucumber mosaic virus, then it must be immediately destroyed. Diseases such as sunburn of the leaves respond well to treatment.
Root or root rot
Sometimes fungi can infect the root system of seedlings. If you pull the bush out of the ground, you will notice that the root has become rotten and dark. The aerial part of the bush does not manifest itself until a certain time, but over time, without receiving normal nutrition, the bush turns yellow and fades. The main cause of the disease is high humidity, in which fungi and bacteria feel great.
white rot
This is a disease of the aerial parts of seedlings. Bacteria are found in the soil, but at low temperatures and high humidity, they are safely activated. We can assume that the main cause of infection is low temperature and excessive watering of the substrate with cold water. If the plant is covered with white bloom, and after a while the affected area becomes soft or even wet, it can be assumed that it is attacked by white rot.
Gray rot
A similar disease of a fungal nature. How to recognize the disease? Plants affected by gray rot are covered with a gray putrefactive coating, which gradually spreads to the entire bush. The main causes of the disease: sharp fluctuations in temperature, excess nitrogen in the soil, waterlogging of the soil. If the distance between seedlings is small, then the disease quickly spreads to neighboring bushes.
Ascochitosis
Black stem rot, in the people this disease is called stem cancer. The most favorable environment for the disease is humidity and increased heat, so if the seedlings are on the windowsill under direct rays of light, then they are at risk. Symptoms of the disease: gray spots on the stem, black dots throughout the bush.
Anthracnose
Folkly copperhead. The disease affects not only cucumbers, but also the pumpkin family. The infection may be contained in the seeds. The temperature does not affect the pathogen, so the disease occurs both when the seedlings are supercooled and when they are well heated.
So, in order to exclude diseases of seedlings of cucumbers, proper care of plants is important, it is not necessary to allow waterlogging of the soil.
