In order for the cucumbers to please the summer resident with a good harvest, it is necessary to have some knowledge in the field of the agrotechnical features of this vegetable crop and the diseases that the plant is susceptible to, because many of them can not only harm, but completely destroy tasty fruits from the beds

Various diseases can overtake cucumber bushes at different vegetative stages, due to which there is a classification of them into three main groups. These include diseases of the fungal, bacterial and viral type.

In the field of fungal diseases, powdery mildew is especially common. It usually appears on the leaves of vegetable crops, due to temperature changes. But other circumstances can also be the reason for its appearance - for example, an excessive nitrogen content or a lack of potassium. At a time when the plant becomes ill with powdery mildew, a white, powdery rash can be seen on the leaf plates. The plants themselves begin to grow more slowly, and soon dry out altogether.

Sometimes you can find on cucumbers, the so-called powdery mildew or peronosporiosis. A similar phenomenon is formed due to excessive moisture or after the plants have been watered with cold water. Too noticeable temperature changes can also provoke this trouble. It is quite easy to spot downy mildew on cucumbers. First of all, brown spots form on the leaves of the culture, which dry out after a few days. On the back of cucumber leaves, fungal spores can be seen, which are then scattered by wind and insects to neighboring areas and gardens. A disease is formed due to the fact that the seeds or plant debris are infected with the mycelium of the fungus. Especially often you can notice such an unpleasant phenomenon during the fruiting period. Also, in dangerous fungal diseases, attention should be paid to white and root rot, olive spot.

In bacterial diseases, there are many signs by which it can be understood that the plant is infected. For example, if the plant withers sharply, a sticky white mixture appears on it, or spots form on the leaves, then you can be sure that the bacteria are causing great harm to the cucumber bushes. The viral infection itself can persist on the stem of cucumber bushes until next year. In that case. When symptoms of bacterial wilting are observed, all the dried stems just need to be burned. Then on this site it will not be possible to plant melons and gourds for five, or even better six years. Also, you cannot collect seeds from such plants, as they will also become carriers of diseases.

The bacterium Pseudomonas burgeri Pot is the worst causative agent of wet rot. Most often, the disease manifests itself due to the fact that the infected seeds did not undergo special treatment before planting. In most cases, the disease manifests itself and proceeds slowly, and its special activity is noticed only at very low air temperatures. Therefore, at first, summer residents or gardeners generally may not understand the real cause of damage to the plant, scolding a low-quality variety of cucumbers or freshness of seeds. The first signs of wet rot include factors such as slow development of shoots, the appearance of dry and withering leaves on the bushes, the terrifying shape of the grown cucumbers, spots of an oily structure on the leaves of the plant, soft stems and a brown mass inside the fruit. Such diseases begin to spread throughout the site at very high humidity levels, and plants planted in greenhouses and greenhouses are especially at risk of infecting them.

Due to the angular spotting, cucumbers can die in a very short period of time. In addition, this disease is considered the most dangerous. Since it spreads very quickly, being transmitted from one plant to another. The infection is scattered over the site precisely during the wind or rain with the help of water droplets. There are also other ways of spreading the disease - infected seeds or insect pests. You can understand that a plant is infected if brown spots are visible on its fruits or leaves. Harmful bacteria thrive best during wet and warm weather.
