The most common diseases of cucumbers

The main, most widespread and at the same time fraught with the greatest danger of cucumber diseases are anthracnose, green speckled, also known as English mosaic, root rot, powdery mildew, and also ordinary cucumber mosaic.

Such diseases of cucumbers as English mosaic and ordinary mosaic have much in common, in particular, they make themselves felt with approximately the same symptoms. However, the latter affects a huge number of a wide variety of plants (according to scientists, their number exceeds seven hundred) and is provoked by virions belonging to the group of cucumoids, while the first type of disease is prone to affecting a small number of plant species, and its occurrence is caused by the effects of viruses belonging to the group of tobamoviruses.

Another very dangerous ailment for this culture is anthracnose, which can affect any cucumber, but is most often localized in film greenhouses. Powdery mildew appears, as a rule, on the true leaves of the plant, but it can also be localized on the cotyledons, forming a characteristic whitish-gray bloom. Downy mildew is characterized by the fact that the plants affected by it die very quickly, while this disease is difficult to identify in time due to the absence of obvious signs of damage. As for a disease such as root rot, it manifests itself in the form of characteristic browning of the roots, as well as the root necks of plants, as well as yellowing and sticking of affected leaves located on the lower tiers of the stem.
