There is also such a disease as milky shine, this disease belongs to the category of the most dangerous fungal. The fungus will gradually infect one branch after another, and the leaves will acquire a silvery-lead color. Over time, the branches begin to die off, and eventually the entire tree dies.

The causative agent of this disease can be activated with mechanical damage to the cortex. That is why such small wounds should be regularly washed: this must be done with four percent iron sulfate or three percent copper sulfate. Diseased branches should be cut out immediately. Places of cuts should be covered with garden varnish or oil paint on drying oil. Those gardening tools with which to work should be urgently disinfected with alcohol. In the event that a tree is very strongly affected by such a disease, it should be uprooted.

There is a disease called gum flow or the formation of hollows. The bacteria will multiply in the jelly-like organic matter. In the event that plum trees grow in damp and cold places, then this disease occurs most often.

As for preventive measures, it is necessary to clean out all wounds with a knife, and then cover them up with a garden varnish. Such measures will prevent the development of this disease. In the case when the wounds are of a larger size, then they have to be tied with a bandage.

Smallpox or sharka plums belongs to the category of viral diseases. The disease will manifest itself when exactly a month has passed after flowering. It is very easy to visually notice such a disease: spots appear on the leaves in the form of light rings, sometimes such spots are similar to wide blurry stripes. As for the fruit, dark purple stripes appear on them. The very same pulp will be colored in red-brown tones up to the very bone. Such fruits are absolutely impossible to eat, and by their appearance they are extremely ugly. Already twenty days later, such fruits seem to fully ripen and then fall off. The carriers of this virus are herbaceous plants: white lamb, black nightshade, white clover and white sweet clover. However, the main carrier of such a disease remains nothing more than aphids.

Timely prevention of the appearance of such a disease will allow the removal of root shoots. Also, weeding of weeds should also be attributed to preventive measures, which must be performed with enviable regularity. After all, it is on weeds in the summer that aphids will settle. Affected branches should be pruned. In the event that the tree is already very badly affected, it remains only to uproot it, because there are no methods of chemical protection against such a disease.

Chlorotic ring spot is another viral disease. This disease is very easily distinguishable by visual signs. Light green or yellowish rings and stripes appear on the leaves. Due to such a disease, you can lose about half of the entire crop. Transmission of the virus occurs with pollen, but sometimes seed transmission can also occur.

With regard to preventive measures and methods of treatment, it should be noted that careful attention must be paid to the selection of exceptionally healthy planting material. As soon as the first signs of this dangerous disease become noticeable, branches and leaves should be cut off immediately. In the event that the defeat is already massive, then there is nothing left but to remove this tree from the summer cottage. Therefore, the solution will be to observe the plum trees and detect the slightest problems in a timely manner.
