Cherry plum diseases and the fight against them

The fragrant and juicy cherry plum is loved by many. It is low in calories, very tasty and incredibly healthy. Cherry plum can be eaten fresh or prepared from it in various dishes - for example, seasonings with its addition help the human body to better absorb fat and meat. But when growing these beautiful fruits, many summer residents are faced with a number of troubles. What kind of troubles can lie in wait for a bright cherry plum?

Cherry plum clotterosporia

This harmful attack, also called perforated leaf spot, affects the cherry plum at the very beginning of spring. Numerous reddish spots begin to appear on the leaves, framed by dark edges and turning into clearly visible holes after a week or two. Similar specks can appear on fruits. In the case of severe infection, the disease contributes to a noticeable reduction in the volume of the crop - the drying out leaves and flowers begin to fall off, the fruits dry out to the very bones, and the blackening buds stop developing.

On young branches of cherry plum, unpleasant purple specks quickly turn into sores. The bark slowly begins to crack, and gum oozes abundantly from it. Fruit trees gradually lose strength and stop growing.

To prevent the development of clasterosporium disease, it is important to try to prevent thickening of tree crowns - for this purpose, timely pruning is carried out.

Gray rot

The second name of this ailment is moniliosis. The surfaces of infected fruits are gradually covered with gray formations that are well visible to the eye, densely covered with mushroom spores. If the cherry plum fruits are located too close to each other, moniliosis easily passes from one berry to another.

Cherry plum coccomycosis

Around mid-June, tiny reddish-brownish specks can be seen on the tops of the leaves. A little later, these spots begin to merge. And on the inner sides of the leaves, the development of a characteristic pinkish powdery bloom begins. The yellowed leaves fall off prematurely, and the infected fruits dry out without having time to develop.

Milky shine on cherry plum

On cherry plum, a milky shine is quite often found. When this plague caused by fungal spores is affected, individual cherry plum branches begin to silver. As it develops, the disease penetrates deep enough into the wood, thereby provoking the development of stem rot. By about mid-July, the leaves begin to become covered with brownish specks and dry out. And after a while, the milky shine covers the trees entirely.

In order to prevent this unpleasant disease, the trees are recommended to be sprayed with various copper-containing preparations, and the cuts and wounds are treated with oil paint or garden varnish. As for whitewashing trees, in addition to boles, it is advisable to whitewash skeletal twigs.

False milky shine

The crowns of infected fruit trees begin to silver strongly (when damaged by an ordinary milky sheen, only their parts are silver), staining in grayish tones with a pronounced metallic sheen, and leaves prematurely crumble from the trees. The main reason for the development of this ailment is considered to be freezing of wood during the establishment of especially harsh winters.

Brown leaf spot

On the leaves of cherry plum, tiny yellowish-brownish specks appear, contributing to their further drying and rapid subsidence.

To cope with this scourge, during the period of staining of the developing buds, the trees are treated with one percent Bordeaux liquid. And then the treatment is repeated immediately after flowering and after another couple of weeks.
