Many diseases and pests of apricot can lead to a decrease in the yield of this crop. This plant is unpretentious, but with a lack of nutrients, as well as growing in unfavorable climatic conditions, its natural resistance decreases. This makes the apricot more susceptible to pests and infectious diseases.

Common apricot diseases
Apricot is susceptible to the negative effects of a number of fungi, viruses and bacteria. Common infectious diseases of this culture include:
- cytosporosis of stone fruits;
- bacterial necrosis;
- brown spotting;
- clasterosporium disease;
- monilial burn of apricot.
The appearance of a large number of small tubercles on the bark of the tree indicates damage to the tree by cytosporosis of stone fruits. These formations have a gray-brown color and are clearly visible upon close examination. This is a disease caused by a fungus, and it leads to a disruption in the flow of juices in the bark, which causes the leaves to wilt and the infected branch die. All affected branches should be removed and burned. To treat the early stage of the disease, it is required to spray its branches with an antifungal agent containing copper.
Bacterial necrosis affects all tree structures. First, in the spring, formations are formed on the bark, similar to sunburn. In the future, ulcers appear in their place, from which gum begins to leak. The bark takes on a brown tint. When signs of this disease are detected, all affected branches are cut off down to healthy tissue and burned. Slices must be disinfected with copper sulfate. After that, they must be treated with garden varnish.
When apricot trees are affected by brown spots, gray-brown spots with a dark border are formed on them. In the future, holes are formed on the affected leaves. Damaged greens die off prematurely. To prevent damage to the tree by this infection, it is required to disinfect them with antifungal agents during the formation of kidneys.
Clasterosporium disease is characterized by the appearance of small red-brown spots on fruits and leaves. The fruits are further deformed, and holes form on the leaves. A severe lesion is characterized by the appearance of a large number of reddish-purple spots on the branches. Subsequently, ulcers form at the sites of these defects, from which gum begins to flow.
All damaged branches must be cut and burned. In addition, damaged leaves must be collected and disposed of in the fall. To prevent the spread of infection, branches must be treated with 3% Bordeaux liquid. During the period of bud formation, it is necessary to perform treatment with Mikosan or Horus.
Minilial burn often affects trees during the flowering period. The pathogen can be carried by pollinators. Cold and humid weather promotes the spread of infection. To prevent the spread of infection and infection, the kidneys must be treated with preparations containing copper. In addition, it is recommended to spray the crown with Topsin-M, Tomaz or Strobi.
Gum flow does not always indicate tree infection. A similar phenomenon can be observed if the apricot grows in unfavorable climatic conditions for it. It is necessary to clean out the damaged areas and up to living tissue. Then these areas need to be treated with copper sulfate. After that, it is necessary to carefully cover up with garden var.
Apricot pests
Apricots suffer most from aphids. These insects are often found on the trunk and back of the leaves. They feed on the sap of the tree, weakening it. To eliminate them, it is not enough to carry out an insecticide treatment. Efforts should also be directed towards fighting ants.
In addition, apricots often suffer from the moth. Butterflies lay eggs on a tree. The hatched caterpillars eat the fruits, and then go into the ground for wintering. To prevent their spread, trees should be treated with insecticides in spring and autumn.
