What are the most common diseases of plum trees?

Plums are susceptible to relatively several pests and diseases and require regular maintenance. To support strong and energetic growth, it is necessary to fertilize fruit trees and their spraying fungicides and pesticides. Some of the most common diseases of the plum trees that are caused by fungal infections are black knot, brown rot, mold with powder, verticillium defect, permanent pockets and plum pockets. Bacterial diseases affecting plums are crown bile, bacterial stain and shot. Plum diseases such as the virus of plum smallpox and plum are caused by pests such as aphids. A permanent canker is a similar fungal infection caused by vals cincta and v. Monsa leucostoma and causes oval Cankers to appear on the branches and trunk. In both cases, nodes and Cankers eventually repeat and kill it.

brown mushroom brown rot grows in the form of brown cHomacks on plum flows, sheeps and small branches and cause the flowers to dry and rot. A lot of destruction of fruit is also destroyed by the fungus taphrina , which creates hollow, enlarged spaces known as plum pockets in plum fruits. The fungus podosphaera oxyacanthae causes mold with powder, white powder growth on the underside of plum leaves that destroy the leaves and obscures the growth of the tree. Verticillium Wilt, which is caused by fungus verticillium alboatrum , also obscures the growth of plants by causing leaves that leaves with defects, wood turns and roots rot.

Crown gallbladder infection, which is caused by bacteria agrobacterium tumefacienes , produces cork tumors in plant tissue. Two more diseases of bacterial plums, bacterial stain and clearance are caused by xanthomonas pruni and pseudomonas syringae bacteria. Plum leaves appear stains and holes and the leaves then immortalize and fall out. BacteriaThe infection also produces holes to develop fruit, causing rot. The aphids spread the virus of plump smallpox and plum rust. In the first case, fruit production is affected by developing plums deforming or rotting, and in the second case, the plum is silver, turns up and cheer.

fungal infections are transmitted by wind or soil, while bacterial and viral infections can be transmitted by soil or carried pests. To alleviate plum trees, it will help to avoid planting a plum tree in a previously affected area. When taking care of a plum tree, which is already infected, it will be necessary to prune and burn the sick parts and spray the tree of fungicides, bactericides and pesticides. It is important to realize that fungicides function mainly as a preventive and may not have power on severely infected trees.
