Bacterial diseases of roses and the fight against them
The most common diseases that can be triggered by bacteria are bacterial cancer of the roots and stems of the plant.
When the roots are affected, small growths begin to form on them, which subsequently increase. These peculiar "sores" are not only on the roots of the bushes, but also in the bases of the stems. If the disease is noticed at an early stage, then you can try to save the roses. To do this, you will need to carefully cut the growths from both the roots and stems. Severely affected areas of the root system should be removed completely.
After carrying out these measures, you need to treat the roots with a solution of copper sulfate, for about 5 minutes. Next, the root system must be thoroughly washed in clean water.
With this disease, all affected and removed areas of the plant should be burned. If you notice that treatment with vitriol has not brought visible results and the bush continues to be covered with growths, it should be dug up and burned to prevent the disease of other flower crops.
Of course, it is a pity to burn such beauty, but it will die anyway: solid growths will eventually begin to rot and completely destroy the plant.
Bacterial stalk cancer
The leaves of the affected roses begin to dry out, fade, curl, but they do not fall. This disease is also called a bacterial burn. The bark of the plant gradually begins to brown, and then dies.
This disease can be transmitted both by insects and infected garden tools. In order to save flowers, all damaged leaves and shoots should be cut. Next, you need to process the bush using a solution of zinc sulfate. Such procedures are carried out from 2 to 4 years to completely heal the plants.
