What is a Bacterial Pear Burn?
Bacterial burn - a dangerous disease that can finally destroy not only the harvest of pears, but also the trees themselves.

Symptoms
The problem has a pronounced symptomatology, which allows not to lose time, but to begin to save the affected trees.
Symptoms of the disease:
- blackening of the inflorescences is the starting symptom. The inflorescences become black in color, they dry out and remain on the tree in such a state, they do not fall off;
- buds darken, becoming black, dry up, but do not fall off;
- the leaves turn black, the branches are all parts of the tree.
As a result, the black shroud covers the entire tree, coming down from the top. The trunk of the tree itself blackens, it finally dries out. The result of disease activity is a lifeless, dead tree.

With insufficient content of copper sulfate, the mixture will lose its "lethal" force, with excessive - it will burn the leaves.
Treatment with the solution should be carried out five times a year:- the first time is the period of the appearance of the kidneys;
- the second time - at the time of their dissolution;
- the third - after flowering;
- the fourth - 14 days after the previous one;
- the fifth is after harvest.
Only in this way can you save the trees from the disease.
However, if there is no improvement, or the spread of the disease is noticed, then the bacterium is mutated and insensitive to this method.
Such cases are not uncommon. In case of inefficiency, it is necessary to resort to spraying with other fungicidal preparations;
Radical treatment not one tree, but the whole planting is the destruction of the affected pear.If it is obvious that the pear is hopelessly captured by the pest, it should be uprooted and burned right on the spot.
When moving to another place, the probability of spreading the disease to other pears is high.
Sometimes better to donate one plant to win the whole war on the disease.
