Brown spot of pear is, in fact, one of the most dangerous adversities of the European pear tree: it affects all the green organs of the plant, causing damage especially to the fruit , which goes into rot.

In areas prone to the spread of the disease, the following are carried out plant-protection treatments from the time of pear blossom until harvest to try to contain economic damage as much as possible. Brown spot of pear infections start from the leaves of the pear tree after the flowering period (which occurs between May and June) and increase in climatic conditions favorable to alternaria; in the worst case, they even affect more than 90% of the production.
