Hi Chiara,
Thank you for contacting Yates.
Looks like the tree might be suffering from rot, which is common for matured citrus tree. You may look into
'Yates Anti Rot'. It is a systemic fungicide which is absorbed by the foliage and travels down to the roots, can be used on various plants to control phytophthora root rot, crown rot and collar rot.
