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.

Hope this helps and happy gardening.
