Esme konsi bimari se yah sukh raha hai

Dear Arjun Singh how are you welcome to plantix community dear as per your image I will suggest you that your plant is infected by shoot canker dear

The main issue is shoot canker dear so remove the dry stem and shoot and apply coppor oxychloride dear it will control the disease from further infection and so your mango tree will start growth here is attached picture dear kindly look it
