Mango leaves endings are getting folded getting dried and new leaves arebfalling down... Leaves getting holes.. we can see a inset in the folded leaves

Hi Dhanalakshmi Kolluri. It seems to be like Mango Leaf Webber , Tobacco Caterpillar , Powdery Mildew of Mango and initial stage of Sooty Mold . Click on green links for checking symptoms and taking control measures from Plantix library. Also need to apply good amount of Farm Yard manure or Vermicompost or any compost once in 6 months along with recommended dosage of fertilizers or you can also use fertilizer calculater available here on home page of Plantix to get good growth. Try well and take care of your Mango plant please.
