Suresh Gollar first of all thank you sir, you guide me very well, Sir I gave treatment to plants throughout drip and also on trunk of plant , the plants which were affected , will cure or not please guide sir...!🙏

Hi Ankur . Great - if it's in initial stage, definitely it will be controlled. You can cake control measures 2 to 3 times depending upon the intensity of infestation by changing chemicals every round as mentioned in above green link. Severely effected plants - just pick them and Burn and drench with above chemical at effected soil. Try your level best please.

Hi Ankur . It's ok.
