Hello Kannan,
Sorry for delay response....
Coming to your question my farm is located in Bodhan (Nizamabad,Andhrapradesh). From last month and so we have noticed that new leaves are falling heavily and severe thing is that leaves which are present are turned to black and also noticed black spots and after that entire stem is dried and I have no clue what needs to done..
Age of the trees 10 years old.I have taken this info to local farmers depo and they have given Bavistin,Spedomicin and i have missed other two medicine and we have sprayed.
Can you please suggest is there any way of giving medicine directly to soil..
Thanks in Advance waiting for your Suggestion...!!!
