Erroneously IGST paid and utilized in GSTR.3B instead of CGST and SGST. How to resolve this?

I have a new form of client i.e. mandi trader.
My client has not done any business after gst implementation.
I have a few querries related to his work.
1. He makes purchases from local farmers so how he will show purchase in gst.
2. Whether reverse charge is applicable on purchases made by him.
3. What is gst rate on various grains and if rate is zero at what rate reverse charge will be applicable.
4. And if he makes sale in gst whether he has to file eway bill.
5. If any other special point that I need to keep in my mind please suggest.
Thanks in advance.
