Storing Blackgram

Dear Forum Members

We are in the midst of harvesting Blackgram (VBN4) variety. We would like to retain the blackgram for a long period of time with the skin. I understand that blackgram cannot be stored with skin as insects will damage blackgram.

Is there an organic treatment available where I can store large quantities of blackgram with skin. Suggestions will be appreciated.

Thanks.
