Bean storage
First, before storage, dry seeds well in sun on tarpauline, sort and pour them inside the clean dry jerrycan, shake it and cover with soft plastic bag ad seal the jerrycan lid tightly and label with date sealed and the purpose. Once sealed, leave it for atleast a month and never open until time for planting to prevent new supply of air for eggs to hatch.
Finally, dont store beans for planting more than 6 month in a jerrycan as the seed viability may reduce.
