My mother used to grow a variety of beans called "sulpher beans". She may have grown them especially for making "shuck beans", I don't know..After the beans were dry she stored them in flour sacks for the winter...but I don't remember her putting anything on them before storing them..Some sulpher might have kept bugs out, but when tied tightly in a flour sack no bugs could get to them anyway.. Also, some one asked what "shucks" are, the ones used in a bed tick, well, that type of shuck came from the plant growth surrounding ears of corn..Removing the ear of corn was called "shucking corn". Farmers had a special tool, worn on the hand, for shucking corn.. G. Lee Hearl Abingdon, Va.
