The Purdue Improved Storage (PICS) bag, is an airtight storage bag that provides a solution for smallholder farmers to extend the storage time for their seeds and crops.
The PICS bag is a hermetic, or airtight, storage solution for smallholder farmers who suffer severe losses due to insects. The bags provide an effective method of controlling insects on maize for smallholder farmers and preserves the quality of the grain being stored.
According to the PICS website: “The use of PICS bags provides farmers the flexibility to sell their grains when they choose while supplying healthy, clean and insecticide-free food to their families throughout the year.”
