The Purdue Improved Crop Storage (PICS) bag is a low-cost, simple, and effective technology for low-resource farmers to help them preserve their dry crops after harvest with minimal losses due to storage insects. PICS technology involves storing grain in triple layer plastic bags. These bags are a great option for farmers who see major losses in their crops each year due to insect pests. The bags eliminate insecticide use and enable farmers to store and sell their crops at peak times, instead of selling at harvest when price is at the lowest. PICS technology also ensures farmers have enough supply of clean grain for home consumption for many months after harvest.
