Small scale fumigation treatments using different phosphine concentrations and durations at a low temperature will be conducted to determine effective treatment to control each insect species. Selected fumigation treatments will be tested on commercial iceberg and romaine lettuce determine effects on postharvest quality of lettuce. Large pallet-scale fumigation treatment will be conducted to verify efficacy and safety of selected low temperature phosphine fumigation. Additional research will be conducted to determine suitability of using a phosphine generator for fumigation at low temperature and to find an economical way to conduct low temperature phosphine fumigation to control western flower thrips on lettuce.
