Interpretive Summary:

Technical Abstract: Nitric oxide (NO) fumigation is effective against all of 14 pest species tested to date. When conducted properly, NO fumigation is also safe to postharvest quality of fresh fruit and vegetables. In addition, NO fumigation resulted in better postharvest quality of fruit such as strawberries and apples. NO fumigation does not significantly increase nitrate or nitrite levels as residues in fresh and stored products. More recently, we demonstrated that nitrogen dioxide (NO2) can inactivate Aspergillus flavus spores and effectively control both bacteria and fungi on unpasteurized almonds. NO fumigations can be regulated to have desired levels of NO and NO2. Therefore, NO fumigation with NO and NO2 has potential to control pests and pathogens.
