Profitability in global food markets requires meeting high food quality sanitary and phytosanitary standards, often through the judicious use of crop protection materials, including pesticides. At the same time, many export market targets for US fruit crops set standards for maximum pesticide residue limits (MRLs) that are often lower than the domestic tolerances held by the USEPA. Meeting this challenge is especially difficult with the recent prevalence of late season invasive pests, like the Brown Marmorated Stink Bug (Halyomorpha Halys) (Stal) (BMSB) and Spotted Wing Drosophila (Drosophila suzukii) (SWD). Fruit growers need more data to determine which compounds hold the highest risks of rejection for export-bound crops. These data will also support establishment of “Export PHIs” guides that growers can use to avoid load rejections from export-target countries. Treatment regimens with minimum and maximum seasonal applications, addition of adjuvants, and the use of post-harvest water rinsing were tested for their effects on residue levels at harvest.
