EPA is designating the use of the active ingredient, potassium triiodide as a non-food use pesticide when applied to melons, grapes and bananas grown in foreign countries, and is adding an entry to 40 CFR 180.2020 noting the non-food use determination. This determination is based on the Agency's evaluation of data which indicates that dietary exposure to iodide and/or iodine resulting from the application of potassium triiodide to melons, grapes, and bananas is expected, to the extent any is present, to be indistinguishable from the background levels of existing dietary exposure resulting from the naturally- occurring sources of iodine chemicals. The effect of this designation is that EPA does not require that a tolerance or exemption from tolerance under section 408 of the Federal Food, Drug, and Cosmetic Act, 21 U.S.C. 346a, be established as a condition of registration of the pesticide under the Federal Insecticide, Fungicide, and Rodenticide Act, 7 U.S.C. 136 et. seq.
