A Comparison of Maximum Residue Levels (MRLs) for Pesticides Used on Apples to Export Markets December 20, 2011 CURRENT SITUATION:   Pacific Northwest apple exporters are concerned with meeting international pesticide regulatory standards for crop protection chemicals.  The list of chemicals and country-specific MRLs continues to change.  The table below summarizes the current understanding of the Northwest Horticultural Council (NHC) concerning MRLs for certain insecticides and fungicides in the top markets for Pacific Northwest apples.   For Taiwan, relevant government authorities have provided USDA officials with lists of chemicals targeted in official pesticide residue surveillance programs.  NHC staff has reviewed those lists to see which chemicals are likely to be used by apple growers in the Pacific Northwest.  Chemicals on the list below which are subject to official testing programs are marked with the ← symbol.  The NHC does not have this information for any other markets in the table.  These official testing lists are subject to change without notice and non-governmental groups wishing to make an issue of pesticide residues may conduct testing at retail on a much broader list of crop protection chemicals. This is only intended to be an initial guide to the export trade in certain deciduous tree fruits.  Tariff and non-tariff measures can change with great speed and frequency.  Commercially important information, such as MRLs, should be rechecked and verified with knowledgeable parties in the country of interest prior to sales or shipment.   The NHC assumes no responsibility for any errors or omissions incurred in preparing and publishing this industry bulletin. Any errors or omissions noted, or questions or advice related to the bulletin, should be directed to the persons listed below as contacts.  CONTACT:  For additional information contact Debbie Carter or Dr. Mike Willett, Northwest Horticultural Council at 509/453-3193.
