4 ORAL NOTIFICATION AND POSTING RESTRICTED ENTRY INTERVAL (REI) PESTICIDE TOLERANCE LEVELS For more information about the WPS and the training requirements for uncertified workers and handlers, download the revised 2005 edition of EPA’s How To Comply manual (www.epa.gov/agriculture/twor.html). The WPS requires employers to give notice of pesticide applications to all workers who will be in a treated area or walk within 1⁄4 mile of a treated area during the pesticide application or during the restricted entry interval (described below). Notification may either be oral warnings or posting of warning signs at entrances to treated sites; both are necessary if the label requires dual (oral and posting) notification. A current list of dual-notice pesticides registered for use in Wisconsin may be downloaded from ipcm.wisc.edu/pat. Wisconsin’s ATCP 29 posting rule is designed to protect the general public as well as workers. Thus, it requires posting of areas treated with pesticides having a dual notification statement or, for nonagricultural pesticide applications, if the label prescribes a restricted entry interval for that particular application. Refer to On-Farm Posting of Pesticide- Treated Sites in Wisconsin for a flow chart guiding users through a series of questions to determine when posting of treated sites is needed, what warning sign to use, and where the sign should be located. It also covers the separate posting requirements for chemigation treatments. This publication is available from your county Extension office or it may be downloaded from the Pesticide Applicator Training web site (ipcm.wisc.edu/pat). There are separate posting requirements for applications involving chemigation. A restricted entry interval (REI) is the length of time that must expire after pesticide application before people can safely enter the treated site without using personal protective equipment. Pesticide residues on a treated crop or in a treated area may pose a significant hazard to workers or others who enter the area after treatment. Therefore, nearly all pesticides affected by the WPS (see above) have an REI. Check the Agricultural Use Requirements section on the label for the specific restricted entry interval for your product. These intervals must be strictly observed. In Public Law 518, the Food and Drug Administration (FDA), a division of the U.S. Department of Health and Human Services, warns “Food shipments bearing residues of pesticide chemicals in excess of established tolerances will be contraband and subject to seizures as adulterated.” This applies to both raw and processed foods. The amount of pesticide residue in or on a food material at harvest must fall into established tolerances, expressed in parts per million (ppm). The actual amount of pesticide chemical found in a food at harvest depends in part on the amount applied to the crop and the length of time since the last application. Therefore, growers are responsible for strictly following label information with regard to maximum spray dosage and the interval between the final pesticide application and harvest. The FDA advises pesticide users to follow directions on recently registered labels, so they don’t exceed the residue tolerances for the specific materials. Use table 3 as a guide to the interval between the last pesticide application and harvest. The preharvest intervals refer to pesticide use on cranberries only; other crops may have different intervals. The pesticide label also lists this information.
