1996-1997 New England Apple Pest Management Guide


 RESTRICTED ENTRY INTERVAL


All agricultural pesticides labeled after April 1994 have a Restricted Entry Interval (REI) stated on the label. Pesticides with older labels that do not have an REI can be used according to the label directions. However, some of these older labels specify reentry intervals, and the protective equipment that must be worn for reentry during the specified amount of time after the pesticide was applied. Pesticides labeled before the advent of worker protection standards will be available until the supply is depleted. The REI values listed below (see Table 10) are the best information available as of February 1996. Manufacturers may write the label with a longer REI than required by the EPA, or the EPA may change its minimum REI requirement. To know the use restrictions for a pesticide you must READ THE LABEL!

PESTICIDE RESIDUE TOLERANCES

Federal laws warn that 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 as 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 do not exceed the residue tolerance for any material. Use the following table as a general guide, but verify the preharvest interval by checking the label before using the product. This chart refers to apples only; other crops may have other preharvest intervals.
