The intent of this network is to inform interested parties of impending pesticide use cancellations and to afford those parties the opportunity to affect decision made by the pesticide registrants in concert with EPA. To the best of our knowledge the uses mentioned below will not appear on any label registered by the EPA following their expected cancellation.

The following information has been obtained from EPA from a letter sent to registrants claiming a generic data exemption for Ethyl Parathion.

A/S Cheminova, the sole registrant who has committed to produce the generic data, has notified EPA that it had decided not to support residue data for certain crop uses (see List I) that are required by the December 1986 Ethyl Parathion Registration Standard.

EPA notified by registered mail dated 3/7/91 all registrants of ethyl parathion-containing products that they have until 30 days from receipt of the letter to indicate their intention to provide the required data to support one or more the uses to be dropped. Otherwise all unsupported uses must be removed from their labels within 90 days of receipt of the letter.

Commodity organizations may have to provide financial and/or material support to conduct the required studies. Crop residue data are generally the easiest and least expensive to deal with. However, if additional metabolism data will be required or if concerns exist over the Acceptable Daily Intake (ADI), the cost and complexity of supporting these uses can increase substantially.

If any of these uses are important to you, you must act quickly. Contact Mr. Kurt Halling (201-338-3377) NOW WITHOUT DELAY. Additionally, contact Joanne Edwards (703-308-8059) Reregistration Branch, Office of Pesticide Programs at EPA. She has a list of registrants.
