The intent of this network is to inform interested parties of recent or impending pesticide use cancellations, tolerance revocations, and similar items of agricultural interest. To the best of our knowledge, the uses mentioned here, unless otherwise indicated, will not appear on any label registered by the USEPA after those uses are canceled. We recommend that you express any concerns or questions you have to the contact mentioned below or to your NAPIAP State Liaison Representative. If you wish to contact us at USDA, our phone number is 301-504-8846, our fax number is 301-504-8063, and our email address is ksmith@asrr.arsusda.gov.

CANCELLATION OF SEVERAL METHAMIDOPHOS (MONITOR) USES

Bayer Corporation and Valent USA, the sole U.S. registrants of the insecticide/miticide methamidophos, have requested that their registations for methamidophos be terminated except for use on COTTON, POTATOES, and TOMATOES. These amendments to the registrants labels will be effective on 12/29/97, unless the USEPA publishes a notice in the Federal Register modifying this proposed order. This action was taken because of estimated occupational risks to agricultural workers and acute worker exposure incidents associated with methamidophos use. The registrants are taking these measures to mitigate risks before the end of reregistation which is expected in 1999 for methamidophos. The agricultural sites affected are as follows:

REGISTERED USES SUPPORTED by Bayer and Valent which are expected to be reregistered: COTTON, POTATOES, and TOMATOES (SLN in AL,CA,DE,FL,GA,IN, LA,MD,MI,NC,NJ,OH,PR,SC,TN,TX,VA).

REGISTERED USES UNSUPPPORTED and expected to be DELETED: ALFALFA (SLN in AZ,CA), BERMUDAGRASS (SLN in AZ), BROCCOLI, BRUSSELS SPROUTS, CABBAGE, CAULIFLOWER, CELERY, CLOVER (SLN in CA), CUCUMBERS (SLN in FL,GA,LA), EGGPLANT (SLN in FL,GA), LETTUCE (SLN in AZ,CA,FL), MELONS (SLN in AZ,CA,FL,GA,LA,TX), PEPPERS (SLN in CA,FL,GA,LA,NM,TX), and SUGAR BEET.

*SLN = Special Local Need or 24(c) in the indicated state(s)

After 12/31/97, methamidophos registrants, distributors, and dealers may not sell or distribute existing stocks of products labeled with deleted uses. End users may use existing stocks until such stocks are exhausted. Comments, labeled with the docket number OPP-64033, should be sent by postal or email to the Public Information Branch of EPA by 8/1/97. METHAMIDOPHOS -- continued
