Pesticide Registrations and Actions

 On January 24, the EPA published a rule that revokes all
tolerances for residues of the herbicide oxadiazon. Tolerances are being revoked
because the active ingredient is no longer registered for food uses. The
revocations are effective April 24, 2003. Registrations remain in effect for
turf and ornamentals. (EPA Pesticide Program Update, 1/27/03).
