   mentioned  uses submitted by Canyon Group to be added to their halosulfuron label and  approved by US
   EPA are eligible for exclusive use provisions since they were obtained for minor crops.  Specifically this
   section states "With respect to data submitted after the enactment of this clause (Augusts, i996) !? s^
   applicant or registrant to support an amendment adding a new use to an existing registration, that d' ocs nut

   not, without the written  permission of the original data submitter be considered by the Administra.or to
   support an application for a minor use by another person during the period of 10 years following the dpte
   of submission of such data,"

  By this letter, Canyon Group is applying for exclusive use of the data we provided for pea and beans,
   succulent shelled,  subgroup 6B; pea and bean, dried shelled, subgroup 6C; vegetable, tuberous and corm,
  subgroup 1C; bushberry, subgroup 13-07B; rhubarb, apples and okra.  All are minor uses and all are on
  the EPA approved label. All data for these minor uses was provided to the Agency after enactment of the
