        History
     All pesticides sold or distributed in the United States must be
registered by EPA, based on scientific studies showing that they can be used
without posing unreasonable risks to people or the environment. Because of
advances in scientific knowledge, the law requires that pesticides which were
first registered before November 1,  1984, be reregistered to ensure that they
meet today's more stringent standards.
     In evaluating pesticides for reregistration, EPA obtains and reviews a
complete set of studies from pesticide producers, describing the human
health and environmental effects of each pesticide. The Agency develops
any mitigation measures or regulatory controls needed to effectively reduce
each pesticide's risks. EPA then reregisters pesticides that can be used
without posing unreasonable risks to human health or the environment.
     When a pesticide is eligible for reregistration, EPA explains the basis
for its decision in a Reregistration Eligibility Decision (RED) document.
This feet sheet summarizes the information in the RED document for
reregistration case 4118, virelure.

     Viirelure is an insect pheromone that attracts male artichoke  plume
moths. They are either attracted to a trap, where they become entrapped and
die, or the release of the pheromone from a dispenser disrupts then: mating
activity. The mode of action is non-toxic.
     A manufacturing-use product and two end-use products are presently
registered for virelure. End-use products are twist-ties that are  distributed
throughout the affected area.
     Because of its containment, virelure's use sites are considered
terrestrial non-food. The artichoke plume moth is only a pest of artichokes;
therefore, virelure would be used in areas where artichokes are  grown.

     Virelure was first registered as a pesticide hi the U.S. in 1981.  In
1989, there were three registered end-use products and two registered
manufacturing-use products.  As of 1996, one manufecturing-use product
and two end-use products were registered; all other products were canceled
for non-payment of maintenance fees. Data on product chemistry were
received in response to a Data Call-in in 1993.

      Human Health
        Assessment
 Toxicity
      Adequate mammalian toxicology data on virelure are available for its
 use in a solid-matrix dispenser and will support a Reregistration Eligibility
 Decision (RED). Oral and inhalation toxicology indicate that virelure is
 practically nontoxic by these routes. Studies submitted for eye and dermal
 irritation resulted in a classification of Toxicology Category HI.

 Dietary Exposure
      Since there are no food uses of virelure, dietary exposure is not
 expected.

 Human Risk Assessment
      Based on the use pattern, the potential for dermal and eye exposures to
 pesticide handlers exists but is expected to be negligible. Residential
 exposure is not expected based on the use pattern.
     Environmental
       Assessment
      Adequate data are available to satisfy adverse risk concerns to
nontarget organisms. Virelure is practically nontoxic to terrestrial animals
Virelure is highly toxic to freshwater invertebrates and creates an oily
surface film on water that may adversely affect organisms that utilize the
water surface.  Based on its uses, studies for non-target plants are not
required.
      Based on the use pattern, the potential for exposure to non-target
organisms is not expected.
   Additional Data        The generic database supporting the reregistration of virelure for the
           Required   above eligible uses has been reviewed and determined to be substantially
                         complete.  Therefore, there are no further generic data requirements being
                         imposed at this time.

  Product Labeling        The labels of all registered pesticide products containing virelure must
Changes Required   comP!y with EPA'S current pesticide product labeling requirements. In
                         addition:
                        NPDES Statement - Manufacturing-use product labels must contain the
                        following NPDES statement:  "Do not discharge effluent containing this
                        active ingredient into lakes, streams, ponds, estuaries, oceans, or public
                        waters unless this product is specifically identified and addressed in an
                        NPDES permit.  Do not discharge effluent containing this product to sewer
                        systems without previously notifying the sewage treatment plant authority.

 Conclusion
   For More
Information
 Precautionary Statement - The following statement should appear under the
 "Precautionary Statement" heading on the label: "Causes slight eye and
 dermal irritation.  Avoid contact with eyes, skin, or clothing.  Wash
 thorougWy with soap and water after handling."

 Environmental Hazard - The following statement should appear under the
 "Environmental Hazards" heading on the label: "This product is highly toxic
 to aquatic invertebrates. Do not apply directly to water or to areas where
 surface water is present or to intertidal areas below the mean high water
 mark. Do not contaminate water by cleaning of equipment or disposal of
 equipment washwaters."

 Non-Food Use - In conformity with virelure's non-food use, labels should
 contain the statement: "Do not contaminate water, food or feed by storage or
 disposal."

      Based on the review of the generic data for the active ingredients
 virelure, the Agency has sufficient information on the health effects  of
 virelure and on its potential for causing adverse effects in fish and wildlife
 and the environment. The Agency has determined  that virelure products,
 labeled and used as specified in  the Reregistration Eligibility Decision, will
 not pose unreasonable risks or adverse effects to humans or the
 environment. Therefore, the Agency concludes  that, for products containing
 virelure fin twist-tie dispensers, all uses are eligible for reregistration.
