                    Walworth  County, South Dakota
                        The information in this pamphlet is similar to
                        what the U.S. Environmental Protection
                        Agency (EPA) expects to distribute once our
                    Endangered Species Protection Program is in
                    effect. The limitations on pesticide use are not
                    law at this time, but are being provided now for
                    your use in voluntarily protecting endangered and
                    threatened species from harm due to pesticide
                    use. We encourage you to use this information.
                    We also welcome your comments.

                     The Endangered Species Act is intended to
                    protect and promote recovery of animals and
                    plants that are in danger of becoming extinct due
                    to the activities of people. Under the Act, EPA
                    must ensure that use of pesticides it registers will
                    not result in harm to the species listed as
                    endangered or threatened by the U.S. fish and
                    Wildlife Service, or to habitat critical to those
                    species' survival. To accomplish this, the EPA
                    expects to implement program requirements
                    beginning in 1994. This program will protect
                    endangered and threatened species from harm due
                    to pesticide use.
                     EPA requests your comments regarding the
                    information presented in this publication. Please
                    let us know whether the information is clear and
                    correct. Also tell us to what extent following the
                    recommended measures would affect you typical
                    pesticide use or productivity. This information
                    will be considered by EPA during the final stages
                    of program development

           About This Publication
                     ;i
             This publication contains a County Map
           showing the Area within the county where
           pesticide use should be limited to protect listed
           species. These areas are identified on the map by
           a shaded pattern. Each shaded pattern
           corresponds to a species in need of protection.
             The Shading Key shows the name of the species
           that each shaded pattern represents and often
           describes the shaded area. The area may be
           described in terms of Township, Range, and
           Section or by giving details about the habitat of
           the species.
             The first column of the "Table of Pesticide
           Active Ingredients" lists the active ingredients for
           which there :shou.ld be limitations on use to
           protect certain species. The next columns are
           headed by the shaded pattern of the species with
           Codes listed underneath them.
             The Code indicates the specific limitation that
           is necessary to protect the species. The section
           titled Limitations on Pesticide Use explains the
           code.      i

           Does This Information Apply to You?

             To determine whether this information applies
           to your use of a pesticide, review the questions
           below. The information applies only if you
           answer "yes" to both questions:
              Do you intend to use pesticides within or
               near the shaded area on the county map?
              Are any of the ingredients listed on the front
               panel of your pesticide product label named
               in the "Table of Pesticide Active
               Ingredients"?
             If you answer "yes" to both questions, you
           should follow the instructions on "How to Use
           This Information" to determine if you should
           limit use of the pesticide to help protect listed
           species.
             If you answer "no" to either questipn, you
           should follow the usage directions on the
           pesticide product label.

How To Use This Information
1) On the county map, find the specific shading pattern(s)
    in or near the area where you intend to apply pesticides.

2) Read the descriptor under the Shading Key for the
   pattern(s) to  identify the specific area involved.
3) In the "Table of Pesticide Active Ingredients," locate the
   active ingredient in the pesticide you intend to apply.

4) Locate the code to the right of the active ingredient name
   and under the shading pattern(s) that apply to you.

5) When using the pesticide, find the code(s) described
   under "Limitations on Pesticide Use" and follow the
   limitation given.
6) If you are applying more than one listed active ingredient
   or applying a listed active ingredient in an area with
   more than one shading pattern  (species), multiple codes
   may apply. If so, you should follow the most restrictive
   limitation.
7) Read the information on Reducing Runoff and Drift in
   this pamphlet.

                                     Reducing Runoff and Drift
Careful use of pesticides can diminish harm to the environment and reduce exposure of endangered and threatened species
to pesticides. Using pesticide runoff and drift measures may be helpful in keeping more of the applied pesticide on the
field and may also lower your costs of pesticides.
Runoff
Where possible, use methods which reduce soil erosion, such as limited till and contour plowing; these methods also
reduce pesticide runoff.
Where feasible, use application techniques such as T banding and in-furrow techniques, which incorporate the pesticide
into the soil.
Pesticides with ground water warning labels are more likely to enter ground and surface water than those without such
warnings. When possible, use a pesticide that does not contain a ground water warning label.
Keep Informed about changing weather conditions, and try to avoid pesticide application when heavy rainfall is expected.
Drift
Wind direction, speed, and evaporation are important factors in reducing drift. Most importantly, pesticides should be
applied when the wind direction is away from areas of concern; try to avoid application during periods of high winds.
Avoiding applications during the hottest part of the day, when evaporation is highest, will further reduce drift.
When high winds and excessive evaporation are not present, a drift retardant may be useful for aerial applications.
Using the largest droplet size compatible with the pesticide coverage will reduce drift. Typically, higher spray volumes
will also result in less drift.
