     The  data  presented  within   this   Profile  have  been
gathered from  a  wide range of sources.  Within  the  limits of
these sources, the data presented are complete and accurate.

     Data  shown  in  the  tables  entitled  "Registered Labels"
and  "Site/Pest Confirmation" and  portions of  the  introduc-
tory  information,  have been extracted  and compiled from the
Environmental Protection Agency's Pesticide  Data Base.   This
system  is  maintained  by  the  Office  of  Pesticide Programs
(OPP).

     The data  used  to  compile the recommendations section of
the  Profile  were  solicited from  and  submitted  by  the indi-
vidual  sources   or   gathered   by  standard  library   search
methods.

     We thank all who have  participated  in  this program for
their  cooperation toward  making  this  effort   a  successful
one.
