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.
