Ecological Incident Statement for Ecological Risk Assessment Problem
Formulation

Fenoxycarb (PC Code 125301)

The Agency has received one report of adverse field effects to
non-target animals that was linked to use of fenoxycarb.  In 2000,
mortality of approximately 100 catfish occurred in a pond in Texas
following application of fenoxycarb and abamectin adjacent to the pond. 
Although the incident was likely related to runoff of these pesticides
during a rain event, the Agency does not know if the mortality was
caused by exposure to fenoxycarb or abamectin, or a combination of the
two.  This is the only major incident reported to the Agency linking
fenoxycarb use to any adverse effects to nontarget animals or plants. 
Aggregate reports from the registrants, however, have identified six
minor incidents of adverse effects to plants and one minor incident of
adverse effects to a nontarget invertebrate.  The Agency has received no
incident report from pesticide registrants concerning fenoxycarb
contamination of ground or surface water.

A lack of reported incidents does not necessarily mean that such
incidents have not occurred.  In addition, incident reports for
non-target plants and animals typically provide information on mortality
events only.  Reports for other adverse effects, such as reduced growth
or impaired reproduction, are rarely received.
