Seems Tom Theobald may not have told the whole story eh? about his so called coverup....
2010 Reclassification of Clothianidin Field Study for Pollinators
Though the registrant satisfied the basic study requirements for
registration in 2003, we required an additional field study to address
uncertainties about potential long-term effects of clothianidin on
honeybees. In 2007, we reviewed this study and determined that it
satisfied EPA’s field study guidelines. However, the Agency’s assessment
of the usefulness of this study has changed since the initial 2007
review, which is not unusual in the scientific field.
As EPA’s understanding of honeybee biology has improved, staff
scientists have started to recognize the challenges associated with
field pollinator study designs. While elaborate field studies can be
designed, there may be confounding effects that limit the utility of a
study but may not entirely discredit it.
It is clear that field pollinator studies cannot be viewed in the same
context as laboratory studies where experimental conditions can be
strictly manipulated. Recognizing the complexity of conducting field
studies, EPA is endeavoring to make the best use of existing data to
address uncertainties. Although EPA noted deficiencies in the
clothianidin pollinator field study, including some cross contamination
between treated and non-treated (control) experimental plots and
inadequate separation between treated and control portions of the study,
there was useful information that could be used to qualitatively
describe hive survival following exposure to clothianidin.
The reevaluation of the study in question does not change the Agency’s
conclusion that the registered uses of clothianidin meet the FIFRA
risk/benefit standard for registration. Clothianidin generally poses
less risk to agricultural workers and fish and wildlife when compared to
the insecticide alternatives...
