Summary of Meeting:

This meeting was held at the request of Angus Kelly of the National
Cotton Council (NCC) to discuss the need for early season use of
dicrotophos.  This meeting is subsequent to a prior meeting of October
2005, in which Amvac and the NCC requested an additional application of
dicrotophos for critical late season use for plant and stink bugs.  The
EPA granted the additional late season application, yet restricted the
early season use since the cotton entomologists agreed at that time that
the late season application was more important.  During this meeting
with NCC and stakeholders, Dr. Catchot stated that alternatives for
thrip control caused flare ups in spider mite and aphid populations,
thus the need for use of dicrotophos early season.  The cotton
entomologists in attendance stated that since 2004 they have seen
increased resistance to alternative neonecitinoids used to treat cotton
aphids, and increased number of pesticide applications for spider mites
which were previously not a concern with dicrotophos applications. 

EPA has yet to receive a label reflecting the required mitigation
measures from October 2005.  As a result, the Agency told Amvac and the
other attendees that Amvac must submit a label with the required
mitigation.  The Agency will also consider any data submission that the
cotton entomologists submit, and the draft label can be revised if the
data warrant additional use.
