In case you missed it – and I did – the Federal Insecticide, Fungicide, and Rodenticide Act Scientific Advisory Panel (FIFRA SAP) will convene a three-day meeting (October 30-November 1, 2013). The details are hidden here

FIFRA SAP is an extremely influential and powerful panel.  It   serves as the primary scientific peer review mechanism of EPA’s Office of Chemical Safety and Pollution Prevention (OCSPP) and is structured to provide scientific advice, information and recommendations to the EPA Administrator on pesticides and pesticide-related issues as to the impact of regulatory actions on health and the environment.

The meeting will review scientific uncertainties associated with corn rootworm (CRW) resistance monitoring for Bt corn Plant Incorporated Protectants (PIPs).

In plain English, Bt or Bacillus thuringiensis is a gram positive, soil-dwelling bacterium, commonly used as a biological pesticide; alternatively, the Cry toxin may be extracted and used as a pesticide.

The EPA seeks to improve the resistance monitoring program for CRW by addressing the scientific uncertainties associated with this insecticide. Specifically, EPA's charge to the panel will include the following topics: population sampling (random vs. focused), triggers (i.e., field damage to Bt corn) for investigations of potentially resistant populations, bioassay techniques, defining resistance (in the context of bioassay results), and remedial action plans in the event of resistance to contain or limit the spread of resistant populations.

More details here.

The outcome of this meeting will directly impact manufacturers involved in corn seed ($7 billion) and/or corn insecticide ($45 billion global market) development.

Major players in the Bt pesticide market include Monsanto,  Syngenta, Bayer Crop ScienceBASF, Dow AgroSci, and Dupont.
