On January 28, 2015, the U.S. Environmental Protection Agency (EPA) announced that it has made available for public comment its proposal to improve the corn rootworm insect resistance management program currently in place for registrations of plant-incorporated protectants (PIP) derived from Bacillus thuringiensis (Bt) in corn. The EPA framework contains a number of controversial provisions, including the following proposed restriction of soil applied insecticides (SAI): “SAIs must be prohibited from use in combination with Bt corn for controlling corn rootworm. This can be done via bag tag language, grower guides, and terms of registration.” Concerns with the process by which this and other provisions can or should be developed and published for public comment are among the issues of concern. Comments are due March 16, 2015.
