Since Bollgard® cotton was introduced to U.S. cotton growers in 1996, the U.S. Environmental Protection Agency has required growers to plant and maintain non-Bollgard cotton refuges to help prevent or delay insect resistance. Monsanto has voluntarily monitored Bollgard cotton growers for refuge compliance through a series of grower on farm visits. Monsanto, with the assistance of multiple institutions, individuals and agencies, has attempted to inform all growers of refuge requirements. Surveys of Bollgard cotton growers across the Cotton Belt from 1996 through 2001 show that a vast majority of growers appear to be following refuge guidelines.
