EPA Approves Bollgard II “Natural Refuge”
8 June 2007 Some in the research community, however, take the stand that yield loss from structured refuges has been exaggerated, stating that the 5% embedded refuge hasn’t greatly affected yields, as worms move out of the refuge but moths don’t come in from the non-refuge cotton. Entomologists are concerned that a natural refuge is not the best way to manage insect resistance, and apprehensive that there may not be enough of a natural refuge across all affected regions.
The natural refuge option will affect producers of Bollgard II cotton in the states of Alabama, Arkansas, Florida, Georgia, Kansas, Kentucky, Louisiana, Maryland, Missouri, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, most counties in Texas, and Virginia, all areas where tobacco budworm and cotton bollworm are primary pests.
