Fall armyworms in southern Florida survived a pesticide engineered into corn by Dow Chemical Co. and DuPont Co., the second insect to show signs of resistance to genetically modified crops in the U.S., according to a study.
Fall armyworms ate the leaves of corn engineered to produce an insecticidal protein and lived, according to 2012 field trial data presented Nov. 13 at a conference in Knoxville, Tennessee. The protein is marketed by Dow and DuPont as Herculex.
