Rootworms used to cause billions of dollars of damage to U.S. crops until Bt corn was genetically altered to be poisonous to the rootworms. Currently, Bt (Bacillus thuringiensis) corn makes up three-quarters of the U.S. corn crop. With its implementation, farmers have been able to cut down on insecticides and cause less ecological damage. Warnings early on suggested keeping refuges of planted non-Bt corn so that rootworms would ultimately remain susceptible.
