In October of 2001 the Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA) approved the use of transgenic Bt, Bacillus thuringiensis Berliner sweet corn, Zea mays L. varieties. A major pest of sweet corn in Virginia, the corn earworm, Helicoverpa zea (Boddie) exerts significant pressures leading to greater than 90% loss of untreated fresh market quality sweet corn. In the fall insect pressures make sweet corn production prohibitive. This has led to speculation about the performance of Bt sweet corn in Southern Virginia and its public acceptance. It is possible that the use of Bt sweet corn can expand the growing season in Southern Virginia and possibly reduce the number of pesticide sprays. Experiments were begun testing 3 varieties of Bt sweet corn (BC 0801, BSS 0977, GSS 0966) against their non-Bt isolines (Bigtime, Prime Plus, Jackpot) to evaluate pest resistance.
