DP50, 50B and 50BII were planted August 1, 2001 in Escambia County, Alabama. Plants grew slowly because of the relative cold temperatures, and frost on Nov. 4, 2001. On Nov. 10, neonate CBW were placed in white blooms on ten plants per treatment replicated five times. After 7 days, DP50 had 54% boll damage, and DP50B and DP50BII had no boll damage. Additionally, DP50B had 16% aborted bolls whereas DP50BII had only 8% aborted bolls. These results show that even under extreme conditions, Bollgard and Bollgard II provide excellent control against CBW.
