Bollworm is a key pest of cotton in the Mid-South. Economic damage can result when bollworm infestations occur after flowering, damaging reproductive plant tissue. In order to understand the efficacy of current commercial varieties controlling bollworm, experimental plots were established during the summers of 2011, 2012, and 2013. One Bollgard II® and one WideStrike^TM cultivar were planted each year. Their control of bollworms was significantly greater than a conventional cultivar but they were not significantly different from each other.
