Bollgard II and WideStrike varieties and selected insecticides were evaluated for management of bollworm in Virginia.  Efficacy was assessed using in-field ratings of boll damage caused by larvae or live larvae.  Yields were determined using a standard cotton picker.  Value was determined using lint yields, estimated value, and costs.
