Bollgard II, Monsanto line DPX-9C985-EB, was compared to Bollgard and conventional cotton in two field trials to determine efficacy against the Heliothine complex in cotton. In the Jefferson County trial where insect pressure was greatest, results indicated that there was significantly less damaged squares, less live larvae, and increased yield in Bollgard and Bollgard II plots compared to conventional cotton whether or not it was sprayed. The same trend was shown in the Lincoln County trial although significant differences were not shown.
