ABSTRACT

Bollgard II, Monsanto lines DPLX-01L90-D and DPLX-01W94-D, were compared to Bollgard and conventional cotton in Jefferson County, AR, to determine efficacy against the Heliothine complex in cotton during 2001 and 2002. In both trials, Bollgard and Bollgard II reduced square damage and the presence of live larvae throughout the growing season when compared to the untreated conventional variety. This increased control resulted in greater yields in Jefferson County. The Bollgard II varieties used both years (DPLX01L90D in 2001 and DPLX01W94D in 2002) maintained the Heliothine larvae numbers and damage at very low levels for both years.
