ABSTRACT
Deltapine Seed's 1998 Agronomic Services testing program in the North Carolina, South Carolina and Virginia included Roundup-Ready and Roundup-Ready/Bollgard trials. These field trials were conducted under grower management with emphasis placed on the technology of each variety. In general, the transgenic varieties performed very similar to their recurrent parents as well as other conventional varieties of the same maturity. Comparisons were made under two scenarios. The first comparison is a Roundup-Ready system with all varieties receiving a minimum of one application of Roundup Ultra® at the labeled rate. The second scenario included Roundup-Ready varieties under a conventional system. The third scenario is Roundup-Ready varieties in a side by side comparison with their recurrent parent. These three comparisons were made at different locations.
