ABSTRACT
Nineteen-ninety-nine was the second year of an ongoing study designed to examine the cost and returns associated with alternative pest control systems using transgenic and conventional cotton varieties. Ten varieties of conventional and transgenic seed were grown using Best Management Practices with the goal of maximizing profits. Per acre cost of insect and weed control and returns were determined for each treatment. Some of the transgenic varieties offer increased net returns over some of the conventional varieties.
