Benchmark Studies - Glyphosate Resistance Management

Weed scientists from six universities have joined forces to examine grower weed management practices and develop programs to evaluate and improve the sustainability of weed control in Roundup ReadyŽ cropping systems. Called the Benchmark Study, this multi-state research project is now in its fourth year.

The Benchmark Study began in the winter of 2005-2006 with a telephone survey of 1200 growers from six states. Growers planting Roundup Ready corn, soybean or cotton for a minimum of three years were included in the survey. This team of university weed scientists developed a survey that evaluated tillage practices, herbicide use patterns, grower perceptions of weed pressure, and their problematic weeds before and after adopting Roundup Ready cropping systems.
