Soybean varieties that incorporate the use of Roundup Ready biotechnology have become the most successful genetically altered crop yet to be established. But glyphosate resistant weeds have resulted in major production problems for all crops with yield losses, decreased harvest efficiency, and increased input costs.

In order to evaluate soybean cultivars that will improve Georgia soybean production, field and growth chamber trials that emphasize metrubuzin tolerance must be considered. Metribuzin can provide residual weed control, help to improve yield, and increase profitability. Therefore, a study comparing the most commonly used Roundup Ready, LibertyLink, and newly introduced...
