Comparison Of Different Weed Control Technology Programs, D. E. Peterson, C. Thompson, C. L. Minihan

Kansas Agricultural Experiment Station Research Reports

The development of glyphosate-resistant weeds has greatly complicated weed control in soybeans. Roundup Ready 2 Xtend and Liberty Link soybeans provide an alternative postemergence herbicide options for weed control in soybeans. Liberty Link and Roundup Ready 2 Xtend programs provided better overall weed control and slightly higher yields than Roundup Ready 2 Yield programs in this experiment. Yields of Roundup Ready 2 Yield soybeans were likely influenced by more weed competition and possibly crop injury from spray tank contamination by dicamba. Dicamba injury from tank contamination to Roundup Ready 2 Yield soybeans decreased with each subsequent treatment and also with …


Two Pass Weed Control Programs In Conventional Tillage Xtend Soybeans, D. E. Peterson, C. Thompson, C. L. Minihan Jan 2017

Two Pass Weed Control Programs In Conventional Tillage Xtend Soybeans, D. E. Peterson, C. Thompson, C. L. Minihan

Kansas Agricultural Experiment Station Research Reports

The development of glyphosate-resistant weeds has greatly complicated weed control in soybeans. Roundup Ready 2 Xtend (dicamba tolerant) soybeans provide growers an alternative herbicide option for postemergence weed control in conventional tillage soybeans. Two pass programs consisting of preemergence residual herbicides followed by postemergence Roundup Power Max plus dicamba provided excellent weed control, superior to a single postemergence treatment with Roundup Power Max plus dicamba.
