Glyphosate resistant waterhemp control through cost effective combinations of pre-emergent and early post-emergent residual herbicide applications in soybean.

Glyphosate resistant waterhemp is a widespread problem throughout Minnesota and the Midwest. First confirmed in Minnesota in 2007, waterhemp is known to be more difficult to control compared to most weed species; additionally, misapplication and overuse of post-emergent herbicides has led to selection pressure in waterhemp populations

Known glyphosate resistant bio-types in counties in southwest Minnesota continue to prevail through post-emergence herbicide programs. In a down farm economy, every little bit helps, and economical applications will provide the greatest value added to the grower.
