Spring-tillage has no effect on the emergence pattern of glyphosate-resistant giant ragweed (Ambrosia trifida L.) in Nebraska

Abstract

The objective of this study was to investigate the effect of spring tillage on glyphosate-resistant giant ragweed emergence pattern. Giant ragweed emerged from late Mar. until early June and tillage had no effect on total seedling emergence and days required to reach 50% cumulative emergence (T50); however, results differed between years.
