Influence of glyphosate/dicamba application rate and timing on the control of glyphosate-resistant waterhemp in glyphosate/dicamba-resistant soybean

Influence of glyphosate/dicamba application rate and timing on the control of glyphosate-resistant waterhemp in glyphosate/dicamba-resistant soybean

The objective of this study was to determine the effect of premixed glyphosate/dicamba application timing and rate on glyphosate-resistant (GR) waterhemp control. Glyphosate/dicamba applied to 5-, 15-, and 25-cm-tall plants, controlled GR waterhemp 81%, 73%, and 61% at 2 wk after application (WAA) a...

Zusammenfassung:The objective of this study was to determine the effect of premixed glyphosate/dicamba application timing and rate on glyphosate-resistant (GR) waterhemp control. Glyphosate/dicamba applied to 5-, 15-, and 25-cm-tall plants, controlled GR waterhemp 81%, 73%, and 61% at 2 wk after application (WAA) and 61%, 68%, and 72% at 8 WAA, respectively.
