Performance of Single and Sequential Applications of Dicamba and Glyphosate on Weed Control in Dicamba‐Resistant Soybean

New Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
The Intacta 2 Xtend system was developed to allow selective dicamba use in dicamba‐resistant soybean (DRS), aiding in the management of tolerant and resistant broadleaf weeds. This study evaluated the control of broadleaf weeds following single or sequential postemergence applications of dicamba (alone or tank‐mixed with glyphosate) in DRS. Experiments

INVESTIGATION OF THE MECHANISM OF RESISTANCE TO GLYPHOSATE HERBICIDE IN HAIRY FLEABANE [PDF]

Planta Daninha, 2016
The resistance of weeds to herbicides is a consequence of one or more mechanisms in the plant, responsible for not allowing the herbicide to act properly at the active site. The objective of this study was to investigate the mechanism(s) of resistance to

Strip Crops and Intercrops Outperform Crop Rotations for Weed Management Under Conservation Agriculture in Zimbabwe

Weed Research, Volume 66, Issue 1, January/February 2026.
ABSTRACT High weed infestation remains a major constraint on crop productivity for smallholder farmers practising Conservation Agriculture (CA). Fewer, more diverse weeds are desirable to reduce competition and provide ecosystem services. Crop diversification can help, but it is not yet clear which species combinations and layouts are most effective ...
