Time for a spring clearout of troublesome weeds

摘要

Despite the amount of herbicide that was applied before Christmas, some tidying up of broad-leaved weeds will be required this spring, especially after the wet winter. This season's generally well-established autumn-sown crops will be competitive andhelp crowd out many weeds, although record rainfall in January may have affected some herbicides. "The very wet winter does mean the length of activity of residuals might be curtailed," warns Nick Myers, national agronomy manager at advisory group ProCam.
