Following generally strong autumn weed control, growers must now decide how best to manage surviving and spring- emerging grassweeds and make the appropriate control choices. Hutchinsons technical manager Dick Neale says Autumn residual herbicides have performed well overall. In the main, weaker results have largely been limited to early-drilled crops or where dry conditions restricted activation. “In many dry situations, lower-cost products were used initially, followed by more robust residual options once rainfall arrived,” he explains. “That strategy, combined with wider use of mixtures containing cynmethylin, bixlozone, aclonifen, metribuzin, flufenacet and diflufenican, has driven improved control.” Sequencing has also played…
