Dual and Frontier • Some control/suppression of broadleaf
weeds – Eastern black nightshade and
pigweed – Frontier provides greater broadleaf weed
suppression • Dual is more consistent on yellow nutsedge • Pursuit tankmix (PPI or PRE)

• Marginal chlorosis of the unifoliates followed by necrosis

• Delay in plant development

• On small seeded market classes (white & black)
• When applied PRE (PPI is safer)
• When heavy rainfall occurs at bean emergence following a PRE application
• If the beans have started to emerge
• On coarse-textured soils low in organic matter
– Use the lower rate on the label
