Control Tips

Broad Sweep Broadleaf Herbicide is registered for the control Hemlock.

 

When using Broad Sweep in a high volume spraying situation:

  • Spray to thoroughly wet all the foliage but not to cause run off

  • Spray when the plant is actively growing

  • Use a high quality non ionic wetting agent like Weed Forces Holdfast for best results helping to improve wetting and herbicide penetration of the plant foliage


  • DO NOT spray when the plant is stressed (i.e. Drought, physical damage, insect damage, frost)
