OH2 Herbicide

Efficient and cost-effective broad-spectrum herbicide

OH2 combines the action of two proven herbicides in one granule. This unique combination results in broad spectrum pre-emergent weed control of both broadleaf and grassy weeds. One application controls weeds for up to three months. OH2 has been tested for safety on over 100 ornamental crops. It is the safest and most reliable pre-emergent herbicide to apply to containerised plants. OH2 sticks to the surface of growing media and soil. It is non-mobile, so will not leach in sensitive growing environments. OH2’s effectiveness at half the application rate of alternative herbicides ensures its use is very economical.

  • Specifically designed for nurseries and landscaping to control weeds around: container-grow ornamental trees and shrubs, contained garden beds and pots and field-grown ornamental plants

  • Tested for safety to use on over 100 ornamental crops

  • Up to three months of control with just one application

  • OH2 costs less than alternative control measures

Tips for optimum OH2 performance:

  • When applied over the top of the crop, OH2 should be applied when foliage is dry to prevent granules sticking to the plant. If necessary, wash OH2 off leaves after application.
  • For best results, water plants before application to settle and firm down the soil.
  • When foliage is dry, evenly distribute granules at the correct application rate over the entire soil surface

ICL provides the tools to determine the correct rate and distribution and to increase accuracy and efficiency of application. OH2 calibration cards, nursery weed management guides and OH2 hand shakers are available free from your local ICL distributor.
