ICL OH2 Ornamental Herbicide

Safe and effective pre-emergent control of broadleaf and grassy weeds.

OH2 Benefits

• 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

Broad control

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 pre-emergent herbicide is specifically designed for nurseries and landscaping to control weeds around:

• container-grown ornamental trees and shrubs
• contained garden beds and pots
• field-grown ornamental plants

Safety

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.

Save time and money with OH2

Weed control with OH2 costs less than alternative control measures. The correct use of OH2 saves you time and labour costs by drastically reducing the amount of hand weeding required in containers and garden beds. With the time saved you are free to do what you do best: caring for and nurturing plants and gardens.

OH2’s effectiveness at half the application rate of alternative herbicides ensures its use is very economical.

Note: 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.

How to use

1. Avoid applying when small plants are putting on a flush of growth or breaking dormancy
2. Ensure there is plenty of air movement around the plant
3. Apply at least two weeks before moving plants into a greenhouse
4. Low growing soft annuals and perennials may experience leaf scorch

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
