OH2 Ornamental Herbicide Safe and effective pre-emergent control of broadleaf and grassy weeds.

Broad control

Save time and money with OH2

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.

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 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.

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.

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.
