OH2 Pre-Emergent Herbicide 22.7kg

Newly-Transplanted Container or Field Nursery Stock

• Apply after cuttings form roots and are established. To avoid inhibition of the tissue union, apply before budding/grafting or after buds/grafts have taken. Do not apply to wet foliage or to pots less than six inches wide.

Established Container, Field Nursery Stock, or Landscape Plants 

• Apply at any time as an over-the-top, or soil directed application.

Landscape (or Ornamental) Plantings 

• Apply as an over-the-top, or as a soil directed application. Delay applications to newly transplanted ornamentals until soil has settled around transplants.

Bare Ground Application for Container Placement 

• Apply to soil (including mulch, gravel, wood chips, or other permeable base) upon which containerized ornamentals are placed. After application, use a post-emergence herbicide to control break  though weeds. If  necessary, perform shallow cultivation or hand weeding to avoid disturbing the herbicide barrier.

Shadehouses and Uncovered Polyhouses 

• Plants must receive two irrigations totaling at least 0.5 inches of water before covering. After application, houses must remain uncovered for at least 21 days.

Ornamental Bulbs (not for use on ornamental bulbs grown for commercial production in California)

• Apply before bulbs emerge. Do not re-apply after emergence.
