Preemergence and early postemergence control of many annual broadleaf weeds and preemergence control of many annual grasses in established container and field grown woody ornamentals. Typically used as a directed application to avoid injury to desirable foliage but can be broadcast applied to some conifers. Often tank mixed with a non-selective herbicide, such as glyphosate, for POST and PRE weed control.

Most annual broadleaf weeds common in container and field grown nursery crops including: bittercress, spurge, woodsorrel, phyllanthus, groundsel, chickweed, morningglory, doveweed, horseweed, liverwort and others. Eclipta control has been good at some locations and fair at others. Acceptable control of crabgrass is achieved but control declines with reduced dose and over time. Primarily used preemergence but will control many small seedling broadleaf weeds.

Nutsedges are not controlled. Sometimes weak on pearlwort, chickweed, evening primrose, marsh parsley and annual grasses.

Apply before weeds emerge. Irrigate immediately following treatment. Postemergence applications should be applied to seedling weeds. Older weeds will be injured but not killed. Tank mixes with non-selective postemergence herbicides (such as glyphosate or glufosinate) will improve postemergence weed control.

Do not apply over the top of broadleaf ornamentals. Do not apply in greenhouses if plants are present. Do not move plants into treated greenhouses until 24 hours after the treated area has been irrigated.

Two to three months of annual broadleaf weed control. Somewhat less for annual grasses and eclipta.

Moderately volatile but readily absorbed by soil organic matter. Leaching is not expected to be significant.

The most common injury symptom is localized necrotic spots (contact burn) on leaves and green stems contacted by the spray. Symptoms develop rapidly, within days. Herbicide is generally not systemic, but in some susceptible species young plants (e.g. wax myrtle and spiraea) development of red pigments in the main veins of leaves, suggests translocation. Mode of action: protoporphyrinogen Oxidase (PPO) Inhibitor. Mode of action Group 14.
