Introduction

Trade Name: Gallery Common Name: isoxaben Formulation: 75 DF, 4.16 SC

Uses

Preemergence broadleaf weed control in established turf, field- and container-grown ornamentals, groundcovers, nursery stock, ornamental bulbs, Christmas tree plantations, and non-bearing fruit trees.

Amount of Active Ingredient Amount of Formulation Herbicide
75 DF 4.16 SC
Per Acre 0.5 to 1.0 lb 0.66 to 1.33 lb 16 to 31 fl oz
Per 1,000 sq. ft. 0.25 to 0.5 oz 0.3 to 0.7 fl oz

Major Weeds Controlled

Many broadleaf weeds including chickweed, bittercress, oxalis, horseweed, dogfennel, and spurge.

Major Weeds Not Controlled

Velvetleaf, mallow, morningglory, cutleaf evening primrose, phyllanthus, willowherb, doveweed, sedges, annual grasses, most perennials, and established weeds.

For Best Results

Apply to weed-free soil. Needs 12-inch of water to activate. Generally mixed with a preemergence grass herbicide such as Suflan, Pendulum or Barricade to expand the spectrum of weeds controlled. See label for additional information.

Cautions and Precautions

Do not apply to newly transplanted plants until the media or soil has settled and no cracks are present. Do not apply to bedding plants or areas where bedding plants will be planted within the next year. Do not apply to groundcovers until they are well rooted. Do not apply more than 4 pounds of Gallery in 12 months, and repeat applications of 1 pound per acre should not be applied less than 60 days after the previous application. Injury to Euonymus alatus compacta, Hydrangea spp., hybrid lilac, ajuga, yucca, foxglove, stachys, some Veronica spp. and several bedding plant species have been reported. See label for details and additional precautions.

Residual Activity

Length of residual weed control varies considerably. In the southeastern United States, 60 to 90 days of residual weed control can be expected. Residual control in the Northeastern U.S. and similar climates may be considerably longer; over 6 months residual control of susceptible broadleaf weeds has been reported in the western and Northeastern United States. In container nursery crops, residual weed control typically lasts no more than 60 days.

Volatility and Leaching Potential

No significant photodecomposition or volatilization occurs with field use. Slightly susceptible to leaching and surface runoff in poorly drained soils.

Symptoms and Mode of Action

Appears to disrupt root and hypocotyl development by inhibiting cell wall synthesis. HRAC Group L; WSSA Group 21.
