Preemergent weed control in container and field grown woody nursery crops with gallery

Two container and four field tests were conducted to evaluate Gallery (isoxaben) for preemergent weed control in container and field grown woody nursery crops. Gallery was applied to newly potted nursery crops at 0.56 and 1.1 kg ai/ha (0.5 and 1 lb ai/A) alone and in combination with Surflan (oryzal...

Description
Summary:Two container and four field tests were conducted to evaluate Gallery (isoxaben) for preemergent weed control in container and field grown woody nursery crops. Gallery was applied to newly potted nursery crops at 0.56 and 1.1 kg ai/ha (0.5 and 1 lb ai/A) alone and in combination with Surflan (oryzalin) or Treflan (trifluralin). No injury was observed on container grown Coral ‘azalea Bells,’ Rhododendron ‘Roseum Elegans,’ rockspray cotoneaster, forsythia, potentilla ‘Tangerine,’ Japanese dwarf garden juniper, ‘Old Gold’ juniper, or plaintain lily ‘Albo-marginata.’ Gallery, applied alone, caused no injury to field grown sawara false cypress, honey locust, Japanese yew, California privet, ‘San Jose’ holly, white pine, Douglas fir, white fir, green ash, or Japanese rose. Gallery injured field grown common lilac. When combined with Surflan, temporary reduction in white fir and Japanese barberry quality resulted. Douglas fir was injured significantly by Surflan, alone or in combination with Gallery. Gallery provided excellent control of many broadleaf weeds including pigweed, common groundsel, and dandelion, but poor control of annual grasses such as crabgrass, goosegrass, and fall panicum. The combination of Gallery plus Surflan provided an expanded spectrum of weed control with excellent safety on most container and field grown woody nursery crops.
