Six herbicides and selected combinations were evaluated on four field-grown woody landscape crops: live oak, ‘Mary Nell’ holly, ‘Chesapeake’ viburnum, and ‘Acoma’ crapemyrtle. All herbicide treatments provided excellent control of goosegrass (Eleusine indica (L.) Gaertn.). Treatments with Predict (norflurazon) provided adequate sicklepod (Cassia obtusifolia L.) control. Only Goal (oxyfluorfen)-containing treatments controlled cutleaf eveningprimrose (Oenothera laciniata Hill). Predict and Predict treatment-combinations bleached older foliage of crapemyrtle and viburnum when applied in the first year after planting; however, growth was not affected. Holly was not injured by any herbicide treatments. Pendulum (pendamethalin) and Surflan (oryzalin) had similar weed control activity and plant growth with no plant injury
