Weed Control with Gallery and Other Herbicides in Field-Grown Nursery Crops

Abstract

Abstract Selected herbicides were evaluated for weed control in a two-year field test with boxwood, holly, viburnum and nandina. Gallery (isoxaben), when applied alone, generally provided inferior grass control during year one compared to Surflan (oryzalin). Surflan in combination with Gallery at 3.4 + 1.1 kg/ha (3.0 + 1.0 lb/A) provided weed control similar to that obtained with traditional herbicide programs of Surflan in combination with Princep (simazine) and/or Goal (oxyfluorfen). Plant size of four woody plant species, treated twice annually with Surflan + Gallery over a two year period, was statistically equivalent to the maximum plant size obtained with any other treatment.
