Abstract
Three applications granular formulations of herbicides were applied broadcast over a 7-month period to budded citrus trees growing in 7.6 liters (4-gal) containers with a soil mix containing equal parts of peat, bark, and sand. Materials and rates at each application were alachlor + simazine 4.48 + 2.24 and 8.96 + 2.24 kg/ha; oryzalin 5.60 and 11.20 kg/ha; trifluralin 5.60, 11.20 and 22.40 kg/ha; oxadiazon 4.48 and 8.96 kg/ha; napropamide 11.20 and 22.40 kg/ha; and alachlor 11.20, 22.40 and 44.80. Good to excellent weed control was obtained at all rates of all herbicides used with no phytotoxicity to citrus trees observed.
