Field studies conducted for 2 years showed that glyphosate [N-(phosphonomethyl) glycine] or mixtures of glyphosate and preemergence herbicides applied as preplant and directed postplant sprays were effective in providing season-long weed control in commercial nurseries. Oryzalin [3,5-dinitro-N 4,N 4-dipropylsulfanilamide] at 2.2 or 4.5 kg ai/ha, and mixtures of simazine [2-chloro-4,6-bis(ethylamino)-s-triazine] at 1.1 kg ai/ha with diphenamid [N,N dimethyl-2,-2-diphenylacetamide] at 6.7 kg ai/ha, napropamide [2-(α-naphthoxyl)-N,N-diethylpropionamide] at 2.2 kg ai/ha, alachlor [2-chloro-2’,6’-diethyl-N-(methoxymethyl) acetanilide] at 2.2 kg ai/ha or oryzalin at 4.5 kg ai/ha were effective treatments when used after preplant application of glyphosate (2.2 kg ai/ha) or when combined with glyphosate (2.2 kg ai/ha). None of the herbicide treatments reduced growth of red maple (Acer rubrum L.), Norway maple (A. platanoides L.), or creeping juniper (Juniperus horizontalis Moench). Japanese spurge (Packysandra terminalis Sieb. and Zucc.) survival was reduced by treatments containing oryzalin.
