AB Pre-emergent fall applications of alachlor (Lasso) and oxadiazon (Ronstar) singly or in combination with linuron (Lorox) or simazine (Princep) exhibited in some cases excellent weed control in excess of 9 months in a Skyline honeylocust planting. Alachlor when applied at the 6.0 lb AIA (active ingredient per acre) rate controlled annual grass weeds 10 months after application. Oxadiazon exhibited excellent control of both annual grasses and broadleaf weeds at all rates except when used singly at 3.0 lb AIA. In addition, some control of bigroot morning glory (Ipomea pandurate) was observed with oxadiazon. Sequential applications of glysophate (Roundup) controlled weeds in the nursery situation with no phytotoxicity to the skyline honeylocust trees.
