Abstract/Contents: | "Optimum top growth of annual bluegrass (Pao [Poa] annua L.) and Kentucky bluegrass (Poa pratensis) was obtained at 24/12°C day/night temperature regime in controlled environment studies. The tolerance of seedling Kentucky bluegrass to linuron [3-(3,4-dichlorophenyl)-1)methylurea] appeared to be greatest at this temperature regime when photoperiods were greatest at this temperature regime when photoperiods were 16 h in length. A granual formation of linuron gave excellent control of annual bluegrass in Kentucky bluegrass turf at 6.7 kg/ha when applied postemergence. At this rate, all culitivars [cultivars] of Kentucky bluegrass tested, with the exception of Fylking, were tolerant to linuron as a granular formulation. After application of linuron granular at 3.4-6.7 kg/ha, phytotoxic residues remained in the soil at sufficient levels to injure seedling Kentucky bluegrass for up to 3 mo." |
