| Abstract/Contents: | "Amicarbazone (triazolinone) and flucarbazone (triazolone) are currently being evaluated for use in turfgrass. Research was conducted to evaluate emerald zoysiagrass (Zoysia japonica x Z. tenuifolia) tolerance and winter broadleaf weed control with these compounds. Two experiments were initiated January 2008 and evaluated the same treatments at two different locations. Treatments evaluated were: amicarbazone at 0.26 and 0.52 kg ai/ha; flucarbazone at 0.03 kg ai/ha, metsulfuron at 0.14 kg ai/ha, and a non-treated control. Treatments also included combinations of amicarbazone and flucarbazone at the above listed rates. Treatments were replicated four times. A non-ionic surfactant was added to all treatments at 0.25% v/v. Applications were made with a backpack sprayer calibrated to deliver 280 L/ha. Experiment one evaluated percent control of henbit (Lamium amplexicaule), narrowleaf vetch (Vicia sativa), bristly mallow (Modiola caroliniana), and dichondra (Dichondra carolinensis). Percent control of henbit, Carolina geranium (Geranium carolinaianum), common chickweed (Stellaria media), and Florida betony (Stachys floridana) were recorded over time in experiment two. Henbit control in experiment one was excellent (>90%) 31 days after application (DAA) with all treatments containing amicarbazone. Metsulfuron provided 85% control of henbit. Flucarbazone applied alone failed to provide any control or suppression of this species. Amicarbazone at 0.52 kg/ha applied alone as well as both rates of amicarbazone in combination with flucarbazone provided >98% control of narrowleaf vetch. Control with metsulfuron, amicarbazone at 0.26 kg/ha, and flucarbazone alone had little effect on this species, providing only 34, 13, and 5% control, respectively. Control of bristly mallow and dichondra were taken 110 DAA. Bristly mallow was controlled best with metsulfuron and the tank mix of amicarbazone at 0.52 kg/ha + flucarbazone, providing 96 and 90 %, respectively. Amicarbazone at 0.52 kg/ha provided the highest control of dichondra, 88%. In the second experiment, control of henbit 32 DAA was similar to that seen in experiment one. However, at 56 DAA, control had fallen for all treatments except metsulfuron (99%). Control with amicarbazone alone was 78 and 81%, respectively, for the 0.26 and 0.52 kg/ha rates. Combinations of amicarbazone+flucarbazone failed to control henbit 56 DAA. Only metsulfuron provided acceptable levels of control of Carolina geranium, common chickweed, and Florida betony 56 DAA, with control being >98% for all. Control of Carolina geranium and Florida betony was <40% with all other treatments. Control of chickweed was marginal, ranging from 43-65% with remaining treatments. A study was initiated August 2008 to evaluate emerald zoysiagrass tolerance. Treatments were: amicarbazone at 0.26 and 0.52 kg/ha with both single and repeat applications; flucarbazone at 0.03 kg/ha; and amicarbazone 0.26+flucarbazone 0.03 kg/ha. Repeat applications were made three weeks after the initial application. Zoysia injury was recorded over time. Injury from initial applications from all treatments was 31-38%, 10 DAA (30% considered unacceptable). However, injury had fallen to acceptable levels one week later. Highest injury from repeat applications was observed for the high amicarbazone rate at 38%, with all others being within acceptable limits. Six weeks after initial application, highest injury was recorded for the high rate of amicarbazone at 27%." |
