| Abstract/Contents: | "The effects of silicon on development of gray leaf spot in perennial ryegrass (Lolium perenne L.) turf was evaluated in two golf courses in Pennsylvania. The experiments were set up in a split-plot design with source of silicon (treatments:wollastonite and calcium silicate slag) as main-plot factor and rate of silicon amendments (treatments: 0, 0.5, 1, 2, 5 and 10 metric ton/ha) as split-plot factor. Silicon was incorporated into soil by core-aerification. Nine weeks after application of silicon, the grass was inoculated with a monoconidial suspension of M. grisea (60 ^D#^DOE 103 conidia/ml H2O). Disease assessments were made weekly as visual estimates where 0 = no blighting and 100 = entire plot area blighted. Disease progress over time was evaluated using the parameter estimates (rate r, Ymax and AUDPC) to determine the treatment effects. Results show that AUDPC and final disease severity were significantly reduced by silicon amendments in both sites. Rate of disease progress was significantly reduced only in one site. Gray leaf spot severity was also significantly reduced on several individual assessment dates. Results of this study indicate that application of silicon may be used as integral part of a gray leaf spot management strategy." |
