| Abstract/Contents: | "The effects of silicon (Si) on development of gray leaf spot (GLS) in perennial ryegrass (Lolium perenne L.) (PR) turf was evaluated. The experiment was set up as a split-split-plot design with soil types as mainplot factor (peat:sand mix with Si 5 ppm (PSM) and Hagerstown silt loam with Si 70 ppm (HSL)), sources of Si as split-plot factor (Wollastonite and Calcium silicate slag), and rate of Si (0, 0.5, 1, 2, 5, and 10 metric ton/ha) as split-split-plot factor. Nine-week-old PR grown in Si-treated soil was inoculated with M. grisea (3.5 ^D#x 104 conidia/ml H2O). Disease incidence (DI) and severity (DS) were assessed two weeks after inoculation. Si content in plant tissue significantly increased with increasing levels of Si in both soil types (P ≤ 0.05). DI and DS were significantly lower (P ≤ 0.05) in plants grown in Si-treated PSM than those grown in non-amended control. Similar results were obtained in HSL. Results of this study indicate that Si can be suppressive to GLS of PR turf; however soil type may infulence the magnitude of this response." |
