| Abstract/Contents: | "Influence of turfgrass age on development of gray leaf spot of `Rebel III' tall fescue was evaluated in controlled environment chambers. Four- to eleven-week-old tall fescue plants were inoculated with conidia of Pyricularia grisea and disease incidence (DI) (% leaves infected), disease severity on leaf blades (DSL), and disease severity on potted-turf (DSP) were evaluated 5 days after inoculation. The effects of turfgrass age on DI, DSL, and DSP were significant (P = 0.001). DI, DSL, and DSP were negatively correlated (r2 = 0.64, P = 0.03; r2 = 0.30, P = 0.02; and r2 = 0.81, P = 0.02, respectively) with turfgrass age. DI, DSL, and DSP may be estimated by the quadratic models y = 115.9 - 12.1x + 0.49 x2, y = 5.63 + 0.35 x = 0.4 x2, and y = 6.35 + 0.93 x = 0.12 x2, respectively, whre x = age in weeks. Additionally, DSL and DSP were positively correlated with DI, and they may be estimated by linear models yDSL = 2.87 + 0.05 x (r2 = 0.43, P = 0.0001) and yDSP = -0.35 + 0.12x (r2 = 0.61, P = 0.0001), respectively, where x = DI. The predictive models may be applied in the development of a disease management program following turf overseeding or re-establishment." |
