| Abstract/Contents: | "Pathogenicity of Pyricularia grisea, causing blast disease (gray leaf spot) of perennial ryegrass (PR), on 4 to 11-week-old Penncross creeping bentgrass (CB) and Merit Kentucky bluegrass (KB) was evaluated in controlled-environment chambers. Symptoms developed on CB and KB seven days after inoculation with P. grisea (104 conidia/ml H2O), and the fungus was isolated from inoculated grass blades. The effects of turfgrass age on disease incidence were significant (P=0.0001) for CB, KB, and PR; however, the effects of age on disease severity was significant only for PR. Disease incidence was negatively correlated with the age of PR, CB and KB. Disease incidence for PR and CB may be estimated by linear models, y=9.39-0.51x and y=29.63-2.42x, respectively, and for KB, a quadratic model, y=91.08-16.44ix+0.84x2, where x=plant age. Similarly, disease severity for PR may be estimated by a linear model, y=105.9-3.9x. This study suggests that creeping bentgrass and Kentucky bluegrass are susceptible to P. grisea, and that a field survey for disease detection, especially in the overseeded or newly established turf, is warranted." |
