| Abstract/Contents: | "Rapid blight, caused by Labyrinthula terrestris (D.W. Bigelow, M.W. Olsen, and Gilberston), increases with increasing irrigation water salinity. Irrigation water from Western (WW) and Eastern (WE) coastal regions of the United States, where rapid blight occurs, have different levels of mineral constituents contributing to salinity. WW primarily differs from EW salinity in having higher Ca and slightly lower Na. Isolates of L. terrestris from each region have different salinity optima in vitro as well. Several experiments were conducted in a greenhouse environment to evaluate differences in isolate pathogenicity and irrigation water composition on the occurrence of rapid blight in perennial ryegrass. At nearly equivalent salinity levels, measured by electrical conductivites, irrigation water with lower levels of Ca but higher levels of Na indicative of EW sources resulted in substantially more rapid blight than higher levels of Ca indicative of WW sources. Ryegrass shoot moisture content and shoot dry weight decreased with inoculation and concentration of 2.4 and 4.6 dSm-1 and was reduced more with EW irrigation than with WE. Perennial ryegrass plants irrigated with EW and infected with rapid blight also accumulated more Na and less K in leaves compared to infected plants that were irrigated with WW. Differences in pathogenicity among isolates from the two environments were minimal." |
