| Abstract/Contents: | "Zoysiagrass (Zoysia japonica and Z. matrella) is a warm-season (C4) turfgrass that is appropriate for many uses in the central and southern United States. Large patch, caused by Rhizoctonia solani AG 2-2 LP, is the most common and severe disease of zoysiagrass and is managed primarily by fungicides. The effects of cultivation (aerification, verticutting and sand topdressing) and time of nitrogen (N) fertilization on large patch development were evaluated on inoculated plots in a split-plot design with four replications. The whole plot treatment was cultivation vs no cultivation. The subplot treatment was fertility, with either polymer-coated urea equivalent to 2 lb N per 1000 ft2 applied as one application during summer or as split applications of urea at 1 lb N each during spring and fall. Large patch severity was assessed through patch size measurements and digital image analysis. Patch sizes were significantly reduced in 2009 but not in 2008 in cultivated plots. Cultivation and summer fertilization resulted in smaller patches compared with noncultivation and fertilization in spring and fall. However, recovery of zoysia from large patch infection during summer was faster in non-cultivated plots, irrespective of the timing of fertilization, than in cultivated plots. Cultivation and summer fertilization could potentially reduce the fungicide volume required for large patch management." |
