| Abstract/Contents: | "Zoysiagrass has become the most widely used turfgrass for high-end golf course tees and fairways. Large patch, caused by Rhizoctonia solani AG2-2 (LP), is the most destructive and wide-spread disease of zoysiagrass in the transition zone that includes Northwest Arkansas. The disease primarily attacks leaf sheaths in the spring and fall, causing irregular patches of necrotic turf up to several meters in diameter. The objective of this study was to determine the spatial and temporal distribution of large patch across seasons. Three 14 m ^D#x 7 m plots were permanently marked around areas where large patch disease was active. Patch locations in a plot area were recorded using a template divided into 100 cm2. Mapping of large patch symptoms indicated that patches occurred in the same area from season to season and the diseased area increased over time even though fungicides were applied. Aerification at one course when disease was active likely caused numerous new patches to develop. Current management practices are inadequate and should consider the cumulative effects of disease over time. Furthermore, large patch was observed to develop earlier than anticipated in late summer, indicating the current recommendations for timing fall fungicide applications maybe be too late." |
