DISEASE ALERT- DOLLAR SPOT

摘要

During the past few months, some advisory staff have seen a noticeable increase in the amount of dollar spot (Sclerotinia Homoeocarpa) on golf courses. Over the years this disease has been observed from tune to time, particularly on bowling greens (and especially those that still have a significant red fescue content from previous establishment with Cumberland or sea washed turf). Golf courses in the south of the country seem to have borne the brunt of the increase hi dollar spot disease outbreaks which have been prevalent on a wide range of turf composition, but with fescue-dominated fairway turf suffering particularly badly. I have recently visited a well-known golf club where most fairways on one of their courses were very badly affected, to thepoint where if you threw your hat down, it would cover a dollar spot patch! Worrying times for the Courses Manager at this particular club where several greens (comprising bent and annual meadow-grass) were also showing signs of the disease.
