David Woodske, industry specialist (ornamentals) with the British Columbia Ministry of Agriculture and Lands, has been informed of a new turfgrass disease which has been confirmed on a turf sample submitted from a golf course in Kelowna.
The causal organism for brown ring patch is Waitea circinata var. circinata. The pathogen is considered to be an emergent disease of turfgrass in the U.S. It has been isolated from annual bluegrass samples obtained from California, Connecticut, Idaho, Illinois, Massachusetts, New York, Ohio, Oregon, and Rhode Island. As far as lab records are concerned, this is a first report for British Columbia.
Since the pathogen is widely distributed in the U.S., no trade implications are anticipated on exported sod…if the disease is ever found on a sod farm.
